Looparound and Conference Circuit Test (#33)
This test verifies signal transmission and conferencing capabilities of a port using
404-, 1004-, and 2804-Hz tones. This is an on-board test only: each tone is
transmitted to and looped around within the port and then returned.
This test can fail due to noise induced by adjacent electric power lines. If this is
the case, the customer must resolve it with their local power company. To
temporarily alleviate an alarm caused by failure of this test, you can disable it via
the
Test
field on the trunk administration form.
2000
ABORT
Response to the test request was not received within the allowable time period.
2100
ABORT
Could not allocate the necessary system resources to run this test. This could
be due to a failure to seize the port.
1. Retry the command at 1-minute intervals up to 5 times.
Any
FAIL
This test can fail due to either on- or off-board problems. Off-board problems of
concern include EXP-PN and EXP-INTF faults, TDM-BUS faults, and faults
associated with the tone detectors/tone generators. Clear every off-board
problem before replacing the board. Keep in mind that a TDM-BUS problem is
usually the result of a faulty board connected to the backplane or bent pins on
the backplane.
1. Resolve any EXP-PN and/or EXP-INTF errors.
2. Resolve any TDM-BUS errors.
3. Resolve any TONE-BD and/or TONE-PT errors.
4. Test the board when the faults from steps 1, 2, and 3 are cleared. Replace
the board only if the test fails.
PASS
The port is correctly using its allocated time slots. User-reported troubles on
this port should be investigated using other port tests and examining station,
trunk or external wiring.
0
NO
BOARD
The test could not relate the internal ID to the port (no board).
1. Verify that the board’s translations are correct. Translate the board, if
necessary.
2. Issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board command. This should re-establish the linkage
between the internal ID and the port.
