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 on the PN that contains the defective EI circuit
pack to verify that dial tone is being supplied.
2. If the Tone-Clock is healthy, issue the test board UUCSS long on the EI
circuit pack.
3. If this test continues to fail, replace the EI circuit pack or transceiver. Then
reissue the test board UUCSS long on the new EI circuit pack.
2 FAIL The test tone was transmitted and detected correctly, but the correct data
packet was not detected by the TN1655 Packet Interface circuit pack.
1. Test the TN1655 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 checks out OK, enter display errors
and display alarms and resolve any SNI-BD and FIBER-LK alarms or
errors (Center Stage Switch only) and DS1 CONV-BD alarms or errors (if
present).
3. Issue the test board UUCSS long command on the EI board.
4. If test #242 continues to fail, replace the EI board. Then issue the test
board UUCSS long command on the new EI board.
5. If test #242 continues to fail, replace the lightwave transceiver, reset the
circuit pack and issue the test board UUCSS long command on the EI
circuit pack.
