【発明の詳細な説明】
本発明はボタン電話機、特にボタン電話機の扱−ドの点
滅によって確認することができるようにしたボタン電話
機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button telephone, and more particularly to a button telephone that can be identified by blinking the operating code of the button telephone.
X回線に送出されていることを確認できず、扱者が不安
感を抱くことがあった。There were times when operators felt uneasy because they could not confirm that the information was being sent to the X line.

5 is a network.
ボタン電話機の扱者がダイヤルパット100を押すこと
により、マトリクス状のダイヤル接点がメークしダイヤ
ル接点のメーク信号が符合化回路101に送出される。When the operator of the button telephone presses the dial pad 100, a matrix of dial contacts is made and a make signal of the dial contacts is sent to the encoding circuit 101.
符合化回路101は上記メーク信号を検出し1.2.3
〜0を4ビツト構成の2進化符号に符号化する。この符
号化された信号は随時20桁のメモリ回路102に入力

1発光ダイオード104に供給する。The encoding circuit 101 detects the above make signal and performs 1.2.3
~0 is encoded into a 4-bit binary code. This encoded signal is input to the 20-digit memory circuit 102 at any time and stored therein. The memorized dial data is sent to the memory circuit 102 at fixed time intervals, for example, 10/20 PPS.
is output as a dial pulse signal. This output dial pulse signal 7 is sent to a central office line or PBX line via a network 105, and at the same time is passed through a resistor 103 that limits the current to a constant current of, for example, 10 mA.
1 light emitting diode 104.
このようにすることにより局線またはPBX回線に送出
されるダイヤルパルス信号と同期してダイヤルパルス送
出の有無を発光ダイオード104により表示することが
できる。By doing so, the light emitting diode 104 can display whether or not a dial pulse is being sent in synchronization with the dial pulse signal sent to the office line or PBX line.
本発明は以上説明したようにダイヤル発信によって送出
されるダイヤルパルス信号を発光ダイオードによって検
