ATM-EI (Expansion Interface Circuit Pack)
Table 8-91. ATM Board Framer Loop-Around Test (#1260) — Continued
Error Test
Code Result Description / Recommendation
1 FAIL The test did not detect the test tone through the loop-around connection.
1. Test the active Tone-Clock (test tone-clock UUCSS) on the EPN that
2. If the Tone-Clock is healthy, test the ATM-EI circuit pack (test board
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 correct data
packet was not detected by the Packet Interface circuit pack.
1. Test the Packet Interface circuit pack to verify that it is functioning properly.
2. If the Packet Interface circuit pack is OK, resolve any DS1 CONV-BD
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
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 up to 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).
5 FAIL Unable to create loop for packet path for this test.
1. Retry the command at 1-minute intervals up to 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).
