Register Descriptions
Indication for update of RM cells (ABR service category) relating
to the VP or to the individual VC, respectively:
0
Congestion is indicated via VC RM cells (F5 flow).
VC RM cells are identified with PTI=110 and VCI <> 6.
1
Congestion is indicated via VP RM cells (F4 flow).
VP RM cells are identified with VCI=6 (regardless of the
value of the PTI field)
Note: According to the standards, VP RM cells MUST
have VCI=6 and PTI=110. If cells with PTI=110
and VCI <> 6 are contained in the cell stream they
are ignored. This is the correct behavior for an
ABR VC within an ABR VP.
