Figure C-28. VC Endpoint – Case D
• When a VC endpoint is set as a CC sink point, F5 end-to-end CC cells are
expected to be received every second. If no CC cell has been received during
the last 3.5 seconds, AIS state is declared and F5 end-to-end RDI cells are
generated towards the backward direction.
Figure C-29. VC Endpoint – Case D
• When a VC end point is set as CC both, it functions both as a source and a
sink point.
• For OAM loopback cells (see C.3 OAM Loopback ), an ID match check
determines the loopback state (see
Figure C-30
), and delays are calculated if
the loopback cell has been authenticated and returned within 5 seconds (see
Figure C-31
):
