2. PRODUCT OVERVIEW

The TA 850 system (see Figure 1) is an integrated access device designed for cost-effective deployment of voice and data services at the customer’s premises. The

TA 850 system benefits integrated communications providers, such as CLECs, ILECs, 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 TA 850 features remote management, an integrated IP/IPX router, and special services slots.

The TA 850 is a modular device, with two common slots and eight access slots. Common cards required for op- eration are a power supply unit (PSU) and a router con- trol unit (RCU). The RCU is a card that currently supports TDM-based applications, but can be easily up- graded to an ATM-based controller as requirements change. The RCU includes a T1 network interface, DSX-1 PBX interface, Nx56/64 V.35 interface, and built- in IP/IPX router. Six access slots allow the user to com- bine 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 mod- ules for data applications include the OCU DP and ISDN U-BR1TE. The other two access slots are for fu- ture 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 sup- plies, and the battery back-up system simplify mainte- nance procedures. Hot-swappable modules may be replaced without disrupting other units. The four-cir- cuit-per-module design ensures that only four analog circuits are affected when replacing a module.

A compact, NEBS-compliant cabinet suitable for the customer premises or the central office provides added safety and reliability. The 2U design uses little rack space. When wall mounted, the 8.5-inch by 11-inch
