...Figure 2 shows the principle of digital switching using an example of a relay exchange. This model shows a simple exchange with two incoming and two outgoing multiplexed lines for three-channel multiplexing. It is an example of a case where it is composed of a time switch (also called a T switch) that has the function of changing the time order of each channel on the highway (multiplexed lines in the switch circuit), and a space switch (S switch) that arranges electronic gates spatially and switches and connects each channel between highways. Digitally multiplexed calls (individual communication signals) come in to the incoming multiplexed lines. ... *Some of the terminology that mentions the "S switch" is listed below.

…図2はディジタルスイッチングの原理を中継交換の例について示したものである。このモデルは3チャンネル多重の2本の入多重回線と2本の出多重回線をもつ簡単な交換機を示しており,ハイウェー(スイッチ回路内の多重回線)上の各チャンネルの時間順序を入れかえる機能をもった時間スイッチ(Tスイッチともいう)と,空間的に電子ゲートを並べてハイウェー相互間でチャンネルごとに切換接続を行う空間スイッチ(Sスイッチ)とから構成されている場合の一例である。入多重回線にはディジタル多重化された呼(個々の通信信号)が入ってくる。… ※「S スイッチ」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
