  7. Before the 1990s, the digital transmission equipment was based on the technical standards of plesiochronous digital hierarchy ( pdh ). in order to connect the switch to pdh transmission equipment, the switch side needs lots of terminal equipment of the primary rate, i. e., 2048 kbits ( 2m ) switching terminal circuits in compliance with itu - t standards ( e. g. s1240 s dtm trunk module and axe10 s etc module ) and ansi - standard - based 1544 kbits ones

    在90年代初期以前，數字傳輸設備是建立在pdh （ plesiochronousdigitalhierarchy ）技術標準上，為了連接交換機到pdh傳輸設備上，在交換機側需要大量的符合基群速率的終端設備，即符合itu - t標準的2048kbits （ 2m ）交換終端電路（如s1240的dtm中繼模塊， axe10的etc模塊）和符合ansi標準的1544kbits交換終端電路等。
