2 OVERVIEW
The SVI 9220 SS7 to SS7 protocol converter provides interconnect between different SS7 networks running disparate SS7 protocols. It can also provide MTP L3 and SCCP routing functionalities as well as allowing for transport of SS7 between NGN IP networks and traditional TDM networks.
2.1 SS7 INTERCONNECT The SVI 9220 product series terminate the SS7 signalling directly on the unit via the SS7 signalling interface boards over TDM or can provide SS7 over IP connectivity via SIGTRAN. When connecting direct over TDM via the interface boards the low layer SS7 protocols are terminated directly on the unit. When interfacing using SIGTRAN the system uses the M3UA/M2UA or M2PA adaptation layer to provide SS7 interconnect.
2.1.1 PROTOCOL SUPPORT
The SVI soft switch can support many different protocol variants. The following table provides a list of protocols that the SVI can support. A full list is maintained on the Squire web site.
Protocols ETSI ISUP V1, V2, V3 ITUT ISUP Blue Book, White Book SSUTR2 BTNUP (IUP) UK ISUP TUP Blue Book ANSI ISUP SCCP Country Variants Swiss, Mexican, Pakistan, Chinese, contact

2.1.2 TERMINATING AND NON TERMINATING VOICE SUPPORT
The SVI allows when inter working between two distinct protocols the ability to act as a signalling engine only for circuit based protocols. This reduces the requirement for the number of E1/T1 trunks to be terminated on the unit. A direct relationship is formed between the two interconnecting circuits of two different networks. This arrangement is especially useful for injecting additional traffic into a network without the need to allocate a separate point code for the interconnect.
2.2 CALL CONTROL FUNCTIONALITY The SVI switch adds a number of call control routing options enabling the user to control the flow of calls and the call information across the system. The following provides an overview of some of these functions
Routing on called party number Routing on calling party number Routing on incoming network circuit. Called and Calling party digits and associated information
manipulation. White List, Black List functionality. Protocol information manipulation. Reattempt on failure
2.3 MTP LAYER 3 ROUTING FUNCTIONALITY The SVI 9220 provides the ability to route SS7 messages at MTP Layer 3 depending on the SS7 routing label. The outgoing routing label can then be changed allowing for translation of the routing label and expansion of an incoming linkset to multiple outgoing linksets. The matching and routing functionality includes
Match on OPC, DPC, NI, CIC, SIO and Originating linkset Over writing on OPC, DPC,NI and CIC Specifying outgoing primary and secondary linksets.
2.4 SSCP ROUTING FUNCTIONALITY The SVI 9220 provides the ability to route SS7 messages at the SCCP layer depending on the SCCP routing label. The outgoing SCCP routing label can then be

3 INSTALLATION
3.1 PRE-CONFIGURATION If a pre-installation checklist had been provided to Squire Technologies before shipment the unit will have be configured to the pre-installation checklist. As long as the pre-installation list was correct the unit can be plugged and played into the network without any configuration requirements. If the pre-configuration checklist was not provided or the checklist was not complete or incorrect the unit will need to be configured before the system will operate correctly.
3.2 PRE INSTALLATION On delivery of the SVIS, the system needs to be checked to ensure that all cards are seated correctly in the PCI chassis. The SVIS contains components that can be damaged by electrostatic discharge. Anti-static procedures should be followed at all times, when handling components of the SVIS.

3.4 POWER The chassis is supplied with either single or dual hot swap power supplies. The power supplies are rated at either 110/240 Volts AC or 48 Volts DC. Check that the correct power supply has been provided. The Power Supply will auto-sense the power connected and adjust accordingly. There are two power switches on the 1U chassis, the main power supply switch is at the rear of the unit above the power cord, and a toggle switch on the front panel of the unit. On activation of the rear power switch if power is connected correctly the power switch will illuminate and the system will start up. If the system does not power up hold down the toggle button on the front of the unit for 1-2 seconds. The unit should now power up. If after this the unit still does not power up check the power lead and power supply, otherwise contact Squire support.
3.5 POWER ON SELF TESTS. When the system powers up it performs a number of self tests, these tests take up to 1 minute from power up. The system becomes available after these tests.
3.6 EARTHING It is important the power supply is correctly earthed. Failure to do this may result in system failure. There is an additional earth point provided on the rear of the chassis which Squire Technologies recommend is used.
3.7 CONNECTING ETHERNET CABLE If the system is connected to a standard network hub then a straight through network cable should be used. If the cable is connected directly to an IP device then a cross over network cable should be used. If the network cable is connected correctly a green light will activate on the Ethernet socket on the chassis. If this does not activate then check that both ends of the Ethernet cable is connected and also check that the cable is correctly wired and working. The unit is shipped with an IP address of 192.168.2.100 with a net mask of 255.255.255.0. To check that the IP is functioning OK run a ping test to the machines IP address on a (windows DOS session type ping 192.168.2.100 at the command prompt).
3.8 MONITOR, KEYBOARD AND MOUSE ACCESS The system does not generally require a monitor, keyboard and mouse but standard monitors, keyboards and mice can be connected to the system if required.

4 SYSTEM OPERATION
The SVIS systems have a fully onboard automated maintenance system that automatically brings the system into service on power up. The system continuously monitors the status of the connecting network interfaces and reacts appropriately to loss of signalling and bearer interfaces, maintaining system bandwidth and operation even under failure conditions. This section describes how to gain access to the unit if required for general maintenance operations.
4.1 OPERATING SYSTEM The SVIS runs on PC technology using Red Hat Linux as the core operating system.
4.2 DIRECTORY/FILE STRUCTURE The following major files are located on the systems hard drive.
File Location Description sswitch /home/squire Main switch program Dbase.cfg /home/squire System configuration file gw /etc/init.d Switch start up script Gateway_DD-MM-YY /home/squire Debug file
4.3 ACCESSING LINUX TERMINAL COMMAND LINE. All system commands described within this document use the terminal command line interface. This allows for commonality across different versions of Linux and also allows for remote access of the unit through a telnet session.
4.3.1 CONNECTING LOCALLY
The SVIS is provided with standard PC monitor, mouse and keyboard inputs allowing for local connection and control of the system. The monitor must be capable of supporting a display resolution of at least 1024*768. When the system has booted the user will be asked to enter a username and password. The system is supplied with the root (administrator) account setup with the following user name and password and a user account called squire.
Username Password root squire
squire squire Enter the user name and password at the prompt and the main Red Hat GUI will start up.

4.3.3.1 Manual Pages To display more information about the above commands and their options use the man command followed by the command for which more information is required, man pwd
4.4 STARTUP When the system is powered up the switch will automatically attempt to bring into service the switch. The switch is run as a daemon at power up using the standard Linux init process, which runs the gw start-up script.
4.4.1 CONTROLLING AUTOMATIC STARTUP
To check the status of the gw script, use the chkconfig command. On the command line, type the following [root@localhost/root]/sbin/chkconfig --list This will display all current scripts controlled by the init process. If the gw script is present and started at power up, then the following line will be included in the output from the chkconfig command. [root@localhost/root]/sbin/chkconfig list gw 0:off 1:off 2:off 3:on 4:on 5:on 6:off [root@localhost/root] If the script is present but not started at power up the following will be displayed [root@localhost/root]/sbin/chkconfig list gw 0:off 1:off 2:off 3:off 4:off 5:off 6:off [root@localhost/root]
4.4.1.1 Stopping Automatic Startup To stop automatic startup the following is typed at the command line [root@localhost/root]/sbin/chkconfig gw off
4.4.1.2 Starting Automatic Startup To start automatic startup the following is typed at the command line [root@localhost/root]/sbin/chkconfig gw on

5 SYSTEM RESOURCES
The SVIS controls all aspects of the system by abstracting the system down to a number of resources. These resources are further divided into sub resource types that describe the operation of a given resource. There are a number of instances of a given resource and each resource has a number of configurable attributes. These resources are used to allow the administrator to configure and maintain the system. The following table shows the list of resources used within the system.
Resource Types Description System Entire System Driver NS700 Driver Driver instance describes and controls
the SS7 signalling cards. Card NS700 Card The SS7 signalling interface card Interface SS7 Interface

All of these resources are arranged into a parent-child hierarchical arrangement. The following diagram shows the relationship between the main resources within the system. The maintenance module within the system uses these associations to determine the behaviour of a resource. The SVI maintenance system starts from the top of the tree and works its way down the hierarchical tree starting each resource one by one. A resource can only be started to be brought into service when its parent is in service (for example a signalling link is only attempted to be started when its Interface cable is in service). If when running a system a given resource does not come into service the user can look back at the resources parents to see which resources are not in service providing a speedy way of debugging a system.

6 CONFIGURATION
The configuration of the system is read on start up from an ASCII flat file called Dbase.cfg, located in directory /home/squire. This configuration file populates the systems database which is held in volatile RAM. When the system is running the configuration of the system can be changed by using the OA&M telnet connection provided into the system. This section describes the configuration which can be applied for both the ASCII flat file and through the OA&M Telnet port.
6.1 CONFIGURATION FILE SYNTAX The syntax for the configuration file is shown below
6.1.1 RESOURCE
The resource field contains the name of the resource that is to be configured. See section System Resources for full resource definition.
6.1.2 INSTANCE RANGE
The instance range contains the instance of the resource that is to be configured. This field can take a range of instance i.e. 1-3.
6.1.3 ATTRIBUTE
The attribute field is the attribute of the resource that is to be configured. These are described for each resource within this section.
6.1.4 VALUE
This field contains the value of the attribute. This may be a text string, number or range of numbers. If the value is a number the H prefix can be used to describe the number in a hexadecimal number, i.e. H10
6.1.5 COMMENT
To comment out a line in the ASCII text file the * character is used.

7 SS7 CONFIGURATION
7.1 INTRODUCTION If you are new to SS7 it may be helpful to read Appendix B SS7 Network Overview. The SVI can terminate SS7 signalling using various methods.
Using an onboard signalling-only card Using a third-party Signalling Gateway.
The type of SS7 termination will determine the SS7 configuration required.
7.1.1 PCM INTERCONNECT
The SS7 board handles the SS7 signalling. The SVI must be configured for the full SS7 interconnect from MTPL2 upwards. Any bearer channels that are associated on the terminating PCMs are drop and inserted across to the corresponding E1 on the other SS7 switch.
7.1.2 SIGTRAN INTERCONNECT
On a SIGTRAN interconnect the signalling PCMS are terminated on a third party SS7 signalling gateway and the SS7 information is backhauled over IP using the SCTP protocol to the SVI. The SVI currently supports M3UA, M2UA and M2PA adaptation layers.

7.2 CONFIGURING TDM INTERCONNECT
7.2.1 CONFIGURING THE SS7 INTERFACE CARD
The 4 port SS7 interface card provides the signalling and PCM termination for connection into the SS7 network. The system will be supplied with a minimum of 1 SS7 card, however it may be necessary to deploy additional cards for additional signalling links or PCM termination. To set up the card the following resources need to be configured
Driver Card Interface Timing Priority
The following diagram shows the physical association between the three main resources driver, card and interface. From this diagram it can be easily seen how quickly additional cards can be added to the system to enable additional signalling or PCM bandwidth.

7.2.2 SETTING UP THE SS7 SYSTEM TIMING
7.2.2.1 System Synchronisation All circuit switched digital telephony networks need to be fully synchronised against a common clock. This synchronisation is also referred to as timing. When a systems timing is synchronised all PCMS will be running at the same frequency and with in the same phase. To achieve this a system derives its clock from a single timing source. This source is either from the clock provided on a given PCM or from an internal clock running on a particular interface card. This source clocks timing is then distributed to all other PCMs on the system. This method ensures system synchronisation with the network. If the system is not synchronised to the network then PCM alignment and speech problems will occur. In nearly all cases the SoftSwitch will be synchronising its timing off the SS7 network.
7.2.2.2 Multiple Card Synchronisation If multiple SS7 cards are within a system one card will be responsible for sourcing the synchronisation clock. The remaining cards will synchronise their interfaces form the Telephony bus that connects all of the interface cards together. In a multiple card arrangement the card that derives the timing is called the Primary Master Clock and the remaining cards that drive their PCMS from this clock are called Slaves. The following examples show possible timing scenarios and provides examples of the configuration file syntax. Example 1

7.2.3 TIMING FAIL OVER
If the synchronisation source port on the Master card fails for any reason, the whole system will become unstable because there is no timing source. To prevent this the system can set up a list of alternative timing source PCMs which the system on failure of the main timing source, will switch to and source the synchronisation clock from. These alternative timing sources can be located on either a Master or Slave Card. The following shows how to achieve a configuration of two clock sources, one on interface 0 which is on card 0 port 0 and one on interface 4 which is card 1 port 0. Timing Priority 0 Status Start Timing Priority 0 Interface 0 Timing Priority 1 Status Start Timing Priority 1 Interface 4 On start up the system will always try to attempt to source the synchronisation clock from the Card resource configuration, however if one of the alternative timing sources comes into service first the system will source the timing off this interface.
7.2.4 HANDLING VOICE CIRCUITS ON SIGNALLING PCMS, TSMAP RESOURCE
SS7 allows for the signalling PCM to also carry bearer (voice) channels as well. Any bearer traffic that is present on the terminating PCMS on the system need to be hard wired between the two SS7 networks. This is achieved by setting up a number of timeslot cross connects on the signalling board. This enables PCM timeslots on network A to be connected directly to the associated PCM timeslot on network B. The TSMap resource is used to setup these cross connects on the system
