AN-miniSDH-V is based on SDH/MSTP technology. It is aimed at providing traditional TDM service and data access, assembling, switching and management functions.AN-MINISDH-C can be applied in metro access network and various special networks with the fusion of voice and data service as a trend.


AN-MINISDH-C is a compact SDH TM (Terminal Multiplexer) 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. It provides 16 fixed E1 port and one universal slot. For the slot you can choose various card such as E1 card,V.35 card and Ethernet card according to different requests.
