Avaya 03-300430 User Manual

m. Error Type 1537: LAN bus time out.  The circuit pack is transmitting a packet larger than 

1,024 bytes.  Replace the circuit pack.

n. Error Type 1538: A hyperactive ATM-EI circuit pack is generating an abnormal amount of 

control messages to the processor.  When this error is generated, the system automatically 
resets the ATM-EI.

1. Enter reset board location for this ATM-EI circuit pack.
2. If the same error persists, replace the ATM-EI circuit pack.

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-EI board) is the same as the 

ATM-EI circuit pack’s cable interface.

2. Run test board location. 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 amber LED 

flash goes away.

3. If it does the problem is off-board.
4. If the amber LED continues to flash, replace the circuit pack.

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 location).

2. If the error persists, replace the board.

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.  This could require administration on the ATM switch.

6. If the error is resolved, the problem is on the ATM switch port.

Yes

service to the PN is disrupted

No

the system switches to the standby PNC
