Communication Manager Maintenance Object Repair Procedures
1. Enter display errors and follow the associated repair procedures for any SYNC,
TDM-CLK, and SNC-BD errors.
2. Verify that the DS1 facility and the network are using the same Line Coding. For TN574
boards and TN1654 boards in T1 mode, also verify that the Framing Mode used is the
same. Use list fiber-link and display fiber-link to check the values for this
DS1 facility. Contact T1 Network Service to check the modes used by the network. See
Line Coding and Framing Mode for details on how these options apply to the TN574 and
TN1654 DS1 converter boards.
3. For TN574 boards and TN1654 boards in T1 mode, check line equalization settings as
described in DS1 Converter-1 and DS1 Converter-2 Line Compensation”
4. Enter display errors and follow the associated repair procedures for any EXP-INTF,
and SNI-BD errors for the Fiber Endpoints. Enter display errors and follow the
associated repair procedures for any FIBER-LK errors for this fiber link.
5. If the problem still persists, replace this DS1 converter circuit pack.
6. If the problem still persists, replace the DS1 converter circuit pack at the other end of the
DS1 converter complex.
g. Error Type 1025: Loss of Frame Alignment (LFA) Alarm, the RED alarm. This alarm
indicates that the DS1 interface associated with the DS1 facility cannot frame up on the
received data.
For the following repair procedure, see to Figure 54: DS1 Facility Connections and the
diagrams in the related test descriptions.
1. If the network is used instead of private T1 lines, check that the DS1 facility and the
network are using the same line coding. For TN574 boards and TN1654 boards in T1
mode, also verify that the Framing Mode used is the same. For TN1654 boards, verify
that the two boards in the DS1 converter complex are using the same bit rate. Use
Llist fiber-link and display fiber-link to check the values for this DS1
facility. Contact T1 Network Service to verify the modes set for the network. See Line
Coding, Framing Mode, and Bit Rate for details on how these options apply to the TN574
and TN1654 DS1 converter boards.
2. Run the Near-End External Loopback Test (#799) via test ds1-facility location
external-loopback by setting up a loopback at CPE side of CSU towards DS1
converter circuit pack shown as loopback point LB 1 in the test description diagram. If the
test fails, replace connectors and the cables between CSU and the DS1 converter circuit
pack.
3. If the test passes, run the Near-End External Loopback Test (#799) via test
ds1-facility location external-loopback by setting up a loopback at DS1
facility side of CSU towards the DS1 converter circuit pack shown as loopback point LB 2
in the test description diagram. If the test fails, replace the CSU.
4. If Test #799 passes, run the Far-End Internal Loopback Test (#797) via test
ds1-facility location long. If Test #797 passes, go to step 6. If the test fails, run
the Near-End External Loopback Test (#799) using test ds1-facility location
