ABSTRACT:
In a digital, time division multiplex communication system, a first-in, first-out buffer (10) at each subscriber station is employed to establish a conference call. The digital words of the conferees being listened to are entered into the buffer as they are received. They are then read out at a different bit rate such that they all occupy an equal fraction of the word period. The words are decoded in a standard D/A converter (11) and combined in a filter (12).
