搬送回線に接続される。Conventionally, dedicated telephones are used depending on the purpose. For this reason, it is necessary to prepare a wide variety of telephones, of which only a small number are used. Furthermore, when transporting subscribers, it is necessary to install a telephone repeater between the transport line and the telephone, and even when the number of subscriber lines is small, it is necessary to install a telephone repeater, which is uneconomical. For example, as shown in FIG. 1, a 4N type transmitting line 4WS and a 4-wire type receiving line 4WR that input/output to a modulator/demodulator of a subscriber carrier terminal station (not shown) are combined by a hybrid coil H to form a -C2-wire type. A telephone repeater 5 equipped with a built-in signal device RG that is connected to the signal transmission line SS and signal reception line SR and performs the necessary signal conversion is installed between the general telephone 1 for the dial pulse method and the carrier line. are doing. Further, power for operating the telephone is supplied to the telephone 1 via the signaling device RG. Telephone 1 is connected to telephone circuit network 2. It has a built-in handset 3, dial 4, etc., and the dial signal and the transmitted/received audio signal are connected to the carrier line by the telephone repeater 5 via the telephone circuit network 2.
電話機１を直接搬送回線に接続することはできない。Telephone 1 cannot be directly connected to the carrier line.
本発明の目的は、上述の従来の欠点を解決し、多目的に

As before, it has a telephone network 2 and a handset 3. However, it does not have a dial mechanism, but instead has a dial pulse generation circuit 9, which allows necessary dial pulses to be generated by operating the keyboard 7. Further, if necessary, it is also possible to send out a multifrequency signal (MF multiplied signal) from the multifrequency signal generation circuit 8. These signals are arbitrarily switched and connected by a switch 10.

スイッチ１４によって電話機用レピータ５に接続する。Transmission/reception signals and the above-mentioned dial pulse or MF double signal can be transmitted through the telephone circuit network 2 through the telephone repeater 5 to the carrier line 1 - or to the normal two-wire telephone line 2W. is also possible. The switch 11 is a switch that performs the above switching. When connected to a carrier line, it is necessary to supply direct current power DC for operating the telephone via the switch 11. Note that the AC/DC adapter 12 that rectifies the commercial power can also provide an operating DC power source from the commercial power source. Further, when used as a shared power system, the ringback tone circuit 13 is connected to the telephone repeater 5 by a switch 14.
これらはすべて電話機筐体内に実装されている。本実施
例によれば、加入者搬送に使用する場合に、搬送装置と
電話機の間に別に電話機用レピータを接置する必要がな
いから、小数回線の加入者搬送方式では特に経済的とな
る。All of these are implemented inside the phone case. According to this embodiment, when used for subscriber transport, there is no need to separately install a telephone repeater between the transport device and the telephone set, so it is particularly economical in a subscriber transport system with a small number of lines.
