Primary Signaling Link Hardware Check (#636)
The ISDN-PRI Signaling Link Port itself depends on the health of the DS1/UDS1
Interface circuit p ack on which it resides. This test will fail if there are p roblems
with either the ISDN-PRI Primary D-channel port or the DS1/UDS1 circuit pack.
See Figure 3-23 for DS1 connections, Figure 3-24 for UDS1 connections.
If there are problems with the ISDN-PRI Signaling Link, also investigate the
DS1/UDS1 circuit pack (DS1-BD/UDS1-BD).

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 p ack. 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 PCSS and set the field Alarm when PRI Endpoint
Detached? to y.
