この発明は電話網を利用するファクシミリ通信において
ファクシミリ通信呼を電話通后呼と区別して呼出す方式
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for distinguishing facsimile communication calls from telephone calls in facsimile communication using a telephone network.
近年電話網を利用するファクシミリ通信が普及している
が、交ｆ逸機は電話通信呼とファクシミリ通信呼とを区
別せずに、ファクシミリ通信呼であっても、一般の電話
通信呼と同じ呼出信号を送出している。In recent years, facsimile communications that use telephone networks have become widespread, but most exchange machines do not distinguish between telephone and facsimile calls, and even facsimile calls use the same ringing signal as regular telephone calls. is being sent.
このためにファクシミリ通信呼であっても、電話機のベ

リ通信に移るようにしている。また自動受信装置を付加
した場合では、数回程度電話のベルが鳴動してから、フ
ァクシミリ通信に移るようになっている。For this reason, even in the case of a facsimile communication call, the bell of the telephone rings and the facsimile communication begins after a conversation between the sender and the receiver. Furthermore, when an automatic reception device is added, the telephone bell rings several times before proceeding to facsimile communication.

特徴を生かせず、また電話通信呼をファクシミリ装置に
接続してしまうなどの問題があった。For this reason, even in the case of facsimile communication, if the recipient is called by a ringing bell, and conversely, in the case of telephone communication, if the recipient does not respond within several rings, the system will forcibly switch to the facsimile receiving device. There were some inconveniences such as being exposed. In this way, telephone communication calls and facsimile communication calls are made without distinguishing between them, and as a result, the characteristics of facsimile communication, which is a recorded communication and does not require a response from the operator, cannot be utilized, and telephone communication calls are called as facsimile calls. There were problems such as connection to the device.

がある。One way to distinguish between telephone and facsimile is to install a device that inverts the DC polarity for each subscriber line, and to set the polarity according to each communication, but in this case, the capacitor in the telephone circuit is used to charge and discharge This may cause a problem called "ringing," in which the bell rings momentarily.

で、以下図面について詳細に説明する。まず発信側電話
機１から発呼し、交換局２でその発呼が検出されると、
制御部３の制御により電話機１は通話路スイッチ部４を
介してダイヤル受信部５と接続され、この受信部５から
ダイヤル音が送出される。In order to eliminate these drawbacks, the present invention distinguishes between a telephone communication call and a facsimile communication call at an exchange, and when it is identified as a facsimile communication call, it sends out a facsimile signal that does not ring the telephone bell. The drawings will be described in detail below. First, a call is made from the calling telephone 1, and when the call is detected by the exchange 2,
Under the control of the control section 3, the telephone 1 is connected to the dial receiving section 5 via the communication path switch section 4, and a dial tone is sent from the receiving section 5.
発信者がダイヤル音を聞いてファクシミリ通債呼である
ことを示す特別の番号、例えば１沙と通信相手であるフ
ァクシミリ受信端末の番号（電話番号そのもの）をダイ
ヤルする。The caller hears the dial tone and dials a special number indicating that it is a facsimile bond call, such as 1-sa, and the number (telephone number itself) of the facsimile receiving terminal with which the caller is communicating.
交換局２のダイヤル受信部５では受信したその番号を、

When the control unit 3 analyzes the number 1 fence and identifies that it is a facsimile communication call, it selects the facsimile ringing signal sending trunk 6 and sends the facsimile to the facsimile receiving terminal via the communication path switch unit 4. A calling signal is sent to 7.

認するようにすることもできる。By using an audible signal sound as loud as the IK side or higher as this calling signal, the facsimile receiving terminal 7
The bell of the telephone 8 on the receiving side that is paired with the telephone 8 is prevented from ringing. When the facsimile receiving terminal 7 detects the sent calling signal and automatically answers, the facsimile calling bond sending trunk 6 detects the response signal and connects it to the telephone 1 via the call path switch section 4. The facsimile transmitter terminal 9 and the facsimile receiver terminal 7 are connected,
Facsimile communication begins. On the other hand, the calling phone 1
In the case of a telephone communication call that calls the called telephone 8 from
If the special number 1 is not sent and the controller 3 analyzes it and finds that it is a telephone communication call, it selects the trunk 10 for transmitting a false call signal and calls the called telephone 8. A signal is sent out. This call signal generally includes 18
Since a low frequency signal of about 100 MHz is used, the bell of the telephone 8 rings, and the facsimile receiving terminal 7 does not respond. When the receiver answers by taking the called telephone 8 off-hook, the receiver is connected to the calling telephone 1 and telephone communication is started. Although exchange 2 identified it as a facsimile communication call only by the lxy number, in order to increase reliability, facsimile communication has a subscriber data file device that records whether or not the subscriber has a facsimile terminal. In the case of a call, the exchange 2 can also confirm whether the called party has a facsimile terminal.
また、上述では交換局２が端末相互を接続する回線交換
形の通信形態について述べたが、蓄積センタを介するよ
うな蓄積交換形の通信形態にも適用できる。Further, although the above description has been made regarding a circuit switching type communication form in which the switching center 2 connects terminals to each other, the present invention can also be applied to a store and forward type communication form via a storage center.
以上述べたように、この発明のファクシミリ呼出方式に

別して呼出信号を送出することにより、着信側扱者の応
答を必要とせずにファクシミリ通信が可能であり、また

防止できる。As described above, according to the facsimile calling system of the present invention, the switching center distinguishes between telephone communication calls and facsimile communication calls and sends out a ringing signal, thereby allowing facsimile calls to be made without requiring a response from the called party. This also prevents telephone communication calls from being connected to facsimile machines.

きる。Furthermore, since the facsimile calling signal is an audible signal of approximately IKHz or higher and does not depend on switching of DC polarity, so-called tingling does not occur. Further, this calling signal is sent using a trunk for sending out a facsimile calling signal, so that the trunk for sending out a facsimile calling signal can be effectively used without providing one for each subscriber, and the structure can be constructed at a lower cost.
