側から回線の断続を行う必要性が増大してきている。The Telecommunications Business Law, which came into effect in recent years, has made it possible for users to install terminal devices such as telephones and facsimiles. On the other hand, such installation by the user may cause a failure of the communication line. Therefore, in order to clarify the cause of the failure of the communication line from the terminal device side or the station side without going to the user's house, it is increasingly necessary to connect / disconnect the line from the station side by remote control.

The thyristor 60 is turned on, the solenoid 58 of the relay 56 is excited, and the normally closed contacts 64 and 66 are opened. As a result, the terminal device side 62 is separated from the office side 72 from the remote carving device 48.

If there is a break in the communication lines 50, 52 on the side of the terminal device 62, no current will flow even if a voltage of less than 110 V is applied between the station terminals L1 and L2, but if a voltage of 110 V or more is applied, a current will flow. Furthermore, the communication lines 50, 52 on the station side 72 from the remote isolation device 48
Alternatively, if there is a short circuit in the communication lines 50, 52 on the terminal device side 62, a current flows in a manner substantially proportional to the voltage, and the current value is larger than in the normal state.
