Abstract
A digital communication apparatus in which time slots need not be switched, comprises a single channel highway in which a plurality of time slots are time-divisionally multiplexed, and first and second transmitting/receiving units connected to the highway. The first transmitting/receiving unit transmits a first signal supplied from a first terminal to the second transmitting/receiving unit through the highway using a first time slot designated from the plurality of time slots. The second transmitting/receiving unit outputs the first signal transmitted from the first transmitting/receiving unit through the highway using the designated first time slot to a second terminal. A second signal from the second terminal is transmitted to the first transmitting/receiving unit through the highway using a designated second time slot. The first transmitting/receiving unit outputs the second signal transmitted from the second transmitting/receiving unit through the highway using the designated second time slot to the first terminal. The first and second time slots are selectively designated from the plurality of time slots in accordance with calling from the first terminal to the second terminal.
