Repair procedure
The payload is invalid.
Make sure the ATM switch port (or a MUX port, if present between
ATM switch and the ATM-TRK board) is the same as the ATM-TRK
circuit pack's cable interface.
Run test board UUCSS.
If Test #1259 fails with Error Code 22, connect a fiber back-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.
If the yellow LED continues to flash, replace the circuit pack.
The far-end is detecting a major problem with the signal that this
board is transmitting. The transmitted payload is invalid.
Make sure the ATM switch port (or a MUX port, if present between
ATM switch and the ATM-TRK board) is the same as the ATM-TRK
circuit pack's cable interface.
Run test board UUCSS command; if the Test #1259 fails with Error
Code 23, connect a fiber back-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.
If the yellow LED continues to flash, replace the circuit pack.
On board ATM framer chip is not able to frame cells based on the
cell header.
Reset the board (reset board UUCSS).
If the error persists, replace the board.
The board cannot communicate with the ATM switch.
Busyout the board (busyout board UUCSS).
Test the board (test board long UUCSS).
If Test #1260 fails, replace the board.
If Test #1260 passes, make sure the ATM address on both the
Avaya Definity Server CSI and the ATM switch sides are the same
for this board.
If the address is the same, change the port on the ATM switch side.
If the error is resolved, the problem is on the ATM switch port.
