System Technician-Demanded T ests: Descripti ons
and Error Codes
The command to test the ISDN-LNK MO is test port UUCSSpp where pp is 24 f or
24-channel interfaces and 16 for 32-c hannel interfaces.
Signaling Link Board Check (#643)
This test checks the health of the TN464C/D UDS1 Interface transp orting the
ISDN-PRI Signaling Link Port
Signaling Port LAN Loopback Test (#939)
This test is destructive.
This test verifies the connectivity of an ISDN-PRI signaling p ort (D-channel)
across the LAN bus, also known as the pac ket bus. It will execute only if the port
is out-of-service. Failure of this test indicates a f ault associated with the port
hardware on the circuit pac k.

Result Description/ Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals for a maximum of 5 times.
1700 ABORT Rollabout v ideo abort. The PRI terminal adapter asso ciated with this D-ch annel
port is detached from the circuit pac k. This is normal when the rollabout video
feature is enabled. To complete a test on this port:
1. Re-attach the disconnected PRI terminal adapter
2. Disable the rollabout video feature on this board by entering change ds1
UUCSS and set the ‘‘Alarm when PRI Endpoint Detached?’’ field to ‘‘y.’’
8 FAIL The UDS1 TN464C/D circuit pack is not in-service.
1. Check the Hardw are Error Log for entries logged against UDS1-BD, and
consult “UDS1-BD” for repair procedures.
PASS The UDS1 Interface circuit pack transporting the ISDN-PRI Signaling Link Port
is in-service.
