1 FAIL The test did not detect the test tone through the looparound connection.
NOTE:
The packet portion of this test was not run since the circuit portion
failed.
1. Test the active Tone/Clock (test tone-clock UUCSS) on the PN that
contains the defective ATM-EI circuit pack to verify that dial tone is
being supplied.
2. If the Tone/Clock is healthy, test the ATM-EI circuit pack (test board
UUCSS long).
3. If this test continues to fail, replace the ATM-EI circuit pack or
transceiver.
4. Test the new ATM-EI circuit pack (test board UUCSS long).
2 FAIL The test tone was transmitted and detected correctly, but the correc t
data packet was not detected b y the Packet Interface circuit pack.
1. Test the Packet Interface circuit pack to verify that it is functioning
properly. If any tests fail, investigate those tests and repair the
Packet Interface circuit pack.
2. If the Packet Interfac e circuit pack is OK, re solve any DS1 CONV-BD
alarms or errors (if so equipped).
3. Test the ATM-EI circuit pack (test board UUCSS long).
4. If this test continues to fail, replace the ATM-EI board.
5. Test the new ATM-EI circuit pack (test board UUCSS long).
3 FAIL The test tone was transmitted correctly, but the returned tone was
distorted.
1. If the Tone/Clock is healthy, test the ATM-EI circuit pack (test board
UUCSS long).
2. If this test continues to fail, replace the ATM-EI circuit pack.
3. Test the new ATM-EI circuit pack (test board UUCSS long).
4 FAIL Unable to create loop for TDM path for this test.
1. Retry the command at 1-minute intervals a maximum of 3 times.
2. If this test continues to fail, replace the ATM-EI circuit pack.
3. Test the new ATM-EI circuit pack (test board UUCSS long).
