What is cdx6500xdlcmx25RNRFramesIn?

Counts RNR (Receive Not Ready) frames received from the line for this MX.25 station, since the counters were last reset; an RNR frame is the peer telling the sender it cannot accept more frames right now. As an admin, a steadily climbing count points to congestion or a slow device on the link.
