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.

• Standard STM-1 port，single fiber transmission ,different wavelengths and launched powers supported  ；
• Provide ALS function for optical interface；
• Standard SDH mapping of various service interfaces；
• Ethernet mapping adopts GFP/VC-12 virtual concatenated technology; according with MSTP criterion；
• Comply with ITU-T  G .703;E1 port has on-line error surveillance and loop-back test function；
• NM（10Base-T）,RS-485 software management interface；
• Standard 19 inch 1 unit box；
• -48V DC or 220V AC or +24V DC power supply
• Supply invalidation and loss indication，remote AC220V power loss indication for terminal equipment as a plus；
• Substrate program on-line update supported.
