5.4 Monitoring IBM 9783
This section deals with the monitoring of IBM 9783.
5.4.1 Tracing a Call
Use the procedures in this section to trace a call through the route to its
destination.
1. Observe the accumulated statistic of the voice port under test:
SHOW PERFORMANCE CALL_PROCESSING VOICE < upa>
2. Originate a call from the voice port under test.
5.4.1.1 Voice Port Statistics
1. Observe the change in statistic of the voice port under test:
SHOW PERFORMANCE CALL_PROCESSING VOICE < upa>
2. The Seize Attempts field should have incremented by one.
3. Verify that the digit sequence is being properly reported in the Dial Digits field.
4. The Setup Sent field should have incremented by one. If not, recheck the
configuration of the Destination Match rule.
5. Verify that the Outbound Attempts field increments for each call attempted.
Observe any other changes in the statistics in order to uncover the result of
the call attempts.
6. Check the Release Cause, paying particular attention to whether there are any
incremental changes in the following fields: Release No Local Bandwidth,
Release No Rmt Bandwidth, Release Channel Busy, Release Outbound Trans
Failed, Release Remote VFAX Busy, and so on.
5.4.1.2 Checking a Remote Problem
If the voice port statistics indicate no local problem, but rather suggest a remote
problem, such as Release No Rmt Bndwth or Release Remote VFAX Busy:
1. Go to the next node and observe the changes in the circuit statistics for each
call attempted:
SHOW PERFORMANCE CALL_PROCESSING CIRCUIT< group#> < circuit#>
2. If this is a terminating node, verify that the Seize Attempts field increments for
each call attempted.
3. If this is a pass-through node, verify that the Pass-Thru Attempts field
increments. Observe any other changes in statistics that would help uncover
the result of the call attempts.
4. See the next section for more information on the call processing statistics.
5.4.2 Using Statistics Command
The IBM 9783 provides statistics commands to aid in evaluating call processing
performance. The following sections provide information on these commands.
5.4.2.1 Call Processing Voice Statistics
The SHOW PERFORMANCE CALL_PROCESSING VOICE < upa#> command provides useful
call statistics information such as the causes for failure (the reason a call cannot
