VC End-to-End Point
When a VC connection point is set as an endpoint (end-to-end), it operates as
follows:
• F4 and F5 segment and end-to-end OAM cells are dropped from the cell
stream. F5 end-to-end AIS, RDI and CC cells are monitored.
Figure C-25. VC Endpoint – Case A
• When F5 end-to-end AIS cells are received, AIS state is declared and F5
end-to-end RDI cells are generated towards the backward direction.
Figure C-26. VC Endpoint – Case B
•
When a failure is detected on the physical port, AIS state is declared and F5
end-to-end RDI cells are generated towards the backward direction.
Figure C-27. VC Endpoint – Case C
• When a VC endpoint is set as a CC source point, F5 end-to-end CC cells are
generated towards the backward direction every second.
