WebFigure 5.14c shows the HDLC operation on one-way data transfer with busy condition. After establishment of link setup the station В transmits the frames (1,1,0; 1,2,0 etc.) from В to A. Since station A is not ready, station A transmits RNR 3 to В showing frame 1,3,0 is not ready to receive. The RNR from A represents busy condition of frame. numbers 24:17 hcsbWeb7-22 Washington University in St. Louis CSE473s '2005 Raj Jain HDLC Family Synchronous Data Link Control (SDLC): IBM High-Level Data Link Control (HDLC): ISO Link Access … nip cs go teamWebApr 5, 2016 · HDLC is superset of SDLC.
