Does anyone know of any type of CCS Trace log reader that's available out there? Using the Maintenance Command CCS TRACE ENABLE CONTINOUS is fine, but on a busy system, there is a lot of data to try to capture and sift through.

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
up.

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 GROUP

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.

Call Not Connected
Normal call from 822300 D.Sykes to 832400 G.Rodgers. 832400 did not answer and
822300 hung up.

Explanation of trace:
The first two lines are the same as the first example showing the calling and called
extension. Extension 832400 does not answer so there is no CCM message.
Extension 822300 (PABX A) clears down the call followed by B.
Examples Of Other Call Types
822300 calls 832400 who is busy. 822300 hangs up.

Supplementary Information String Parameters
PARAMETER
NAME
DESCRIPTION AND CODING
ACCOUNT CODE This Parameter comprises-a sequence of IA5 numeric
characters representing an account code.
ALARM LEVEL The Alarm Level shall always contain an IA5 numeric character in the
range 0-4, optionally followed by an IA5 alpha character.
The first character shall be used as follows:
Value Name Description
0 None No alarms currently active in the system
1 Low Some alarms active, but no effect on traffic
handling
2 Medium Some alarms active which do have an effect on
traffic handling, but the PBX can still function
3 High Alarms active in the system are such that the
PBX operation is greatly affected
4 Alarm
reporting
inhibited
No alarm information shall be provided because
maintenance personnel on site have inhibited the
reporting of alarms
The precise details of when each category is used is dependent upon the
PBX design.
The optional alpha character shall be the letter "P" to indicate that the
mains power supply has failed. If this is not present it shall be assumed
that power is available.
A PARTY
ADDRESS
In general the A Party Address is a digit sequence that represents the
address of the originating caller. The precise meaning of the A Party
Address 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 is
that digit sequence which, when used as a DPNSS 1 Destination Address
by any PBX in the network, will cause a call to be routed to the originating
extension or operator.
When the A Party is CLC-ISDN, then the A Party Address shall be a
sequence of digits that, if sent as a destination address to the public
network via an access at the Gateway PBX where the call crossed the
public network boundary, would cause a call to be routed via the public
network to that party. In the case of an ETS 300 102 access, the digit
sequence shall be that which would be associated with Numbering Plan
Identification and Type of Number, "Unknown".
Depending on the type of number (e.g. local or national) and the topology
of the private network, an A Party Address associated with CLC-ISDN may
also be valid at other public network accesses. It is therefore
recommended that an A Party Address sent by a PBX should have the
widest possible significance throughout the private network. For example,
in the case of a private network within the UK, the full national number
including the 11011 prefix should be used.
NOTE: Before it can form a DPNSS 1 Destination Address, an A Party
SX-2000/3300 ICP CCS Trace

PARAMETER
NAME
DESCRIPTION AND CODING
Address associated with CLC-ISDN may need to be prefixed with digits to
cause routing to a Gateway PBX.
When the A Party is CLC-MF5 then the meaning of the A Party Address
depends upon the numbering plan employed by the private network:
- if the DPNSS 1
and SSMF5 parts of the network share a global numbering plan then the A
Party Address is that digit sequence which, when used as a Destination
Address in a DPNSS ISRM, will cause a call to be routed to the originating
SSMF5 extension;
A PARTY
ADDRESS
(CONTINUED)
- if the DPNSS 1 and SSMF5 parts of the network have separate
numbering 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 the
originating SSMF5 extension (NOTE: Under these circumstances when
the A Party Address is used as a Destination Address in a DPNSS 1
ISRM, it must be prefixed in order first to route the call to the SSMF5
Gateway).
When the A Party is CLC-PSTN or CLC-DEC the address of the calling
party will not be available. Some PBXs conforming to earlier versions of
the BTNR may use the A Party Address Parameter to convey the Trunk
Number. No standardised method of coding the Trunk Number is
specified; 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 = 5892
would be encoded as: *50*5892#
BEARER
CAPABILITY
This Parameter comprises a sequence of IA5 characters representing the
values of octets 3, onwards of an ISDN Bearer Capability information
element, using 3B4I encoding (see APPENDIX 1 to this Annex).
example: The following Bearer Capability information element:
Octet 1: identifier
Octet 2: length
Octet 3: 10010000
Octet 4: 10010000
Octet 5: 10100011
would be encoded as: *233*dIBc#
B PARTY
ADDRESS
In general the B Party Address is a digit sequence that represents the
address of the second party in a call, e.g. the originally called party in the
case of Diversion. The precise meaning of the B Party Address Parameter
is subject to the CLC of the second party.
When the B Party is CLC-OPD or CLC-OP then the B Party Address is
that digit sequence which, when used as a DPNSS 1 Destination Address
by any PBX in the network, will cause a call to be routed to the associated
extension or operator.
When the B Party is CLC-ISDN, then the B Party Address shall be a
sequence of digits that, if sent as a destination address to the public
network via an access at the Gateway PBX where the call crossed the

network to that party. In the case of an ETS 300 102 access, the digit
sequence shall be that which would be associated with Numbering Plan
Identification and Type of Number, "Unknown".
Depending on the type of number (e.g. local or national) and the topology
of the private network, a B Party Address associated with CLC-ISDN may
also be valid at other public network accesses. It is therefore
recommended that a B Party Address sent by a PBX should have the
widest possible significance throughout the private network. For example,
in the case of a private network within the UK, the full national number
including the "0"prefix should be used.
NOTE: Before it can form a DPNSS 1 Destination Address, a B Party
Address associated with CLC-ISDN may need to be prefixed with digits to
cause routing to a Gateway PBX.
When the B Party is CLC-MF5 then the meaning of the B Party Address
depends upon the numbering plan employed by the private network:
- if the DPNSS 1
and SSMF5 parts of the network share a global numbering plan then the B
Party Address is that digit sequence which, when used as a Destination
Address in a DPNSS ISRM, will cause a call to be routed to the called
SSMF5 extension;
B PARTY
ADDRESS
(CONTINUED)
- if the DPNSS 1 and SSMF5 parts of the network have separate

when sent via an SSMF5 route, will cause a call to be routed to the
originating SSMF5 extension (NOTE: Under these circumstances when
the B Party Address is used as a Destination Address in a DPNSS 1
ISRM, it must be prefixed in order first to route the call to the SSMF5
Gateway).
When the B Party is CLC-PSTN or CLC-DEC the address of the called
party will not be available. Some PBXs conforming to earlier versions of
the BTNR may use the B Party Address Parameter to convey the Trunk
Number. No standardised method of coding the Trunk Number is specified
and 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#
BREAKDOWN
CAPABILITY
LEVEL
This Parameter is used to set the capability level of a call which may be
used to breakdown an existing call.
The Parameter comprises a decimal number coded as up to two IA5
numeric characters in the Range 0-15.
BREAKDOWN
PROTECTION
LEVEL
This Parameter is used to set the protection level of a call to guard against
subsequent attempts made to break down the call.
The Parameter comprises a decimal number coded as up to two IA5
numeric characters in the Range 0-15.
BUSY SERVICES This Parameter has been renamed "SERVICES".

NUMBER
That digit sequence which, when used as a Destination Address will cause
routing back to the PBX which has requested route optimisation and, on
arrival at that PBX, identifies the call being optimised.
CAUSE This Parameter comprises a sequence of IA5 characters representing the
values of octets 3, onwards of an ISDN Cause information element, using
3B4I encoding (see APPENDIX 1 to this Annex)
example: The following Cause information element:
Octet 1: identifier
Octet 2: length
Octet 3: 10000000
Octet 4: 10010000
would be encoded as: 234`I@#
CHANNEL
NUMBER
This Parameter is used to identify a specific traffic channel.
The Channel Number is encoded as its 5-bit binary equivalent but is
transmitted as an IA5 character in accordance with the following table.
On receipt of this Parameter the Terminating PBX discards bits 6 and 7 of
the IA5 character and uses the remaining 5 bits to identify the Channel
Number as in the following table.
