and ISPs, who require a customer premises device that integrates voice and data functions, and provides a viable migration path from TDM to packet-based technology. The Total Access 850 features remote management, an integrated IP/IPX router and special services slots.The Total Access 850 is a modular device, with two common slots and eight access slots. Common cards required for operation are a power supply unit (PSU) and a router control unit (RCU). The RCU is a card that currently supports TDM-based applications, but can be easily upgraded to an ATM-based controller as requirements migrate. The RCU includes a T1 network interface, Nx56/64 V.35 interface and built-in IP/IPX router. Six access slots allow the user to combine a variety of voice and data services. Up to six Quad FXS or Quad FXO access modules can be installed to support up to 24 analog voice lines. Other access modules for data applications include the OCU DP and ISDN U-BR1TE. The other two access slots are for future hardware options.Using local or remote inband management, carriers can turn features, functions and access ports on and off. Easy access to modules, common cards, power supplies, and the battery back-up system simplify maintenance procedures. Hot-swappable modules may be replaced without disrupting other units. The four-circuit-per-module design ensures a maximum of only four analog circuits are affected when replacing a module. The Total Access 850 supports several key system features including station-to-station calling, dial-plan entry, local-toll and long distance call routing (based on DTMF digit analysis), and entry and control of flexible routing tables.
