DS1 CONV-BD
n. If the alarm is on board, then a minor FOI transmit error occurred that
affects data transmitted from the fiber link to the DS1 facility. Replace the
DS1 CONV circuit pack.
If the alarm is off board, then either a minor FOI transmit error occurred that
affects data transmitted from the fiber link to the DS1 facility. or corrupted
packets are being received from the packet facility.
1. Enter display errors and follow the associated repair procedures
2. If the problem persists enter display errors and follow the
3. If the problem still persists, replace the DS1 CONV circuit pack.
o. A minor FOI receive error occurred that affects data received from the DS1
facility and transmitted to the fiber link. Replace the DS1 CONV circuit
pack.
p. A minor on-board hardware failure exists on the processor/control
hardware on the DS1 CONV circuit pack. Replace the DS1 CONV circuit
pack.
q. For TN574 DS1 CONV boards, this error indicates that the facility masks or
the clock reference masks do not match between the two DS1 CONV
circuit packs in the DS1 CONV complex.
For TN1654 DS1 CONV boards, this error indicates that the facility masks
do not match between the two DS1 CONV circuit packs in the DS1 CONV
complex.
Alarm should clear in 15 minutes.
1. If the problem persists, reset both DS1 CONV circuit packs in the
2. If the problem persists, replace this DS1 CONV circuit pack.
3. If the problem persists, replace the DS1 CONV circuit pack at the
r. The two TN574 DS1 CONV circuit packs in the DS1 CONV complex do not
have the same firmware vintage. The TN574 DS1 CONV with the older
vintage should be replaced. This error does not apply to TN1654 boards.
s. Fiber Loss of Frame Alignment (LFA) 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 cannot frame up on the signal coming into the
circuit pack from the fiber. (The neighbor DS1 CONV circuit pack detected
the LFA and relayed this information to this DS1 CONV circuit pack via the
DS1 control channel.) The amber LED will flicker at a 5-Hz rate (on for
0.1 second, off for 0.1 second).
