3. If the problem still persists, replace the DS1 converter circuit pack.
p. Error Type 769, Aux Data 6: A minor FOI receive error occurred that affects data received
from the DS1 facility and transmitted to the fiber link. Replace the DS1 converter circuit
pack.
q. Error Type 769, Aux Data 7: A minor on-board hardware failure exists on the processor/
control hardware on the DS1 converter circuit pack. Replace the DS1 converter circuit pack.
r. Error Type 1281: For TN574 DS1 converter boards, this error indicates that the facility
masks or the clock reference masks do not match between the two DS1 converter circuit
packs in the DS1 converter complex.
For TN1654 DS1 converter boards, this error indicates that the facility masks do not match
between the two DS1 converter circuit packs in the DS1 converter complex.
Alarm should clear in 15 minutes.
1. If the problem persists, reset both DS1 converter circuit packs in the DS1 converter
complex via reset board.
2. If the problem persists, replace this DS1 converter circuit pack.
3. If the problem persists, replace the DS1 converter circuit pack at the other end of the
DS1 converter complex.
s. Error Type 1537: The two TN574 DS1 converter circuit packs in the DS1 converter
complex do not have the same firmware vintage. The TN574 DS1 converter with the older
vintage should be replaced. This error does not apply to TN1654 boards.
t. Error Type 1793: Fiber Loss of Frame Alignment (LFA) alarm occurred at the other end of
the DS1 converter complex. The DS1 converter circuit pack at the other end of the DS1
converter complex cot frame up on the signal coming into the circuit pack from the fiber.
(The neighbor DS1 converter circuit pack detected the LFA and relayed this information to
this DS1 converter circuit pack via the DS1 control chel.) The amber LED will flicker at a
5-Hz rate (on for 0.1 second, off for 0.1 second).
1. Execute list fiber-link to determine the Fiber Endpoint that is connected to the
DS1 converter circuit pack. Enter display errors and follow the associated repair
procedures for any EXP-INTF (Expansion Interface Circuit Pack) or SNI-BD (SNI
Circuit Pack) errors for the Fiber Endpoints. Enter display errors and follow the
associated repair procedures for any FIBER-LK (Fiber Link) errors for this fiber link.
2. If the problem still persists, check for excessive slips and synchronization problems.
Enter display errors and follow the associated repair procedures for any SYNC
(Port Network Synchronization), TDM-CLK (TDM Bus Clock), and SNC-BD (Switch
Node Clock Circuit Pack) errors.
3. If the problem still persists, run the Far-End DS1 converter Circuit Pack Loopback test
(#788) on this DS1 converter circuit pack via test board location long. This
test indicates if the neighbor DS1 converter circuit pack hardware is functioning. If the
test fails, replace the DS1 converter circuit pack at the other end of the DS1 converter
complex.
