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 follow
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 display
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 with 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).
