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，数字传输设备是建立在pdh （ plesiochronousdigitalhierarchy ）技术标准上，为了连接交换机到pdh传输设备上，在交换机侧需要大量的符合基群速率的终端设备，即符合itu - t标准的2048kbits ( 2m )交换终端电路（如s1240的dtm中继模块， axe10的etc模块）和符合ansi标准的1544kbits交换终端电路等。
