PRODUCT OVERVIEW
The Total Access 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 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, and
provides a viable migration path from TDM to packet-
based technology. 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 and eight access slots. Common cards
required for operation are a power supply unit (PSU)
and a system controller. System controllers include a
bank controller unit (BCU) (L1 and L2) and a router
control unit (RCU). The RCU includes a wide area
network interface (T1 or SDSL), DSX-1 PBX interface,
Nx56/64 V.35 interface, and built-in IP 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 (only supported in
the BCU) and ISDN U-BR1TE. The other access slots are
used for Nx56/64 module with the BCU, the Echo
Cancellation card for use with the T1 ATM RCU, and
the DSX-1 card used with the T1 TDM RCU.
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 that only four
analog circuits are affected when replacing a module.
