[EFM-OAM] RE: Unidirectional OAM & Clause 46
I'm not sure if I am completely comfortable with that, but it's better than
what is currently in there, which is nothing. Please note that this will
also require a new PICS item to be added, or at least a modification of item
LF4. There are several PICS items that need to be added under the optional
OAM item.
Also, if that sentence is added at the end of bullet b, then it's not
entirely clear what happens when no MAC frames are present. Does the RS
precede each remote fault with a column of idle, or just the first one?
The other issue, which I don't think I got a clear answer on, was the size
of frames that can be sent while in the unidirectional mode. Remembering,
that if these frames get too large (128*4 and less than that for a XAUI
link) then the RS will not properly see the fault condition. That is
something that cannot be changed without a change to the counters in clause
46.
