DS1 CONV circuit pack hardware is func tioning. If this test fails,
replace the DS1 CONV circuit pac k at the other end of the DS1
CONV Complex.
4. If the problem still persists, run the Far-end Fiber Optic Terminator
(lightwave transceiver) Loopb ack test #789 on this DS1 CONV
circuit pack vi a the test board UUCSS long command. If this test
fails, replace the lightwave tran sceiver that is connected to the
neighbor DS1 CONV circuit pac k at the other end of the DS1 CONV
Complex. (If the neighbor b oard is connected to the Fiber Endpoint
via metallic cable, then th is test will abort.)
5. If the problem still persis ts, replace connec tors and the cable
between the neighbor DS1 CONV circuit p ack and the Fiber
Endpoint at the other end of the DS1 CONV Complex. The cab le
may be a fiber or a metallic cable.
t. Fiber Loss of Signal (LOS) alarm occurred at the other end of the DS1
CONV Complex. The DS1 CONV circuit pack at the other end of the DS1
CONV Complex does not detect a sig nal coming into the circ uit pack from
the fiber. (The neighbor DS1 CONV circuit p ack detected the LO S and
relayed this information to this DS1 CONV circuit p ack via the DS1
Channel.) The yellow LED will flicker at a 5 Hz rate (on for 100 mS, off for
100 mS).
1. Execute the list fibers command to determine the Fiber Endpoint s
that are connected to b oth ends of this DS1 CONV 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 p rocedures for any FIBER-LK errors for this
fiber link.
2. If the problem still persists, run the Far-end DS 1 CON V Circuit Pack
Loopback test #788 on this DS1 CONV circ uit pack via the test
board UUCSS long command. This test will show if the neig hbor
DS1 CONV circuit pack hardware is func tioning. If this test fails,
replace the DS1 CONV circuit pac k at the other end of the DS1
CONV Complex.
3. If the problem still persists, run the Far-end Fiber Optic Terminator
(lightwave transceiver) Loopb ack test #789 on this DS1 CONV
circuit pack vi a the test board UUCSS long command. If this test
fails, replace the lightwave tran sceiver that is connected to the
neighbor DS1 CONV circuit pack. (If the neighbor board is
connected to the Fiber Endp oint via metallic cab le, then this test
will abort.)
4. If the problem persists, rep lace 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 f iber or
metallic.
