If the alarm is off board, then either a major hardware error has occurred in
a common part of the circuit pack, or a good clock signal cannot be
recovered from the synchronization source. The synchronization source
can be the fiber link or any one of the DS1 facilities.
1. Enter display errors and follow the associated repair procedures
for any SYNC, TDM-CLK, and SNC-BD errors.
2. Enter display errors and follow the associated repair procedures
for any FIBER-LK and DS1-FAC errors.
3. If the problem persists, replace the DS1 CONV circuit pack.
b. This error indicates that the DS1 CONV circuit pack 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 switch setting on the TN1654 circuit pack does
not match the administered Bit Rate on the fiber-link form. If the on-board
switch setting is wrong, the circuit pack must be physically removed to
change the setting of the board option switch. If the administered 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 install it in its
administered slot or execute the remove fiber-link command followed by
the add fiber-link command to re-add the fiber-link setting the DS1 CONV
board’s administered location to the physically installed slot.
e. A minor hardware error has occurred in a common part of the circuit pack,
not circuit or packet specific. Replace the DS1 CONV circuit pack.
f. A major hardware problem has occurred that affects only circuit data being
received from the DS1 CONV circuit pack. Replace the DS1 CONV circuit
pack.
g. A major hardware problem has occurred that affects only circuit data being
transmitted from the DS1 CONV circuit pack. Replace the DS1 CONV
circuit pack.
h. A major hardware problem has occurred that affects only packet data being
received from the DS1 CONV circuit pack. Replace the DS1 CONV circuit
pack.
i. A major hardware problem has occurred that affects only packet data being
transmitted from the DS1 CONV circuit pack. Replace the DS1 CONV
circuit pack.
j. A major lightwave transceiver transmit error occurred that affects data
transmitted from the fiber link to the DS1 facility. Replace the DS1 CONV
circuit pack.
