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 loopback 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 loopback data on each TDM Bus. Since
this loopback is internal to the circuit pack, this test does not interfere with the
normal fiber data stream.

Result
NO No board was detected by the test.
BOARD
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.
