1401 FAIL Echo Canceller Function failed, this could be a hardware problem
on the TN464GP/TN2464BP:
1. Issue the busyout board command.
2. Issue the reset board command.
3. Issue the test board long command.
4. Issue the release busy board command.
5. If the test still fails replace the TN464GP/TN2464BP.
PASS DS1 signal is present and the physical link is healthy. In addition,
no Integrated CSU/Sync Splitter errors or echo cancellation errors
are detected.
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. Ensure that the board translations are correct. Execute the
add ds1 UUCSS command to administer the UDS1 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
issue the busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and
the port.
