Introducing the Prestige
This chapter introduces the main features and applications of the Prestige.
1.1 Prestige 2002 VoIP Analog Telephone Adaptor Overview
The Prestige 2002 is a SIP-based VoIP analog telephone adaptor (ATA). Sending voice
signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an
internationally recognized standard for implementing VoIP.
The Prestige allows you to use a traditional analog telephone to make and receive Voice over
IP calls. You can call any landline or mobile telephone as well as IP telephones. You don’t
need to know if the recipient’s connection type is an IP, cellular or landline based service.
Calls received from IP telephones work exactly as you would expect from the traditional
telephone service.
The Prestige’s two Ethernet ports allow you to connect the Prestige to your LAN and connect
your computer to the Prestige. This way your computer can still access the LAN without
adding an extra Ethernet switch.
The Prestige's web configurator allows easy management and configuration.
1.2 Prestige 2002L VoIP Analog Telephone Adaptor with
Lifeline
The Prestige 2002L has all of the features of the Prestige 2002 and adds the PSTN (Public
Switched Telephone Network) lifeline feature. PSTN lifeline lets you have VoIP phone
service and PSTN phone service at the same time.
1.3 Features
Your Prestige is packed with a number of features that make it flexible and easy to use.
10/100Mbps Auto-negotiating Fast Ethernet Interfaces
The auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions
and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps
or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Auto-crossover 10/100 Mbps Ethernet Interfaces
The Ethernet interfaces automatically adjust to either a crossover or straight-through Ethernet
cable.
