Interpreting DISPCALL output 5-3
procedure LINE_SETUP_PROCESSOR calls NIL_PROCESSOR. This
procedure call indicates that the line setup processor cannot determine how
to route the call to the terminating agent. This information indicates that the
terminating agent is invalid. Therefore, procedure NIL_PROCESSOR calls
CALLERROR, which causes the call to die.
Log Report AUD103 is generated when a process has been terminated. The
process identifier shown in field PROC of AUD103 is the same process
identifier given in field PROCID of the SWERR. This association verifies
that the procedure call to CALLERROR is the source of the call death.
Log Report AUD433 identifies the node and terminal number of the calling
DN. This information can be used with the SAVETID command, if
troubleshooting requires that other calls be made from the originating DN,
or with other tools, such as PMIST.
Log Report AUD395 and AUD398 can be used in conjunction with
DISPCALL.
In Figure 5-1 on page 5-2, the call identifier (CALLID) referred to in the
log reports is 820001. This CALLID also identifies call information
displayed with DISPCALL.
If the user processes the SHOW CALL command in DISPCALL and
specifies H as the formatting parameter (refer to SHOW on page 3-19), the
user displays the call death in a format nearly identical to Log Reports
AUD395 and AUD398. Refer to Figure 5-2 on page 5-4 for the
hexadecimal output for CALLID 820001.
Since the hexadecimal dump of the CCB and the CDB is not easy to
interpret, the DISPCALL user can dump the information on a call in
symbolic form. Refer to Figure 5-3 on page 5-5 for the formatted output
for CALLID 820001.
Notice that the Call Data Block Routing Block (CDBRTEB) in Figure 5-3
on page 5-5 contains the fields GROUP_CPID and TERMINAL_CPID,
which verify that the terminating agent was a Transmission Test Trunk
(TTT), which is an invalid terminating agent.
