3 FAIL The nonreflective 1004 Hz tone test of the port failed. An echo was
detected from the port. Poor quality transmission was detected to or from
the port. The problem may be off-board.
7 The conference capabilities of the port failed. Poor quality transmission
was detected to or from the port. The problem may be off-board.
129 The reflective 404-Hz tone test failed. Poor quality transmission was
detected to or from the port. The problem may be off-board.
131 The reflective 1004-Hz tone test failed. Poor quality transmission was
detected to or from the port. The problem may be off-board.
133 The reflective 2804-Hz tone test failed. Poor quality transmission was
detected to or from the port. The problem may be off-board.
!
CAUTION:
The port may still be operational, or the fault may be off-board
(connections or CO). Off-board problems also include incoming
seizures or off-hook port seizures during the test and, perhaps
somewhat unlikely, noise induced by adjacent electric power lines.
Customers having this problem should resolve it with their local
power company to temporarily alleviate the alarm caused by the
failure of this test. The test may be disabled from trunk administration
’Test’ field. This turns off all testing for that trunk group except for
tests 6 and 36.
Proceed as follows unless power or tone problems are suspected (see
note below).
1. To make sure the problem is on-board, disconnect the port from the
far-end and retry the test. Coordinate this with the CO, or do it after
busy hours.
2. If the retry fails, replace the circuit pack.
3. If the retry passes and no troubles have been reported, disable the
test in the trunk group administration. If the retry passes and troubles
have been reported, coordinate isolation with the CO.
If the loop around and conference circuit test fails for all ports on a circuit
pack, a -5 volt power problem is indicated.
PASS DID Trunk Loop Around and Conference Test is successful. This port is
functioning properly.
1. If users are reporting troubles, examine loop connections to the port
and refer problem to the CO.
