A data link control means (17) sets and detects flags, inserts and deletes zeros, processes errors, and controls the priority of a D-channel. A system control means (18) performs overall controls for the telephone, and a plurality of interfacing means (13), (14), (16), (21), (22) are connected to proper positions. The system can be applied to the existing telephones at a relatively cheap cost.
