PURPOSE:To provide wake up service to a subscriber without waiting by connecting an ROM storing patterned voice data to provide wake up service and connecting a buffer memory, a reading circuit and a voice composing circuit to a subscriber's circuit. CONSTITUTION:A CPU15 reads out the voice data of plural subscribers having extension telephone sets 12-1-12-n which are requested by reservation from a read-only memory (ROM) 16 and sends the read-out contents to subscriber's circuits 11-1'-11-n'. When it reaches required time reserved by the plural subscribers, the CPU15 applies a command to a reading-out circuit out of circuits 17-1-17-n. Receiving the command, the reading-out circuit reads out voice data stored in a temporary read/write memory successively from the leading address. The voice data read out successively are composed to analog signals by a voice synthesizing circuit out of the circuits 17-1-17-n and the analog signals are sent to respective subscriber's extension telephone sets 12-1-12-n. |
