Expansion Interface Local Loop Around Test
(#240)
This test is similar to the Lightwave Transceiver Loop Around Test described in
Test #242. A test tone from TDM Bus A is received by the Expansion Interface
circuit pack under test, but is not transmitted out to the lightwave transceiver
before being looped back onto TDM Bus A again. The test is then repeated using
TDM Bus B. Thus, this loop back test is performed on each TDM Bus on the
network containing the Expansion Interface circuit pack to verify that the
Expansion Interface circuit pack is able to loop back data on each TDM Bus.
Since this loop back is internal to the circuit pack, this test does not interfere with
the normal fiber data stream.
0NO
BOARD
No board was detected by the test.
1. Check the error log for wrong board (error 125) or no board
(error 131). Resolve either of these issues, if applicable.
2. Check that the board is properly translated and inserted. If so,
check for hyperactivity (error 1538). If hyperactive, use the
reset board PCSS command.
3. Run the test again. If it fails, the ID chip on board may be bad.
Replace the board and retest.
