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-PLK), also investigate the DS1/UDS1 circuit pack.
See
Figure 33
for DS1 connections,
Figure 34
for UDS1 connections.

Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.

ABORT
The Secondary D-channel is not administered for this Signaling Group. This
is a NORMAL ABORT. Only a Primary D-channel must be administered for
a Signaling Group.
4
FAIL
There is a problem with the Processor Interface Link. No DS1 ISDN Trunk
(B-channel) or Wideband PRI Endpoint calls can be made until the problem
is resolved.
1. Display the Communication-Interface Links Form via the display
communication-interface command to determine which link is down
(find the one that matches the DS1 Interface circuit pack on which this
ISDN-PRI Signaling Link Port resides) and then refer to the PKT-INT
Maintenance documentation.

FAIL
There is a problem with the DS1/UDS1 Interface circuit pack or the
ISDN-PRI Secondary Signaling channel (D-channel). No ISDN Trunk
(B-channel) or Wideband PRI Endpoint calls can be made until the problem
is resolved.
1. Refer to the DS1/UDS1 circuit pack and the ISDN-PRI Signaling
channel (ISDN-LNK/ISDN-PLK) Maintenance documentation.
PASS
The basic physical connectivity of the Signaling Group’s Secondary
D-channel is intact and functional. Try this test repeatedly to ensure the link
is up and to uncover any transitory problems.
