Hybrid Line Local Digital Loop Around Test (#58)
This test checks the control channel between the SPE and the port’s digital
circuitry. The SPE sends transparent data to the on-board microprocessor and
compares the data echoed back. This test is repeated three times.
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.
0NO
BOARD
The test could not relate the internal ID to the port (no
board). This could be due to incorrect translations, no
board is inserted, an incorrect board is inserted, or an
insane board is inserted.
1. Check to ensure that the board translations are
correct. Use the list config command, and resolve
any problems that are found.
2. If the board was found to be correctly inserted in
step 1, issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board long command. 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.
