4 will be described with reference to the sequence diagram of FIG. In FIG.
During a call between the telephone of the master station and the telephone of the slave station, a setting PB signal is transmitted from the telephone of the master station. In the line control device of the master station, the PB signal is detected by the PB signal detector, and a setting signal is transmitted to the slave station. The slave station outputs a setting guidance sound to the telephone upon receiving the setting signal, and switches to the secret circuit. The master station transmits the setting signal and switches to the secret circuit after a certain period of time. Thus, the setting of the confidential call between the master station and the slave station is completed. When releasing the confidential call from the telephone of the master station, the line controller of the master station sends a release PB signal from the telephone of the master station. The line controller of the master station receives the release PB signal and sends a release signal to the slave station. In the slave station,
Upon receipt of the release signal, a release guidance sound is output to the telephone set to switch to the normal circuit. The master station switches to the normal circuit after a certain period of time after transmitting the release signal. As described above, the release of the confidential call is completed.

なる。In FIG. 3, while the telephone of the master station and the telephone of the slave station are communicating, a set PB signal is transmitted from the telephone of the slave station. In the line control device of the master station, the PB signal detector detects this PB signal.
The B signal is detected and a setting signal is sent to the slave station. Upon receiving the setting signal, the slave station outputs a setting guidance sound to the telephone and switches to the secret circuit. The master station sends a setting signal and switches to the secret circuit after a certain period of time. Thus, the setting of the confidential call between the master station and the slave station is completed. When releasing the confidential call from the telephone of the slave station, a release PB signal is transmitted from the telephone of the slave station. The line control device of the master station receives the cancellation PB signal and sends a cancellation signal to the slave station. Upon receiving the release signal, the slave station outputs a release guidance sound to the telephone and switches to the normal circuit. The master station sends a release signal and switches to the normal circuit after a certain period of time. As described above, the release of the confidential call is completed.

匿通話の解除が完了となる。In FIG. 4, while a telephone set of a slave station is looping back at an exchange, and a telephone call is in progress, a set PB signal is transmitted from one of the telephone sets. In the line control device of the master station, the setting PB signal is detected by the PB signal detector, and a setting signal is sent to each slave station. Upon receiving the setting signal, the slave station outputs a setting guidance sound to the telephone and switches to the secret circuit. In this case, since the set guidance sound overlaps as indicated by the x part in the figure, the master station line controller cuts off the voice from the exchange for a certain period of time and then switches to the secret circuit. Thus, the setting of the confidential call between the slave stations is completed. When releasing the confidential call from one of the telephones, a release PB signal is transmitted from the releasing telephone. The line control device of the master station receives the cancellation PB signal and sends a cancellation signal to each slave station. Upon receiving the release signal, the slave station outputs a release guidance sound to the telephone and switches to the normal circuit. In this case, since the release guidance sound overlaps as indicated by the X portion in the figure, the line control device of the master station switches off the sound from the exchange for a certain period of time and then switches to the normal circuit. As described above, the release of the confidential call is completed.
