9-179ATM-EI (Expansion Interface Circuit Pack)
9
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.
23 High-level path
Remote defect
Indicator: HP_RDI
The far-end is detecting a major problem with the signal that this
board is transmitting. The transmitted 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 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.
3. If it does the problem is off-board.
4. If the yellow LED continues to flash, replace the circuit pack.
24 Loss of cell
delineation (LCD) On board ATM framer chip is not able to frame cells based on the
cell header.
1. Reset the board (reset board UUCSS).
2. If the error persist s, replace the board .
27 SIGCON_DOWN
ATM switch high
level signal.
The board cannot co mmunicate with the ATM switch.
1. Busyout the board (busyout board UUCSS).
2. Test the board (test board long UUCSS).
3. If Test#1260 fails, replace the board.
4. If Test #1260 passes, make sure the ATM address on both the
DEFINITY and the ATM switch sides are the same for this
board.
5. If the address is the same, change the port on the ATM switch
side.
6. If the error is resolved, the problem is on the ATM switch port.
