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 channel.) 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, and SNI-BD 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 errors for this fiber link.

2. If the problem still persists, run the Far-End DS1 converter circuit pack loop-back 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 MO SYNC for diagnosing 
slip problems.
