の目的を完全に蓮成することができる。以下、本発明の
実施例について図面を参照して説明する。A multi-frequency oscillator for inter-office signals is connected to a multi-frequency receiver for inter-office signals, and a multi-frequency oscillator for inter-office signals is connected to each of the three inputs of the three-way trunk via a communication path switch network so that different receivable frequencies can be input to each of the three inputs of the three-way trunk. At the same time, the multi-frequency receiver is connected to the three-way trunk output, and the multi-frequency oscillator generates the three-way signal.
Creates a state in which no signal is applied to the input, a state in which a signal is applied to only one of the three inputs, and a state in which a signal of a different frequency is applied to any two of the three inputs, and receives reception for that state. The system is configured to determine whether or not the three-way call trunk is good or not by checking the frequency with the multi-frequency receiver. According to the above configuration, the object of the present invention can be completely achieved. Embodiments of the present invention will be described below with reference to the drawings.

各々接続され、三者通話トランク６の出力端子１０，１
１，１２のうちの１つが通話路スイッチ網５を経由して
、多周波受信機４の入力となる。The outputs of the multi-frequency oscillators 1, 2, and 3 are connected to the input terminals 7, 8, and 9 of the three-way trunk 6 via the channel switch network 5, respectively, and the output terminals 10, 9 of the three-way trunk 6, respectively. 1
One of the signals 1 and 12 passes through the channel switch network 5 and becomes an input to the multifrequency receiver 4 .

れていないので三者通話トランクの出力端子１０，１１
，１２のいずれかに関しても、多周波信号が検出されな
いのが正常である。When the three-way trunk is in the no-call mode, no signals are applied from the multi-frequency oscillator to the three inputs of the three-way trunk, so the output terminals 10 and 11 of the three-way trunk
, 12, it is normal that no multi-frequency signal is detected.

れるのが正常である。When the three-way call trunk is in the two-party call mode, it is normal that the multi-frequency signal input from the designated input terminal of the three-way call trunk is received only at the designated output terminal. For example, if the 7 input terminals are to be output to the 12 output terminals, the multi-frequency signal input to the 7 input terminals will be received from the 12 output terminals. When the three-way call trunk is in the three-way call mode, all multi-frequency signals input from the two input terminals are output from the output terminal corresponding to the remaining one input terminal and received by the multi-frequency receiver. is normal.
