DS1 CONV-BD

DS1 CONV circuit pack hardware is functioning. If this test fails,
replace the DS1 CONV circuit pack at the other end of the DS1
CONV complex.
3. If the problem still persists, run the Far-End Fiber Optic Terminator
(lightwave transceiver) Loopback test (#789) on this DS1 CONV
circuit pack via the test board UUCSS long command. If this test
fails, replace the lightwave transceiver that is connected to the
neighbor DS1 CONV circuit pack. (If the neighbor board is
connected to the Fiber Endpoint via metallic cable, then this test will
abort.)
4. If the problem persists, replace connectors and the cable between
the neighbor DS1 CONV circuit pack and the Fiber Endpoint at the
other end of the DS1 CONV complex. The cable may be fiber or
metallic.
u. This error indicates that excessive slips have occurred on the fiber link
between the DS1 CONV board and the Fiber Endpoint. See MO SYNC for
diagnosing slip problems.
System Technician-Demanded Tests:
Descriptions And Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the Failure Audit for example, you may also clear
errors generated from other tests in the testing sequence. Tests 788 and 789 are
executed by the TN574 DS1 Converter circuit pack only.
NOTE:
Test #984 is not an actual demand maintenance test. This test number is
used to report results of the clear firmware-counters command. Refer to
the table for Test #949 to interpret ABORT codes for Test #984.
