例句与用法：

For the backbone nodes , high - capacity dacs4 - 4 - 1 cross connect equipment with stm - 1s as its basic interfaces is used . between the various equipment.

stm - 1 connections are directly used instead of tens of 2 mbits connections so that large amounts of hw equipment , power consumption , connecting lines between shelves and fault rate can be reduced , while network redundancy can be improved.

骨干节点采用以stm 1为基本接口的大容量dacs4 - 4 - 1交叉机。各种设备之间直接使用stm - 1连接，不再使用几十个2mbits连接，可以大大减少设备硬件数量，降低电源消耗，机架之间连接线显著减少，降低故障发生率，提高网络冗余度，也可以降低建设和维护成本。
