ATM-TRK (Circuit Emulation Service Circuit Pack)
Issue 5 October 2002
765
555-233-119
18 Multiplexer
Section Alarm
Indication Signal:
MS_AIS There is a major problem on the far end (between multiplexer
section [MUX] and the switch) that prohibits the circuit pack from
sending a valid signal.
See if the ports at the MUX and/or the ATM switch are connected
snugly.
Run test board UUCSS command
If Test #1259 fails with Error Code 18, 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; if the
error persists, escalate the problem.
19 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-TRK board) is the same as the ATM-TRK
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
yellow LED flash goes away.
If it does the problem is off-board.
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.
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-TRK board) is the same as the ATM-TRK
circuit pack’s cable interface.
