Abstract

PURPOSE:To double the utilizing efficiency of high-way, by using one time slot on the highway as to one set of communication and using the highway for both. CONSTITUTION:A digital audio signal at caller side 1A reaches a rception terminal R of a codec circuit 3B at called party side from the transmission terminal of a codec circuit 8A through a gate GS1 of an inversion gate circuit 8A, highway 9A,and gate GR2 of an inversion gate circuit 8B. A digital audio signal at caller side 1B reaches the reception terminal R of the codec circuit 3A of caller side through a gate GS2 of an inversion gate circuit 8B, highway 9B, and gate GR1 of gate GS2 of an inversion gate circuit 8A from the transmission terminal S of the codec circuit 8B. Thus, the call between subscriber telephone sets 1A, 1B can be made mutually with only one time slot TA.
