P-2002 Series User's Guide CHAPTER 1 Introducing the Prestige This chapter introduces the main features and applications of the Prestige. 1.1 Prestige VoIP Analog Telephone Adaptor Overview The Prestige 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. 1 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. 1. Some features documented in this user's guide were not available in the Prestige 2002L at the time of writing. Chapter 1 Introducing the Prestige 23
