System Technician-Demanded Tests: Descriptions
and Error Codes
The command to test the ISDN-LNK MO is
test port
UUCSSpp where pp is 24 for
24-channel interfaces and 16 for 32-channel interfaces.
Signaling Link Board Check (#643)
This test checks the health of the TN464C/D UDS1 Interface transporting 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 port (D-channel)
across the LAN bus, also known as the packet bus. It will execute only if the port
is out-of-service. Failure of this test indicates a fault associated with the port
hardware on the circuit pack.

Result Description/ Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals for a maximum of 5 times.
1700 ABORT Rollabout video abort. The PRI terminal adapter associated with this D-channel
port is detached from the circuit pack. 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 Hardware 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.
