CCS Trace Command

The CCS Trace command is used to interrogate the status of a Common Channel

Signalling link and provides an analysis of any Common Channel Signalling

messaging.

The CCS Trace command is entered from the Maintenance Terminal as follows:

CCS TRACE ENABLE

CCS Trace is enabled, monitoring the Signalling Channel. To view the results you

must first disable CCS Trace and then us the ‘CCS Trace show output command.

CCS TRACE DISABLE

CCS Trace is disabled, monitoring stops.

CCS TRACE SHOW OUTPUT

The results of the CCS Trace are displayed on the screen.

CCS TRACE ENABLE CONTINUOUS

CCS Trace is enabled and continuously monitors the signalling channel, results

are displayed in real time on the screen.

CCS TRACE SHOW CONTEXT

Displays which channels are active for CCS tracing.

CCS TRACE SET CONTEXT <PLID> -

Activates the specific channel for testing.

CCS TRACE SET CONTEXT VIRTUAL <PLID>

Activates the specific virtual channel for testing.

CCS TRACE CLEAR CONTINUOUS

Resets channels to ALL for tracing.

CCS Trace Examples

The following examples are typical of calls on DPNSS links between two SX-2000’s.

They do not show all the possible combinations of call types, call terminations

(rejected calls etc) because of the amount of information that is presented. You

should refer to the BTNR 188 documents in the Appendices for complete information.

Normally Connected Call

Normal call from 822300 D.Sykes to 832400 G.Rodgers. 832400 answered and hung

1 - RO130 This is a Real Call (R), Outgoing (O) and B Channel 130 was used.

2 - DPN DPNSS protocol used. DAS would mean DASSII. Note, on the SX-2000 and

3300 ICP Euro ISDN PRI calls will show as DPN.

3 – 2B Length of the message in hexadecimal

4 - ISRM_C Initial Service Request Message Complete. This is the information about

the call sent from A to B. C (Complete) means it is less than 45 characters. There will

be no more ISRM’s sent. If the message is longer than 45 characters there will be an

ISRM_I (incomplete) instead which will be followed by SSRM_C – Supplementary

Service Request Message Complete or an SSRM_I until the message has been sent.

5 - ;10; Service Indicator Code. The semicolons enclosing the number means it is a

binary encoded message. The value 10 means speech. Other values could be A0 for

64K data.

6 - *1*1# Supplementary Information String Identifier (SIS). The * shows the beginning

of the string, 1 is the value. It is normally followed by a # to indicate the end. In this

case it is followed by another * meaning the String has a Parameter. The section

BTNR 188 Supplementary Information String Identifiers gives a full list of the strings

and section BTNR 188 – Coding of Supplementary Information String Parameters

gives information about the Parameters. In this example, the first *1 String means

Calling/Called Line Category = Ordinary, in other words a normal extension call. The

parameter is the Service Marking showing 1 = PSTN Barred (the calling extension is

barred from dialling the PSTN).

Below are extracts from both BTNR documents showing the String Identifier value 1

and Parameter ‘Service Marking’ value 1 = PSTN barred.

4 = DISTRIBUTED GROUP5 = UNABLE TO INITIATE CLEARING AFTER ANSWER (Note)

7 - *50*822300# Second Supplementary Information String Identifier. *50 is the

Identifier (* marks the beginning). There is no # but another * indicating a string

parameter follows. 50 means Originating Line Identity/Called Line Identity (from BTNR

188 Supplementary Information String Identifiers). The string parameter 822300 is the

extension number of the calling party. So this basically means that 822300 made the

call.

8 - *100*D.Sykes# Third Supplementary Information String Identifier (again with * at

the beginning, the second * shows a string parameter follows). 100 means Text

Display and the parameter (D.Sykes) is the text value, in this case the name on

calling extension 822300.

9 – *19*Z# Fourth Supplementary Information String Identifier (again with * at the

beginning, the second * shows a string parameter follows). 19 means ‘loop avoidance’

and the parameter is either “Number of further alternative routes” or “Number of

further transits”. From the Coding of Supplementary String Parameters the value Z

indicates 25. In other words a further 25 ‘hops’ (26 is the maximum allowed). The

hops can be set in the SX-2000/3300 trunk programming. This value shows it is has

not been changed from default.

832400 Destination Address. There are no more Supplemental String Identifiers (they

would be shown with a * prefix) so the final information is the Called Party, in this case

extension 822401.

CCM 0101 CALL CONNECTED MESSAGE - indicates to theoriginating PBX that call has been connected

CIM 1000 CLEAR INDICATION MESSAGE - acknowledges CRMconfirming traffic channel free.

CRM 1000 CLEAR REQUEST MESSAGE - initiates the call clearingsequence. Always provides reason for clearing.

ISRM(C) 0000 INITIAL SERVICE REQUEST MESSAGE (COMPLETE)- defines call type and destination address – Messagelength >45 characters. ISRM(C) will not be followed byany subsequent request messages.

ISRM(I) 0001 INITIAL SERVICE REQUEST MESSAGE(INCOMPLETE) - replaces ISRM(C) when initialmessage exceeds 45 characters or when the requiredinformation is not available. ISRM(I) is likely to befollowed by Supplementary Service Request Message(s)

NAM 1001 NUMBER ACKNOWLEDGEMENT MESSAGE - confirmsreceipt of sufficient digits to process call. May bequalified with further info (e.g. Divert On Busy to .. etc)

NIM 0110 NETWORK INFORMATION MESSAGE - provides theoriginating PBX with notification of the call routingprogress. If sent this message always precedes NAM

RM(C) 0010 RECALL MESSAGE (COMPLETE) - used to establish asecond call (eg Enquiry/Conf) via the same trafficchannel as an existing call. Not supported by PlesseyISDX.

RM(I) 0011 RECALL MESSAGE (INCOMPLETE) - replaces RM(C)in same way that ISRM(I) replaces ISRM(C). Likely to befollowed by at least one SSRM. Not supported byPlessey ISDX.

RRM 1010 RECALL REJECTION MESSAGE - indicates failure ofrecall request. Reason for rejection also given.

SSRM(C) 1100 SUPPLEMENTARY REQUEST MESSAGE(COMPLETE) - concludes service request by providingall the info. Additional to ISRM(I)

SSRM(I) 1011 SUPPLEMENTARY REQUEST MESSAGE(INCOMPLETE) - replaces SSRM(C) when initialmessage exceeds 45 characters or when the requiredinformation is not available. SSRM(I) is likely to be

cover access to the public ISDN in general (see BTNR 189-I) and the CLC has

consequently been renamed as CLC-ISDN. The Status Parameter has also been

expanded to allow the additional optional Parameter "ISDN Type" to be used to

Supplementary Information String Parameters

PARAMETERNAME

DESCRIPTION AND CODING

ACCOUNT CODE This Parameter comprises-a sequence of IA5 numericcharacters representing an account code.

ALARM LEVEL The Alarm Level shall always contain an IA5 numeric character in therange 0-4, optionally followed by an IA5 alpha character.The first character shall be used as follows:

Value Name Description0 None No alarms currently active in the system1 Low Some alarms active, but no effect on traffic

handling2 Medium Some alarms active which do have an effect on

traffic handling, but the PBX can still function3 High Alarms active in the system are such that the

PBX operation is greatly affected4 Alarm

reportinginhibited

No alarm information shall be provided becausemaintenance personnel on site have inhibited thereporting of alarms

The precise details of when each category is used is dependent upon thePBX design.The optional alpha character shall be the letter "P" to indicate that themains power supply has failed. If this is not present it shall be assumedthat power is available.

A PARTYADDRESS

In general the A Party Address is a digit sequence that represents theaddress of the originating caller. The precise meaning of the A PartyAddress Parameter is subject to the CLC of the calling party.When the A Party is CLC-ORD or CLC-OP then the A Party Address isthat digit sequence which, when used as a DPNSS 1 Destination Addressby any PBX in the network, will cause a call to be routed to the originatingextension or operator.When the A Party is CLC-ISDN, then the A Party Address shall be asequence of digits that, if sent as a destination address to the publicnetwork via an access at the Gateway PBX where the call crossed thepublic network boundary, would cause a call to be routed via the publicnetwork to that party. In the case of an ETS 300 102 access, the digitsequence shall be that which would be associated with Numbering PlanIdentification and Type of Number, "Unknown".Depending on the type of number (e.g. local or national) and the topologyof the private network, an A Party Address associated with CLC-ISDN mayalso be valid at other public network accesses. It is thereforerecommended that an A Party Address sent by a PBX should have thewidest possible significance throughout the private network. For example,in the case of a private network within the UK, the full national numberincluding the 11011 prefix should be used.NOTE: Before it can form a DPNSS 1 Destination Address, an A Party


Page - 32

PARAMETERNAME


Address associated with CLC-ISDN may need to be prefixed with digits tocause routing to a Gateway PBX.When the A Party is CLC-MF5 then the meaning of the A Party Addressdepends upon the numbering plan employed by the private network:

- if the DPNSS 1and SSMF5 parts of the network share a global numbering plan then the AParty Address is that digit sequence which, when used as a DestinationAddress in a DPNSS ISRM, will cause a call to be routed to the originatingSSMF5 extension;

A PARTYADDRESS(CONTINUED)

- if the DPNSS 1 and SSMF5 parts of the network have separatenumbering plans then the A Party Address is that digit sequence which,when sent via an SSMF5 route, will cause a call to be routed to theoriginating SSMF5 extension (NOTE: Under these circumstances whenthe A Party Address is used as a Destination Address in a DPNSS 1ISRM, it must be prefixed in order first to route the call to the SSMF5Gateway).When the A Party is CLC-PSTN or CLC-DEC the address of the callingparty will not be available. Some PBXs conforming to earlier versions ofthe BTNR may use the A Party Address Parameter to convey the TrunkNumber. No standardised method of coding the Trunk Number isspecified; this has to be mutually agreed at network configuration.The A Party Address comprises a sequence of IA5 numeric characters,each in the range 0-9. The numbers are sent most significant first.example: Originating Line Identity = 5892would be encoded as: *50*5892#

BEARERCAPABILITY

This Parameter comprises a sequence of IA5 characters representing thevalues of octets 3, onwards of an ISDN Bearer Capability informationelement, using 3B4I encoding (see APPENDIX 1 to this Annex).example: The following Bearer Capability information element:Octet 1: identifierOctet 2: lengthOctet 3: 10010000Octet 4: 10010000Octet 5: 10100011would be encoded as: *233*dIBc#

B PARTYADDRESS

In general the B Party Address is a digit sequence that represents theaddress of the second party in a call, e.g. the originally called party in thecase of Diversion. The precise meaning of the B Party Address Parameteris subject to the CLC of the second party.When the B Party is CLC-OPD or CLC-OP then the B Party Address isthat digit sequence which, when used as a DPNSS 1 Destination Addressby any PBX in the network, will cause a call to be routed to the associatedextension or operator.When the B Party is CLC-ISDN, then the B Party Address shall be asequence of digits that, if sent as a destination address to the publicnetwork via an access at the Gateway PBX where the call crossed the

public network boundary, would cause a call to be routed via the publicnetwork to that party. In the case of an ETS 300 102 access, the digitsequence shall be that which would be associated with Numbering PlanIdentification and Type of Number, "Unknown".Depending on the type of number (e.g. local or national) and the topologyof the private network, a B Party Address associated with CLC-ISDN mayalso be valid at other public network accesses. It is thereforerecommended that a B Party Address sent by a PBX should have thewidest possible significance throughout the private network. For example,in the case of a private network within the UK, the full national numberincluding the "0"prefix should be used.NOTE: Before it can form a DPNSS 1 Destination Address, a B PartyAddress associated with CLC-ISDN may need to be prefixed with digits tocause routing to a Gateway PBX.When the B Party is CLC-MF5 then the meaning of the B Party Addressdepends upon the numbering plan employed by the private network:

- if the DPNSS 1and SSMF5 parts of the network share a global numbering plan then the BParty Address is that digit sequence which, when used as a DestinationAddress in a DPNSS ISRM, will cause a call to be routed to the calledSSMF5 extension;

B PARTYADDRESS(CONTINUED)

- if the DPNSS 1 and SSMF5 parts of the network have separatenumbering plans then the B Party Address is that digit sequence which,when sent via an SSMF5 route, will cause a call to be routed to theoriginating SSMF5 extension (NOTE: Under these circumstances whenthe B Party Address is used as a Destination Address in a DPNSS 1ISRM, it must be prefixed in order first to route the call to the SSMF5Gateway).When the B Party is CLC-PSTN or CLC-DEC the address of the calledparty will not be available. Some PBXs conforming to earlier versions ofthe BTNR may use the B Party Address Parameter to convey the TrunkNumber. No standardised method of coding the Trunk Number is specifiedand this has to be mutually agreed at network configuration.The B Party Address comprises a sequence of IA5 numeric characters,each in the range 0-9. The numbers are sent most significant first.

example: Diverting from address 1212 on busy.would be encoded as: *38F*1212#

Parameter values 2 and 4 are applicable and ISDN Interface explicitlyidentified as ETS 300 102.Where the same value occurs more than once, it shall be treated by thereceiving PBX as if the value appeared only once.where the values 2 and 3 appear together, the value 3 shall be ignored.The values 1 and 4 should not be considered contradictory, as the value 1refers to the DDI characteristics of the trunk whenever it is used incoming,whereas the value 4 refers to the direction of use of the trunk on thecurrent call.For the purposes of supplying and interpreting the value 3, Answer shouldbe considered as the sending or receiving of a valid CCM irrespective ofwhether it contains the String SIM-A. A trunk should be considered able toRelease only if a Release signal is guaranteed by a normal event (e.g. atimeout or user action). If Release is possible (e.g. via a maintenanceaction) but not guaranteed under normal operation, the trunk should beconsidered as unable to Release.Once a particular trunk has been allocated its STATUS Parameter(s) for agiven call, that allocation shall remain fixed for the duration of that call.Values that are not recognised may be ignored and the String processedon the remainder of the Parameter values. Transit PBXs shall pass on thecomplete Parameter including the unrecognised values. If none of thevalues in the Parameter is recognised, the String shall be treated as if theParameter were missing.
