Multiplexer
Section Remote
Defect Indicator:
MS_RDI
The far end is detecting a major problem with the signal that this
board is transmitting.
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.
Run test board UUCSS command.
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.
If it does the problem is off-board.
If the amber LED continues to flash, replace the circuit pack; if the
error persists, escalate the problem.
20
Loss of pointer:
LOP
ATM framer chip is unable to access the payload part of the signal.
Reset the board (reset board UUCSS).
If the error persists replace the board.
21
Path Signal Error
(PSL)
(STM1/SONET)
The incoming signal payload is not set up for transmission of ATM
data.
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.
22
High-level Path
Alarm Indication
Signal:
HP_AIS
The payload is invalid.
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.
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
amber LED flash goes away.
If it does the problem is off-board.
If the amber LED continues to flash, replace the circuit pack.
