5. Check capacity and peak bandwidth consumption for the ATM span.
h. Error Type 771: the ATM switch is sending cells with unknown Virtual
Path-Identifier (VPI) and Virtual Channel-Identifier (VCI) addresses.

Repair procedure
The board is not locked to the TDM backplane clock signal. This is
probably due to a Tone Clock problem.
Check for TDM-BUS or TONE-BD errors in the Error Log.
If no other problems are present, reset the circuit pack (reset board
UUCSS)
The fiber is not connected properly to the ATM-TRK board or ATM
switch (or to the multiplexer section [MUX] if present).It is possible
that the board transceivers are not functioning properly.
Run test board UUCSS command.
If Test #1259 fails with Error Code 16, 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.
The fiber signal cannot obtain or maintain STM-1/OC-3 framing.
Try to more the fiber on the ATM switch side to a different port.
If the problem persists, reset the circuit pack (reset board UUCSS).
Then
Reduce traffic on the Avaya
Server CSI to ensure that it is using no
more that its subscribed bandwidth.
