Table 290. TEST #57 Hybrid Circuit and Conference Circuit Test — Continued
Error Test
Code Result
7 FAIL
57 FAIL
PASS
555-233-119
Description/ Recommendation
Conference Test failed. User may be able to use conference circuit without
difficulty in some cases. In other extreme cases, conference calling will be
totally restricted.
The failure may be due to off-board circumstances, the most common of
which is an off-hook occurring during the test. Also, check the error logs
against the GPTD-BD, the TONE-BD, and the TONE-PT.
1. This error can be caused by a disconnected terminal. First, ensure that
the terminal is connected and the wiring is OK.
2. Then, issue the display port and the status station commands to
determine if the station is idle. If it is idle, issue the test port command
for this port.
3. If test continues to fail, issue the busyout port and the release port
commands, and then retest the port.
4. It is possible that the port may still be functional from a user's point of
view.
Hybrid Circuit Test failed. This could result in noisy or bad connections.
1. This error can be caused by a disconnected terminal. First, ensure that
the terminal is connected and the wiring is OK.
2. Run circuit pack tests to check the Tone Generator circuit pack and the
Tone Detector circuit pack using the test board PCSS short
command.
3. Resolve any problems that are detected on the Tone Generator circuit
pack or Tone Detector circuit pack.
4. If the Tone Generator and Tone Detector circuit packs are functioning
properly, and the test still fails, replace the Hybrid Line circuit pack.
NOTE:
If the Hybrid Circuit and Conference Circuit Test fails for all ports on a
circuit pack, a -5 volt power problem is indicated.
Hybrid Circuit and Conference Circuit Test passed. The hybrid circuitry is
transmitting properly.
1. If complaints still exist, investigate by using other port tests, and by
examining the station, wiring, and connections.
