PURPOSE:To realize the communication of plural routes at one time between optional terminal devices without providing a centralized exchange station, by deciding the own transmission time slot from the address information of the transmitting side which shows the clock pulse synchronized with the bit of the received packet and the time slot number. CONSTITUTION:When the own transmission time slot is designated by the information of an address frame RAF of the receiving side, the information of an address frame TAF of the transmitting side is decoded to be fed to a timer TM in the form of the address information C showing the time slot number of the received packet RK. Then a error is detected in accordance with the information of a data frame DAF and an error detecting frame EDF. At the same time, the information of the frame DAF is converted into a receiving data D and fed to either one of terminal devices TM1-TMn via a connecting circuit CON. Then the timer TM starts the counting of the clock pulses B and obtains relatively the time slot allotted to the timer itself from the time slot number shown by the information C and the count number of the pulses B. And the data of own station is transmitted at the time point of the corresponding time slot. |
