2. Enter display errors and follow the associated repair p rocedures
for any FIBER-LK and DS1-FAC errors.
3. If the problem persists, rep lace the DS1 CONV circuit pack.
b. This error indicates that the DS1 CONV circuit pa ck has been busied out
via the busyout board command. To resolve this error, release the DS1
CONV circuit pack via the release board command.
c. The 24/32-channel option switc h setting on the TN1654 circuit pa ck does
not match the administered Bit Rate on the fib er-link form. If the on-board
switch setting is wrong, the c ircuit pack must b e physically removed to
change the setting of the b oard option switch. If the ad ministered bit rate
is wrong, use the change fiber-link command to correct it.
d. The DS1 CONV board is physically installed in a slot different than its
administered slot. Remove the DS1 CONV board and inst all it in its
administered slot or execute the remove fiber-link command followed by
the add fiber-link c ommand to re-add the fiber-link setting the DS1 CONV
board’s administered l ocation to the physically installed slot.
e. A minor hardware error has occurred in a common part of the circuit p ack,
not circuit or pack et specific. Replace the DS1 CONV circu it pack.
f. A major hardware problem has oc curred that affects only c ircuit data
being received f rom the DS1 CONV circuit pack. Replace the DS1 CONV
circuit pack.
g. A major hardware prob lem has occurred that affects only c ircuit data
being transmitted from the DS1 CONV circuit p ack. Replace the DS1
CONV circuit pack.
h. A major hardware problem has oc curred that affects only p acket data
being received f rom the DS1 CONV circuit pack. Replace the DS1 CONV
circuit pack.
i. A major hardware problem has oc curred that affects only p acket data
being transmitted from the DS1 CONV circuit p ack. Replace the DS1
CONV circuit pack.
j. A major lightwave transceiver transmit error oc curred that affects data
transmitted from the fiber link to the DS1 facility. Replace the DS1 CONV
circuit pack.
k.
This error only applies to TN574 DS1 CONV circuit pack s
.
If the alarm is on board, then a minor hard ware problem has occ urred that
affects only circuit d ata being received from the DS1 CONV circu it pack.
Replace the DS1 CONV circuit pac k.
If the alarm is off board, then either a minor hard ware problem has
occurred that affects only circuit data being received into the DS1 CONV
circuit pack or a good clock sig nal cannot be recovered from one of the
DS1 facilities.
1. Enter display errors and follow the associated repair p rocedures
for any SYNC, TDM-CLK, and SNC-BD errors.
