trunk module meaning in Chinese
中继模块
Examples
- The legacy telephone switches all use the 2 mbs ports as their trunk modules
传统的话音交换机使用的中继模块都是2mbits端口。 - From a comparison between the 2 mbits ( etc5 ) and the 155 mbits ( etc155 ) trunk modules , we can see that for the same cabinet , the equivalent number of e1s of the etc155 is four times that of the etc5 while power consumption of the former is merely twice that of the latter
以axe10交换机为例对2mbits中继模块（ etc5 ）和155mbits中继模块（ etc155 ）作一对比可以看出，同样的机柜， etc155的等效e1数量是etc5的４倍，而耗电量只有２倍。 - Besides the protection of the modules themselves , dispersion is another factor we should take into account in organizing a network . for instance , the trunk lines of a trunk should be dispersed to different 155 mbits trunk modules and each 155 mbits trunk modules to different physical routes
除了模块本身的保护机制外，在网络的组织上要考虑分散度，如一个局向的中继线要分散在不同的155mbits中继模块，每个155mbs中继模块要分配到不同的物理路由。 - With the expansion of exchange capacity and network convergence , quite a lot of manufacturers has installed built - in sdh interfaces in their switches so as to provide trunk modules of the stm - 1 ( 155 mbs ) rate , such as shanghai bell s p3s exchange and huawei s c & co8 exchange
随着交换机容量的扩大和网络融合的趋势，目前已经有相当多的厂家都内置了sdh的接口，能够提供stm - 1 ( 155mbits )速率的中继模块，具体如上海贝尔的p3s交换机和华为公司的c & c08交换机。 - 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。
