Repair procedure
ATM-EI (Expansion Interface Circuit Pack)
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.
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.
The board cot communicate with the ATM switch.
1. Busyout the board with busyout board location.
2. Test the board with test board long location.
3. Release the board with release board long location.
4. If Test #1260 fails, replace the board.
5. If Test #1260 passes, make sure the ATM address on both the
server and the ATM switch sides are the same for this board.
6. If the address is the same, change the port on the ATM switch
side. This could require administration on the ATM switch.
7. If the error is resolved, the problem is on the ATM switch port.
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 excessive amount of
control messages to the processor. When this error is generated, the system automatically
resets the ATM-EI.
Duplicated PNC? Then:
Yes service to the PN is disrupted
No the system switches to the standby PNC
