ATM-EI (Expansion Interface Circuit Pack)
Issue 1 May 2002

555-233-143
1
FAIL
The test did not detect the test tone through the loop-around 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 EPN 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 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.
If any tests fail, investigate those tests and repair the Packet Interface
circuit pack.
2. If the Packet Interface circuit pack is OK, resolve 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 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).
