FAIL A test failed.
● Error Code 7 - The conference test or the noise test failed.
● Error Code 13 - The reflective looparound test with gain set to
low and 600-ohm balance failed.
● Error Code 14 - The reflective looparound test with gain set to
high, using RC, balance failed.
● Error Code 15 - The nonreflective looparound test failed.
1. Disconnect the terminal equipment from the circuit pack at the
cross-connect and run the test again.
2. If the test fails again, replace the circuit pack and reconnect the
terminal equipment. If the test passes the second time, this means
the test results were affected by the terminal equipment connected
to the port. In this case, ignore the results of this test if every other
test passes or aborts and the station is operating properly. Failure
of test 47 does not cause an alarm. If there are failures of other
tests, investigate those errors. Investigate user-reported troubles
with this port by using other port tests, by examining station wiring,
and by examining the station to ensure that it is correctly translated
as off-premises or on-premises.
If the Looparound and Conference circuit 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, either the 631DB AC power unit or the
676B DC power unit may be defective. (The 631DB power unit is used in
a medium cabinet powered by an AC source. The 645B power unit is
used in a medium cabinet powered by a DC power source.) The system
may contain a TN736 or TN752 power unit circuit pack or a 631DB AC
power unit, but not both types of power units. To investigate problems
with the power unit, see RMC-ENV (Power/Fan Sensors) or CARR-POW
(Carrier Power Supply). If a red LED is lit on TN736 or TN752 power unit
circuit pack, replace the pack. If the test fails on more than 1 port, check
for errors on the TONE-BD or the TONE-PT. If errors exist, take
appropriate actions. When the tone errors are cleared, rerun the test.
