FIELD: data coding and decoding; synchronous telecommunication systems. SUBSTANCE: device has data transmission unit and data reception unit connected on opposite ends of communication line; data transmission unit has sync signal generator, coder, group of output amplifiers, register, decoder, inverter, flip-flop, and AND gate; data reception unit has group of input amplifiers, decoder, register, two delay circuits, AND gate, and inverter. Data transmission speed is enhanced due to use of additional communication channel connected in parallel with main one without increasing number of twisted pairs of line conductors. EFFECT: enhanced data transmission speed. 1 cl, 7 dwg |
