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 DS1C-BD
alarms or errors (if present).
3. Enter test board location long on the EI board.
4. If Test #242 continues to fail, replace the EI board. Then enter test
board location long for the new EI board.
5. If Test #242 continues to fail, replace the lightwave transceiver, reset
the circuit pack and enter test board location long on the EI
circuit pack.
PASS When this test (#242) and the EI Local Looparound test (#240) pass, this
indicates that the EI board is functioning properly, but it does not verify that
the optical portion of the lightwave transceiver is functioning.
1. Enter test board location on the EI board on both ends of fiber. If
this test passes from both sides, but other tests fail, such as #241, this
condition indicates either a faulty lightwave transceiver or the fiber itself
has failed. To determine whether a lightwave transceiver or the fiber
itself has failed, execute the EI Manual Loop-Back procedure described
in a previous section.
Test #242 can only be run from both EIs if they are the standby pair and
the active pair is working properly.
2. If this EI board is failing other tests, execute the EI Manual Loop-Back
Tes t.
3. If problems still exist after the EI Manual Loop-Back Procedure
indicates both EI boards and both lightwave transceivers are healthy,
manually check out the building fiber. Verify that each optical fiber
connects to a transmitter at one end and a receiver at the other.
