AN-MINISDH-V is a compact SDH TM with STM-1 interface. It can connect with any standard STM-1 optical port , connect to the backbone network directly and build point to point network. 4 E1s,2 V.35 ports and 100Base-T Ethernet service can be supplied. We provide several concrete types of AN-miniSDH-V, so you can select the best one according to you requests.
AN-MINISDH-V can work as terminal equipment either in the point to point network or in other complicated network topologies inter-working with other MSPP Express products. It is mainly used in access layer network to supply various services such as STM-1,E1,V.35, Ethernet.(Fig 2-1)Typical applications include big client access,3G mobile station connection and etc.. Together with other MSPP Express products, AN-MINISDH-V can provide flexible network building and access capability. In addition, it can independently apply in various special transport networks with mezzo portfolio.
