PURPOSE:To revise the information quantity addressed to a reception station or a reception station group quickly and to avoid the effect on other station when the quantity of information subject to multiple address communication addressed to the reception station or the reception station group by adding an address to a pre-position of each time slot for a time division multiplex signal sent from a transmission station. CONSTITUTION:A caption 'F' indicates a frame synchronization flag representing a head of each frame comprising plural (n) sets of conventional time slots TS1-TSn. Captions 'A1-An' are reception destination names for each of the plural (n) sets of time slots TS1-TSn and each of the time slots TS1-TSn having a fixed length accommodates multiple address information. When the quantity of information sent to a same destination exceeds one time slot, a transmission station accommodates the quantity of information while being divided into plural time slots and sets the destination to each time slot. When the information is accommodated in the plural time slots, the transmission information is filled sequentially from an idle time slot closer to the synchronization flag F at the head of the frame. Each reception station accepts only the frame whose destination address is coincident with a preset destination address by sequentially comparing each destination address in the received frame with the preset destination address to be received by the reception station. |
