1-2 Administration Guide
An IAD combines the voice telephony features of a telephone PBX system with the data routing features of an IP
data router. The device uses a single outside line connection to carr y all voice and data transmissions. If the
device uses a DSL inter face, it can carr y all of these ser vices over a single existing copper telephone line by
using the different frequency ranges available on the copper wire for voice and data traffic.
The Netopia 4752 SDSL Integrated Access Device is that device: a Centrex-based PBX system combined with
an SDSL internet router.
The Netopia 4752 SDSL 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 inter face to learn.
Centrex support. Advanced telephone features enabled by your ser vice provider's telephone switch such as
call for warding or conferencing operate exactly as they did before.
Netopia data routing engine. Provides the same advanced, business-class data routing features used by
leading DSL ser vice providers around the world. Includes advanced data functionality such as firewall, VPN
client and ser ver (including PPTP and IPSec), DHCP automated address assignment, and Network Address
Translation (NAT and MultiNAT).
