Remote Layer 3 Query (#637)
This test will query the far-end switch or terminal adapter to determine if the
signaling connection is functioning properly at Layer 3. It will select a B-channel
in the in-service or maintenance service state and send an ISDN Layer 3
SERVice message, which requires a response from the far end (similar to
performing Test #256 on an ISDN trunk. The test will not be performed if there are
no B-channels in an appropriate ISDN service state (as when none are
administered or they are all out of service).

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:
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

FAIL
There is a problem with the Processor Interface Link. No DS1 ISDN
Trunk (B-channel) or wideband PRI Endpoint calls can be made
until the problem is resolved.

PASS
The basic physical connectivity of the primary D-channel is intact
and functional. Try this test repeatedly to ensure the link is up and
to uncover any transitory problems.
