RE: [RPRWG] What rcvdFairRate should be used if SC-FCM are not being received?
Michael,
My answers:
1) Good catch. It is not stated, and therefore needs to be. (I'll expect a comment from you against D2.1 to address this issue.) My recommendation would be to initialize the last rcvdFairRate with the same value the localFairRate is initialized with.
2) From a fairness control unit point of view, it does not time out. (See (3) for why it doesn't need to.) Whatever the last one was, is the one used.
3) Yes. Note that this is already specified in Clause 11.

Subject: [RPRWG] What rcvdFairRate should be used if SC-FCM are not
being received?
In section 9.3.1 of D2.0, it indicates that the most recently received
rcvdFairRate value should be used in the aging interval calculations.
My questions relate to this.
1) What rcvdFairRate should be assumed if a rcvdFairRate has *never* been
received. Should a rcvdFairRate of FFFFh be assumed initially?
2) What rcvdFairRate should be assumed if a rcvdFairRate has not been
received for "a while" (like 10 or N intervals), but has been received at
least once. Should a rcvdFairRate of FFFFh be assumed after this period?
3) Should a Signal Fail indication be sent to the Protection Machine if 2)
occurs?
