Description Repair procedure
15 SYSCLOCK f ailed The boa rd is n ot loc ked to the TDM b ackp lane c loc k sign al. 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 with Error Code 16, 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. 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 more the fiber on the ATM switch side to a different port.
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 multiplex er
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.
