同報通信情報のもれを防止する手段を備えておく。A means is provided for supplying broadcast communication information to subscribers who are not busy among subscribers provided with a broadcast communication function. The subscriber with the broadcast communication function is provided with means for preventing the broadcast communication information from leaking to the switching subscriber circuit in order to supply the broadcast communication information to the subscribers who are not busy.
以下本発明を図面について詳細に説明する。第“讐図は
本発明の一実施例として継電器を用いた回路にて構成し
た場合の回路図でBXは交換機、TBLOへTBLnは
加入者電話機、0〜nは交換機EXにおける加入者端子
である。The invention will now be explained in detail with reference to the drawings. Figure 1 is a circuit diagram of a circuit using a relay as an embodiment of the present invention, where BX is an exchange, TBLO to TBLn are subscriber telephones, and 0 to n are subscriber terminals in the exchange EX. .
第1図で、電話横置Oが同報通信情報の供給源と想定し
て説明を進める。本図の状態では、単なる交換機収容の
電話機として機能している。In FIG. 1, the explanation will proceed assuming that the horizontal telephone O is the source of broadcast communication information. In the state shown in this figure, the telephone functions simply as a telephone equipped with an exchange.
ここで電話横置Oがオアフックし、加入者端子Sに着信
すべく、公知の方法でダイヤルすると公知の交換機着信
動作が行なわれ、かつ、交換接続中である意味も含めC
O@@器が電話横置Oがオンフックするまで動作を継続
する。Here, the horizontal telephone O makes an or-hook, and when dialing in a known manner to receive a call to the subscriber terminal S, a known exchange terminating operation is carried out, and C is included, which also means that the exchange is connected.
The O@@ device continues operating until the telephone horizontally placed O goes on-hook.
加入者端子Sへの着信はSO継電器を動作させることで
、80人継電器コイルを経由しての直流ループが交換機
に対して形成されることから公知の交換機応答動作が行
なわれ、交換機加入者端子0と加入者端子Sが接続され
る。When a call arrives at the subscriber terminal S, the SO relay is operated, and a DC loop is formed to the exchange via the 80-person relay coil, so a known exchange response operation is performed, and the call is sent to the subscriber terminal of the exchange. 0 and subscriber terminal S are connected.
ここで、前記直流ループにより、80人継電器か動作し
、同報通信機能を付与された加入者計装置 nへ、同報
通信要求が発生した旨の情報が80a”接点を介して、
それぞれ伝達される。Here, the 80-person relay is activated by the DC loop, and information indicating that a broadcast communication request has occurred is sent to the subscriber meter device n, which is equipped with a broadcast communication function, via the contact 80a''.
Each is transmitted.

点C1a。At this time, the voice information is supplied to the exchange in the subscriber TILN that is not busy, and the blocking function by the L-coil is activated by the CIA-CN relay so that the AC impedance is high to avoid loss. Contact C1a is opened by the operation of .
C1a”−Cna@、 Cna”が開き働く。C1a''-Cna@, Cna'' opens and works.
今ここで1図中、電話機T E L nは、同報通信中

ル待ち状態となるとともに、 CN継電器を動作させる
。In FIG. 1, it is assumed that the telephone TELn is in broadcast communication but has gone off-hook. Since the DC loop of the telephone horizontally placed N can activate the exchange through the coil LN, the exchange detects the OFF 7-tap state and enters the known dial waiting state, and activates the CN relay.
CN継電器の動作は08人継電器を復旧させるから、回
報通信系から切離され、公知の交換機収容電話機と同等
のものとなる。Since the operation of the CN relay restores the 08 person relay, it is separated from the broadcast communication system and becomes equivalent to a known exchange-accommodating telephone.

る。In the explanation of the embodiment in FIG. 1, we did not mention the subscriber's telephone equipped with the broadcast communication function, but in the on-hook state, the receiving circuit, except for the bell circuit, normally functions both in terms of direct current and alternating current. The one that is disconnected is a regular telephone.

に合致したものに変更するかの処置が必要である。Accordingly, the subscriber's telephone equipped with the repeat communication function used in the present invention either connects the disconnected receiving circuit again, or transmits electromagnetic waves due to alternating current load fluctuations to the bell circuit to an external speaker circuit. If there is a means to detect and amplify the signal, it is necessary to change the bell circuit itself to one that meets the conditions at the time of adding the broadcast communication function.
