Abstract

PURPOSE:To achieve transmission with good efficiency, by making transmission with a reservation system for audio information long in the occupying time of transmission line comparatively and interrupting the data transmission to a vacant slot where the transmission of the audio information is not made. CONSTITUTION:When an audio information is generated in the timing A, a vacant slot is caught at a slot SO at the next period T. The auido information is transmitted at the caught slot thereafter. Next, when the data is generated at the timing B, a carrier detector 10 detects if the audio information is transmitted to the front part of a slot S2 nearest timewise to check the usage state of the slot. If the slot is vacant, the carrier detector 10 gives the permission of transmission to a transmission circuit 6 and the transmission circuit 6 transmits the data by the vacant slot. If the slot is not vacant, the next slot S3 is the objective transmission.
