AUX-TRK (Auxiliary Trunk)
Issue 1 June 2005 667
133 FAIL The reflective 2804-Hz tone test failed. No transmission was detected to or
from the port. The problem may be off-board.
1. To make sure the problem is on-board, disconnect the port from the
auxiliary equipment and retry test.
2. If the test fails, replace the circuit pack. Otherwise, if the test passed
after disconnecting the port from the auxiliary equipment, the problem
is off-board. Check the wiring and connections to the auxiliary
equipment and retry the test after reconnecting the port to the auxiliary
equipment. If the test fails, check the auxiliary equipment. See the
preceding procedure for a failure with Error Code 7.
Note:
Note: If the Looparound and Conference test fails for every port on a
circuit pack, a -5 Volt power problem is indicated. If a TN736 or
TN752 power unit circuit pack is present, the 631DB AC power
unit or the 676B power unit may be defective. The system may
contain either a TN736 or a TN752 power unit circuit pack OR a
631DB power unit, but not both types of power units. To
investigate power problems, see CARR-POW (Carrier Power
Supply) on page 770.
PASS Looparound and Conference test is successful. This port is functioning
properly.
