Secondary Signaling Link Hardware Check (#639)

The ISDN-PRI Signaling Group D-Channel port depends on the health of the

DS1/UDS1 Interface circuit pac k 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 th ere are problems with the ISDN-PRI Secondary Signaling

Channel port (ISDN-PLK), also investigate the DS1/UDS1 circuit pac k.

See Figure 3-23 for DS1 connections, Figure 3-24 for UDS1 connections.

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 proc essor can exchange c all control message s.
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).
