ある。The method for confirming whether a call can be made according to the present invention becomes a calling state when the next calling signal does not come after receiving a calling signal;
A terminal device is provided that maintains a calling state with a terminal, calls the terminal from another terminal, and after recognizing the calling signal, disconnects the terminal,
After a certain period of time, the terminal is called again, and by receiving a busy signal, it is confirmed that the terminal is capable of making a call.

る。In this invention, the telephone terminal to be confirmed is called from any telephone terminal and the telephone terminal is then hung up, whereby the terminal device provided on the side to be confirmed becomes in a calling state. here,
When the telephone terminal on the side to be confirmed is called again, since it is in a calling state, a busy signal is emitted, and upon receiving this, the calling state is confirmed.
以下、この発明の実施例を図面とともに説明する。第１

のハンドセットを上げるとオンフック状態となり、相手
側からの呼出しがあると話中音を発信するようになる。Next, the operation of the above configuration will be explained. 1. First, when the telephone 2 is not in use, the subscriber monitoring circuit (relay) 8 is not operating. In other words, when the handset on the telephone 2 side is put down (off-hook), the electrical connection (<KN, circuit) is disconnected (open) as seen from the exchange 6, and when the handset is lifted up, it becomes on-hook and the other party When there is a call from the side, a busy tone will be emitted.
ここで、任意の電話機１をダイヤルして電話機２をオフ
フック状態のときに呼出すと、呼出信号（１秒送出、２
秒休み）が、交換機６から加入＠線路４を介して電話機
２および端末装４ｔ１０に送られ、電話機２のベルが鳴
動する。一方、端末装置１０においては、呼出信号受信
回路１１で呼出信号を受信し、受信出力を発呼状態開始
遅延回路１２に与える。遅延回路１２は最初の呼出信号
でセットされ、次の呼出信号でリセットされるが、次の
呼出信号が当然くるべき時間を経過しても無い場合、具
体的には最初の呼出信号を受けてから５〜１０秒経過し
ても次の呼出信号がない場合には発呼回路１４に指令を
与え、発呼回路１４を動作させる。Here, if you dial any telephone 1 and call telephone 2 when it is off-hook, the ring signal (sent for 1 second, 2
seconds off) is sent from the exchange 6 to the telephone 2 and the terminal 4t10 via the subscriber line 4, and the bell of the telephone 2 rings. On the other hand, in the terminal device 10 , the calling signal receiving circuit 11 receives the calling signal and provides the received output to the calling state start delay circuit 12 . The delay circuit 12 is set by the first ringing signal and reset by the next ringing signal, but if the next ringing signal does not arrive even after the expected time has elapsed, specifically, the delay circuit 12 is set by the first ringing signal and reset by the next ringing signal. If there is no next calling signal even after 5 to 10 seconds have elapsed, a command is given to the calling circuit 14 to operate the calling circuit 14.
これにより、前記したように直流回路が継がり、交換機

動作を検知して１０〜２０秒間発呼状態を維持するよう
に発呼回路１４に指令を与える。As a result, the DC circuit is connected as described above, and the exchange 6 emits a tone indicating that the receiver is ready to accept. Further, the calling state maintenance circuit 13 detects the operation of the calling circuit 14 and gives a command to the calling circuit 14 to maintain the calling state for 10 to 20 seconds.

受信回数を定め、それ以後は受は付けないようにしても
良い。The method for confirming whether a call can be made in this embodiment utilizes the above-mentioned terminal device.First, telephone 1 calls telephone 2, and after recognizing the calling signal, the call is hung up. This results in
The terminal device 10 enters the calling state, and after a certain period of time (at least the time during which the exchange 5 can confirm that the terminal device 10 is on-hook, and within the time period during which the call can be made while the call continues), the call is made again from the telephone @1 to the telephone 2.
When called, a busy signal is issued from the exchange 6 because the terminal device 10 maintains the calling state. Therefore, by listening to this signal, it can be confirmed that the terminal device 10, that is, the telephone set 2, is capable of making a call and that it is possible to talk. In the event of a disconnection, the calling signal is sent to the receiving circuit 11.
is not received, and the terminal device 10 does not operate. Therefore, when the telephone 1 makes a call and calls again, the user can hear the ringing tone and confirm that the call cannot be made. Note that in the terminal device 10, since it is wasteful to respond to a call signal for a normal call, the number of times the call signal is received may be determined, and no calls will be accepted after that.

［１０から発呼できないことを確認することができる。Here, on the terminal device 10 side, a ring tone (16H) is sent from the exchange.
2), the incoming call detection circuit 36 detects this, and C
Count with PU29. On the center device 15 side, the other party's ringing tone is received and confirmed by the 16Hz pantone filter 24 via the amplifier 28, the CPU 20 instructs off-hook, and the DI relay 22 and CML relay 23 are restored. - On the terminal device 10 side, the CPU 29 confirms that the ringing tone does not continue and instructs on-hook after 5 to 10 seconds. With this, D, DI relay 31, CML
The relay 32 is activated and the exchange 6 is brought into operation. This calling state continues for 10 to 20 seconds, the CPU 29 instructs off-hook, and the DI relay 31% and the CMLIJ relay 32 are restored. Further, while the terminal device 10 is in the calling state, the CPU 20 issues a re-call instruction on the center device 20 side, the DI relay 22 and the CML relay 23 operate, and the exchange also operates. Next, the CPU 20 issues a selection signal transmission instruction again.
The tone dialer 21 operates, an exchange connection operation is performed, and a call is received on the terminal device 10 side. At this time, since the terminal device 10 is in a calling state, the center device 15
On the other side, the other party's busy tone is received, and the 40
After checking with the 0Hz band pass filter 25, the CPU 20 instructs off-hook, and the DI relay 22 and CML relay 2
3 will be restored. - On the terminal device 10 side, if there is a disconnection in the telephone terminal including the subscriber monitoring circuit 8, the exchange 6 will not operate, so the calling signal will not reach the terminal device 10'', and the terminal device 10 will not operate. Center equipment fiit1
On the 5th side, the other party's ringtone is detected again, and the terminal!
[You can confirm that you cannot make a call from 10.
