Total Access 850 System Manual Section 1 System Description

1. SYSTEM OVERVIEW

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. Preconfigured Total Access 850 packages are available.

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); however, the Bank Controller Unit

(BCU) also supports E&M, OCU DP, Single DS0 DP, and Nx56/64 modules. Using local or remote inband

management, carriers can turn features, functions, and access ports on and off. 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 wallmounted, the 8½-inch by 11-inch chassis

occupies a space the size of a piece of notebook paper. Two Total Access 850 systems can be mounted

side-by-side in either 19-inch or 23-inch relay racks.
