Secondary Signaling Link Hardware Check (#639)
The ISDN-PRI Signaling Group D-Channel port depends on the health of the
DS1/UDS1 Interface circuit pack on which it resides. This test will fail if there are
problems with either the ISDN-PRI Primary D-channel port or the DS1/ UDS1
circuit pack. If there are problems with the ISDN-PRI Secondary Signaling
Channel port (ISDN-LNK or ISDN-PLK), also investigate the DS1/UDS1 circuit
pack.
1113 ABORT The Signaling Link is down. Therefore no messages can be sent to
the Far-end switch.
1. Examine the results of Tests #636 and #639 and fol low
recommendations provided there.
2. If either test passes, it may be because the signaling link was
disabled by system technician. Verify this by using the d isplay
comm link command. Tests #636 and #639 pass if the
signaling link is not enabled.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2500 ABORT Same as ABORT with no error code.
1. Follow the recommendations for ABORT with no error code.
2500 FAIL Same as ABORT w ith no error code.
1. Follow the recommendations for ABORT with no error code.
PASS A message was composed and sent to the Far-end switch. The
ISDN PRI specification allows up to two minutes for a reply.
1. Check the Error Log for ISDN-SGR (ISDN-PRI Signaling Group )
for errors of type 2305 for evidence of a Remote Layer 3 Query
failure. If no new errors were logged since this test was run, then
this switch and the Far-end switch processor can exchange call
control messages.
2. If there is still a problem with a particular DS1 ISDN Trunk or PRI
Endpoint Port (B-channel), busyout the trunk or port and run the
long test sequence, paying particular attention to the results of
Test #258 (ISDN Test Call).
