ABSTRACT:
A multi-directional multiple access communication system includes a master station and subscriber stations including a specific subscriber station. The system performs communications using a demand assignment scheme in which time slots are assigned between the subscriber and master stations only when a call is generated by a subscriber station. The master station includes a first transmission/reception section, a rate conversion circuit, a second transmission/reception section, a memory, and a distribution circuit. The first transmission/reception section performs multi-directional multiple access communication of a time slot signal with each subscriber station excluding the specific subscriber station via a first transmission path. The rate conversion circuit converts a time slot signal into a signal having a transmission rate lower than that of the first transmission path. The second transmission/reception section transmits the converted signal to the specific subscriber station via a second transmission path. The memory stores the first maximum number of time slots which can be transmitted via the second transmission path. The distribution circuit distributes a signal corresponding to the second transmission path within the first maximum number of time slots which is set in the memory.
