Composite terminal equipment for isdn

Abstract

Abstract PURPOSE:To make the synchronization coincident at the start of B1 and B2 channels in the case of using the channels at the same time by synchronizing data strings of the channels B1 and B2. CONSTITUTION:A B-channel data transmission section 33 sending a B-channel synchronizing data, a B-channel data reception section 34 receiving a B-channel data sent from an opposite composite terminal equipment, a B-channel data synchronizing section 35 correcting a data string taking synchronization of a data string of the channels B1, B2 and a D channel interface section sending the information taking the synchronization of the data strings of the channels B1, B2 are provided to the terminal equipment to take the synchronization of the data strings of the channels B1, B2. Thus, the phase of channels L, R is synchronized and audio and video signals are synchronized, the channels B1, B2 are regarded as one 128kbps channel and the high speed data is transferred.
