DS1 CO Dial Tone Seizure Test (#314)
DS1 CO Dial Tone Seizure test checks the trunk’s signaling capability provided by
the DS1 Interface circuit pack. The maintenance software initiates the test by
sending a “seizure” message to the DS1 Interface circuit pack and expects an
“active” reply from the DS1 interface circuit pack. If the “active” message is
received, then the test passes. If no message is received and the timer expires,
the test is aborted. If the DS1 Interface circuit pack sends a “reorder” message
back to maintenance software, then the test fails.
This test cannot be run on a trunk in any of the following conditions:
a. The trunk direction is administered as an incoming only trunk.
b. The trunk has been seized by a normal trunk call.
c. The trunk is administered with maintenance test disabled.

Description / Recommendation
ABORT
Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1000
ABORT
System resources required to run this test are not available. The port may be
in use on a valid call. Use the status trunk command to determine when the
port is available for testing.
1004
ABORT
The port has been seized by a user for a valid call. Use the status trunk
command to determine when the port is available for testing.
1. Retry the command at 1-minute intervals up to 5 times.
1005
ABORT
Test failed due to incompatible configuration administered in trunk group form.
1. Look at the trunk group administration form and see if the trunk is incoming
only, port 24 on a DS1 Interface with common control-channel signaling, or
an automatic CO type such as FX. Under any of these conditions this is a
normal abort.
1018
ABORT
Test has been disabled via administration.
1. Verify that the
Maintenance Tests
field on the Trunk Group Form is
set to n. To enable the test, issue the change trunk-group x command
where “x” equals the number of the trunk group to be tested. Then change
the entry in the
Maintenance Tests
field on the form to y.
2. Repeat the test.
1020
ABORT
The DS1 Interface circuit pack is out-of-service.
1. Look for UDS1-BD errors in the Hardware Error Log. If present, see
‘‘UDS1-BD (UDS1 Interface Circuit Pack)’’ on page 8-1707
.
2. Retry the command.
