9-263ATM-TRK (Circuit Emulation Service Circuit Pack)
9
19 Multiplexer
Secti o n Remote
Defect Indicator:
MS_RDI
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-TRK board) is the same as
the ATM-TRK circuit pack’s cable interfac e
2. Run test board UUCSS command.
3. If Test #1259 fails with Error Code 19, 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.
20 Loss of pointer:
LOP ATM framer chip is unable to access the payload part of the signal.
1. Reset the board (reset board UUCSS).
2. If the error persists replace the board.
21 Path Si gnal Er ror
(PSL)
(STM1/SONET)
The incoming signal p ayload is not set up for transmissio n of ATM
data.
1. 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 interfac e.
22 High-level Path
Alarm Indication
Signal :
HP_AIS
The payload is invalid.
1. 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 interfac e.
2. Run test board UUCSS.
3. If Test #1259 fails with Error Code 22, 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.
