Expansion Interface 2-Way Transmission Test
(#241)
This test is a basic connectivity test between the two cabinets. The test first sends
a test tone from the cabinet of the Expansion Interface circuit pack under test
through the opposite Expansion Interface circuit pack to a Tone Detector in the
opposite cabinet. The connections are then reversed and the tone is passed in the
opposite direction. This test should be run once from each Expansion Interface
circuit pack on the fiber.
PASS Test tone was correctly detected after the internal Expansion
Interface loop back on both TDM Busses.
1. Refer to other Expansion Interface circuit pack tests if the
Expansion Interface Link is not functioning correctly.
0 NO
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.
