Q.93B (Network) Layer
Are connection requests being received by A500 Call Control?
1. Enter show signaling stats port q93b (or the port of interest) on the A500
console. Screen 5-29 shows the screen output.
Screen 5-29. A500:show signaling stats A1.2 q93b
NOTE:
If there is no connection between the TN230X and the A500 at the
Q93B protocol layer, then no report displays.
Ensure that the fields have the values indicated below.
2. If connections are being rejected, the
Last Cause Code
may give a clue
to why. The Cause Code ( Table 5-10 on page 5-93 below) indicating the
error may be on the PPN port even though the EPN port is the one
misbehaving, and vice versa.
Port A1.2
(or the port of
interest)
If this field is
not configured for UNI
signaling , then the port was administered for no
UNI signaling (admin link). Use show signaling
summary to verify that
Signaling is UNI3.1 .

These counters should be non-zero if the A500 is
handling Q.93B protocol layer messages sent by the
PPN and EPN. They may not increase during
troubleshooting unless calls are being made, since the
PPN initially sets up control connections to the PPN
and then sets up talk path connections as needed.
