Three fundamental types of HDLC frames may be distinguished: • Information frames, or I-frames, transport user data from the network layer. They can also include flow and error control information piggybacked on data. • Supervisory frames, or S-frames, are used for flow and error control whenever piggybacking is impossible or inappropriate, such as when a station does not have data to send. S-frames do not have information fields.
