Trace Function 02; Feature Requirements - Avaya CS 1000 Maintenance Manual

Trace function 02

Call trace function 02 provides the information from the active (main) call register, the incoming
call state, and the outgoing call state (if any). Trace function 02 is intended as a debugging
tool for system designers.
The information output by function 02 includes the following:
NODE ORIG,TAND,TBD SID xxxx—system identifier RLS xx xx—release of software, issue
number of node TNS l s c u—TN of the originating set CREF xxxx—call reference number
Incoming call:
ISTATPM x—incoming state progress mark ITRKPM x—incoming trunk progress mark LOC
xxxx—call reject software location
Outgoing call:
OSTATPM x—outgoing state progress mark OTRKPM x—outgoing trunk progress mark LOC
xxxx—call reject software location
Main call register:
Word 0—MainPM/AuxPM Word 1—CRlink Word 2—Queue_In Word 3,4—Son_Types/
Processes Word 5—Aux_CRlink Word 6—OrigType/TerType Word 7—TTR_TN Word 8—

Feature requirements

Network Call Trace is limited to basic ISDN PRI/ISL calls across system private networks.
NCT collects information only during initial call setup. It does not report on further call
modification, such as Call Transfer.
Network call information is lost and the call trace ceases when any of the system nodes in
which the call is being traced is initialized or any of the D-channels fails.
Although NCT requires PRI or ISL, calls can be traced to nodes that do not support Network
Call Trace. Calls can also be traced to DTI or analog trunks. However, only the local node
information is provided. These are the trunk types that are not supported: ADM, AWU, DIC,
MDM, MUS, PAG, RAN, RLM, and RLR.
Call trace information is still output if the call is blocked before the trunk is seized. If queuing
(Ring Again, CBQ or OHQ) is available, then the original call trace function is activated when
the call is offered to the user.
