Signaling Link Board Check (#643)
This test checks the state of the UDS1 Interface circuit pack (TN464C or later)
transporting the ISDN-PRI Signaling Link.
Signaling Port Packet Bus Loopback Test (#939)
This test verifies the connectivity of an ISDN-PRI Signaling Port (D-channel)
across the Packet Bus, also known as the LAN bus. It will execute only if the port
is busied out. 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 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 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 PCCSS and set the field "Alarm when PRI Endpoint
Detached?" to "y."
8 FAIL The UDS1 circuit pack (TN464C or later) is not in-service.
1. Check the Hardware Error Log for entries logged against UDS1-BD
and consult the UDS1-BD (UDS1 Interface Circuit Pack) Maintenance
documentation for repair procedures.
PASS The UDS1 Interface circuit pack transporting the ISDN-PRI Signaling Link
Port is in-service.
