S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
Note, in the unlikely event that a segment VPC-AIS cell is received on the end-to-end VPC
connection, no action would be taken at the F5 level. This is because the VPC connection is only
configured as an end-to-end point and no segment OAM cells should be received. The end-to-
end VPC connection would only terminate the segment VPC-AIS cell and no further action
would be taken at the F4 level.
The table below summarizes the behavior of the S/UNI-ATLAS-3200 for F4 to F5 Fault
Management:

No action is taken. This represents an unusual case where an F4 segment AIS
cell is received on a F4 connection end-point. The segment AIS cell will be
terminated at the VP connection end-point, but no other action is taken.
