SYSTEM FOR CONSTITUTING FRAME OF TIME DIVISION MULTI-ACCESS RADIO EQUIPMENT

摘要

PURPOSE:To easily exchange a radio section for exchange highway, by transmit ting individual signals of each group by sharing the signals by means of even and odd time slots which are prepared by assembling and converting the individ ual signals. CONSTITUTION:The frame constitution of a radio telephony terminal is made to match the frame constitution of the PCM primary group of a digital private branch exchange highway. Since the frame length of the highway is 128mus, the frame length of the radio telephony terminal system is set at 125XNmus and one time slot is constituted of 8Xnbits. Then the terminal system is coupled with the highway. Time slot Nos. 16 or 0 are rearranged to odd or even time slots and the time slots arranged to odd or even time slots are respectively used for transmitting individual signals of odd or even sound signal time slot groups.
