Primary Signaling Link Hardware Check (#636)
The ISDN-PRI Signaling Link Port itself depends on the health of the DS1/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 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).

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
