57 FAIL 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 test board location short.
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.
If the Hybrid Circuit and Conference Circuit test fails for every port on a circuit
pack, a -5 volt power problem is indicated. The AC power unit may be
defective. The system may contain a TN752 power unit circuit pack or a
631DB AC power unit, but not both types of power units. To investigate
problems with a power unit, see RMC-ENV (Power/Fan Sensors)
on
page 1951 or CARR-POW (Carrier Power Supply)
on page 770.
PASS 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.

NO
BOARD
The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board inserted, an incorrect board inserted,
or an insane board inserted.
1. Check to ensure that the board translations are correct. Enter
list config, and resolve any problems that are found.
2. If the board was found to be correctly inserted in step 1, enter busyout
board location.
3. Enter reset board location.
4. Enter release board location.
5. Enter test board location long.
This should re-establish the linkage between the internal ID and the port. If
this is not the case, dispatch to check to ensure that there is a valid board
inserted.
