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-b oard problems inc lude incoming seiz ures
or off-hook port seizures d uring the test and, perhaps, noise indu ced
by adjacent electric power lines. The test may be disab led 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 see if 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 are
reported, co ordinate isolation with the CO.
NOTE:
If the loop around and conference circuit test fails for all ports on a
circuit pack, a -5 volt power problem is indic ated. A power unit may
be defective (CARR-POW). If the test fails on more than 1 port, check
for errors on the TONE-BD or the TONE-PT maintenance objects.
4. Rerun the test.
PASS DID Trunk Looparound 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.
