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 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.

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 interface.

2. Run test board location.

If 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 amber LED flash goes away.

●

If it does the problem is off-board.

●

If the amber 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 with reset board location.

2. If the error persists, replace the board.  

27

SIGCON_DO

WN ATM 

switch high 

level signal.

The board cannot communicate with the ATM switch.

1. Busyout the board (busyout board location).

2. Test the board (test board long location).

3. If Test #1260 fails, replace the board.
4. If Test #1260 passes, make sure the ATM address on both the 

S8700 Multi-Connect 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.
