    1. Detailed information


    HC-DM3721

     

    Overview

    HC-DM3721 is a compact SDH device with STM-1 interface. It can connect with any standard STM-1 optical port, connect to the metro network directly and build point to point network. 8×E1 lines, 2×100Base-T Ethernet service can be supplied.

    HC-DM3721 can work as terminal equipment in the point to point network. It is mainly used in access layer network to supply various services such as STM-1, Ethernet typical applications include big client access,3G mobile station connection and etc.

     

    Feature

    Standard STM-1 optical ports, 1+1 protection supported, dual or single fiber WDM transmission, different wavelengths and powers can be selected.

    Standard SDH mapping of various service interfaces.

    Ethernet mapping adopts GFP/VC-12 virtual concatenated technology, Laps and PPP/HDLC protocol.

    Comply with ITU-T G .703

    E1 port has on-line error surveillance and loop back test function

    NM port for management

    Standard 19 inch 1 U

    Both supply -48V DC and 220V AC

    Can be configured or managed by CLI, DIP switch or HCView NM software
