Application Summary AI generated
This standard specifies the frame structure, procedures, and elements of the High-level Data Link Control (HDLC) protocol for data communication between systems. It is applied in telecommunications and information exchange environments, such as network equipment, modems, and point-to-point or multipoint data links, to ensure reliable and error-controlled transmission of data frames. The standard is used by engineers designing or testing data link layer implementations in IT and telecommunication systems.
