FAIL The Echo Cancellation Test has failed:
● Error 1400 - Echo canceller function failed. The Echo Canceller
Function Test, which is executed by firmware, failed.
● Error 1401 - Echo canceller memory failed. The Echo Canceller
Memory Test, which is executed by firmware, failed.
Echo Cancellation is no longer being supplied by the board. Clear the
alarm using the following commands: busyout board location, test
board location long, release board location. If the test still
fails, replace the Media Module.
When this test fails, echo cancellation will be bypassed on all channels on
the board. The Media Module can still be used for a T1/E1 line interface
without echo cancellation. This capability provides limited service for the
customer until the Media Module can be replaced.
PASS The Echo Cancellation feature is functioning properly.
Any NO
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. Ensure that the board translations are correct. Execute the add ds1
location command to administer the MM710 interface if it is not
already administered.
2. If the board was already administered correctly, check the error log to
determine whether the board is hyperactive. If this is the case, the
board is shut down. Reseating the board will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then enter
the busyout board location command.
4. Enter the reset board location command.
5. Enter the release board location command.
6. Enter the test board location long command.
This should re-establish the linkage between the internal ID and the port.
