The Total Access 850 is an integrated access device designed for cost-effective deployment of voice and data services at the customer premises. The Total Access 850 system benefits integrated communications providers, such as CLECs, ILECs, and ISPs, who require a customer premises device that integrates voice and data functions. It provides a viable migration path from TDM to packet-based technology (see Modules on page 18 for details). The Total Access 850 features remote management, an integrated IP router, and special services slots.

The Total Access 850 is a modular device with two common slots, six access slots for FXS, FXO, Dual V.35, and UBR1TE modules, and two slots for special access modules. The FXS, FXO, Dual V.35, and UBR1TE modules are supported in the Router Control Unit (RCU); . Easy access to modules, common modules, power supplies, and the battery back-up system simplifies maintenance procedures. Hot-swappable modules may be replaced without disrupting other units. The four-circuit-per-module design ensures that only four analog circuits are affected when replacing a module. The Total Access 850 is a compact, NEBS compliant cabinet suitable for the customer premises or the central office. The 2U design uses little rack space; or when wall-mounted, the 8½-inch by 11-inch chassis occupies a space the size of a piece of notebook paper.
