Chapter 1 Introduction to Command Line

The command line provides an interface between people and machine to communicate through command characters. The command line of the IAD132E(T) enables you to configure, operate and maintain the device. This chapter introduces the basic functions and features of the IAD132E(T) command line, including: command mode, operator authority, security features, operational features, error messages and switchover between command languages.

1.1 Command Modes and Operator Authorities

1.1.1 Command Mode

Table 1-1 shows the command modes provided by the IAD132E(T).

Mode Function Prompt Enter Exit

Lanswitch Configuring built-in LAN Switch data

IAD2000(lanswitch)#

Input “lanswitch” in privilege mode Input “lanswitch” in global config mode

Input “exit” to return to the privilege mode Input “config terminal” to return to the global config mode

Lanswitch-VLAN

Configuring built-in LAN Switch VLAN data

IAD2000(lanswitch-vlan-1)#

Input “vlan vlan-id” in Lanswitch mode

Input “exit” to return to the lanswitch mode

The command line prompt consists of two parts: “Fixed character string” + “command mode identifier”, in which the command mode identifier indicates the mode that the current command is in. For example: “>” means the user mode, “#” means the privilege mode. The fixed strings can be configured through the global configuration command hostname hostname.

The privilege mode and global mode are compatible with the lower-authority modes: in the privilege mode, you can execute the commands of the user mode; while in the global config mode, you can execute the commands of the user mode and privilege mode. Figure 1-1 shows the relationship among different command modes.

Figure 1-1 Relationship among different command modes

1.1.2 Operator Authorities

The IAD132E(T) has four levels of operator authorities in an ascending order of the priority: Root, Admin, Oper and Exec. The Exec can only execute the commands in the user mode. The Oper, Admin and Root can execute any commands of the


1-3

command modes. Meanwhile, in the same command mode, operators of different authorities may be able to execute different commands. For details, refer to Appendix A and Appendix B of this manual.

Note:

There are two default administrators of the system, one is the super administrator named “root”, and the password is “admin”. The other is the administrator named “system”, and the password is “login”.

1.2 Security Features of the Command Line

The command line provides these security features:

When an operator logs in the system, the input user name and password must be correct. Operators of different levels have different management authorities.

The input password is not displayed on the terminal screen. If incorrect password has been input for three consecutive times when an

operator logs in, the terminal will be disconnected from the device. If a terminal has been idle for a certain period of time (default as ten minutes,

and you can execute command terminal timeout to set the time) after the operator logs in, the terminal will be disconnected automatically. In this case, the operator must enter the password again to log in. This function can prevent illegal operation on the device by unidentified operators who make use of the identity of a legal operator.

To prevent illegal access of unidentified operator who makes use of the identity of a legal operator, the command line terminal can also be locked by an operator, so that the terminal is protected by a password. In the user mode, you can execute terminal hold clientid to lock the command line terminal. A higher-authority operator can also lock the command line terminal of a lower-authority operator, in order to restrict the operations that can be made from the terminal.

For example, if the super administrator “root” shall lock the command line terminal of the administrator “system” (Client ID is 2), the following two steps are needed:

1) Show information of the command line terminal. IAD2000> show client

------------------------------------------------------------------

Client ID Client Name IP Address Login Time

------------------------------------------------------------------

1 root 0.0.0.0 2002/11/24 12:08:23

2 system 201.21.100.25 2002/11/24 12:14:13

-------------------------------------------------------------------


1-4

2) Lock the command line terminal. IAD2000>terminal hold 2

Please input password(<=15 chars):

Confirm Password(<=15 chars):

This terminal has already been hold!

Terminal held, please input password(<=15 chars):

Caution:

If a command line terminal will be left unattended for long, the operator should exit the command line, or lock the command line, in order to ensure security.

1.3 Operation Features of the Command Line

1.3.1 Online Help

The command line of the IAD132E(T) provides online help in five modes:

You can execute the help command to obtain brief description on the help system:

IAD2000> help

Help may be requested at any point in a command by entering

a question mark '?'. If nothing matches, the help list may

be empty.

Two styles of help are provided:

1. Full help is available when you are ready to enter a

command argument ( e.g. 'show ?' ) and describes each

possible argument.

2. Partial help is provided when an abbreviated argument

is entered and you want to know what arguments match

the input ( e.g. 'show l?' ).

You can input ? after the command line prompt to obtain the help information for all the commands in this mode, as well as the commands in the lower modes:

IAD2000(config)#?

The display function is enabled, and the last line of input is displayed.

1.3.2 Smart Interaction

With the smart interaction function, you can just input part of a command word, or a complete command word but part of the parameters, then press <Enter> to display the type and range of parameters for such command. The optional command words and parameters will also be prompted. To ignore a command or parameter, just press <Enter>.

Table 1-2 shows the types of common parameters.

Table 1-2 Types of common values

Para. Type Meaning Example

S Character string {frame/slot<s>}<3,5>: frame/slot is a parameter in character string, the string has 3 to 5 characters.

I IP address {ip-address<I>}: ip-address is an IP address.

M Net mask {net-mask<M>}: net-mask is a mask of an IP address.

U Integral parameter (ulong)

{paranum<U>}<0,10>: paranum is an integral parameter, its value ranges from 0 to 10.

K Command keyword

{terminal<k>}: terminal is a command keyword that should be input directly.

E Enumerate (enum)

{ duplex-mode<E><half,full> }: duplex-mode is an enumerate parameter, which can be “half” or “full”.

T Time {inverse<T><hh:mm:ss>}: inverse is a time parameter, which is input in the form like hh:mm:ss.

YYYY-MM-DD Date {datebegin<YYYY-MM-DD>}: a date type parameter in the form

like YYYY-MM-DD

P MAC address {mac-address<P>}: a MAC address in the form like ab-cd-ef-gh-ij-kl

The command line also provides no smart command to disable the smart interaction function. After you disable this function, the command you input will be executed directly. To enable the smart interaction, just execute smart. By default, the smart interaction function is enabled.

For example, enter the global config mode from the privilege mode:

When smart interaction is enabled IAD2000#configure <cr>

{terminal<k>}:terminal <cr>


1-8

IAD2000(config)#

Input configure and press <Enter>, the command line will display {terminal<k>}.

When smart interaction is disabled IAD2000#configure <cr>

%Incomplete command, and error detected at '^' marker.

IAD2000#configure terminal<cr>

IAD2000(config)#

Input configure and press <Enter>, the command line prompts error. You must input the complete command: configure terminal.

Note:

The command smart can be used in user mode, privilege mode, global config mode, Lanswitch mode.

1.3.3 Intelligent Matching

You can use the <Spacebar> to automatically match the key words of the commands and parameters. This can avoid inputting of a long string of command and parameters, and facilitate your work. If the automatic matching is incorrect, you cannot continue the input of the next command or parameter. When you make this operation, you can see the complete command words. If you cannot get the auto-matching result with the <Spacebar> after inputting some of the commands, it means the command you input has multiple options, or the command you input is wrong. In this case, you should input more command characters, or check your input.

For example, in the user mode, input en and press the <Spacebar>, the command line will display enable:

IAD2000>en <Spacebar>

IAD2000>enable

IAD2000>eg <Spacebar>

Input eg, there is no matching result on the command line, which means there is no command that starts with “eg”.

The command to configure the call mode is call-mode. Enter call and press the <Spacebar>, and there is no matching.

IAD2000(config)#call- <Spacebar>

Use Help to query. It shows that conflict should be selected after call- is input.

IAD2000(config)#call-?

---------------------------------------------


1-9

Command of Global Config Mode:

---------------------------------------------

call-conflict Call conflict

call-mode call mode

After input call-c and press the <Spacebar>, the command line can automatically match.

IAD2000(config)#call-conflict

1.3.4 History Command

The last input commands will be stored in the system as history commands, and you can invoke these history commands anytime (you can only invoke the commands input by yourself) and execute these commands. You can execute history size to set the number of commands that can be stored in the buffer, the number ranges from 1 to 100.

There are two methods to query the history commands:

When you log in the device through Telnet connection, you can use the arrow keys “↑ ” and “↓ ” to show the history commands. When you log in the device through HyperTerminal, you can use <Ctrl+O> and <Ctrl+P> to show the commands.

You can also execute show history to show the history commands: IAD2000>show history

enable

configure terminal

smart

lag

language

show language

Note:

After you have used the arrow keys to show the command, you can press <Enter> to execute the history command. The history commands are valid only for current operator. If you log off, and then log in again, all the history commands will be cleared.


1-10

1.3.5 Screen Clearance

If you want to give more explicit display of the information, you can execute cls to clear the screen. After you execute the cls command, contents on current terminal screen will be cleared, and the command line prompt will display at the top left corner of the screen. The clear-screen function can be used in all the command modes except narrow band mode, interface configuration mode and Lanswitch mode.

1.3.6 Telnet Terminal Services

IAD132E(T) provides Telnet and terminal emulation functions.

Telnet server service

You can run Telnet client program on the maintenance terminal connected with IAD132E(T) and log in IAD132E(T) to configure and manage it.

Telnet client service

You can log in IAD132E(T) through terminal emulator or Telnet client, then input Telnet command to log in and manage other devices in the network.

Example:

IAD2000>telnet 172.21.100.41

Trying 10.21.100.41 ...

After you have input and executed the command, if the command is executed successfully, there will be no prompt message. If the command is not executed successfully, an error message will return.

1.5 Language Switchover of the Command Line

The command line supports multiple display languages. The default language is English, and you can load different language files for the online help. The language file of online help can be loaded and upgraded individually. Refer to U-SYS IAD132E(T) Integrated Access Device Installation Manual for the method to load and upgrade the language files.

After you have loaded or upgraded the language file, you can execute language in any command mode to switch the language of the command line, and execute show language to display the information about the language file.

1.6 Appointed Command Line Formats

The following formats apply to the commands introduced in this manual.


1-12

Format Meaning

In boldface Key words in a command line (the part in a command that remains unchanged and has to be input) are in boldface.

In italics Parameters in a command line (the part in a command that has to be replaced by actual values) are in italics.

[ ] The part in a “[ ]” is optional in command configuration.

{ X ∣ y ∣ …} Choose one option from two or multiple options.

[ X ∣ y ∣ …] Choose one option or no options from two or multiple options.

{ X ∣ y ∣ …} * Choose several options from two or multiple options. Choose one options at least and all options at most.

[ X ∣ y ∣ …] * Choose several or no options from two or multiple options.

For example:

The command to configure a semi-permanent connection (SPC) is as follows:

spc add start slotid/portid end slotid/portid iad-spc channelnum [ name spcname ]

The command line format has the following meaning: The parameter [ name spcname ] has a default value and hence is optional; all other parameters do not have a default value and have to be configured. start, end, iad-spc and name are key words; slotid/portid, channelnum and spcname are command line parameters.

The command to modify an SPC is as follows:

spc modify connectid {start slotid/portid | end slotid/portid | name spcname |local-port local-port | remote-ip remote-ip | remote-port remote-port }*

The command line format has the following meaning: At least one parameter of those in {}* has to b configured. You can also configure several or all parameters.

2-1

Chapter 2 Basic Configuration

This chapter takes a typical networking scheme as an example to present the data configuration process on the IAD132E(T). It first describes how to connect and configure the maintenance terminals, the configuration procedures and networking examples. Then it introduces in turn the basic data configuration, interface data configuration, and access user data configuration. At the end of the chapter, a summary is given on the configuration examples.

This chapter introduces the basic configuration of the IAD132E(T), based on which you make normal calls with the IAD132E(T). For adjusting the voice quality, configuring polarity reversal charging, and using the LAN switch, refer to Chapter 3 “Advanced Configuration”.

The IAD132E(T) also supports the IADMS and IAD hatchers. If IADMS is configured for the IAD132E(T), the data configuration and management of the IAD132E(T) can be fulfilled on IADMS. For details, refer to N2000 Fixed Network IADMS User Manual. The IAD132E(T) can work with the IAD hatcher to fulfill software upgrade and the initialization of the basic data. For details about the IAD hatcher, refer to IAD Hatcher User Manual.

2.1 Configuration Procedures The following data must be configured correctly to make the IAD132E(T) work normally: Data configuration includes the basic data configuration, interface data configuration, and access user data configuration. The configuration of the basic data is the most fundamental one. The configuration of the interface data and access user data can only be fulfilled after having checked the basic data configuration for correctness and validity. Figure 2-1 shows the configuration procedures.

Figure 2-1 Process of data configuration

Note:

The arrows in the above figure indicate that there are time sequences for configuring the data. After configuring a group of data, you can run the command show running-config in the privilege mode

to check the correctness of the configured data. Some of the data are default settings provided by the system, and if you have changed them, the changed ones will be displayed. The configurations that are taking effect at the time being will not be displayed if they are the same with the system defaults.

The basic data configuration includes the equipment information configuration and board configuration. You must make the configurations in strict sequence.

Configuration of the interface data includes the media gateway (MG) interface, MG interface data and the starting of the MG interface. You must make the configurations in strict sequence.

The access user data configuration includes the ordinary access user service and semi-permanent connection service (SPC). These configurations can be made separately according to actual situation.


2-3

Caution:

After the data configuration, you should use the command write in the previlige mode to save the data into the Flash, so that the data will not be lost in case of power failure or system reboot.

When you use the command reboot to reset the system, if there is still unsaved data in the memory, or the saving is being made, the IAD132E(T) will give you a prompt, in order to ensure that all the configuration data is saved into the Flash.

2.2 Introduction to Networking Application Examples All the configuration examples in this chapter are based on the networking shown in Figure 2-2.

Both the IAD132E(T) 1 and the IAD132E(T) 2 are managed by IAD Management System (IADMS), and register to the IADMS after they start up.

Both the IAD132E(T) 1 and the IAD132E(T) 2 take the local standard for the initial ringing and cadence ringing. In this example, standards in Hong Kong are used.

The upper threshold and lower threshold of the user hooking time take the local standards. In this example, standards in Hong Kong are used.

Current calls will be sustained after the MGC is disconnected from the MG.

2.3 Configuring Basic Data

2.3.1 Tasks for Configuring Basic Data

The basic data describes the physical configuration and features of the IAD132E(T). Table 2-3 shows the tasks in configuring the basic data.

2.3.2 Configuring IP Address

The IP address of the IAD132E(T) refers to the IP address of the internal CPU. It can be configured as:

Fixed IP address Obtained dynamically through the Dynamic Host Configuration Protocol (DHCP)

Server Obtained through PPPoE dialing

The IAD132E(T) needs to acquire the IP address by any of the ways, based on the actual network situation. To change the current IP address obtaining method, run the other IP address obtaining commands. For details, refer to the later part of the document.

Both the uplink network interface and access data user interface of the IAD132E(T) require no configuration of the IP address. All you need to do is to connect the network cables properly.


2-8

Before you have obtained the IP address, you can use the default one of the IAD132E(T), which is: 192.168.100.1.

I. Setting Fixed IP Address for IAD132E(T) 1

In the global configuration mode, run the following command to configure the fixed IP address: ip address ip-address net-mask [gateway-ip].

Example:

set fixed IP address for IAD132E(T) 1.

IAD2000(config)#ip address 210.11.252.19 255.255.255.0

IAD2000(config)#show ip address

--------------------------------------------------

Device network configuration is:

IP address: 210.11.252.19

SubNetwork mask: 255.255.255.0

Default Gateway: 210.11.252.20

--------------------------------------------------

Caution:

After you have set the IP address, you must restart the IAD132E(T) before the IP address can become valid.

The IP address of the IAD132E(T) must be set correctly to ensure normal communications. You should not change the IP address when the IAD132E(T) is working normally.

II. Configuring the IAD132E(T) to Dynamically Obtain IP Address

The IAD132E(T) requires coordination of the Dynamic Host Configuration Protocol (DHCP) server to obtain dynamic IP address. The DHCP server should run normally in the network, and should communicate with the IAD132E(T) smoothly. The command dhcp enable of the IAD132E(T) in the global mode is used to enable the DHCP client program.

Example:

enable DHCP client on IAD132E (T) 1, so that the device can obtain IP address dynamically.

IAD2000(config)#dhcp enable

Reset system is needed if DHCP config changed, continue?[Y|N]:Y


2-9

Note:

After you have enabled the DHCP client program on the IAD132E(T), you should restart the device to make the setting valid.

III. Configuring IAD132E(T) to Obtain IP Address in PPPoE Mode

The IAD132E(T) supports IP network accessing in the PPPoE mode and obtain the IP address through PPPoE dialing. It also supports obtaining the IP address of DNS during PPPoE dialing for DNS resolution.

The configuration of PPPoE involves two steps: configure the username and password, and then enable the use of PPPoE. The system will automatically redial when PPPoE dialing fails due to some network fault.

Example:

set PPPoE username as “zw@isp”, and password as “huawei".

IAD2000(config)#pppoe username zw@isp password huawei

Enable PPPoE dialing.

IAD2000(config)#dhcp enable

Show PPPoE configuration.

IAD2000(config)#show clock

--------------------------------------------------

PPPoE online

PPPoE enable

PPPoE user name: zw@isp

PPPoE password : huawei

--------------------------------------------------

2.3.3 Configuring the Device Information

I. Command Description

Configure the banner

When you log in the IAD132E(T) from the serial port or from a Telnet connection, you will see some welcome messages, including the name of the device, and the contact telephone number. You can set or change these messages with the global config command banner incoming hostname phone.

Example:

set the banner for the IAD132E(T).

IAD2000(config)#banner incoming SZ-NY-CNC-IAD132E(T) 0755-26548888

After you run the command, log in again, and you will see the following:

******************************************

* *

* IAD2000 Integrated Access Device *

* *

******************************************

Copyright(C) 2002-2004 by HUAWEI TECH CO. LTD

Host name: SZ-NY-CNC-IAD132E(T)

Phone: 0755-26548888

Note:

The parameter hostname provides identification for the IAD132E(T) device in a next generation network (NGN). This identification is generally configured according to the requirements of owner of the equipment. If there is no special requirement, the following naming rule is recommended for hostname: “hostname” = “name of the office” + “MG type”. While “name of the office” = “country” + “city” + “location” + “operator name”.

In this example, the hostname “SZ-NY-CNC-IAD132E(T)” indicates an IAD132E(T) device of the operator “CN” in the location of “NY” (Nanyou) in Shenzhen, China.

Enable DNS client on the IAD132E(T)


2-11

After you have enabled the DNS client on the IAD132E(T), the device can access other devices through the domain name, apart from accessing through the IP address. The domain name here of the IAD132E(T) must be identical with that configured with the command if-mg attribute.

Example:

enable the DNS client on the IAD132E(T) 1, specify the domain name as “tele.com”, and the IP address of DNS as 210.11.123.13.

IAD2000(config)#dns domain-name tele.com

IAD2000(config)#dns server 210.11.123.13

Enable SNTP client on the IAD132E(T)

Global synchronization of time is necessary for the generation of logs and accounting records. You can enable SNTP client on the IAD132E(T) for this purpose.

Example:

enable SNTP client on the IAD132E(T) 1, specify the name of the SNTP server as “SNTP-SVR”, time zone as East 8, and synchronization interval as 60 seconds

IAD2000(config)#sntp server name sntp-svr.tele.com

IAD2000(config)#sntp time-zone + 8

IAD2000(config)#sntp interval 60

Caution:

If you want to specify the SNTP server with the name “SNTP-SVR.TELE.COM”, you should first enable the DNS client on the IAD132E(T), then configure the SNTP client. Otherwise, you can only use the IP address 210.11.123.5 to access the SNTP server.

After you have enabled the SNTP client on the IAD132E(T), start time and end time of the log information and accounting information will be subject to the time provided by the SNTP server. In this case, the local time on the IAD132E(T) that is configured with the command clock set hh:mm:ss will not take effect.

Set serial port baud rate

The baud rate of the IAD132E(T) serial port can be changed to adapt to different serial port rates of the maintenance terminal. Use the command baudrate baudrate-value in the privilege mode to set the baud rate.

Example:

set the serial port baud rate of the IAD132E (T) 1 as 115200 bps

IAD2000#baudrate 115200

current serial port baudrate: 115200


2-12

Note:

The serial port baud rate of the IAD132E(T) should be set as identical with that of the maintenance terminal serial port.

The default serial port baud rate of the IAD132E(T) is 9600 bps, and you are not recommended to change it. If you have changed the default baud rate, it will restore to 9600 bps after the device restarts.

Only the root, Oper and Admin can change the serial port baud rate of the IAD132E(T).

Add an IADMS

In a NGN, a huge amount of IADs are running, and it is very difficult for one NMS to manage all of them. So a hierarchical management mode is used, in which a certain number of IADs are managed directly by an IADMS, and multiple IADMSs are managed by the iManager N2000 NMS. An IADMS is a software system running on a workstation.

While configuring the IAD132E(T) for accepting the universal management of IADMS, you must configure the eid (equipment ID) of the IAD132E(T) in IADMS, based on which the IADMS identifies the IAD132(T). The eid of the IAD132(T) must be identical with that on IADMS. After that, other information of the IADMS can be added.

Example:

In the global configuration mode, configure the eid of the IAD132E(T) as “CN23.com”.

IAD2000(config)#eid CN23.com

Adding the IADMS information by using the command iadms in the global mode, and the IP address of the IADMS workstation is 210.11.123.33:

IAD2000(config)#iadms 210.11.123.33 get set trap 162

Set the IAD132E(T) to register to the IADMS when it starts up:

IAD2000(config)#iadms register enable

Note:

When adding an IADMS, you must ensure that the IP address of the IADMS is unique. The command iadms can be used both for adding an IADMS and modifying an IADMS. The character string of a community name is case-sensitive, which means the same character strings

with different cases will be regarded as different community names.

nmsaddress: IP address of IADMS.

getcommunity/setcommunity: Names of the GET/SET communities of the IADMS. The GET/SET community names can be any character string less than 15 characters. A community name is a simple security guarantee mechanism provided by Simple


2-14

Network Management Protocol (SNMP), which is similar to user password. The IAD132E(T) shall decide whether to accept an NM request by comparing the GET/SET community name configured on itself and that configured on the IADMS. By default, the GET community name is “public” and the “SET” community name is “private”, and you can change the community names by yourself.

nmsTrapPort: Trap port number used by the IADMS, which is 162 by default.

enable/disable: Whether the IAD132E(T) is enabled or disabled to register to the IADMS when it starts up.

2.3.4 Configuring the Board


The command board add is used to add a board according to the hardware configuration.

Example:

add the ASI boards for slots 1 and 2 of IAD132E(T) 1.

IAD2000(config)#board add 1 asi

IAD2000(config)#board add 2 asi

Note:

After a board has been added, a fault alarm message will display, showing that the board is abnormal. You do not have to deal with this alarm.

The ASI board can be configured automatically. When the IAD132E(T) is running, if you insert an ASI, the system can identify this board automatically, and configure the basic information for the board. In this case, you do not need to run the command board add to add the ASI. You can also run the command board add to add an ASI board when no ASI board is plugged in the slot.

Boards of other types should be added with the command board add.

2.4 Configuring Interface Data

2.4.1 Tasks for Configuring Interface Data

In NGN networking, the MG is completely separated from the MGC. In Figure 2-2, the IAD132E(T) is the MG, while the softswitch is the MGC. The interface data describes the information concerning the interface and connection between the IAD132E(T) and the MGC.

Table 2-5 shows the task list for configuring the interface data.

Table 2-5 Task list for configuring interface data

4 Start MG interface reset

2.4.2 Add MG Interface


Example:

1) If the MG interface with mgid as 0 does not exist, add this MG interface and enter the interface configuration mode.


2-18

IAD2000(config)#interface mg 0

Are you sure to add MG interface? [Y|N]y


2) If the MG interface with mgid as 6 already exists, enter the MG interface configuration mode.



Note:

When you use the command interface mg mgid, if the interface does not exist, the command will add such an MG interface, and enter the MG interface mode. If the MG interface already exists, you will enter the MG interface mode.

mgid: MG interface identifier with the range of [0, 16777215].

2.4.3 Configuring MG Registration Key


To prevent illegal IAD from registering on MGC, you can enable the MG registration verifying function. You need to configure on the IAD132E(T) and MGC respectively. Use the command mg register-key mgid KeyWord to configure registration key on the IAD132E(T). But this command is available only to the root user.

Example:

Configure the MG with mgid as 0 on the IAD132E(T) 1 as “iad132key” for registering on MGC.

IAD2000(config)#mg register-key aaa


2-19



Configure MG registration key mg register-key BCD-KeyWord Global config mode

Show the MG interface registration key show mg register-key MG interface mode


KeyWord: key, ranging 8–31 characters.

2.4.4 Configuring MG Interface Data


After you have added an MG interface, you should configure data for this interface, otherwise the MG cannot register to the MGC. MG interface data includes: domain name of the MG, transmission port number, MGC IP address, transmission layer port number, type of protocol between MG and MGC, coding type and transmission mode.

To show the IAD registration state, use the show command. show if-mg attribute mgid: This command shows all the MG interface data, interface status and configured MGC parameter of a designated MG interface. show amg all: This command shows some of the MG interface data and interface status of all the MG interfaces.

Example:

configure the interface data for the MG interface with mgid as 0 on the IAD132E (T) 1:

IAD2000(config-if-mg-0)#if-mg attribute port 2427 protocol MGCP code text

port: Port number of the transmission layer protocol. When the MGCP is used, there is only the text format coding type, and the default port number specified in the protocol is 2427.

protocol: Protocol type; IAD132E(T) supports MGCP only.

code: Coding type, which can be text (text coding) or binary (binary coding). The coding type should be negotiated with the MGC, and should be identical with that configured on the MGC. The MGCP only supports text coding.

transfer: Transmission protocol type, which can be Transmission Control Protocol (TCP), User Datagram Protocol (UDP) or Simple Control Transmission Protocol (SCTP). The default is UDP. MGCP only supports UDP.

domain-name: domain name of the MG on which the MG interface is located. It is a character string of 1-60 characters. It must be configured, and be identical with that configured on the MGC.

interface-name: name of the MG interface, which must be configured, and kept identical with that configured on the MGC, defaulted as aaln. This parameter is used only in the MGCP.

mgcip, mgcport: IP address of the MGC, port number of transmission layer protocol, which are subject to the configuration on the MGC. With the MGCP, there is only text coding, and the default port number is 2727.

Caution:

Parameters port, mgcip and mgcport configured on the IAD132E(T) must be the same with those configured on the MGC.

Appendix C lists the data correspondence when the IAD132E(T) interconnects with the SoftXSwitch device.

Before configuring the interface data, configure IP address for the IAD132E(T). For detail, refer to Section “Configuring IP Address”.


2-21

2.4.5 Starting the MG Interface


Before starting the service on the IAD132E(T), you must start the MG interface. The command for starting the MG interface is the same as that for resetting the interface.

Example:

start the MG interface on the IAD132E(T) 1, the mgid is 0.

IAD2000(config-if-mg-0)#reset



Start/reset an MG interface reset MG interface mode

Shut Down MG Interface shutdown MG interface mode

Display MG interface state and parameter show if-mg { all | attribute mgid } User mode


None.

Caution:

After you have added an MG interface, or modified the MG interface data, you must reset this interface to validate the configuration. The purpose to reset the interface is to allow the MG to register again to the MGC.

If you reset an MG interface, the services on the interface will be terminated, so you must use this command with caution.

You can terminate the services on an MG interface by shutting down the interface.


I. Configuration Description

Figure 2-2 shows the networking, while Figure 2-3 and Figure 2-4 show the hardware composition for this example.Table 2-4 and Table 2-2 provide the general information about the data used in the configuration example.

3) Start MG interface IAD132E(T) 1 IAD2000(config-if-mg-0)#reset

IAD132E(T) 2 IAD2000(config-if-mg-0)#reset

2.5 Configuring Access User Data

2.5.1 Introduction to Access Service

The IAD132E(T) provides two types of access services:

Ordinary user service, in which the voice channels are not dedicated but selected randomly. The establishment of a voice channel is controlled by the MGC.

Semi-permanent connection service, in which the voice channels are dedicated and fixed. The establishment of the voice channel is not controlled by the MGC. Instead, it is established by the related commands given from the command line or the NMS.

2.5.2 Configuring Ordinary User Service


The data configuration for ordinary user service is simple and easy. You can just add new users to the ports of the ASIs on the IAD132E(T). Before adding a user, you must configure the basic data and MG interface data (you do not have to start the MG interface until having added the users).


2-23

When adding a user, the data you configure can determine the following information: port number and slot number of the ASI corresponding to the added user, MG identifier, whether layered configuration is made, and terminal identifier terminalid (when no layered configuration is used).

Example:

Configure the access user for IAD132E(T) 1

Add access users to all the ports on slot 1 and slot 2 of the IAD132E(T) 1, and define the ports to be subject to the MG with mgid 0, no layered configuration, the terminalid corresponding to the ports starts from 0. According to the configuration on the MGC, set the VoIP telephone number as 8816172–8816203, internal number as 6172–6203, and support the leave word function.

IAD2000(config-esl-user)#mguser batadd startuser 1/0 enduser 2/15 0 nolayer

0 telno 0 priority 0 leaveword 6172

Note:

After modifying the attributes of the internal numbers, you need to execute the command mguser modify to modify the internal number of the access user to meet the new attributes.

Configure access users of IAD132E(T) 2

Add access users to all the ports on slot 1 of the IAD132E(T) 2, and define the ports to be subject to the MG with mgid 0, no layered configuration, and the terminalid corresponding to the ports starts from 0. According to the configuration on the MGC, set the VoIP telephone number as 6541001–6541016, internal number as 1001–1016. And based on the numbers allocated by the exchange, set PSTN numbers as 8972001–8972016, and support the leave word function.

Note:

The command startservice can restart the service of an individual access user, or restart the services of a batch of users on an MG, or the services of all the access users on an MG. The command endservice can terminate the service of an individual access user, or terminate the services of a batch of users on an MG, or the services of all the access users on an MG.


slotid/portid: slot number/port number. The port number starts from 0, and the port numbers on the ASI (16-analog-subscriber board) ranges from 0 to 15. slotid ranges from 1 to 3.

terminalid: terminal identifier, which corresponds to the port on the ASIs, and are numbered exclusively in the same IAD132E(T). When the layered configuration (layer) is used, the slotid/portid of the MG are “visible” to the MGC. That is to say, the MGC can identify different ports according to the slotid/portid. When the layered configuration is not used (nolayer), the slotid/portid of the MG are “invisible” to the MGC, and you must configure the terminalid, so that the MGC can find the port.

telno: VoIP telephone number. This is the number for the access user, ranging 1–16. It can be a different number from that configured on the MGC, and it is OK if you do not configure this number. The telephone numbers of the user ports on the IAD132E(T) are assigned by the MGC.

mgtelno: internal number of IAD132E(T), ranging 3–8 digits. This number has nothing to do with the telephone number configured on the MGC.

pstntelno: PSTN telephone number. It is the port number of the IAD132E(T) in PSTN when "one set with two numbers” is configured. The number ranges 1–16 digits, and is allocated by the switch in PSTN.


2-25

priorityflag: tag of priority level for the access users, ranging 0–4. This parameter is not used, so there is not need to configure it.

leaveword: whether to support the leave word function of the access user. The value can be 0 or 1, indicating “support” and “no support” respectively. The configuration should be the same with that on the MGC. By default, this function is not supported.

batnum: number of batch process.

Note:

telno and leavewordflag are determined by the configuration on the MGC. pstntelno is determined by the configuration on the switch in PSTN. The configuration on IAD132E(T) is just a record to facilitate management and query.

When batch-adding and batch-deleting the access users, terminalid, telno, pstnno and mgtelno will ascend by one on the basis of the startuser.

Whether to be layered is determined by the configuration on the MGC, you can keep the configuration on the IAD132E(T) identical with that on the MGC.

2.5.3 Configuring SPC Service

Without presence of an MGC, the SPC service supports the issue of commands from the command line terminal or NMS, in order to set up SPC between the ports of two IAD132E(T) devices, or between different ports of the same IAD132E(T) device.

There are two kinds of SPCs: IP SPC and internal SPC. Between the ports of two different IAD132E(T) devices, only IP SPC can be set up. While between two ports of the same IAD132D(T) device, only internal SPC can be set up.

In SPC, the voice channels are fixed and dedicated, so that the service demands and communication quality of important users can be guaranteed.

On the same user port, you can configure either the ordinary access user service or the SPC service. In case both services are configured on the same user port, the SPC service will have a higher priority. To enable the ordinary user service on this port, you must release or delete the SPC service data on this port.


After the basic data has been configured, you can configure the SPC service. The configuration of the SPC service is irrelevant to the configuration state of MG interface data.

Example:

add an internal SPC between slot 1 port 15 and slot 2 port 15 of IAD132E(T) 1, the SPC occupies one voice channel, and the name of the SPC is spcin.


2-26

IAD2000(config)#spc add start 1/15 end 2/15 iad-spc 1 name spcin

Add an IP SPC between slot port 0 of IAD132E(T) 1 and slot port 0 of IAD132E(T) 2, the Real-Time Transport Protocol (RTP) port number of IAD132E(T) 1 is 50000, that of IAD132E(T) 2 is 50120, and the name of the SPC is spcip.

Note:

If an SPC is established successfully, the IAD132E(T) shall return the connection identifier connectid of this SPC. You can use the command show spc slot to show the index number and configuration information of an SPC. You can also use the command show spc {connectid connectid | from fromid } to query the detailed information of the connections start from a specific one, such as the connection id, connection state, connection type and the connection name.

You can release and restore a semi-permanent connection dynamically. The command spc release can release a semi-permanent connection, while the command no spc release can restore a semi-permanent connection. Different from the delete command, the release command releases the connection without deleting the data.


2-27


slotid/portid: slot number/port number. In the configuration commands of SPC, slotid ranges 1–2.

channelnum: the number of port channels of an SPC, currently supporting configuration of 1 in the command after one port channel is established.

spcname: Name of an SPC in a character string of 1–8 characters.

ip-addr: IP address of local IAD132E(T) or remote IAD132E(T).

local-port/remote-port: local/remote Real-Time Transport Protocol (RTP) port number, used to identify different voice channels. Its value is [50000, 50124], and must be a multiple of 4.

connectid: index of a semi-permanent connection.

fromid: start index of an SPC.

endid: end index of an SPC. If you do not input the endid, the last index will be taken by default.

Caution:

If you delete an SPC, its configuration data will get lost. If you enter the fromid of an SPC without inputting the endid, all the SPCs after the fromid will be deleted. So you must use the spc delete command with caution.

When adding an IP SPC, you must configure the DSP channel parameter for the SPC, and the configuration on both ends of the SPC must be the same. The configuration should contain DSP voice code type (dsp-voice-code), echo control enabler (dsp-ece), silence compression enabler (dsp-sce) and RTP packing time interval (dsp-rtppacket-interval).

When configuring IP SPC between IAD132E(T) device A and device B, the local-port configured on device A must be identical with the remote-port on device B, while the remote-port configured on device A must be identical with local-port on device B.

Chapter 3 Advanced Configuration

3.1 Configuring IAD Call Mode

3.1.1 Introduction to Call Mode

I. Call Mode

Call mode refers to the way the IAD132E(T) implements calls.

The IAD132E(T) supports three call modes:

VoIP call mode

By default, the IAD132E(T) uses the VoIP call mode. VoIP calls are implemented under the control of the softswitch in NGN.

Internal call mode

The internal call mode means that IAD132E(T) independently implements the call between two FXS ports without the attendance of softswitch.

PSTN call mode

The PSTN call mode means a networking mode in which the IAD132E(T) is connected to PSTN through the FXO ports. PSTN calls can be classified as AT0 (Analog Trunk) calls, and PSTN calls with and without convergence. The three PSTN call modes cannot be configured simultaneously on the same IAD132E(T).

1) AT0 calls

AT0 calls involve another networking mode for PSTN to interwork with NGN. Refer to Figure 3-1 for reference. PSTN is connected to the FXO port of any IAD132E(T) in the group of IAD132E(T)s through analog trunk cables. Thus, the subscriber of PSTN can send calls to and receive calls from subscribers in the whole group of IAD132E(T)s through the FXO port of this IAD132E(T).

The difference between this networking mode and the trunk media gateway (TMG) is that TMG is connected with NGN and PSTN, while the IAD132E(T) is connected with NGN and PSTN through the analog trunk.

When Subscriber A calls Subscriber B: (Subscriber A must be under the IAD132E(T))

Subscriber A picks up the phone, hears the dialing tone --> dials NGN number D (allocated by media gateway controller (MGC) and configured on the MGC) --> hears the dialing tone sent from PSTN --> dials Subscriber B’s number --> hears the ring back tone—(Subscriber B picks up the phone) --> the call is established.

When Subscriber B calls Subscriber A:

Subscriber B picks up the phone, and hears the dialing tone --> dials PSTN number C (allocated by the exchange configured on the exchange) --> hears the dialing tone sent from NGN --> dials Subscriber A’s number --> hear the ring back tone—(Subscriber A picks up the phone) --> the call is established.

2) Calls with and without convergence

The calls with and without convergence bring the interworking between the subscriber of this IAD132E(T) and the subscriber of PSTN. When the IP network fails, the IAD subscriber can make PSTN calls in these two call modes. Considering the actual


3-3

networking requirement and hardware configuration, you can configure PSTN calls either with or without convergence according to the quantity of FXO ports and FXS ports. If the number of configured FXO ports is less than the number of FXS ports, it is called the PSTN call with convergence; if the number of the configured FXO ports is equal to the number of FXS ports, it is called the PSTN call without convergence.

Figure 3-3 Networking for calls with and without convergence

For the call without convergence, because the number of the configured FXO ports on IAD is equal to the number of FXS ports, two phone numbers (one VoIP number and one PSTN number) can be allocated to each access user of the IAD132E(T). Therefore, this application is called “one phone set with two numbers.”

The flow of calls with and without convergence is illustrated in Figure 3-4.

When Subscriber B calls Subscriber A:


3-4

If Subscriber A is a one-phone-two-number subscriber, Subscriber B needs only to dial Subscriber A’s PSTN number (allocated by the exchange and configured on the exchange).

If Subscriber A is not a one-phone-two-number subscriber, the flow is as follows:

Subscriber B picks up the phone, hears the dialing tone --> dials the PSTN number (to be allocated by the exchange on itself) --> hears the dialing tone sent from the IAD132E(T) --> dials Subscriber A’s inner number --> hears the ring back tone—(Subscriber A picks up the phone) --> the call is established.

II. Call Routing Mode

Call routing mode means how the IAD132E(T) applies the call mode. The IAD132E(T) supports two routing modes:

Ordinary routing mode

Ordinary routing mode means when you hook off, you should first dial a group of specified numbers (prefixes) to select a call mode, then after you hear the two-stage dialing tone, you can dial the called number. The prefix configured for each call mode is only related to the outgoing call, not the incoming call.

Default routing mode

In this mode, you need not dial the prefixes, but dial the called number directly to make the call. The default routing mode is only related to the outgoing call, not the incoming call. The default routing mode of the system is VoIP.

3.1.2 Configuring Call Mode


Configure call mode for IAD

It is possible to configure VoIP mode, internal call mode, and PSTN call mode on the same IAD132E(T) simultaneously. However, only one of the three PSTN call modes can be configured.

For ordinary routing mode calls, a prefix must be configured. The access user must first dial the prefix. When the access user hears the two-stage dialing tone, he/she can dial the called number.

Example:

For calls between the subscribers connected to the IAD132E(T) and those connected to other IADs, the VoIP call mode is adopted, which is configured as the default routing mode. For calls between the subscribers connected to one IAD132E(T), the internal call mode is adopted, for which the prefix is configured as 1. The IAD132E(T) is connected with PSTN through the ATU board (providing four FXO ports). And the PSTN call mode with convergence is configured for calls between IAD and PSTN subscribers. The call prefix is configured as 3.


3-5

IAD2000(config)#call-mode voip default

IAD2000(config)#call-mode internal 1

IAD2000(config)#call-mode pstn convergent 3

Change the call routing mode

To change the call routing mode, clear the current routing mode, and then configure the new routing mode.

Example:

Change the default routing mode from internal routing mode to VoIP routing mode.

IAD2000(config)#no call-mode internal

IAD2000(config)#call-mode voip default

Configure the attributes of the internal phone number

By default, the attribute of internal telephone numbers is configured as: Prefix can be any number with the length of four digits. The internal call of the IAD132E(T) adopts the default configuration of internal telephone number. You can modify the prefix and length of the internal number according to actual needs.

Example:

Change the prefix of the IAD inner number to “99” and the length of it to 5 digits.

IAD2000(config)#inner-number prefix 99 length 5

Configure the PSTN call with convergence

Example:

The IAD132E(T) is connected to PSTN through the ATU board (providing four FXO ports). Configure the ASI board in slots 1 and 2 for accessing 32 voice users. The PSTN call mode with convergence is configured to communicate with the PSTN user, with the convergence ratio being 4:32 and the call prefix as 3.

IAD2000(config)#call-mode pstn convergent 3

Add access users to all the ports on slot 1 and slot 2 of the IAD132E(T), and define the ports to be subject to the MG with mgid 0, no layered configuration, and the terminalid corresponding to the ports starts from 0. Do the following setting according to the configuration on the MGC: Set the VoIP telephone numbers ranging from 2215100 to 2215131, and inner numbers ranging from 5100 to 5131, and support the voice message function.



Note:

The IAD132E(T) internal phone numbers need to be configured only when the internal call mode or the PSTN call mode with convergence is configured.


3-6

Configure the PSTN call mode without convergence

Example:

Connect the IAD132E(T) to PSTN through the ATI board in slot 2 (providing 16 FXO ports), and configure slot 1 with the ASI board for accessing 16 voice users. Configure the system to the PSTN call mode without convergence, with the convergence ratio being 16:16 and the call prefix as 2.

IAD2000(config)#call-mode pstn non-convergent 2

Add access users to all the ports on slot 1 of the IAD132E(T), and define the ports to be subject to the MG with mgid 0, no layered configuration, and the terminalid corresponding to the ports starts from 0. According to the configuration on the MGC, set the VoIP telephone number as 6541001–6541016, internal number as 1001–1016. Based on the numbers allocated by the exchange, configure the PSTN numbers on IAD from 8972001 to 8972016, and support the voice message function.



For the IAD132E(T) with the one-phone-two-number function, the corresponding relation between FXO ports and FXS ports must also be configured.

IAD2000(config)#fxo-fxs start fxo 2/0 fxs 1/0 end fxo 2/15 fxs 1/15

Note:

While configuring the corresponding relation between FXO ports and FXS ports with the command fxo-fxs, make sure that the number of FXO ports is the same as that of FXS ports.

Configure the AT0 call

Example:

The IAD132E(T) is connected to PSTN through the ATI board (providing the 16 FXO ports) in slot 2. Configure the mode as AT0 call mode.

IAD2000(config)#call-mode pstn at0

Add FXO ports to slot 2 of the IAD132E(T). Define the ports to be subject to the MG with mgid 0, adopt no layered configuration, and set the terminalid corresponding to the ports as start from 0. Do the following setting according to the configuration on the MGC: set the VoIP phone numbers ranging from 2215100 to 2215115, and inner numbers ranging from 5100 to 5115, and support the voice message function.

ins-prefix: inserted number, ranging 1–10 digits.

in-prefix: prefix of internal number, ranging 1–3 digits.

3.1.3 Processing Call Collision and Call Waiting

The IAD132E(T) can be configured with call modes (internal call mode and PSTN call mode) beyond the control of the softswitch. So it is possible that there is collision between these call modes and the VoIP call mode which is under the control of the softswitch.

To handle the collision, the command call-conflict start can be used to send the message to the softswitch that the access user has been out of service when the user is


3-8

in the internal call mode or PSTN call mode. If so, when another user calls the access user, the corresponding announcement will be played.

When the access user ends the internal call or PSTN call, the IAD sends the message to the softswitch that the user has resumed the service.

Call waiting is a service realized by the IAD132E(T) in the PSTN call mode without convergence. When a PSTN subscriber calls a subscriber who is making a VoIP call under the control of the IAD132E(T) or an one-phone-two-number subscriber who is making an internal call, there will be call collision. In such case, the IAD132E(T) will send an incoming call prompt to the callee while the PSTN caller is listening to the normal ring back tone. When the callee hooks on, the IAD132E(T) plays the ringing tone again. The subscriber then picks up the phone to establish the call with the PSTN caller.



Configure call collision call-conflict { start | stop } Global config mode

Display the configuration of call collision show call-conflict User mode

3.1.4 Number Insertion

When the IAD is configured with the call routing mode, the function of “number insertion” can be selected. It is to insert some specified numbers before the number the subscriber is calling. With this function, the call routing mode will be more flexible and convenient for the subscriber.

For example, if the first two numbers of an internal call under the control of the IAD is “10”, this internal call can be configured to the call routing mode with the prefix being “1” which is inserted automatically. In this way, a subscriber can directly dial the internal number “10XX” to make a call to the callee even under the common routing mode. The principle is that when the IAD receives the prefix “1”, it will regard the call as in the internal routing mode and discard the prefix “1”. It will also automatically insert “1” before the number which is subsequently dialed. This “1” makes up for the “1” discarded, and the subscriber can directly dial the internal number, without listening to the two-stage dialing tone and repeatedly dialing the prefix “1”.

IAD2000(config)#inner-number prefix 10 length 4

IAD2000(config)#call-mode internal 1 insert 1

3.2 Configuring Software Parameters The IAD provides the function of dynamic querying and configuring software parameters. This makes it possible to control the configurations and software flows by


3-9

configuring the software parameters, so as to adjust to various application statuses. The software parameters of the IAD are classified into system software parameters and MG interface software parameters.

The system software parameters can be configured to adjust the noise, echo, jitter, and loudness of voice, the transmission mode of Fax/Modem, and the type of the MGC which networks with the IAD.

3.2.1 Configuring System Software Parameters


Example:

Configure input/output gain of the voice pinch board DSP.

IAD2000(config)#mg system-parameter 3 3


This command can be used to adjust the volume, but the effect is not as prominent as adjusting the receive/send gain of the PSTN physical port.

Example:

The parameter 8 of the command mg system-parameter controls whether the echo cancellation (EC) switch of the IAD132E(T) is on. By default, the switch is on.

It is recommended that the EC switches at both gateways be on, since this will bring EC at the IAD132E(T) and the PSTN sides into effect. The EC at the IAD132E(T) is controlled by the softswitch. If there is no command sent from the softswitch, the IAD132E(T) takes the default configuration of EC.


Modify the echo return loss to 3 dB, the network level attenuation to 6 dB.

IAD2000(config)#ec set erl 2 yloss

Note:

All the EC parameters have their default values. Normally the default values can be taken. The command no ec set can be used to bring all EC configurations to the default values.

Example:

The voice jitter and information loss have much relevance to the delay jitter of the carrier network and the jitter buffer of the gateway. Currently, the value of jitter buffer is 100 ms by default. What deserves attention is that the adjustment of this parameter has double effects. To increase its value, the capability of jitter removal is enhanced, while


3-10

on the other hand the end-to-end delay is lengthened. Therefore, this parameter should be configured according to different network conditions.

Example:

Configure jitter buffer at all ports to 40 ms.


Example:

Configure the DSP to use A law for voice signal compression.

IAD2000(config)#system set aulaw 0

Modify DSP parameter must reboot the system, continue? [Y|N]:

Caution:

You have to reboot the system to validate modification of the mode for voice signal compression.

Example:

Configure the upper and lower limits for the access user to press hookflash to the local standards, for instance, Hong Kong standard (700 ms for the upper limit and 100 ms for the lower limit).

Name: the name of the system parameter, ranging 0–26. Each digit represents a specific parameter, as listed below:

0: Maximum number of subscribers that can be powered by the remote power supply.


3-11

1: the lower limit for pressing hookflash, being 100 ms in both mainland China and Hong Kong. The default value is 100 ms.

2: the upper limit for pressing hookflash, being 300 ms in mainland China and 700 ms in Hong Kong. The default value is 300 ms.

3: the input gain of the DSP chip, used to adjust the volume. The more the gain is, the higher the volume will be, and conversely. It ranges 2–64, corresponding to -31 dB–0 dB, and the default value is 48 dB.

4. the output gain of the DSP chip, used to adjust the volume. The more the gain is, the higher the volume will be. It ranges 2–64, corresponding to -31 dB – 0 dB, and the default value is 64 dB.

5: the value of jitter buffer, used to adjust this value at all ports. If this value at a certain physical port is adjusted by the command pstnport attribute set, it is not subject to this parameter. When the network is in good condition, it is recommended to set this value to 40 ms. With such configuration, there is little delay in the voice channel and the call completion rate of the Fax and Modem is not affected. This enhances the quality of voice. When the network is in bad condition, it is recommended to set this value to 100 ms and set this value at the fax and modem ports to 60 ms separately. This value ranges 0 ms – 150 ms and the default value is 60 ms.

6: the announcement playing mode for incoming call. If it is set to 0, the MGC plays the announcement; set to 1, the IAD does. The default value is 1.

7: the default coding mode of the DSP channel, ranging 0–20. The value of 0 indicates G.711µ; 4 G.723High; 8 G.711A; 18 G.729; 20 G.723Low. The default value is 8 (G.711A).

8: the default EC switch of the DSP channel, ranging 0–1. The value of 0 indicates the switch is off; 1 on. The default value is 1.

9: the default silence compression switch of the DSP channel. The value of 0 indicates the switch is off; 1 on. The default value is 1.

3.2.2 Configuring MG Interface Software Parameters


Example:

Hold the current calls when the communication between the MGC and the MG is interrupted.

IAD2000(config)#mg interface-parameter 0 1 0

III. Parameter description

mgid: the flag for MG interface, ranging 0–16,777,215.

name: the name of the software parameter, ranging 0–5, whose meanings are listed below:

Parameter 0: It controls whether the ID of the terminal connected to the MG interface adopts layered configuration, ranging 0–1. The value of 0 indicates yes; 1 no. The default value is 1.

Parameter 1: It controls whether the current calls are held when the communication between the MGC and the MG is interrupted, ranging 0–1. The value of 0 indicates yes; 1 no. The default value is 1.

value: the value of the software parameter, corresponding to 0 or 1 in the above description.

3.3 Configuring Standby MGC The IAD132E(T) supports the MGC backup. When the active MGC is faulty, the IAD132E(T) will register on the standby MGC automatically by the heartbeat detection or transaction reliability mechanism. Normally, it can also be manually switched to the standby MGC by the command line.

Before configuring the standby MGC, you have to use the command mg interface-parameter to switch on the MGC backup switch, which is off by default.


3-15

Example:

Switch on the dual homing switch, configure the standby MGC and set its IP address to 210.11.180.19.

IAD2000(config)#mg interface-parameter 0 2 0


IAD2000(config-if-mg-0)#mg backup-mgc 210.11.180.19

Example:

Display the MGC.

IAD2000(config-if-mg-0)#show mgc

mgcport1:2727 mgcip/dnsname1:210.11.180.10

mgcport2:2727 mgcip/dnsname2:210.11.180.19



Configure the standby MGC mg backup-mgc mgcip mgcip [ mgcport mgcport ] MG interface mode

Delete the standby MGC no mg backup-mgc mgcip mgcip [ mgcport mgcport ] MG interface mode

Display the MGC show mgc MG interface mode

Switch the MGC manually mgc switch MG interface mode

mgcip: the IP address or the domain name of the standby MGC. It must be consistent with that actually configured to the standby MGC. The domain name is a character string of 1–60 characters.

mgcport: the port number of transmission layer protocol. With MGCP, only text coding is supported and the default port number is 2727.

3.4 Configuring Common Attributes of Access User The common attributes of access users include: ringing and PSTN port attributes. These attributes can be defined or take the default values.

3.4.1 Configuring Ringing Mapping Record


During the interaction of the MGC and the IAD132E(T), they negotiates about the ringing type. Ringing mapping is to establish a corresponding relationship between the ringing type parameters that the MGC sends to the IAD132E(T) and the ringing tones that the IAD132E(T) provides.

Example:


3-16

Add the ringing mapping records to Hong Kong of mapping the ringing type parameter 22 of the MGC to the ringing tones of the IAD132E(T). Map the cadence ringing tone to the Hong Kong ringing tone type 2 and the initial ringing tone to type 18. With such configuration, when the MGC sends the ringing type parameter 22 to the IAD132E(T), the IADE(T) will adopt these two ringing tones.

IAD2000(config-if-mg-0)#mgringmode add 22 2 18





Add a ringing mapping record mgringmode add mgcpara cadence initialring MG interface mode

Delete a ringing mapping record mgringmode delete [mgcpara ] MG interface mode

Modify the attributes of a ringing mapping record

mgringmode modify mgcpara [cadencering cadenc | initialring initialring ]

MG interface mode

Query the attributes of a ringing mapping record

show mgringmode attribute [mgcpara] User mode


mgcpara: the parameter identifier of the opposite end, ranging 0–255.

cadence: the type of cadence ringing, ranging 0–255. The default value is 0, that is, to adopt the normal ringing tone.

initialring: the type of initial ringing, ranging 0–255. The default value is 4, that is, to adopt the normal ringing tone.

Note:

The data packet that the MGC sends to the IAD132E(T) contains the ringing type parameter (whose value is the same as that of mgcpara), by which the IAD132E(T) searches in the table of ringing mapping records, finds the matching mgcpara and then gets the corresponding ringing types of cadencering and initialring.

3.4.2 Configuring PSTN Port Attribute

The PSTN port attributes include: the volume which can be sent and received by the PSTN access user, whether pulse dialing is permitted at the PSTN port, and whether to provide polarity reversal charging at the PSTN port.


3-17

I. Configuring Polarity Reversal Charging

Polarity reversal charging is a way to realize “immediate charging” of the access user. The charging terminal (for example, user charging phone) with this function has charging data itself, so only the start and end time of the conversation is needed. The IAD132E(T) identifies the start and end time of the conversation by the polarity reversal of the subscriber line to which the ASI board is connected, and in this way it realizes polarity reversal charging.

If the IAD132E(T) coordinates with the MGC to send the polarity reversal signal, either the IAD or the MGC can be configured to control the polarity reversal signal. However, it is recommended to select the MGC, that is, to set system parameter 21 of the IAD to 0 and set the polarity reversal at the subscriber port to “normal”. Surely, the IAD can also be selected according to the actual condition.

Caution:

When the IAD is set to control the polarity reversal charging signal, the subscriber polarity reversal parameter of the MGC must be set to “no”. Otherwise, there will be repeated charging.

If the IAD is set to control polarity reversal charging, the PSTN port has to be configured with polarity reversal charging as well as the system parameter 21 that controls the polarity reversal charging signal. To modify a system parameter, use the command mg system-parameter.

Example:

Configure the attributes of port 0 of slot 1. To set the gain type of the PSTN access user to 6 and to enable pulse dialing and polarity reversal charging at the PSTN port.

IAD2000(config-esl-user)#pstnport attribute set 1/0 6 enable reverse

Example:

Set the IAD to control the polarity reversal signal, use the following command. To make this successful, it must be ensured that the polarity reversal switch on the MGC is off.


II. Configuring the Send and Receive Gain at the PSTN Physical Port

Normally the volume of the talk can be greatly enhanced by adjusting the send and receive gain at the PSTN physical port of the IAD132E(T).

As recommended in the Chinese national standards, the send and receive gain of the local network is 0/-3.5 (that is, high gain) and that of the toll network is 0/-7. In contrast, it is recommended in the foreign countries that the send and receive gain of


3-18

narrowband transmission is both 0/-7. Because the voice of the IAD132E(T) is sent and received by RTP packets, which can be regarded as a group trunk, similar to the PCM trunk, it is recommended to set the send and receive gain of the subscriber physical port of the IAD132E(T) to 0/-7 (that is, low gain).

Example:

Set the send and receive gain at port 0 of slot 1 to low gain.

IAD2000(config-esl-user)#pstnport attribute set 1/0 1 disable reverse

IV. Parameter Description

slotid/portid: slotid is the number of the slot, ranging 1–2; portid is the port number of the analog subscriber, ranging 0–15.

voicegain: the gain type of the PSTN access user. The value of this parameter represents the voice volume sent and received at the PSTN port. The more the gain is, the louder the voice will be The gain is calculated in dB. The sum of the send and receive gain ranges 0–17 and the default value is 7.

pulse-dial: to set whether to enable pulse dialing at the PSTN port. The two values are “enable” and “disable”, and the default value is “disable”.

Pole: to set whether to support polarity reversal charging at the PSTN port. The two values are “normal” and “reversal”, and the default value is “normal”.

V21TimerLen: the duration set at the timer, being 10 seconds by default. Once the PSTN port detects out the 2100-Hz polarity reversal signal, it will start a timer. If the timer does not detect out the V21 signal within the preset duration, it will regard the signal as a modem signal; otherwise, it will regard the signal as a FAX signal.

3.5 Configuring Parameters of Built-In LAN Switch

3.5.1 Description of Built-In LAN Switch Port

The chip of the built-in LAN Switch in the IAD132E(T) accommodates six ports, among which ports 1–4 are the four Ethernet ports at the front panel, port 5 is for internal use and port 6 is fixed to the upstream Ethernet port of slot 3. Ports 1–4 and 6 do not have MAC addresses, nor are they configured with IP addresses. They can be used by merely being connected to the Ethernet cable. The “Ethernet ports” hereinafter refer to the external ports (ports 1, 2, 3, 4, and 6) provided by the LAN Switch chip if there is no special treatment.

The functions of the LAN Switch ports are listed below:

Being upstream ports of the IAD132E(T).

Port 6 can only be used as an upstream port. Ports 1–4 can be used as both upstream ports and data access ports (downstream ports)

Accessing data subscribers.


3-20

Ports 1–4, except the one used as an upstream port, can be used to access data subscribers.

Installing the IAD132E(T) in a stack through an Ethernet port.

Figure 3-5 shows the stack installation of multiple IAD132E(T). These IAD132E(T)s are stacked and then connected to the upstream equipment (normally a router or a switch in the IP network) through an Ethernet port. This saves the port resources for the upstream network equipment.

In the above figure, the six IAD132E(T)s are installed in a stack. The (2), (3), and (4) are connected to the (1) directly, while the (5) and (6) are connected to the (1) indirectly. The services of all the six are transferred to the upstream network equipment through the Ethernet port of the (1). The IAD132E(T) supports multi-level stack.

3.5.2 Configuring Precedence of Voice Packets Forwarding

I. Principle

There are data packets and voice packets transferred to the upstream equipment through the IAD132E(T). To ensure high quality of voice and to give precedence to voice packets, the voice packets must be separated from the data packets. The specific way is as follows: Configure VLAN Tag and rather high precedence to voice packets on the IAD, and the packets will be separated at the upper network equipment (for instance, the LAN Switch).

As shown in Figure 3-6, the IAD132E(T) is connected to the upper network equipment through only one upstream port. When the voice packets are configured with VLAN Tag and rather high precedence on the IAD, the LAN Switch A will forward the voice packets with the VLAN Tag to the LAN Switch C through a special interface (“tag” in the figure)


3-21

and forward the voice packets without the VLAN Tag to the LAN Switch B through another interface (“distag” in the figure). In this way, the separation of voice and data packets is realized at the LAN Switch A.

Due to the rather high precedence configured to voice packets, the LAN Switch A will discard some data packets and forward the voice packets to the LAN Switch C when the network is blocked.

IAD132E(T)

IP netw ork

tag distag

Figure 3-6 Networking diagram for separating voice packets

On the IAD132E(T), only voice packets can be configured with VLAN Tag and precedence. This is due to the flow direction of packets in the IAD. In Figure 3-7, ports 1, 2, 3, 4, and 6 are the external ports provided by the LAN Switch chip. Port 1 is used for upstream transmission, and ports 2, 3, 4, and 6 are used to access subscribers. Port 5 is for internal use of the chip.

The CPU achieves configuration of VLAN Tag and precedence to voice packets. The upstream voice stream is first coded at the DSP, then transformed into voice packets at the CPU, and finally transmitted to the IP network through port 1 of the LAN Switch chip. In contrast, the upstream data stream is accessed through ports 2, 3, 4, and 6, then transmitted to the IP network through port 1, without being processed at the CPU. Therefore, only voice packets can be configured with VLAN Tag and precedence.

II. Command Description

Example:

Enable the VLAN Tag function on the IAD132E(T), and configure VLAN Tag to the upstream voice packets by setting Tag to 0 and precedence to 3.

IAD2000(config)#tag enable

Change the VLAN tag configuration will interrupt current conversations,

continue?[Y|N]: Y

IAD2000(config)#tag vlanid 0 priority 3

Note:

When the VLAN Tag is used to separate voice and data packets, it must be ensured that the upper network equipment (a router or a LAN Switch) also supports VLAN Tag. When the VLAN Tag function is enabled, the current calls will be affected.

Example:

Set ToS (Type of Service) of the voice packets to the highest reliability, and that of the other packets to the lowest cost.

IAD2000(config)#tos voice priority reliability

IAD2000(config)#tos other priority mincost


3-23

Note:

The configuration of ToS is similar to that of VLAN Tag. Whether the configuration is valid also depends on the upper IP equipment.

3.5.3 Other Configurations of LAN Switch


Example:

Enter LAN Switch mode and shut down port 4.

IAD2000(lanswitch)#shutdown 4

Example:

Open port 4.

IAD2000(lanswitch)#no shutdown 4

Example:

Any port on the front panel of the IAD132E(T) can be used as the port through which the IAD is connected to the IP network, without any other configuration. Slot 3 can be configured with boards FTIU, FSIU or FMIU to function as an upstream port. When voice packets are transmitted to the IP network through these boards, you have to use the command uplink to configure the upstream port. The number of the upstream port is fixed to 6.


Example:

Set port 1 to the full duplex mode.

IAD2000(lanswitch)#duplex full 1

Example:


3-24

Set the baud rate at port 2 to the auto negotiation mode and that at port 3 to 10 Mbit/s.

IAD2000(lanswitch)#negotiation-auto 2

IAD2000(lanswitch)#speed 10 3

Note:

Ports 1–4 of the IAD132E(T) are 10/100Base-TX Ethernet ports, supporting baud rates of both 10 Mbit/s and 100 Mbit/s. They can work in half-duplex, full-duplex and auto negotiation modes. They can also negotiate with other network equipment for the working mode and baud rate, and select the most appropriate automatically. The default working mode is the auto negotiation mode.

Example:

Set port 2 with flow control and port 3 without.

IAD2000(lanswitch)#flow-control 2

IAD2000(lanswitch)#no flow-control 3

3.6 Configuring Charging Machine The charging terminal connected to the IAD132E(T) can be a console or a charging machine. This part introduces the configuration of the charging machine. The IAD132E(T) sends the charging information of each subscriber port to the charging machine in real time, and the charging machine calculates the call fees.

The IAD132E(T) is connected to the charging machine through a baud rate of 9,600 bit/s, with the maximum of secure transmission distance being 15 meters.

3.7 Configuring MGCP Parameters You can define the MGCP parameters or just adopt the default values for them. It is recommended to adopt the default values. If you are to modify these parameters, be sure to operate in the global config mode.

Example:

Set the maximum of retransmission duration to 20 seconds and to disable the at_most_once function.

IAD2000(config)#mgcp maxRetranTimer 20 AtMostOnceFlag false



Configure MGCP parameters

mgcp { AtMostOnceFlag AtMostOnceFlag | AtMostOnceTimer AtMostOnceTimer | MaxRetranTimer MaxRetranTimer | ProvRspDelay ProvRspDelay | ProvRspFlag ProvRspFlag | ProvRspTimer ProvRspTimer | RetranTimerSeedFlag RetranTimerSeedFlag | RetranTimerSeed RetranTimerSeed | RetranDisconnectThreshold RetranDisconnectThreshold | RetranSuspicionThreshold RetranSuspicionThreshold }

Global config mode

Display the MGCP version and parameters

show mgcp {ver | param} User mode

AtMostOnceFlag: to set whether to enable the at_most_once function. This function means that when A receives a command, it execute it only once. In this way, such case can be avoided that A re-sends the packets to B when the response from B is being transmitted in the network, that is, a command is re-executed. The values can be “TRUE” or “FALSE”, and the default value is “TRUE”.

AtMostOnceTimer: the duration set at the timer for the at_most_once function. B calculates the time from the point when it sends the response message. If it receives the sent again packets within the duration set for this parameter, it will discard them. The value cannot be larger than 60 seconds and the default value is 30 seconds.

MaxRetranTimer: the maximum of retransmission time. If a command is sent, but no response is received, the command will be re-sent. The command will not be re-sent if no response is received within the duration set for this parameter.

RetranTimerSeedFlag: to set whether to configure the retransmission algorithm initial seed value. The two choices are “TRUE” and “FALSE”. If it is set to “TRUE”, it indicates that the first retransmission duration is set to RetranTimerSeed; or else, it is fixed to 2 seconds.


3-29

RetranTimerSeed: the initial seed value of the retransmission algorithm. It cannot be larger than 30 seconds, and must work in coordination with the RetranTimerSeedFlag.

RetranSuspicionThreshold: the retransmission suspicion threshold. It must be smaller than RetranDisconnectThreshold. If the times for re-sending a command exceeds this value, the system enters the suspicion status and checks the DNS address or tries other destination addresses.

RetranDisconnectThreshold: the retransmission disconnect threshold. It must be larger than the RetranSuspicionThreshold. When a system enters the suspicion status, if the times for re-sending a command exceeds this value, the command will not be sent again again.

ProvRspFlag: to set whether to send a temporary response. When A sends a command to B, if the command execution takes a long time, B will send a temporary response to A, confirming that it has received the command. This reduces the possibility for A to resend the command. The two values are “TRUE” and ”FALSE”, and the default value is “TRUE”.

ProvRspTimer: the duration set for the temporary response, from the point when B receives A’s command to the point when it sends the temporary response. This value cannot be larger than 5 seconds, and the default value is 2 seconds.

ProvRspDelay: the duration set for the temporary response delay. When A receives the temporary response, it prolongs the MaxRetranTimer by a duration of ProvRspDelay. This value must be larger than 30 seconds, and the default value is 5 seconds.

Note:

All the above parameters are optional. When a parameter is not checked, it means to adopt the default value. It is recommended to modify these parameters with caution. Either A or B can be MGC or IAD132E(T).

Operation Manual U-SYS IAD132E(T) Integrated Access Device Chapter 4 Maintenance Operations

4-1

Chapter 4 Maintenance Operations

To ensure normal operation of IAD132E(T), you should carry out routine maintenance after the data has been configured correctly. This chapter introduces the common operations in daily maintenance, including: system management, access service management, operator management, log management, alarm management and use of network tools.

4.1 System Management

4.1.1 Saving and Backing up the Data

To ensure system reliability and data security, IAD132E(T) supports the saving of data and backup of program and data. Table 4-1 shows the different aspects of saving and backing up operations.

Table 4-1 Saving and backuing up the data

Item Save Backup

Data source SDRAM (CVP) Flash memory on the mother board

Destination Flash (CVP) Network PC or terminal

Managed contents Data

data

running-config

startup-config

I. Saving the data

The system data will be saved into the SDRAM of the CVP after configuration. To prevent loss of data caused by unexpected events, you should save the configured data into the Flash memory. There are two methods to save the data: auto-save and manual-save.

Auto-save 1) Show the auto-save settings.

Execute the command show data autosave setting to display the auto-save settings for system configuration data.


4-2

For example: show the current auto-save setting.

IAD2000>show data autosave setting

-------------------------------------------------------------------

System autosave switch: off autosave interval: 3600 minutes

-------------------------------------------------------------------

2) Set the auto-save switch.

Execute the command data set autosave {on|off} to set the auto-save switch for the configuration data. If you select on, the data will be saved at the set time interval. If you select off, the system will not save the data automatically, and you should save the data by yourself.

For example: turn on the auto-save switch.

IAD2000(config)#data set autosave on

-------------------------------------------------------------------

System autosave switch: on autosave interval: 3600 minutes

-------------------------------------------------------------------

3) Set the auto-save time interval for system configuration data.

By default, auto-save is made once every 3600 minutes. You can use the command data set autosave interval time_value to set the time interval in minute for the saving.

For example: set the auto-save time interval as 120 minutes.

IAD2000(config)#data set autosave interval 120

-------------------------------------------------------------------

System autosave switch: on autosave interval: 120 minutes

-------------------------------------------------------------------

Caution:

Too frequent saving of data will affect the system performance, so you are recommended to set the auto-save time interval to be longer than one hour.

Manual-save 1) Show the unsaved data percentage.

You can use the command show data unsaved percent to show the percentage of unsaved configuration data.

For example:

IAD2000> show data unsaved percent


4-3

-------------------------------------------------------------------

Now, the percentage of unsaved configuration data on slot 0 main control

board is: 10%

-------------------------------------------------------------------

If you have made new configuration, you can also save the data directly.

2) Save data manually

If there is unsaved data in the system, you can execute the command write in the privileged mode to save the data. When the write command is running, the data saving progress will be displayed.

Note:

You can use the write command to save the configuration data immediately, no matter whether the auto-save function has been enabled or not.

II. Backing up the data

You can back up the database file of IAD132E(T) to a designated computer, so that you can restore IAD132E(T) if it fails. You can also back up the database file to local computer after you have made the configuration on one IAD132E(T) device, then use the configuration file on another IAD132E(T) device after necessary modification, in order to save your configuration effort.

The command to back up system data is backup data { xmodem | ftp ip filename | tftp ip filename}.

When you execute the backup command, you must specify the protocol used for the backup.

The backup can be implemented either through the serial port, or the network port for maintenance. If it is through the serial port, XModem shall be used. If it is through the network port, File Transfer Protocol (FTP) or Trivial File Transfer Protocol (TFTP) shall be used.

If you back up the data through the network port, you should specify the IP address of the FTP Server or TFTP Server, and you should start the FTP Server or TFTP Server program on the PC. Since TFTP does not support directory function, you should create a directory on the TFTP server to store the backup file.

If you back up the data through the serial port, you should use the file receiving function of HyperTerminal to receive the file, and set the directory on the HyperTerminal to store the backup file. The file receiving protocol is XModem.


4-4

For example: use TFTP to back up the database file through the network port to the PC with IP address of 10.11.116.25.

1) Make sure the PC that runs TFTP program is well connected with IAD132E(T).

If the default directory is not the expected one to store the backup file, click <Settings> to designate the directory, then click <OK> to confirm. Refer to U-SYS IAD132E(T) Integrated Access Device Installation Manual for the configuration method of TFTP.

2) Input the following command on the command line terminal to back up the data: IAD2000#backup data tftp 10.11.116.25 cfg.dat

3) If the parameter you input is incorrect, or the TFTP connection is not normal, error prompts will appear, and you should check the reason according to the prompt. If everything goes alright, prompt message will appear after the backup is finished,

In the backup process, you can execute the command show progress backup to display the progress.

4.1.2 Rebooting the System

In the privileged mode, execute the command reboot to restart the system. Before rebooting the system, you must execute the command write to save the data.

4.1.3 Showing the CPU Occupation Ratio

In the user mode, execute the command show cpu to display the CPU occupation ratio. If the CPU occupation ratio is higher than 80%, it means the CPU is overloaded. It is recommended to check the overload cause in time.

For example:

IAD2000> show cpu

CPU occupancy: 9%

4.1.4 Showing System Date and Time

In the user mode, execute the command show clock to display the system time of IAD132E(T).

If the system time of IAD132E(T) is incorrect, you can enter the privileged mode and execute the command clock set to set the time. The time should be set like this:

time hh:mm:ss, which means hour: minute: second date yyyy-mm-dd, which means year-month-day

For example: display current system time, and set the time as 30 second, 50 minute, 17 clock of June 28th 2002.

IAD2000> show clock


4-5

Date: 2000-04-26

Time: 12:27:23

IAD2000# clock set 17: 47: 18 2002-07-19

Date: 2002-07-19

Time: 17:47:18

4.1.5 Showing Version Information

I. Showing system software version

In the user mode, you can execute the command show version to display the versions of the Basic Input Output System (BIOS) and the system software.

For example:

IAD2000> show version

Equipment type : IAD132E(T)

SLOT 0 CVP mainboard version information

PCB version : AG11CVP.2

BIOS version : 303

Software version : IAD2000V100R002B01D020

CPLD-A version : 100

CPLD-B version : 102

SLOT 1 ATI interface board version information

PCB version : AG11ATI.1 REV.A

Chip version : 2

SLOT 2 ASIB interface board version information

PCB version : AG11ASI.2 REV.A

Chip version : 19

SLOT 3 ATU interface board version information

PCB version : AG11ATU.1 REV.0

Chip version : 0

II. Showing MGCP version

You can execute the command show mgcp ver to display the version number of the Media Gateway Control Protocol (MGCP).

IAD2000>show mgcp ver

MGCP version: 1

4.1.6 Controlling the Output of Information to Terminals

IAD132E(T) information that can be output to the terminals includes:

syslog (system log information)


4-6

oprlog (system operation log information) debug (system debugging information) alarm (system alarm information) trace (tracing information) diagnose (diagnose information) stat (statistical information) other (other information)

IAD132E(T) maintenance and management terminals include: command line terminal, network management station (NMS), log host and Web NMS.

Information generated on IAD132E(T) is not sent to the various terminals directly. Instead, it is first sent to IAD132E(T) information center, which is a software component that runs on the CVP. This information center controls the output of information to the various terminals, like which type of information, and what level of the information, should a terminal receive.

The control of information output to the terminals includes the setting of terminal output switch for the terminals, and the output information level.

I. Setting the information output switch

By setting the information output switch, you can control the type of information to be output to a certain terminal. The commands are shown in Table 4-2.



Set the information output switch for the CLI infoswitch cli Global config

Set the information output switch for the NMS infoswitch nms Global config

Set the information output switch for the Log host infoswitch syslog Global config

Set the information output switch for the Web NMS infoswitch www Global config

Display the information output switch for the CLI show infoswitch cli User

Display the information output switch for the NMS show infoswitch nms User

Display the information output switch for the Log host show infoswitch syslog User

Display the information output switch for the Web NMS show infoswitch www User


4-7

Note:

When setting the CLI information output switch and level, the Client ID, which can be obtained through command show client, should be input to show the CLI client end information of the operator, including the client ID, user name, IP address and logon time. Multiple types of information output switches can be set for the same terminal at the same time. There are two switches to control the output of alarm information to the CLI terminal. Switch 1: use the command infoswitch cli to set whether to report the alarm information to the CLI terminal. Switch 2: use the command (no) alarm output to set whether to report alarm information to the CLI terminal according to preset conditions. Refer to 4.5.6 for the use of switch 2.

For example: set not to send the system log to NMS SZ-ABC-WS_1, and send the alarm information, debugging information, diagnose information to the CLI terminal named “bbb”:

IAD2000(config)#infoswitch nms SZ-ABC-WS_1 syslog off

IAD2000> show client

------------------------------------------------------------------


------------------------------------------------------------------

1 -- 0. 0. 0. 0

2 aaa 10. 20. 50. 40 2003- 3-29 11:11:20

3 system 10. 20. 50. 45 2003- 3-29 11:11:30

4 bbb 10. 21.200.250 2003- 3-29 11:15:14

------------------------------------------------------------------

According to the Client Name, you can get the Client ID of "bbb", which is 4. Then set the information output switch according to the Client ID.

IAD2000(config)#infoswitch cli 4 alarm on debug on diagnose on

Note:

Operator who maintains the system through the serial port has a fixed Client ID of 1, and the IP address displays as 0.0.0.0. In the example, the Client Name is “---”, which means there is no login on the serial port at present. The naming method of NMS is similar with that of the IAD device.


4-8

II. Setting the information output level

By setting the information output switch, you can control the level of information to be output to a certain terminal, as shown in Table 4-3.



Set the information output level for the CLI infolevel cli Global config

Set the information output level for the NMS infolevel nms Global config

Set the information output level for the Log host infolevel syslog Global config

Set the information output level for the Web NMS infolevel www Global config

Display the information output level for the CLI show infoswitch cli User

Display the information output level for the NMS show infolevel nms User

Display the information output level for the Log host show infolevel syslog User

Display the information output level for the Web NMS show infolevel www User

Note:

The information output switch must be turned on before the output level can take effect. A higher level means the information is more important. After you have set a level, all the information above this level will be output. The default output level is 0, which means all the information will be output. Levels of multiple types of information that is output to the same terminal can be set in one time.

For example: set the output level of syslog to NMS SZ-ABC-WS_1 as 3, and set the output levels of alarm, debugging and diagnosis information to CLI terminal with Clinet ID 3 to 1, 2 and 3 respectively.

IAD2000(config)# infolevel nms SZ-ABC-WS_1 syslog 3

IAD2000(config)# infolevel cli 3 alarm 1 debug 2 diagnose 3

4.2 Access Service Management

4.2.1 Terminating and Starting the Access Service

I. Ordinary access service

IAD132E(T) can terminate the online subscriber service, or restart the service, in order to facilitate management on the subscribers.


4-9


Force disconnect the service endservice { slotid/portid | mgid mgid terminalid batnum } Privilege

Restart the service startservice { slotid/portid | mgid mgid terminalid batnum } Privilege

batnum: number of batch processes.

II. SPC service

The start or termination of Semi-Permanent Connection (SPC) service is actually the linking or releasing of the SPC. After you have released an SPC, the relevant configuration data is not removed. You can establish the SPC again when necessary.


Release an SPC no spc release { connectid connectid | from-connectid fromid [ to-connectid endid ] } Global config

Establish an SPC spc release{ connectid connectid | from-connectid fromid [ to-connectid endid ] } Global config

4.2.2 Resetting the MG Port

In the privilege mode, use the command reset { slotid/portid | mgid mgid terminalid batnum } to reset the access port.

Caution:

This command should be used with caution. If you reset the access port, the connected services will be interrupted.

4.2.3 Showing Port Status

In the user mode, you can execute the command show port state slotid/portid to display the port status information.


4-10

4.2.4 Showing MG User Data

I. Ordinary access service

In the user mode, you can execute the command show mguser startuser slotid/portid enduser slotid/portid to display the service data of the access users.

II. SPC service

In the user mode, use the command show spc { connectid connectid | from-connectid fromid | slot } to display the service data of the access users.

4.2.5 Sending On-hook Signals to Console

After an IAD subscriber hooks on, the IAD can be configured to send the on-hook signals to the IP console, so as to facilitate the console to charge accurately.



Sending on-hook signal to IP console console ip Global config mode

Canceling the sending of on-hook signal to IP console no console ip Global config mode

The parameter ip is the IP address of the console.

Example:

Configure the IAD to send the on-hook signals to the IP console, of which the IP address is 192.20.129.2.

IAD2000(config)# console 192.20.129.2

4.2.6 Testing Access User

IAD132E(T) supports the diagnosis and test of access user port.

Before testing the port on ASI board, you must first make sure whether the ASI board is in normal running status. Only when it is normal, can you test the port.

If the tested port is in the following status, the operation will fail.

There is SPC service on the port. The port is already in test status. The port status is faulty. The port is in loopback status.


4-11

The port is in busy status and the “if the port is busy test it by force” is not selected.

I. External line test of access user

The object of external line test of access user is the user loop. It tests the performance indexes of user loop (external line), such as capacitance and resistance between lines. Then it compares such data with the standards to judge the condition of the external line, and provide reference for the maintenance of user line.

The test items are as follows.

Insulation resistance between the ground and A line, insulation resistance between the ground and B line, insulation resistance between A line and B line, polarity-reversal resistances of A line and B line, loopback resistances of A line and B line.

Capacitance between the ground and A line, capacitance between the ground and B line, and the capacitance between A line and B line.

DC voltage between the ground and A line, DC voltage between the ground and B line, and the DC voltage between A line and B line.

In privilege mode, you can use command pots loop-line-test { slotid/portid | telno telno } [busy busyflag] to execute external line test of a port on the ASI board.

busyflag: Processing flag when busy. 0: No test when busy. 1: Test by force when busy.

By default, it is set as “no test when busy”.

The ports configured with telephone numbers can be tested through telephone numbers. For those not configured with telephone numbers, you can only test them through physical information (slot number/port number).

Example:

Performing external line test to port 0 on slot 2.

IAD2000#pots loop-line-test 2/0

slot 2 port 0 ( telno - mgid 0 terminalid 1 ) under testing, Please wait......

Test item result

--------------------------------------------------------------

A->ground AC voltage (V) : 0.443

B->ground AC voltage (V) : 0.443

A->B AC voltage (V) : 0.000

A->ground DC voltage (V) : -0.592

B->ground DC voltage (V) : -0.590

A->B DC voltage (V) : -0.002

A->ground insulation resistance (ohm) : > 10M


4-12

B->ground insulation resistance (ohm) : > 10M

A->B insulation resistance (ohm) : > 10M

A->B loop resistance (ohm) : 1.873M

A->B polarity reversal resistance(ohm) : 3.339M

A->ground capacitance (uF) : 0.000

B->ground capacitance (uF) : 0.000

A->B capacitance (uF) : 0.005

Conclusion : phone not connected

--------------------------------------------------------------

In global config mode, you can use command loop-line-threshold set para-name para-value to set the parameters for external line test, while command loop-line-threshold restore to restore the default parameters of external line test.

II. Internal line test of access user

The object of internal line test of access user is the user circuit of ASI board. It tests the functions (such as ringing, battery feed, dialing tone, etc.) and some parameters (such as battery feed voltage, voltage of ringing current) of the user circuit. It tests whether the functions of user circuit can be implemented normally and provides reference for the maintenance of user circuits especially the internal circuits of ASI board. The test items are as follows.

Off-hook function Dialing tone Function of receiving pulse numbers Function of receiving dual tone numbers Ringback tone Busy tone Battery feed function Polarity-reversal function On-hook function Ringing function Intercepting of ringing Voltage of battery feed Voltage of ringing current Current of circuit

In privilege mode, you can execute command pots circuit-test { slotid/portid | telno telno }[busy busyflag] to start the internal line test of a port.

Example:

Performing internal line test to port 0 on slot 2.

IAD2000# pots circuit-test 2/0

Slot 2 port 0 ( telno - mgid 0 terminalid 1 ) under testing, Please wait......


4-13

----------------------------------------------------------

4.3 Operator Management

Operators here indicate those people who maintain and operate on IAD132E(T) through the CLI terminal. IAD132E(T) implements strict identification on the operators: an operator must present correct user name and password to log in, and the operators have different authorities to manage the device.

4.3.1 Operation Task List

Table 4-5 lists the configuration tasks for log operation.

Table 4-5 Log operation task list

S/N Operation Command Mode

1 Add an operator user name Global config

2 Delete an operator no user name Global config

3 Set operator authority level user level Global config

4 Change operator password user password Global config

5 Set operator reenter number user reenter Global config

6 Set operator appendix information user apdinfo Global config

7 Show operator information show terminal user / show client User

8 Disconnect an operator user disconnect clientid Privilege


4-14

4.3.2 Adding/Deleting an Operator

Each operator has an unique user name, and the password can be set by the operator himself. When an operator logs in, and the user name matches the password, the system will check whether the operator has already logged in. If the operator has already logged in at the Console, the system will decide whether to accept or reject the login request according to the configured number of reenters.

I. Operator attributes

User name: a unique character string in the system, which is printable, and ranges from 1 to 15 characters.

Authority: administrator (Admin), operator (Oper) and ordinary (Exec).

The Exec can only make simple queries, and execute some system commands. The Oper can configure the device, such as configuring the access service. The Admin can make all the configurations.

A higher-authority operator can execute the commands of a lower level, while a lower-authority operator cannot execute the commands of a higher level.

Password: a character string of 1 to 15 characters, and must be input correctly. Reenter number: an operator can log in from different terminals at the same time,

and the number of this simultaneous login is decided by the reenter number, which ranges from 0 to 4. 0 means the operator cannot log in. Generally, 1 is recommended.

Appendix information: a string of no more than 35 characters that contains the contact method of the operator, it can also be null.

II. Adding an operator

When adding an operator, you should input the user name, password, authority level and allowed reenter number. The user name cannot repeat with each other, and no space is allowed in a user name.

Only the Root or Admin can add new operators to the system. The Root can add Exec, Oper and Admin to the system, the Admin can add Exec

and Oper to the system. You can add multiple operators in one time, and a maximum of 126 operators

can be added to the system.

For example: add an operator named “abc” with Oper authority, and reenter number is 2:

IAD2000(config)# user name

User Name(<=15chars): abc

User Password(<=15chars):

Confirm Password(<=15chars):


4-15

User's Level(1--3).

1.Exec 2.Oper 3.Admin: 2

Permitted Reenter Number(0--4): 2

This User Is Added!

Continue? [Y|N] n

If you want to add another operator, you should input y here.

III. Deleting an operator

An Admin can delete an operator by using the command no user name, only the user name is needed when deleting this user.

Note:

An operator cannot delete himself. The Admin “system” cannot be deleted. An operator who is logging in cannot be deleted. If you really need to delete this operator, you should first disconnect this operator. A higher-authority operator can use the command user disconnect to reject a logging in Telnet operator who has a lower authority. You can delete multiple operators at one time.

For example: delete the operator “aaa”:

IAD2000(config)# no user name

User's Name(<=15chars): aaa

This user has been deleted!

Continue?[Y|N] n

4.3.3 Setting Operator Authority

Generally, the authority of an operator has already been set when the operator was added to the system. If the authority of a certain operator should be changed, an Admin or an opertor with higher authority can do the job. The superadministrator “root” can change the authorities of all the operators, and Admin can change the authorities of the Oper and Exec, but cannot change that of himself or other Admins. The Oper and Exec cannot change the authority of themselves.

For example: change the authority of “aaa” from Exec to Oper:

IAD2000(config)# user level

User Name(<=15chars): aaa

1.Exec 2.Oper 3.Admin:

User's Level(1--3). 2


4-16

Confirm Level(1--3): 2

Changed ok!

Continue?[Y|N] n

4.3.4 Changing Operator Password

The superadmin “root” and an Admin can execute the command user password to change the login password of other operators (including those of themselves), but the Admin cannot change the password of other Admins. An Oper can only change his own password, and the original password must be available when changing the password. An Exec cannot change the password of himself.

For example: an Admin changes the password of operator “bbb”:

IAD2000(config)# user password

User Name(<=15chars): bbb

New Password(<=15chars):

Confirm Password(<=15chars):

Changed ok!

Continue?[Y|N] n

4.3.5 Setting Reenter Number for the Operator

The reenter number of an operator is generally set as 1 when the operator is added into the system. If the reenter number of a certain operator should be changed, the Root or Admin can do the job.

The Root can change the reenter number of all the operators The Admin can change the reenter number of Oper and Exec, but cannot change

that of other Admins. The Oper and Exec cannot change any reenter number.

Note:

The reenter number of an operator ranges from 0 to 4. When it is 0, the operator cannot log in the system.

For example: change the reenter number of operator “bbb” to 2:

IAD2000(config)# user reenter

User Name(<=15chars): bbb

Permitted Reenter Number(0--4): 2

Confirm Reenter Number(0--4): 2

Changed ok!


4-17

Continue?[Y|N] n

4.3.6 Setting Operator Appendix Information

The operator appendix information is a supplementary on the operator, which can be the contact methods and address of the operator.

Root and Admin can change the appendix information of all the operators that have a lower authority, Oper can only change the appendix information of himself, Exec cannot change his own appendix information.

For example: if the Root shall set the telephone number of operator “huawei” as 0755-26540808:

IAD2000(config)# user apdinfo

User Name(<=15chars): huawei

User Append Info: 0755-26540808

Changed ok!

Continue? [Y|N] n

4.3.7 Showing Operator Information and Disconnecting an Operator

I. Showing operator information

Showing terminal user

To manage an operator, you may need to know the information about all the operators or an individual operator.

You can use the command show terminal user username to display the information of an operator, or use the command show terminal user all to display the information of all the operators, or use the command show terminal user online to display the information of all the online operators.

Operator information contains the user name, authority, status (online/offline), reenter number and appendix information.

For example: show the information of operator “huawei”:

IAD2000> show terminal user huawei

-------------------------------------------------------------------

Name Level Status ReEnterNUM AppendInfo

-------------------------------------------------------------------

huawei ADMIN OFFLINE 3 TEL:0755-6540808

-------------------------------------------------------------------

Showing client


4-18

Sometimes you may need to know from which terminal an operator has logged in, the IP address of the terminal, and the Client ID. In this case, you can execute the command show client.

For example: show the information of an operator who has logged in:

IAD2000> show client

------------------------------------------------------------------

Operator who maintains the system through the serial port has a fixed Client ID of 1, and the IP address displays as 0.0.0.0. In the example, the Client Name is “---”, which means there is no login on the serial port at present.

II. Disconnecting an operator

You can use the command user disconnect clientid to disconnect an operator who logs in through a Telnet connection. When using this command, you should input the Client ID, which can be obtained through the command show client.

For example: disconnect the operator who logs in from 10.11.136.23 (the Client ID is 3):

IAD2000#user disconnect 3

Note:

A higher-authority operator can disconnect the lower-authority operators. Root and Admin cannot be disconnected through the command user disconnect. Operators logged in from serial port cannot be disconnected through the command user disconnect.

4.4 Log Management

IAD132E(T) provides log function to record the operation and maintenance information of the system (including the remote maintenance information). IAD132E(T) can record the latest 512 pieces of operation logs, and some of the important information can be recorded on the internal loghost through syslog mechanism. To implement log function, you should assign the IP address of the log host on IAD132E(T), and make necessary configuration on the log host.

4.4.2 Adding a Log Host

I. Syntax

The log host receives the log information generated from the system. You must add the parameters of this log host into IAD132E(T), otherwise, the log information will not be sent to the log host, and the operators cannot query the log information from the log host.

In the global config mode, use the command loghost add ip hostname to add a log host.

For example: add a log host SZ-ABC-LOGHOST_1, with the IP address as 210.11.123.56:

IAD2000(config)# loghost add 210.11.123.56 SZ-ABC-LOGHOST_1


4-20

II. Parameters

ip: IP address of the log host, in dotted decimal notation.

hostname: name of the log host, a string of no more than 32 characters.

Note:

An added log host must be activated before log information can be reported to it. The names and IP addresses of the log hosts cannot repeat with each other. The naming method of log host is similar with that of the IAD device.

4.4.3 Deleting a Log Host

In the global config mode, use the command loghost delete {ip | hostname} to delete a log host.

For example: delete the log host with IP address as 210.11.136.56:

IAD2000(config)#loghost delete 210.11.123.56

Note:

You can delete a log host according to its IP address or host name. If the IP address of a log host has changed, or it is no longer in use, you should delete the log host.

4.4.4 Activating a Log Host

In the global config mode, use the command loghost active { ip | hostname } to activate a log host.

For example: activate the log host with IP address as 210.11.123.56:

IAD2000(config)#loghost active 210.11.123.56

Activate the log host SZ-ABC-LOGHOST_1:

IAD2000(config)#loghost active SZ-ABC-LOGHOST_1


4-21

Note:

An added log host must be activated before log information can be reported to it. You can activate a log host according to its IP address or host name.

4.4.5 Deactivating a Log Host

In the global config mode, use the command no loghost active { ip | hostname } to deactivate a log host.

For example: deactivate the log host with IP address as 210.11.123.56:

IAD2000(config)#no loghost active 210.11.123.56

Deactivate the log host SZ-ABC-LOGHOST_1:

IAD2000(config)#no loghost active SZ-ABC-LOGHOST_1

Note:

A log host is able to be activated according to its IP address or host name. You can deactivate a log host that is not used for the time being.

4.4.6 Showing Operation Log Information

I. Syntax

In the user mode, an Oper can execute the command show log detailed index1 [index2] to display the operation log information according to the index numbers.

Note:

If a command string is long, you can use the command show log detailed to see the detailed display. If you use the command show log list, only the characters in the front part will be displayed, and the rest will be replaced with “…”.

For example: display the detailed log record with index numbers 10 to 12:

IAD2000>show log detailed 10 12


4-22

10 configure terminal

11 pots circuit-test 2/0

12 pots loop-line-test 2/0

II. Parameters

index1: start index number of the log record to be displayed.

index2: end index number of the log record to be displayed, which cannot be smaller than index1: by default, only the log record corresponding to index1 will be displayed.

4.4.7 Showing Operation Log List

I. Syntax

In the user mode, an Exec can execute the command show log list username [date] to display the log list of a certain operator, and execute the command show log list all [date] to display the log lists of all the operators. You can query the log records according to specific operator, or according to time segment. If you do not specify the time segment, all the records will display.

Through this command, the configuration made on the device through CLI terminal can be queried. Meanwhile, you can also see what kind of configurations have been made by which operator on the device. If it is found that an operator makes frequent illegal configurations, you can change the operator’s authority to a lower level, or cancel the operator’s authority.

For example: display the operation log of operator “qqq”:

IAD2000>show log list qqq

4.4.9 Setting the Information Output Control Switch of the Log Host

I. Syntax

On IAD132E(T), the information type switch must be turned on before the information of such type can be reported to the log host. Refer to 3.1.6 for detailed description on the control switch.

In the global config mode, execute the following command to set the information output control switch for the log host.


4-24

infoswitch syslog {ip |hostname} {syslog value | oprlog value | debug value | alarm value | trace value | diagnose value | stat value | other value}

Note:

This command is used to change the control switch that already exists on the log host. The modification can be made according to the information type, and you can modify multiple types of information in one time. When executing this command, related log host must be activated.

For example: set the information output control switch for the log host SZ-ABC-LOGHOST_1 as: diagnose information – off, others – on:

IAD2000(config)#infoswitch syslog SZ-ABC-LOGHOST_1 alarm on debug on

diagnose off oprlog on other on stat on syslog on trace on

II. Parameters

ip: IP address of the log host

hostname:name of the log host

syslog: system log information type

oprlog: operation log information type

debug: debugging information type

alarm: alarm information type

trace: tracing information type

diagnose: diagnose information type

stat: statistics information type

other: other information type

value: value of the information output switch, which can be “on” or “off”. “on” means the information can be output, “off” means the informaitn cannot be output.

4.4.10 Setting the Information Output Level of Log Host

I. Syntax

In the global config mode, execute the following command to set the information output control level of an existing log host.


4-25

infolevel syslog {ip | hostname} {syslog value | oprlog value | debug value | alarm value | trace value | diagnose value | stat value | other value}

Note:

When setting the information output control level for a log host, such log host must be activated. Related information type switch must be turned on before this setting can take effect. The information type value must be larger than or equal to the set value, so that the information can be reported to the log host. The setting can be made according to the information type, and you can make the setting on multiple types of information in one time.

For example: set the information output control level for the log host SZ-ABC-LOGHOST_1 as 0:

IAD2000(config)#infolevel syslog SZ-ABC-LOGHOST_1 syslog 0 alarm 0 debug 0

diagnose 0 oprlog 0 other 0 stat 0 trace 0

II. Parameters

value: level of the information, which ranges from 0 to 4 (0 is the lowest level, and 4 is the highest level). The information type value must be larger than or equal to the set value, so that the information can be reported to the log host.

4.4.11 Displaying the Information Output Control Switch of Log Host

In the user mode, execute the following command to display the information output control switch of an existing log host.

show infoswitch syslog { ip | hostname } [syslog |oprlog | debug | alarm | trace | diagnose | stat | other ] {ip | hostname}

You can display the output control switch of one or multiple types of information. If no information type has been specified, the information of all the types will display.

For example: display the information output control switches for log host SZ-ABC-LOGHOST_1:

IAD2000> show infoswitch syslog SZ-ABC-LOGHOST_1

The terminal info output switch:

SYSLOG_TYPE:on

OPRLOG_TYPE:on

4.4.12 Displaying the Information Output Control Level of Log Host

In the user mode, execute the following command to display the information output control level of an existing log host.

show infolevel syslog [ syslog | oprlog | debug | alarm | trace | diagnose | stat | other ] { ip | hostname }

Note:

The level of information ranges from 0 to 4 (4 is the highest level). You can display the output control level of one or multiple types of information. If no information type has been specified, the information of all the types will display.

For example: show the output control level for alarm information and “other” information of log host SZ-ABC-LOGHOST_1:

IAD2000> show infolevel syslog SZ-ABC-LOGHOST_1 alarm other

The terminal info output level:

ALARM_TYPE :0

OTHER_TYPE :0

4.5 Alarm Management

The alarm management function of IAD132E(T) implements the recording, setting and statistics on the alarm information. The alarm management function enables efficient management on the device, and ensures its performance. After an alarm has been generated, the system shall broadcast the alarm to the terminals according to the network configuration. In most cases, the alarm information is reported to the NMS terminal and CLI terminal. Whether an alarm message shall be reported to the terminals can be defined through the alarm control function.


4-27

4.5.1 Common Attributes of Alarms

I. Alarm ID

An alarm ID uniquely identifies an alarm. The command show alarm list can be used to display the name of alarm that corresponds to an alarm ID.

Note:

Alarms of the same type are identified by a unique alarm ID of four bytes, like 0x********. You can input the complete alarm ID like 0x********, or input it in decimal scale. The value of an alarm ID ranges from 38 to 1507589.

II. Alarm level

Alarm level indicates the severity of an alarm, which can be critical, major, minor or warning.

Critical alarm is global, and may endanger the normal running of the device, such as a fault that occurs in the power supply system. A critical alarm requires immediate handling by the maintenance person.

Major alarm is partial, like the failure of a board or the physical link. If a major alarm is not handled in time, the service may be interrupted.

Minor alarm is a general alarm that describes the working status of a board or physical link, or an event alarm, like the error codes on a physical link.

Warning may be a change of state, or an event, that does not affect the normal service of the device, but may be of interest to the maintenance and operation person. The recovery prompt of the device is also a warning.

III. Alarm class

The alarms can be classified into event alarm, fault alarm and restore alarm.

IV. Alarm type

IAD132E(T) has five types of alarms: communication alarm, service_quality alarm, process_error alarm, equipment alarm and environmental alarm.

V. Alarm parameter

Alarm parameters help to locate the alarm, and are given in the reported alarm message. For example, an alarm concerning a board may have these parameters: slot number and port number.

4.5.3 Displaying Alarm Records

IAD132E(T) stores the alarm information for query when necessary.

An alarm record contains these items: alarm time, serial number, alarm level, alarm class, alarm type and alarm parameter.

IAD132E(T) can store up to five hundred records of the latest alarms. If the alarm list is full, the new record will overwrite the oldest record.

The following methods can be used to query the latest alarm records:

I. Querying according to serial number

show alarm record alarmsn sn


4-29

The most direct method is to query the alarm according to its serial number. Each alarm record has a unique serial number (according to the time sequence when the alarm occurs), so you can get down to the specific alarm through its serial number.

sn: serial number of the alarm, and the value range is [0, 4294967295].

II. Querying according to alarm ID

show alarm record alarmid id [startnum number]

If you want to know whether a certain type of alarm has ever occurred, you can make the query according to alarm ID.

id: alarm ID

number: maximum number of alarm records after the startnum that can be displayed in one time. This is an optional parameter, the value is [1, 1500]. The default is 500.

startnum: the alarm number from which the display starts, the value is [1, 1000]. In the CLI, you can start the display from 1, or from a designated startnum.

III. Querying according to alarm level

show alarm record alarmlevel level [startnum number]

This method is suitable when you only care about the alarms of a certain level.

level: alarm level, just input the severity (critical, major, minor, warning).

IV. Querying according to alarm type

show alarm record alarmtype type_value [startnum number]

You can query the alarms according to their types.

type_value: alarm type, just input the type here (communication, service_quality, process_error, equipment, environmental).

V. Querying according to alarm class

show alarm record alarmclass class [startnum number]

You can query the alarms according to their classes.

class: alarm class, just input the class (event, fault, restore).

VI. Querying according to time

show alarm record alarmtime datebegin timebegin dateend timeend [startnum number]


4-30

You can query all the alarms that occurred in a certain period of time.

datebegin: the displayed alarm starts on this date, the input should be yyyy-mm-dd. yyyy-mm-dd.

timebegin: the displayed alarm starts at this time, the input should be hh-mm-ss. hh:mm:ss.

dateend: the displayed alarm ends on this date, the input should be yyyy-mm-dd. yyyy-mm-dd.

timeend: the displayed alarm ends at this time, the input should be yyyy-mm-dd. hh:mm:ss.

VII. Querying the latest alarms

show alarm record all

You can query all the latest alarms that occurred.

Note:

IAD132E(T) stores five hundred alarm records. If you need to query the alarms that occurred even earlier, you can display them through the database on the NMS.

4.5.4 Querying Alarm Contents

Command is available for you to query the contents of a certain type of alarm.

In IAD132E(T), an alarm has the following attributes: alarm ID, alarm name, alarm level, default alarm level, alarm type, alarm class, CLI output tag, statistics tag, number of parameters, 15 minutes threshold, 24 hour threshold, and detailed explanation on the alarm.

The command to query alarm contents is this:

show alarm content alarmid

alarmid: alarm ID

4.5.5 Setting Alarm Levels

Alarm level indicates the severity of an alarm. A fault alarm always corresponds to its restore alarm, and both the alarms are in the same level.


4-31

I. Setting alarm level

Each alarm has a default alarm level, and the global command alarm level alarmid alarmlevel can be used to set a new level for an alarm, or restore its default level.

alarmid: alarm ID

alarmlevel: alarm level, just input the severity (critical, major, minor or warning). If you input “default”, the alarm level will restore to the default one.A restore alarm is in the same level with its original fault alarm, and this is set by the system automatically. That is, when you set the alarm level for a fault alarm, the system will set its restore alarm to the same level. Similarly, when you set the alarm level for a restore alarm, the system will set its original fault alarm to the same level.

II. Querying the result

The command show alarm content alarmid can be used to check the execution result of the command.

Caution:

You must be careful when setting the alarm levels. Generally, the default settings are proper. If necessary, you can restore to the default settings after you have changed the setting.

4.5.6 Setting the Alarm Output to CLI Terminal

After an alarm is generated, it will be reported to the CLI terminal by default. However, different operators may care about different contents of the alarm. So IAD132E(T) provides shielding function on the alarms.

Note:

There are two switches that control the output of an alarm to the CLI terminal. Switch 1: use the command infoswitch cli to set whether to report the alarm information to the CLI terminal. Switch 2: use the command (no) alarm output to set whether to report the alarm information to CLI terminal according to preset conditions. To sum up, switch 1 controls the output of all the alarm information, while switch 2 controls conditional output of alarms. Refer to 4.1.6 for the use of switch 1.


4-32

Each alarm has an output tag that decides whether such alarm can be reported to the CLI, and the setting is actually made on this tag. The output tag of a restore alarm is the same with its original fault alarm.

You can set the output tag according to alarm ID, alarm level or alarm type, or set to output all the alarms.

The command is like this: (no) alarm output

“no” is optional, and no alarm output means not to output a certain type of alarms to the CLI terminal. alarm output means to output a certain type of alarm to the terminal.

I. Setting according to alarm ID

An alarm ID corresponds to a specific type of alarm, so this command helps you to set exactly whether to output a certain type of alarm.

(no) alarm output alarmid id

id: alarm ID

II. Setting according to alarm level

If you do not care about the low-level alarms, this command helps you to disable the output of them.

no alarm output alarmlevel level


III. Setting according to alarm type

(no) alarm output alarmtype type_value

type_value: alarm types, just input the type name (communication, service_quality, process_error, equipment, environmental).

IV. Setting the output of all alarms

The command is available to set the output of all the alarms:

(no) alarm output all

V. Querying the result



4-33

VI. Remarks

Your setting is effective to all the CLI terminals. That is, an alarm will be reported either to all of the CLI terminals, or none of the terminals.

The output tag of a restore alarm is the same with its original fault alarm. This is implemented by the system automatically. That is, when you set the alarm output tag for a fault alarm, the system will set the same tag to its restore alarm. Similarly, when you set the output tag for a restore alarm, the system will set the same tag to its original fault alarm.

Caution:

This alarm output shielding is invalid to NMS terminal, because the NMS provides even more filtering functions on the alarm output. The setting of alarm output does not have any effect on the generation of alarms. After the setting, any alarms generated will still be recorded, and can be queried through the history command. Different settings on the output tag may affect each other, and the last setting on the output tag will take effect. For example, if a “major” alarm belongs to the type of “communication”, and you have set not to output the “major” alarms, and then set to output the “communication” alarms. As a result, this alarm will be output to the CLI terminal.

4.5.7 Setting Alarm Statistics

Alarm statistics is to accumulate and count a certain type of alarms that occur in a specific period of time. Alarm statistics records the frequency in which a certain type of alarm occurs, and sends threshold alarm (if any) to the maintenance person to handle the alarm (refer to 4.5.8 for the setting of alarm threshold).

In IAD132E(T), the alarm statistics is made on the basis of two time periods: 15 minutes and 24 hour.

Alarms with the same alarm ID belong to the same type. Alarms of the same type have a unique tag that specifies whether statistics are required on them. By default, no statistics shall be made on the alarms. However, you can set statistics function on the alarms that you are concerned about.

Like the setting of alarm output tag to the CLI terminal, you can set the alarm statistics tag according to alarm ID, alarm level, alarm type, and set statistics on all the alarms.

The command to set alarm statistics is like this: (no) alarm statistics


4-34

“no” is optional, and no alarm statistics means not to make statistics on a certain type of alarm. alarm statistics means to make statistics on a certain type of alarm.

I. Setting according to alarm ID

An alarm ID corresponds to a specific type of alarm, so this command helps you to set exactly whether to make statistics on a certain type of alarm.

(no) alarm statistics alarmid id

II. Setting according to alarm level

If you do not care about the low-level alarms, and only need the statistics of the high-level alarms, this command helps you to set the statistics of all the alarms in a certain level.

(no) alarm statistics alarmlevel level


III. Setting according to alarm type

You can set the alarm statistics according to alarm types.

(no) alarm statistics alarmtype type_value

IV. Setting statistics on all the alarms

(no) alarm statistics all

V. Querying the result



4-35

Caution:

Different settings on the alarm statistics tag may affect each other, and the last setting on the statistics tag will take effect. For example, if a “major” alarm belongs to the type of “communication”, and you have set not to make statistics on the “major” alarms, and then set to make statistics on the “communication” alarms. As a result, this alarm will be included in the statistics. In actual application, the statistics tag on a fault alarm and its corresponding restore alarm can be different, since the concern on them are generally different. So, the setting of fault alarm statistics and restore alarm statistics are independent of each other. Alarm statistics for threshold alarms cannot be set.

4.5.8 Setting Alarm Threshold

When the statistics tag of a certain type of alarm is turned on, statistics will be made on the alarms based on different threshold values.

In IAD132E(T), each type of alarms can have two statistics thresholds: 15 minutes threshold and 24 hour threshold. If it does not matter whether the statistic threshold is exceeded, you can set the threshold to 0. If the threshold is not 0, once the number of alarm statistics exceeds the value, a threshold alarm will be generated. The default alarm statistics threshold is 0.

The following describes the setting methods:

I. Setting alarm threshold

The following command is used to set the 15 minutes and 24 hours alarm thresholds.

alarm threshold alarmid threshold15m threshold24h

alarmid: alarm ID

threshold15m: 15 minutes threshold, an integer between [0, 65535].

threshold24h: 24 hour threshold, an integer between [0, 4294967295].

The 15 minute threshold must not be larger than the 24 hour threshold.

II. Querying the result

The command show alarm content can be used to display the alarm threshold, and check the execution result of the command.


4-36

Caution:

In actual application, the statistics of a fault alarm and its corresponding restore alarm can be different, since the concerns on them are generally different. So, the settings of statistics thresholds for fault alarm and restore alarm are independent of each other. If you set the threshold as 0, no threshold alarm will be generated.

4.5.9 Querying Alarm Statistics

The maintenance person often needs to know the frequency of the occurrence of a specific type of alarms, in order to be clear about the status of the equipment, and analyze possible faults.

The alarm statistics are provided on the basis of four time segments: current 15 minute, current 24 hour, previous 15 minutes, and previous 24 hour. That is to say, the alarm statistics information can be stored in the system for two days.

The following command is used to query the alarm statistics information:

show alarm statistics alarmid [startnum number]

number: number of alarm statistics to be displayed, which is an optional value between [1, 500]. The display sequence is from the latest alarm to the oldest alarm. The default setting is 500, which means 500 pieces of alarm information will be displayed.

startnum: the alarm number from which the display starts, the value is [1, 500]. In the CLI, you can start the display from 1, or from a designated startnum.

4.5.10 Clearing the Statistics

If IAD132E(T) has stayed idle for long, or the alarm statistics data has been destroyed, you should clear the alarm statistics by yourself.

The command to clear the alarm statistics is:

alarm statistics clear

After this command is executed, the alarm statistics will be cleared, and the previous alarm statistics will no longer exist.

If a certain type of alarm does not occur in two days, its statistic information will be cleared automatically by the system. So in normal circumstances, you do not need to clear the alarm statistics.


4-37

4.5.11 Querying the Basic Alarm Settings

The following command displays whether alarm ID is output to terminal, whether statistics is made, and the alarm name.

show alarm list {{from alarmid1 to alarmid2}|all} [startnum number]

If you do not know which alarms exist in the system, execute the command show alarm list all to query the name of alarms corresponding to a certain alarm ID.

4.6 Testing Equipment

IAD132E(T) provides abundant equipment test functions. You can perform online test to the equipment through the command line in the equipment test mode.

4.7 Setting Alarm Thresholds

4.7.1 Setting RTCP Thresholds

The real-time transport control protocol (RTCP) packet contains the statistical results of the round-trip delay, delay jitter and packet loss ratio of the real-time transport protocol (RTP) channel. A RTP packet is voice packet generated in a call.

When the operational values of the system exceed the RTCP packet threshold, the thresholds of the round-trip delay, delay jitter and packet loss ratio of the RTP channel, or the threshold of the interval between sending two RTCP packets, an alarm is generated. The related commands are as follows. The command for setting the thresholds is carried out in the global configuration mode; the command for querying the status of the thresholds is carried out in the user EXEC mode.

Table 4-9 Commands related to RTCP alarm thresholds


Setting RTCP threshold

rtcp_para { alarmthreshold alarmthreshold | lost lost | delay delay | jitter jitter | timer timer }*

Global configuration mode

Query RTCP threshold status show rtcp_para User Exec mode


4-39

Alarmthreshold: Threshold of alarm RTCP packet, that is, an alarm is generated after the parameters delay, jitter and lost of how many RTCP packets in a row exceed the thresholds. The value range is 0 to 5, and the default value is one packet. If it is set to 0, it means no alarm is generated regardless of the network status; that is, the alarm and log function of RTCP is disenabled.

Delay: Round-trip delay of the RTP channel. The value range is 50 to 1,000 milliseconds. The default value is 50 milliseconds.

Jitter: Delay jitter of the RTP channel. The value range is 10 to 150 milliseconds. The default value is 20 milliseconds.

Lost: Packet loss ratio of the RTP channel. The value range is (0 to 150)/1000. The default value is 50/1000.

Timer: The time interval between sending RTCP packets. The value range is 5 to 20 seconds. The default value is five seconds.

For example:

Set the RTCP alarm thresholds as follows:

IAD2000(config)# rtcp_para alarmthreshold 2 lost 150 delay 100 jitter 100

timer 10

Query the current RTCP threshold settings:

IAD2000(config)#show rtcp_para

lost rate of RTP channel :150/1000

delay of RTP channel :100ms

jitter of RTP channel :100ms

timer len of RTCP channel :10s

alarm threshold of RTCP channel :2

4.7.2 Setting Temperature Thresholds for Starting Fan and Generating Alarm

The IAD132E(T) is usually installed in areas with poor conditions such as corridors. To ensure normal operation, the internal temperature of the equipment must be controlled. An internal fan is installed in the IAD132E(T) to dissipate heat. Temperature thresholds can be set in data configuration. When the temperature exceeds the threshold, the internal fan automatically starts. If the temperature rises further and exceeds the alarm threshold, an alarm is generated. After the temperature drops below the threshold for starting the fan, the fan automatically stops operation.

Global configuration mode

Showing temperature threshold for starting fan and alarm temperature threshold show temperature-limit User EXEC mode

temperature-value: Temperature value. The default value is 0 to 200.

For example:

Set the IAD132E(T) temperature threshold for starting the fan to 50°C, and the alarm temperature threshold to 60°C:

IAD2000(config)#temperature-limit fan 50 alarm 60

Start fan temperature threshold is: 50(.C)

alarm temperature threshold is: 60(.C)

4.8 Managing Patches

4.8.1 Overview of Patches

IAD132E(T) is required to run without interruption for a long time. To amending some software problems or adding new functions, you need to modify the host software without interrupting the service, that means patch the host software.

In IAD132E(T) the patches have three statuses.

Deactive: The patch has been added into the host but not activated, and the patch code takes no effect.

Active: The patch code takes effect and its status can be modified by executing commands patch start and no patch active.

Running: The patch is in running status and can only be deleted rather than be deactivated.


4-41

Note:

The difference between Running status and Active status is that the patches in Running status can automatically recover to Running status after the system is rebooted, while those in Active status will become Deactive after rebooting. The Active status can be regarded as the “trial running” of the patch. Through the trial running you can check whether the expected functions are achieved. Only the patches passed the trial running test can be used normally.

The system provides the following commands for patching.

Activating the patch: patch active Deactivating the patch: no patch active Running the patch normally: patch start Deleting the patch: patch remove Displaying the information of the patch: show patch

4.8.2 Steps of Operating Patches

Patches can be operated in the following sequence:

1) Through command load patch in the diagnosis mode, load the patch file to CVP board. If the loading succeeds, you can check the information of the patches by executing command show patch.

2) After checking that the patch is correct, you can execute command patch active to activate the patch. If the activation succeeds, you can verify the functions of the patch or test the functions.

3) After verifying the functions, you need to run the patch normally. To do this, you need to execute command patch start to transfer the patch status to the Running status.

4.9 Network Test Tools

This part introduces the most common tools used to test the network connectivity.

4.9.1 ping

ping command is used to check the status of network connection, and whether the destination host is reachable. The command is like this: ping hostip, and you can put in one or multiple parameters, as listed in Table 4-7.

This command is executed in the user mode, and can be terminated by pressing <Ctrl+C>.


4-42

Table 4-11 Parameters used with the “ping” command

Parameter Meanings

-c Set the number of Internet Control Message Protocol (ICMP) ECHO_REQUEST packet to be sent. If it is set to 0, it means that the packets can be sent unlimited times.

-d Set socket debugging function.

-i Set to send the ECHO_REQUEST to the directly connected network without route selection.

-p Set the filler octet for the sent ECHO_REQUEST packet. For example, -p 0xff means to fill the packet with 000000ff.

-q Display only the statistics number instead of detailed information.

-s Set the length of ECHO_REQUEST packet.

-t Set the timeout second for ECHO_REQUEST reply.

-v Display the received non ECHO_RESPONSE ICMP packets, by default, there is no display.

For example:

IAD2000>ping -c 100 210.11.180.18

Reply from 210.11.180.18 : byte=32 time=2ms TTL=123



……


4.9.2 tracert

tracert command is used to trace through which gateway devices a data packet passes on its way from the host to its destination. This command helps to check the network connection, and locate the fault.

The command is like this: tracert hostip, and you can put in between one or multiple parameters, as listed in Table 4-8.

This command is executed in the user mode, and can be terminated by pressing <Ctrl+C>.

Table 4-12 Parameters used in command tracert

Parameter Meanings

-d Set the debugging print switch

-f Set the minimum value of TTL

-m Set the maximum value of TTL


4-43

Parameter Meanings

-q Set the number of tracert packets

-w Set the timeout value

The tracert process is like this:

1) A data packet with TTL as 1 is sent. 2) An ICMP error message is returned from the first hop device (since TTL times out,

the packet cannot be sent). 3) A data packet with TTL as 2 is sent. 4) TTL timeout message is returned from the second hop device. 5) This process repeats until the packet is sent to the destination.

The purpose of doing so is to record the source address of each ICMP TTL timeout message, so that to obtain the route through which a data packet reaches its destination.

4.9.3 Sample Application

I. Application 1

Networking: as shown in Figure 4-1, the maintenance network port of IAD132E(T) connects with the maintenance terminals 1 and 2 through a LAN, the IP addresses of them are 10.11.88.12, 10.11.88.18 and 10.11.88.19 respectively.

Fault: Sometimes you can Telnet IAD132E(T) successfully from terminal 1, but sometimes you cannot, while you can always Telnet IAD132E(T) from terminal 2.

Processing:


4-44

Telnet IAD132E(T) from terminal 2, execute the ping command to check the connection between IAD132E(T) and terminal 1:

1) Use the default parameters of ping command to ping terminal 1: IAD2000> ping 10.11.88.18

2) No reply can be obtained for the ping command. 3) Add a parameter “c=10” in the ping command and send ten packets

continuously to terminal 1 to check the packet loss rate: IAD2000> ping -c 10 10.11.88.18

4) Among the ten packets, only five of them get reply, and the packet loss rate is very high.

The possible reasons for this could be that the physical link between terminal 1 and IAD132E(T) is unstable, or the network is busy, or there is interference.

From the above result, you can see which gateway devices the signal has passed through on its way from the source device IAD132E(T) to the destination SoftSwitch. This is very helpful in analyzing failures in the network.

Operation Manual U-SYS IAD132E(T) Integrated Access Device Chapter 5 Troubleshooting

5-1

Chapter 5 Troubleshooting

This chapter first introduces common means of locating IAD faults so that you can master simple fault-locating methods. It then gives some examples on IAD faults for your reference.

5.1 Common Fault-locating Means

5.1.1 Showing Important System Information

I. Showing Version

Obtaining the software version of the equipment is the basis of locating its faults. If the software the IAD132E(T) uses is not the latest version, some of its problems may have been solved in a subsequent version. In this case, you can locate some problems from the version number and get corresponding solutions.

By carrying out the show version command in the user EXEC mode, you can show the software and hardware version of the equipment.

IAD2000#show version

Equipment type : IAD132E(T)

SLOT 0 CVP mainboard version information

PCB version : AG11CVP.2

BIOS version : 303

Software version : IAD2000V100R002B01D020

CPLD-A version : 100

CPLD-B version : 102

SLOT 1 ATI interface board version information

PCB version : AG11ATI.1 REV.A

Chip version : 2

SLOT 2 ASIB interface board version information

PCB version : AG11ASI.2 REV.A

Chip version : 19

SLOT 3 ATU interface board version information

PCB version : AG11ATU.1 REV.0

Chip version : 0

II. Showing Interface Status

Once there is a system fault leading to service failure, you should first check MG interface information. Calls can be made only when the interface status is normal. Otherwise, the subscriber hears the busy tone after hooking off.


5-2

You can use the show if-mg attribute command to show the MG interface settings of the IAD132E(T) and check if the parameter settings are consistent with those of the MGC.

IAD2000#show if-mg attribute 0

----------------------------------------------------------------

MGCport MGCIP/DomainName InterfaceName

2727 172.21.1.1 aaln

------------------------------------------------------------------

III. Showing Port Status

By showing the port status, you can check the status of each subscriber. The status of a port in normal use is idle or busy.

You can use the show port state command in the user EXEC mode to show the port status:

IAD2000#show port state 2

--------------------------------------------------------------------

Slot/Port PortType State ServiceType ServiceState

--------------------------------------------------------------------

2 / 0 FXS Idle Instant service Start service
















--------------------------------------------------------------------


5-3

IV. Showing Time of System Restarting

You can use the show clock command to show when the system is reset and restarted.

IAD2000#show clock

--------------------------------------------------

Date when the system starts: 2003-10-24 Time: 00:38:40

Current date: 2003-10-24

Current time: 16:58:11

--------------------------------------------------

V. Showing IP Address and Route Information

When a network fault occurs, you need to show the following information. Use the four commands specified in Table 5-1 to locate the fault.

Table 5-1 Common commands to show information on network faults

Function Command Note

Showing if DHCP has been enabled (User EXEC mode)

show dhcp There must be a DHCP server to enable DHCP.

Showing IP address (User EXEC mode)

show ip address -

Showing route information (Privileged user mode)

show ip route Incorrect route information may lead to interface faults, monologs, or communication failures.

Showing ARP entry in IAD (User EXEC mode)

show ip arp -

VI. Showing RTP Statistical Information

You can carry out the show rtp stat command to show information on media stream.

IAD2000(config)#show rtp stat 2/6

slot ID/Port ID RTP channel index RTP channel status remote

IP address

2/6 0 open 10.71.37.42

number of packets sent number of bytes sent loopback delay (millisecond)

number of packet lost


5-4

2760 474720 10 0

jitter (millisecond)

0

The parameters displayed by this command have the following meanings:

number of packets received (sent) = call duration (second) X 1000/length of packet received (sent)

Code type:

0 means G.711u

4 means G.723 high

8 means G.711A

18 means G.729

20 means G.723Low

Under good network conditions, jitters are usually less than 30 milliseconds (ms). After querying for multiple times, the difference between the number of packets

received and that of packets sent is fixed.

5.1.2 Showing Alarms

Alarm information is part of the history records on equipment operation. By analyzing alarm information, you can predict problems that may arise in the running of the equipment. Note that when the IAD132E(T) encounters a power failure and is restarted, the alarm records saved before will be lost.

The command to show all alarms is show alarm record all. For other commands to show alarms, refer to the help information.

The following alarms require your special attention:

I. System Start Alarm

This alarm tells you the system start time and whether the system was reset while it was running.

ALARM 21 running information: important 0x00000336 ----- 2003-10-24 00:38:43

Alarm name: Equipment startup

Parameter information: Equipment startup

Alarm description: Equipment startup

Alarm cause: None.

Suggestion for restoration: None.

II. Interface Interruption/Recovery Alarm

Interface interruption is generally caused by network conditions. When interface interruption occurs, no phone calls can be made. If you hear busy tone or no tone after offhook, you should first check if there is an interface interruption alarm.


5-5

If multiple IAD132E(T) devices in the same area generate interface interruption alarms almost at the same time, the problem is usually caused by the bearer network. It is that normal each system startup is accompanied by an interface recovery alarm.

ALARM 2 recovery alarm important 0x00170105 communication category 2003-10-23

09:58:38

Alarm name: MG interface interruption recovery alarm

Parameter information: MG interface identifier: 0

Alarm description: The MG interface returns to normal.

Alarm cause: The MG interface is normal.

Suggestion for restoration: None.

--- END

5.1.3 Catching Network Packets

To locate faults in a Voice over IP (VoIP) device by capturing packets, we recommend Sniffer pro 3.0.

All IAD132E(T) signaling and voice data are borne on the user datagram protocol (UDP). The protocol stack architecture is as follows:

Table 5-2 The UDP stack

Telnet remote maintenance Voice Call control

Telnet RTP RTCP MGCP

TCP UDP

IP

MAC

The key protocols are RTP and MGCP.

5.2 IAD Port ID Error Leads to Call Failure.

5.2.1 Symptom Description

In the IP access network (IPAN) networking, a subscriber under a port of the IAD hooks off and hears the dialing tone, but cannot dial successfully. Meanwhile, other ports are normal.

5.2.2 Causal Analysis

If some ports are unavailable while others are normal, it means the IAD has been successfully registered and the fault is caused by a subscriber port ID error. The error may be in the User ID on the ETG, the corresponding relations between the L3 addresses on the ETG and that on the switch, or the Interface ID (aaln/X) on the IAD.


5-6

Perform the following steps to troubleshoot the port error:

1) Carry out the show mg ag all command on the ETG to check if the corresponding IAD has been successfully registered.

2) Carry out the show port command on the IAD to check if the port and the corresponding subscriber phone set are normal. If they are not normal, it is usually caused by subscriber board faults.

3) If the IAD port is normal, carry out the show pstn-port command on the ETG to show the IAD port status. If the status is not normal, it is generally because the L3 address does not correspond or the subscriber data has not been configured.

Different IADs may have different models and are produced by different manufacturers; therefore, their coding modes may be different. The port IDs of the IAD132E(T) starts with 0.

The IP console must correspond to two user IDs, and the first port ID must be an even number.

5.2.3 Processing Procedure

1) Make test calls to confirm that some port cannot process dialing but other ports can. Then check the external line to rule out related causes.

2) Carry out the show port command on the IAD to show the IAD port. If the port is normal, carry out the show pstn-port command on the ETG to show the IAD port status is normal.

3) Closely examine the interface ID on the IAD, and you can find that the ID of the first port is aaln/1; however, the ID of the first port of the IAD132E(T) should be aaln/0. Other ports are numbered in order. After the modification is saved, test calls show that the problem remains.

4) Carry out the show user-endpoint-info-cfg command on the ETG, and you will find that the user ID corresponding to the IP console is 32, and the user ID corresponding to the first subscriber port is 33. Re-collate the user IDs. Make the IP console correspond to the user ID of 32. Leave 33 unused. Make the first subscriber port correspond to 34. Number other ports by order. Save the data. Make test calls, and you will find the problem is solved.

5.2.4 Suggestion and Summary

In deployment, you should understand the following parameters on the switch, ETG and IAD:

L3 address: Both the switch and ETG have this parameter. The L3 addresses on the two devices correspond to each other on a one-to-one basis. The switch uses the L3 address to correspond to the end subscriber on the IAD port through the ETG.

UserId: It is also called subscriber number. Only the ETG has this parameter. Corresponding relations between the L3 address on the switch and the IAD port ID are


5-7

achieved through UserID. The process is as follows: Corresponding relations between UserID and L3 address are achieved through “add user-v5-info-cfg”; corresponding relations between UserID and IAD port ID “aaln/X” through table “add user-endpoint-info-cfg”.

interface ID: Its format is aaln/X (X is an integer from 0 to 32). This parameter exists in the ETG and IAD. It corresponds to the subscriber port ID on the IAD. The port IDs of the IAD132E(T) starts with aaln/0.

5.3 There Is an Echo When Making PSTN Calls.

5.3.1 Fault

Networking: The IAD allocates private IP addresses. It connects with the metropolitan area network (MAN) through network address translation (NAT) and networks with the BISC software of company S. The IAD is the IAD132E(T). Make a PSTN call from a phone set under the IAD. The communication on the IAD side is normal, but there is an echo on the PSTN side.

5.3.2 Cause

Analysis of on-site packet capture result shows that, in the signaling delivered by the softswitch, both “e:on” and “s:on” are on. The packet is as follows:

2b: [131][14:09:15.190]Recieve From MGC:CRCX 12762 aaln/[email protected] MGCP 1.0C: 1M: inactiveL: p:10, a:PCMA, b:64, e:on, s:onQ: loop,processR: G/ft(N),G/mt(N)S: X: 1200177206000C00

The softwitch of company S enabled echo cancellation (EC), and EC operates on the peer end; therefore, an echo is hear on the PSTN side.


According to the internal flow of the IAD and SoftX3000 of Huawei, when the IAD networks through NAT, EC and VAD on the IAD side should be set to “off”, and they should not be seen in the signaling returned by the IAD. After EC and VAD on the softswitch of company S are disenabled, the fault disappears and communication returns to normal.

5.4 When IAD Subscriber Calls Subscribers of Other Local Carriers, Their Phone Sets Can Ring, but Call Cannot be Made.

5.4.1 Fault

A carrier's networking consists of the SoftX3000 plus IAD and TMG8010. When an IAD user calls a user of other carriers, the call needs to go out through the TMG8010. In the


5-8

local equipment room there are an IAD and TMG8010, which connect to the LAN Switch and router. The IAD can successfully calls a subscriber of other non-local carriers. If the subscriber calls a subscriber of other local carriers, the phone set of the callee can ring. However, when the callee hooks off, there is no tone, and neither side can communicate.

5.4.2 Cause

The call signaling flow of the IAD subscriber is “IAD--SoftX3000--TMG8010—other carriers”. Analysis of the fault shows that the phone set of the callee can ring, which means that communication between IAD and SoftX3000 and that between TMG8010 and SoftX3000 are normal.

The call flow of the IAD subscriber is “IAD--TMG8010—other carriers”. Since calls from the IAD to a non-local TMG8010 is normal, communication between IAD and non-local TMG8010 is normal. Since calls from the IAD to other local carriers are abnormal, the problem should be that communication between IAD and local TMG8010 is abnormal.

Check the IP address settings of the IAD and TMG, you can see that the IP address of the IAD is set to 10.14.96.103/26, while that of the TMG8010 is set to 10.14.96.101/29. The setting of the mask of the TMG8010 is too low, which leads to communication failures between TMG8010 and IAD.


1) The address of the SoftX3000 can be pinged through from both the IAD and the TMG8010.

2) Make the IAD and the TMG8010 ping each other. If they cannot be pinged through, it means the circuit is not through.

3) Modify the mask of the TMG8010 to 26 digits. Then the fault disappears.

5.5 Monolog Occurs When IAD and OPENEYE Call Each Other.

5.5.1 Fault

Monolog occurs when the IAD and OPENEYE directly call each other. The voice from the IAD side cannot be heard on the OPENEYE (SIP-based). After various models of IAD, including 101, 102 and 108, are tried, the problem remains. However, communication between IADs is normal, both IAD and OPENEYE are successfully registered, and their interaction with the softswtich is normal.

5.5.2 Cause

Since the IAD communicate with other IADs normally, IAD hardware faults can be ruled out. You can consider replacing the PC of the OPENEYE.


5-9


1) After installing the OPENEYE in another PC, communication returns to normal. 2) Check the faulty PC. It is a DELL PC installed with two network cards. One

network card (hereinafter referred to as card 1) is integrated on the mainboard; the microphone and headphone interface are also integrated on the mainboard. Another network card (hereinafter referred to as card 2) is plugged in the extended slot of the mainboard.

The IP addresses are as follows:

Card 1 is 10.22.11.9/24, and the gateway is 10.22.11.254. This network port is used to catch the packets of the MGC (whose address is 10.22.11.2).

Card 2 is 10.22.3.201/24, and the gateway is 10.22.3.254.

Peer-end IAD is 10.2.128.65/28. This address can be pinged through from card 1 and card 2.

When card 2 is selected for the OPENEYE, monolog occurs when the OPENEYE and IAD call each other. Voice can be heard on a phone set under the IAD, but the peer-end voice cannot be heard on the OPENEYE.

When card 1 is selected for the OPENEYE, communication is normal.

When the OENEYE is installed in a PC with two network cards, the incoming voice stream must be processed.

5.6 Voice Quality Deteriorates When Photoelectric Transducer Network Port Is Set to Semi-Duplex.

5.6.1 Fault

Jitters occur in communication and voice cannot be heard clearly.

5.6.2 Cause

Since the IADs in other area are normal and several IADs in this office operate like this, it can be seen that this is a network fault.


1) The network blocks pinging. A ping test cannot be conducted. 2) Test the equipment when it is idle. If the problem remains, network bandwidth

problems can be ruled out. 3) Check the negotiation status of the uplink interface and find that it is set by

negotiation to 10M semi-duplex. Maybe it is set to full-duplex on the peer end and to adaptive on our side, and by negotiation it is set to semi-duplex. Modify it to full-duplex. However, the problem remains.


5-10

4) Confirmation shows that mode of the photoelectric transducer is 10M semi-duplex. After it is modified to full-duplex, communication becomes normal.

5.6.4 Suggestion and Summary

Voice communication often generates a bidirectional network traffic. The semi-duplex mode only allows a traffic in one direction at one time, which leads to the problem in voice quality. Where possible, the full-duplex mode should be set.

5.7 IAD Echo

5.7.1 Fault

When the IAD subscriber is in a conversation, there is an echo, and the voice is intermittent.

5.7.2 Cause

This problem is generally caused by the following factors: on the IAD or TG, the echo cancellation parameter is disabled, the silence detection parameter is enabled, or the receiving/sending gain parameter is unreasonably set.

The echo source is generally caused by the peer end. If the IAD subscriber hears the echo, you should adjust the echo cancellation and receiving/sending gain parameters on the TG/ETG. If the PSTN subscriber hears the echo, you should adjust the echo cancellation and receiving/sending gain parameters on the IAD side.


I. Adjusting Echo Cancellation Switch

If the PSTN subscriber hears the echo, carry out the show mg system-parameter command on the IAD to show the IAD system parameters , and carry out the mg system-parameter command to modify them.

Parameter 8 “Dsp echo check” should be set to 1 (enabled).

Parameter 9 silence detection “Dsp silence reduce” should be set to 0 (disenabled).

If the IAD subscriber hears the echo, it may be caused by the TG/ETG. In this case, you need to modify the echo cancellation parameter on the TG/ETG as follows:

Carry out the modify ipp-ch command to modify echo cancellation on every board. Enable parameter 4. If the echo remains, adjust parameter 16 and increase its value. This parameter indicates the buffer value of echo cancellation. Its value range is 0 to 15, and 8 ms is a level.


5-11

II. Adjusting Receving/Sending Gain

Normally, the echo problem can be solved after the above parameter adjustments. If the echo or cut voice (intermittent communication) remains, you need to adjust the gain on the two sides. This problem is caused by improper gain settings which affect EC.

The basic principle for gain adjustment is that the different between the sending gain of the TG and that of the IAD should be as little as possible. In this way, the EC intermittence can be reduced.

Generally, we recommend the sending gain and receiving gain of the TG be both set to 0db, and the sending gain and receiving gain of the IAD be set to –3.5 and 0 respectively. Owing to the network complexity, you need to make on-site adjustments according to the actual situation for maximal effect.

Carry out the mg system-parameter command to adjust the IAD gain. The gain is parameters 3 and 4 (parameter 3 is the DSP input gain, while parameter 4 is the DSP output gain).

Carry out the modify ipp-ch command to adjust the TG gain. Its parameters 14 and 15. The method to calculate the gain is as follows:

The size of the gain is adjustable from -14dB to +6dB. The variation step is 0.1dB. If the step is set to 1, the adjustable gain range is from -140 to +60. To make it easy for subscriber to set this parameter and to avoid negatives, set its value range to from 0 to 200. Then the relationship between the gain parameter set by the subscriber and the actual gain is: actual gain = (gain parameter-140)/10. For example, if the subscriber sets the parameter to 120, the actual gain is (120-140)10 = -2dB. The default value of this parameter is 140, which means the default gain is 0dB.

Generally, the above procedure can solve the echo and cutting voice problem.

5.8 Voice Is Too High or Too Low for IAD Subscribers in Conversation.

5.8.1 Fault

Voice is too high or too low for IAD subscribers.

5.8.2 Cause

Too high or too low voice is related to system gain. This problem can be solved by adjusting the sending gain of the peer end and the receiving end of the local end (including the DSP input/output gain of the voice pinch board and the receiving/sending gain of the subscriber physical port).

The voice quality can be remarkably improved by adjusting the receiving/sending gain of the IAD subscriber physical port. By contrast, the voice quality can also be improved by adjusting the DSP input/output gain of the voice pinch board, but the effect is not


5-12

remarkable. Adjusting the TG gain has an impact on the global office; therefore, it is not recommended.


The receiving/sending gain of the IAD subscriber physical port can be adjusted according to international standards and actual network quality.

By the Chinese national standard, the sending/receiving gain of the local network should be 0/-3.5 (high gain), and that of the toll network is 0/-7. By international standards, the narrowband sending/receiving gain is usually 0/-7. The voice of the IAD is received and sent in RTP packets. This mode is similar to a PCM trunk and can be regarded as a packet trunk. Therefore, it is recommended that the receiving/sending gain of the IAD subscriber physical port be set to0/-7 (low gain).
