Claims (1)
タ装置間において、 多回数からの呼出しに対し自動着信を行い、順次
その中からデータ送信の要求をもつ回線を走査し
当該の受信回線をセンターのデータ装置に時分割
し接続する、その他の回線からの信号は併結しフ
イルタにかけ除去した後にさらにセンターのデー
タ装置からの出力信号と併わせて全端末のデータ
装置へ同時伝送する、こうした時分割による多回
線間の相互データ伝送を制御する事を特徴とする
多回線間相互データ伝送制御装置。[Claim for Utility Model Registration] Between the data device of the terminal and the data device of the called center, calls are automatically received in response to multiple calls, and lines with requests for data transmission are sequentially scanned. The relevant receiving line is time-divided and connected to the data equipment at the center. Signals from other lines are combined and removed through a filter, and then combined with the output signal from the data equipment at the center and sent simultaneously to the data equipment at all terminals. A multi-line mutual data transmission control device characterized by controlling such time-division mutual data transmission between multiple lines.
