This read-only counter, in cells, tracks the combined total of Backward RM and Foresight RM cells in the egress direction of this channel after the traffic management entity. An admin uses this to confirm ABR backward feedback cells are still flowing outbound after policing, which is necessary for the connection's rate-control mechanism to keep functioning correctly. For example, an unexpected drop in this combined RM-cell count after a policy change would alert the admin that egress traffic management might be inadvertently filtering feedback cells needed by the ABR algorithm.
