that are transmitting multicast frames (point-to-multipoint Emulated LAN traffic) on an ATM
network. Thus, with the LECID_EN bit set to a logic high on a channel, the RSM Coprocessor
looks for a match in the LECID table with the LECID in each received LANE frame, and if a
match, the frame is discarded. This implements echo suppression of superfluous
multi-broadcast LANE traffic on the ATM network.
