Next, when the installation is completed, first, each telephone 2
Any one of b, 3b, 11a, 12a, and 15, for example, the dedicated telephone 2b is off-hook (outgoing line). As a result, the local line call current flows through the photocoupler 21 or 22, and the line monitoring unit 20 determines the polarity of the outside line G1 depending on which of the photocouplers 21 and 22 the call current flows through. Then, in accordance with the result of this determination, as described above, the relay switches 23a, 2a of the polarity switching circuit 23.
3b is switched to break B or make M, and this switching state is maintained as it is. In this way, the polarity of the call current of the outside line G1 and the polarity of the call current of the extension line of the telephone exchange A are automatically matched. Outer line G2 of other system
Is also the same.

Although the above is a normal outside line transmission, for example,
The single telephone 15 connected to the speaker modular 14 has an automatic transfer function and automatically transfers a message when a polar reaction is detected after receiving an outside line. In this case, as described above, since the polarities of the call currents of the outside lines G1 and G2 and the call current of the telephone exchange A definitely match with each other due to the automatic operation, there is a problem in detecting the extreme reversal. There is no such thing.
