号をダイヤルすると、リンギング送出回路3から内線電
話機2ヘリンギングを送出させる。When a call arrives from the office line 5 to the office line trunk 4, the central controller 7 transfers the office line trunk to the register 8 through the switch 1.
Connect to the line side. When the caller dials the extension number of the extension telephone 2, a ringing signal is sent from the ringing sending circuit 3 to the extension telephone 2.
ことで、内線電話機2が一部時間、たとえば、15秒間
応答しないと、中央制御装置7は内fJ!電話機2への
リンギングを停止させ、再度レジスタ8を接続する。Therefore, if the extension telephone 2 does not respond for a certain period of time, for example, 15 seconds, the central control unit 7 will issue an internal fJ! Stop the ringing to the telephone 2 and connect the register 8 again.

者の局加入者番号を記憶させる。When the caller requests automatic callback, dials the special number for automatic callback and the caller's own subscriber number (11), and goes on-hook, the called party is stored in the central controller's 7-digit automatic callback storage device 9. The extension number of the extension telephone 2, which is an extension, and the calling party's subscriber number are stored.

号を読み出し、センダ6より局線5に送出する。As a result, the central control unit 7 calls the called extension from the automatic callback storage device 9 at regular intervals.If the extension does not respond for a certain period of time, it calls again after a certain period of time. If the caller responds within a certain period of time, the central office line trunk 4 and sender 6 are captured, the calling party's subscriber number is read from the automatic callback storage device 9, and sent from the sender 6 to the central office line 5.
送出が終了中ると、内線電話機2と局線トランク4とが
スイッチ1によって接続され、発呼者が自動的に呼び返
えされる。When the call is complete, the extension telephone 2 and the central office trunk 4 are connected by the switch 1, and the caller is automatically called back.
