ABSTRACT:
When a closing time for data transmission is reserved by a transmission source terminal, a multi-point control unit secures idle time periods of a destination terminal before the closing time, and enters this information in a central storage unit. If a plurality of destination terminals are set, the multi-point control unit enters destination terminal information and transmission closing time information for each individual destination terminal. When a transmission reserved time is reached, the multi-point control unit transmits the data entered in the central storage unit through communication lines.
