5-90 Issue 4 May 2002
Q.SAAL (Data Link) Layer
Are ATM signaling messages reaching A500 Call Control?
1. Enter show signaling stats port qsaal on the A500 console. Screen 5-28
on page 5-90 shows the screen output.
Screen 5-28. A500: show signaling stats a1.2 qsaal screen
NOTE:
If there is no connection between the TN230X and the A500 at the Q.SAAL
protocol layer, then no report is displayed.
— If Port A1.2 (or the port of interest) is not configured for
UNI signaling, then the port was administered for no UNI
signaling (admin link command). Use the show signaling
summary command to verify that Signaling is UNI3.1.
— The Supported only for UNI 3.0 line for the SDP PDUs:
field means that the port was administered for UNI3.0 signaling
(admin link command). Use the show signaling summary
command to verify that Signaling is UNI3.1.
— The POLL PDUs and STAT PDUs counters should be increasing if
the TN230X is actively sending and receiving Q.SAAL Protocol Data
Units with the A500. This occurs even if the TN230X did not achieve
board insertion.
