ABSTRACT:
A multipoint teleconference system dispensing with an MCU, in which terminals are connected into a loop configuration through an ISDN in such a way that each terminal is coupled with each of the adjacent terminals by a single B channel. Thus, a communication frame is revolved through a looped communication channel. Each terminal enters control information for controlling a multipoint teleconference, into a predetermined area within the communication frame, and it relays the resulting communication frame to the next terminal.
