ISDN-SGR (ISDN-PRI Signaling Group)
Primary Signaling Link Hardware Check (#636)
The ISDN-PRI Signaling Link Port itself 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.
See Figure 33
If there are problems with the ISDN-PRI Signaling Link, also investigate the
DS1/UDS1 circuit pack (DS1-BD/UDS1-BD).

Description/ Recommendation
Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
Rollabout video abort. The PRI terminal adapter associated with this
D-channel port is detached from the circuit pack. This is a normal abort
when the rollabout video feature is enabled. To complete test on this port,
either:
1. Re-attach the disconnected PRI terminal adapter and retry test
command, or
2. Disable the rollabout video feature on this circuit pack by entering
change ds1 PCSS and set the field
Endpoint Detached?
There is a problem with the DS1/UDS1 Circuit Pack, or the ISDN-PRI
Signaling Channel (D-channel). No DS1 ISDN Trunk (B-channel) or
wideband PRI Endpoint calls can be made until the problem is resolved.
1. Consult the procedures for DS1/UDS1 Circuit Pack and the ISDN-PRI
Signaling Channel (ISDN-LNK/ISDN-PLK).
The basic physical connectivity of the primary D-channel is intact and
functional. Try this test repeatedly to ensure the link is up and to uncover
any transitory problems.
