DS1 Tie Trunk Seizure Test (#136)
The DS1 Tie Trunk Seizure Test is run to verify the trunk’s signaling capability. The
test is composed of two parts. The first part queries the circuit pack for the
following errors: Loss of Signal, Red Alarm, Blue Alarm, Yellow Alarm, and
Hyperactivity Alarm. The second part of the test is performed by sending a
seizure message to the DS1 Interface circuit pack and expecting an active reply
by the DS1 Interface circuit pack. If maintenance software does not receive any
reply and the timer expires, the test fails. Once the active message is received, a
dial pause message is sent to the DS1 Interface circuit pack. If the DS1 Interface
circuit pack replies with a dial pulse tone message when the far end responds to
the seizure, then the DS1 tie trunk Seizure Test passes. If the far end does not
respond to the seizure and the timer expires, and the DS1 Interface circuit pack
sends a reorder message back to the maintenance software, then the test fails.
This second part of this test
cannot
be run on a trunk if one of the following cases
is true:
1. The trunk direction is administered as an incoming only trunk.
2. The trunk is the 24th port on a DS1 Interface circuit pack which is
administered using 24th Common Channel Signaling.
3. The trunk has been seized by a normal trunk call.
4. The trunk is administered with maintenance test disabled.
5. The outgoing signal type of the trunk is either automatic or
immediate-start.
0NO
BOARD
The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
1. Check to ensure that the board translations are correct. Use the list config
command, and resolve any problems that are found.
2. If the board was found to be correctly inserted in step 1, issue the busyout
board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board long command. This should re-establish the linkage
between the internal ID and the port. If this is not the case, check to see
that there is a valid board inserted.
