The Netopia 4741 Voice/Data Integrated Access Devices (IADs) make it possible for small businesses to take
advantage of the advanced communications technologies previously limited to larger organizations. By
integrating multiple voice connections and high-speed Internet access on one DSL line, businesses can
squeeze the most out of their communications budget.
The Netopia 4741 ADSL Integrated Access Device combines a complete telephone system with a
business-class data router to deliver a customized package of business communications services over DSL.
The Netopia 4741 supports the broad array of phone features offered through your service provider and uses
your existing analog telephone equipment. The Netopia 4741 includes Netopia's sophisticated data routing
engine optimized for small and medium size business needs. These business-class features include IP routing,
firewall, NAT, MultiNAT, DHCP and both PPTP and IPSec VPN functionality.

Small- to medium-sized businesses need two kinds of services: Internet presence and voice telephony. But they
don't need the additional burden of maintaining switching equipment or administering IP and voice services for
their offices. An Integrated Access Device (IAD) that offers high-speed DSL for IP connectivity and a voice
telephone system that somebody else (the phone company) administers is the simple solution.
At the phone company's central office, where all the big switch gear is, there are two kinds of switches for the
two kinds of services, voice and data. The IAD must be capable of communicating with a wide array of possible
combinations of voice and data switches.
An IAD combines the voice telephony features of a telephone system with the data routing features of an IP
data router. The device uses a single outside line connection to carry all voice and data transmissions. If the
device uses a DSL interface, it can carry all of these services over a single existing copper telephone line by
regulating the flow of voice and data packets on the copper wire for voice and data traffic.
The Netopia 4741 ADSL Integrated Access Device is that device: a Centrex-based system combined with an
ADSL internet router.
The Netopia 4741 ADSL Integrated Access Device provides the following features:
Support for ordinary analog phone equipment. Works with the same FXS analog phone sets and key systems
that small businesses use today. No expensive handsets to order, no new interface to learn.
Centrex support. Advanced telephone features enabled by your service provider's telephone switch such as
call forwarding or conferencing operate exactly as they did before.
