    TOPACCESS
    Description
    TOPACCESS,a new-style optical transmission multi-service access device(hereafter as New-style Access Device for short),is a single-layer SDH product of the latest generation.Taking SDH technology as the core,TOPACCESS provides convergent access,collection,switch,transmission and management functions for TDM service and broadband IP service.It is an optical transmission platform of integrated access that applicable for traditional telecom services and broadband data services.In addition,it is compatible with all PDH services,which makes it applicable for multi-service integrated access for edge networks,various special networks and big telecom customers etc.
    The innovative architecture of TOPACCESS device has expanded SDH technology to edge network.Therefore it is a high-end PDH access device that has taken the advantages of SDH technology into account,which can be applied to meet the current developing demands of big capability and access device integration for various edge devices of access network and special nerwork etc.

    Features
    >>Generally speaking,TOPACCESS new-style multi-service optical transmission platform possesses the following features;
    >>Provides standard STM-1 optical interface,supports ALS(Automatic Laser Shutdowm)function and abides by G.664 standard;
    >>Provides two optical interfaces#1-01 and #1-02,four service access interfaces #2,#3,#4 and #5,and supports hot swap;
    >>Provides 4xE1,10/100Base-T(VC-12 or VC-3 bandwidth)and 2xV.35 interfaces so as to intermix daughter boards of various services and allow different services accesses;
    >>Provide order-wire telephone interface( two-line style) to full point to point calls;
    >>Provides two relay-style overhead alarm output interfaces for prompt alarm and deferred alarm,and two switch input interfaces;
    >>Provides random add/drop of VC-12 channel ,with the service interval to be randomly scheduled;
    >>E1 signal has the functions of retime and pointer justification bypass;
    >>Supports Ethernet interfaces sharing and point-to-point application and be compatible with all PDH services;
    >>With excellent synchronization feature which allows to be synchronized with the line clock or the highly precise internal pulsating source.The line clocks of two optical directions can also be input as the clock reference input.
    >>Diverse topology:supports various nerworking modes such as point-to-point,chain,ring(Center utility (CU)also supports T shape,cross ring and tangent ring)etc;
    >>Supports various device control modes such as internal loop-back,external loop-back,enable and disable etc;
    >>Provides standard SNMP uniform network management system;
    >>To be managed conveniently; supports inquiry and conflguration of every node and every board in the network through operating panels without help of nerwork management;
    >>Comprehensive and flexible modes of inquiry and configuration:a.panel;b.RS232 hyper terminal(standard TL1 command line);c.RS485 network management software;d.SNMP agent module,displaying through the interface of PC network management software;
    >>Power supply adopts +1 hot standby,taking DC-48V/AC220V/DC-48V+AC220V(dual supply)as options;with an alarm function of remote terminal break-off.
