A component of the Total Access System,
Total Access 850

®

is a completely modular

Carrier Class integrated access device
designed for cost-effective deployment and
seamless integration of combined services at
the customer’s premises.

The Total Access 850

provides enterprise users and integrated com-
munications providers, such as CLECs, ILECs,
and ISPs, a viable migration path from TDM to
packet-based technologies, including VoATM
and VoDSL.

The Total Access 850 has two common slots

and eight access slots allowing the customer to
combine a variety of voice and data services
into a single platform. Two common cards, the
power supply unit (PSU) and the router control
unit (RCU), are required for operation. The
RCU supports TDM-based applications and
can be easily upgraded to support packet-
based applications. The RCU activates several
user interfaces on the Total Access 850 chassis
including the network interface, the Nx56/64
V.35 interface for synchronous data applica-
tions, and the integral IP router. Up to six Quad
FXS or Quad FXO access modules can be
installed to provide support for up to 24 analog
voice lines. These analog interfaces support the
stringent design and full feature set required by
today’s carrier, including popular CLASS

features. The VoDSL and VoATM implementa-
tions found in the Total Access 850 are
compatible with industry-leading VoBB
Gateways. Access slots A and B are available 
for hardware options such as echo cancella-
tion/ADPCM support. 

The Total Access 850 is housed in a rugged

metal chassis and provides the flexibility
needed for quick turn-up in harsh environ-
ments. Easy access to modules, common cards,
and power supplies simplifies maintenance
procedures. Hot-swappable access modules
can be replaced without disrupting service to
the entire system. An optional ADTRAN battery
backup system is available for added security.

The integrated IP router provides a powerful

suite of performance and security features. For
simultaneous access to the corporate network
and the ISP, the Total Access 850 offers multiple
PVC configurations. Supporting NAT/PAT and
packet filtering, the Total Access 850 secures the
corporate network from unwanted intrusion. 

In a compact, NEBS-compliant chassis, 

the Total Access 850 provides the added safety
and reliability suitable for the customer prem-
ises or the central office. About the size of a
standard piece of notebook paper, the 8.5-inch
by 11-inch 2U chassis minimizes rackmount
and wallmount space. Two Total Access 850
systems can be mounted side-by-side in either
19- or 23-inch racks. Pre-configured mounting
packages are available. For network access, the
Total Access 850 has a single T1 or SDSL inter-
face that is compatible with today’s
industry-leading DSLAMs. In addition to all of
these features, the Total Access 850 is backed by
an industry-leading 10-year warranty and
ADTRAN’s 24-hour technical support.
