Far-End Lightwave Transceiver Loopback Test (#789)
This test starts at the specified DS1 converter circuit pack location and loops at the Fiber Optic
Terminator (lightwave transceiver) that is connected to the DS1 converter circuit pack at the
other end of the DS1 converter complex. See Figure 108: Far-End Lightwave Transceiver
Loopback Test.
The test sends digital data through every DS1 facility chel. Two different test patterns are used,
these are hexadecimal values 55 and AA.
For a standard-, duplex-, or high-reliability system (no PNC duplication), this test can only be
executed at the endpoint that is closer to the server relative to the neighbor DS1 converter
circuit pack because of its impact on the system control links. The completion of the test will be
delayed in this configuration to wait for the recovery of the system control links. For a
critical-reliability system (PNC duplication), the test can be executed on any DS1 converter
circuit pack. This test runs on the DS1C-BD (DS1 Converter Circuit Pack) maintenance object.
