に選択番号識別部２４が接続される構成である。FIG. 3 is a block diagram of a switching network selection circuit, in which terminal equipment 1 such as a telephone, PBX, or button telephone is connected to a selection signal receiving/sending section 21 and an incoming call detection section 22, and a subscriber line from the switching network is is connected to the switching network selection section 23, and a selection number identification section 24 is further connected between the selection signal receiving/sending section 21 and the switching network selection section 23.
以下、動作について説明する。The operation will be explained below.
端末機器１からの発信信号を選択番号受信／送出部２１
が受信すると、発信音を該端末機器１へ送出する。Select number receiving/sending section 21 receives the outgoing signal from the terminal device 1
When received, it sends a dial tone to the terminal device 1.

。The switching network selecting section 23 selects a switching network according to the control signal, and connects the subscriber line of the selected switching network to the selection signal receiving/sending section 21. Further, the selected number receiving/sending section 21 receives a calling instruction from the selected number identifying section 24, performs a calling operation to the connected subscriber line (normally, the subscriber line is looped), and sends the call from the switching network to the connected subscriber line. After receiving and identifying the dial tone,
Sends out the stored selection numbers and additional numbers necessary for network selection. Through the above operations, the selected number from the terminal device 1 is sent to a predetermined switching network based on that number.
次に選択した交換網が障害、ふくそう等で着信端末装置
へ接続不可の場合を説明する。Next, a case will be explained in which the selected switching network is unable to connect to the receiving terminal device due to a failure, congestion, etc.
交換網の障害、ふくそう等は種々の状態が考えられるが
、ここでは発信時、交換網からダイヤルトーン（ＤＴ）
が受信できない状態（交換網の交換機のシ支テムダウン
）にあるものとする。There are various possible causes of switching network failures, congestion, etc., but here, when making a call, a dial tone (DT) is sent from the switching network.
It is assumed that the system cannot receive data (the system of the exchange in the exchange network is down).

再選択指示を行なう。In the above explanation, the selected number receiving/sending unit 21 receives and identifies a dial tone (DT) from the switching network after making a call, and sends out a selected number.
T) is measured, and if it exceeds a certain time, it is determined that there is an abnormality in the switching network. If it is determined that there is an abnormality, the transmission operation is stopped and a re-selection instruction is given to the selection signal identification section 24.
選択信号識別部２４では再度、網選択テーブルを参照し
、次の交換網の選択を行なう。その後の動作は前述した
動作と同様である。なお、網選択テーブルには予め第１
