DS1C-BD (DS1 Converter Circuit Pack)
4. If the problem still persists, run the Far-End Fiber Optic Terminator (lightwave
transceiver) Loopback test (#789) on this DS1 converter circuit pack via test board
location long. If this test fails, replace the lightwave transceiver that is connected
to the neighbor DS1 converter circuit pack at the other end of the DS1 converter
complex. If the neighbor board is connected to the Fiber Endpoint via metallic cable,
this test aborts.
5. If the problem still persists, replace connectors and the cable between the neighbor
DS1 converter circuit pack and the Fiber Endpoint at the other end of the DS1
converter complex. The cable may be a fiber or a metallic cable.
u. Error Type 2049: Fiber Loss of Signal (LOS) alarm occurred at the other end of the DS1
converter complex. The DS1 converter circuit pack at the other end of the DS1 converter
complex does not detect a signal coming into the circuit pack from the fiber. (The neighbor
DS1 converter circuit pack detected the LOS and relayed this information to this DS1
converter circuit pack via the DS1 chel.) The amber LED will flicker at a 5-Hz rate (on for
0.1 second, off for 0.1 second).
1. Execute list fiber-link to determine the Fiber Endpoints that are connected to
both ends of this DS1 converter complex. Enter display errors and follow the
associated repair procedures for any EXP-INTF (Expansion Interface Circuit Pack) or
SNI-BD (SNI Circuit Pack) errors for the Fiber Endpoints that are administered on this
fiber link, and Enter display errors and follow the associated repair procedures for
any FIBER-LK (Fiber Link) errors for this fiber link.
2. If the problem still persists, run the Far-End DS1 converter circuit pack loopback test
(#788) on this DS1 converter circuit pack via test board location long. This
test shows if the neighbor DS1 converter circuit pack hardware is functioning. If this
test fails, replace the DS1 converter circuit pack at the other end of the DS1 converter
complex.
3. If the problem still persists, run the Far-End Fiber Optic Terminator (lightwave
transceiver) Loopback test (#789) on this DS1 converter circuit pack via test board
location long. If this test fails, replace the lightwave transceiver that is connected
to the neighbor DS1 converter 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
converter circuit pack and the Fiber Endpoint at the other end of the DS1 converter
complex. The cable may be fiber or metallic.
v. Error Type 3329: This error indicates that excessive slips have occurred on the fiber link
between the DS1 converter board and the Fiber Endpoint. See SYNC (Port Network
Synchronization) for diagnosing slip problems.
