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
