传统SDH设备无论是接口速率还是带宽均无法满足直接接入以太网的要求。华为Metro系列多业务传输设备,可以在插入以太网接口板(ET1)的情况下提供以太网透传功能。每块板可将1~8路10/100Mb/s以太网业务采用VC-Trunk方式,映射到SDH群路上的1~48个2Mb/s时隙中,实现对以太网业务的透
Traditional SDH equipment can not meet the requirements of direct access to Ethernet in terms of interface rate or bandwidth. Huawei Metro series multi-service transmission equipment that provides Ethernet transparent transmission with the Ethernet interface board (ET1) plugged in. Each board can use 1 to 8 10 / 100Mb / s Ethernet services in VC-Trunk mode to map to 1 ~ 48 2Mb / s time slots on the SDH group to implement transparent to Ethernet services
