Primary Signaling Link Hardware Check (#636)
The ISDN-PRI Signaling Group D-channel port depends on the health of the TN464C or higher
suffix UDS1 Interface circuit pack or MM710 DS1 Interface Media Module on which it resides.
This test will fail if there are problems with either the ISDN-PRI Primary D-channel port or the
UDS1 circuit pack or MM710 DS1 Media Module. If there are problems with the ISDN-PRI
Primary Signaling Channel port (ISDN-LNK), also investigate the UDS1 circuit pack
(UDS1-BD), or MM710 Media Module (MG-DS1).

Description / Recommendation
ABRT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1700 ABRT Rollabout video abort. The PRI terminal adapter associated with the
primary D-channel port is detached from the circuit pack or media module.
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, or
2. Enter change ds1 location to disable rollabout video on the
board, and set the Alarm when PRI Endpoint Detached field to y.
8 FAIL There is a problem with the UDS1 TN464C or higher suffix circuit pack or
the MM710 DS1 Interface Media Module, or the ISDN-PRI Signaling
Channel (D channel). No ISDN trunk or PRI endpoint calls can be made
until the problem is resolved.
1. Consult the procedures for the UDS1 TN464C or higher suffix circuit
pack (UDS1-BD), or the MM710 DS1 Interface Media Module
(MG-DS1), and the ISDN-PRI Signaling Channel (ISDN-LNK).
PASS The basic physical connectivity of the primary D channel is intact and
functional. One might try this test repeatedly to ensure the link is up and to
uncover any transitory problems.
