PURPOSE:To reduce the amounts of hardwares and softwares necessary for connecting a terminal to a private branch digital exchange by allocating prescribed time slots of the exchange to respective ones of the terminals to be concentrated, and redisposing the terminals to the time slots after the concentration and accommodating them. CONSTITUTION:A 'dial-able'-signal transfer is written in the field #614 in the individual signal time slot of a link down frame. Accordingly, a radio telephone terminal 614 transmits an audible sound. A caller, after hearing this sound, dials the telephone number of the opposite. The dialed number is temporarily stored in the terminal 614. And at the time when the last digit is dialed, the number is collectively transmitted by a link-up individual time slot '4'. The controlling part 77 of an odd-number time-slot-group radio equipment 7, when receiving said dial number via a receiver circuit 76, sequentially transmits it to the field #614 of the time slot of the PCM primary-group frame of exchange highway. |
