Recovery

1. Enter the following command to determine the status of the clock:
   rept-stat-clk

   The output indicates how many cards are using the specified clock, and how many cards are reporting fault with the specified clock.

   Following is an example of the possible output:

   tekelecstp 00-04-23 13:34:15 EST EAGLE 35.0.0
       CARD LOC= 1114 (Active   )    CARD LOC= 1116 (Isolated )
       PRIMARY BITS   = Active       PRIMARY BITS   = -----
       SECONDARY BITS = Idle         SECONDARY BITS = -----
                                     PST           SST       AST
       SYSTEM CLOCK                  IS-NR         ACTIVE    ALMINH 
       # Cards using CLK A = 009     # Cards with bad CLK A = 000
       # Cards using CLK B = 000     # Cards with bad CLK B = 009
       # Cards using CLK I = 000
       Command Completed.

   Caution:

   Resetting, reseating, or replacing a LIM will cause both links on the card to fail. If the card is a LIM, place the links on the LIM out of service by entering the dact-slk command.
2. If only one card is reporting fault, reset the card.
3. If the fault has not cleared, reseat the card.
4. If the fault has not cleared, replace the card.
   Refer to the Maintenance Manual for card removal/replacement procedures.
5. If the fault has not cleared, replace the TDM card in MASP A.
6. If more than one card is reporting fault with the designated clock, check the clock cable connection at the shelf backplane (refer to the Installation Manual for cable location).
   If the clock cable is at fault, replace the clock cable.
7. If the fault has cleared and any of these cards are LIMs, place the links assigned to these cards back into service using the act-slk command.
