********* THIS OBJECT IS DEPRECATED ********* This counter is incremented by one for each frame received on any port that meets all of the following conditions: a) The CollisionEvent signal is not asserted. b) The ActivityDuration is greater than ValidPacketMinTime. c) The frequency (data rate) is detectably mismatched from the local transmit frequency. The exact degree of mismatch is vendor specific and is to be defined by the vendor for conformance testing. When this event occurs, other counters whose increment conditions were satisfied may or may not also be incremented. This counter is the summation of the values of the rptrMonitorPortDatRateMismatches counter for all of the ports in this repeater.
