Descriptions and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. For example, by clearing error codes associated with the
Primary Signaling Link Hardware check (#636), you may also clear errors
generated from other tests in the testing sequence.
Primary Signaling Link Hardware Check (#636)
The ISDN-PRI Signaling Group D-channel port depends on the health of the
TN464C/D 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 UDS1
circuit pack. If there are problems with the ISDN-PRI Primary Signaling Channel
port (ISDN-LNK), also investigate the UDS1 circuit pack (UDS1-BD).

Result Description / Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1700 ABORT Rollabout video abort. The PRI terminal adapter associated with the primary
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, or
Disable the rollabout video feature on this board by entering change ds1
UUCSS and set field ‘‘Alarm when PRI Endpoint Detached?’’ to ‘‘y.’’
8 FAIL There is a problem with the UDS1 TN464C/D circuit pack 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/D circuit pack (UDS1-BD)
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.
