j. Error type 1153: the ATM connection audit found some d iscrepancy in the
firmware’s VC token numbers and live VCs. The problem is rec tified in
firmware and no action is need ed.
k. Error Type 1281: loss of high-level signal indica ting operational prob lems
of equipment located outside of the circuit p ack and the fiber c onnected
to the board. Aux Data values are listed in Table 3-65.

Description Repair procedure
15 SYSCLOCK f ailed The boa rd is n ot loc ked to t he TDM b ackp lane c lock s ignal . This is
probably due to a Tone Clock problem.
1. Check for TDM-BUS or TONE-BD errors in the Error Log.
2. If no other problems are present, reset the circuit pack (reset
board UUCSS)
16 Loss of Signal:
LOS The fiber is not connected properly to the ATM-TRK board or ATM switch (or to the multiplexer section [MUX] if present).It is possible
that the board transceivers are not functioning properly.
1. Run test board UUCSS command.
2. If Test#1259 fails, connect a fiber b ac k-to-back in a looped
mode (one strand of fiber connecting the transmit transceiver
to the receive transceiver of the board) and see if the yellow
LED flash goes away. If it does the problem is off-board.
3. If the yellow LED continues to flash, replace the circuit pack.
17 Loss of Frame:
LOF The fiber signal cannot obtain or maintain STM-1/OC-3 framing.
1. Try to move the fiber on the ATM switch side to a different port.
This may require administration on the ATM switch.
2. If the problem persists, reset the circuit pack (reset board
UUCSS).
18 Multiplexer
Section Alarm
Indication Signal:
MS_AIS
There is a major problem on the far end (between multiplexer
section [MUX] and the switch) that prohibits the circuit pac k from
sending a valid signal.
1. See if the ports at the MUX and/or the ATM switch are
connected snugly.
2. Run test board UUCSS command
3. If Test #1259 fails with Error Code 18, connect a fiber
back-to-back in a looped mod e (one strand of fiber connecting
the transmit transceiver to the receive transceiver of the board)
and see if the yellow LED flash goes away.
4. If it does the problem is off-board.
5. If the yellow LED continues to flash, replace the circuit pack; if
the error persists, escalate the problem.
