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.
4. 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 at the other end of the DS1 CONV
Complex. (If the neighbor board is connected to the Fiber Endpoint
via metallic cable, then this test will abort.)
5. If the problem still 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 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 signal coming into the circuit pack from
the fiber. (The neighbor DS1 CONV circuit pack detected the LOS and
relayed this information to this DS1 CONV circuit pack 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 Endpoints
that are connected to both 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 procedures for any FIBER-LK errors for this
fiber link.
2. If the problem still persists, run the Far-end DS1 CONV Circuit Pack
Loopback test #788 on this DS1 CONV circuit pack via the
test
board UUCSS long
command. This test will show if the neighbor
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.
