Repair procedure
The far end is detecting a major problem with the signal that this
board is transmitting.
1. Make sure the ATM switch port (or a MUX port, if present between
ATM switch and the ATM-EI board) is the same as the ATM-EI
circuit pack’s cable interface.
2. Run test board location.
3. If Test #1259 fails with Error Code 19, 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 amber LED flash goes away.
4. If it does the problem is off-board.
5. If the amber LED continues to flash, replace the circuit pack; if the
error persists, escalate the problem.
ATM framer chip is unable to access the payload part of the signal.
1. Reset the board (reset board location).
2. If the error persists replace the board.
The incoming signal payload is not set up for transmission of ATM
data.
1. Make sure the ATM switch port (or a MUX port, if present between
ATM switch and the ATM-EI board) is the same as the ATM-EI
circuit pack’s cable interface.
The payload is invalid.
1. Make sure the ATM switch port (or a MUX port, if present between
ATM switch and the ATM-EI board) is the same as the ATM-EI
circuit pack’s cable interface.
2. Run test board location.
3. 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 amber LED flash goes away.
4. If it does the problem is off-board.
5. If the amber LED continues to flash, replace the circuit pack.
