P-2002 Series User's Guide Comfort Noise Generation The Prestige generates background noise to fill moments of silence when the other device in a call stops transmitting because the other party is not speaking (as total silence could easily be mistaken for a lost connection). Echo Cancellation The Prestige supports G.168, an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk. QoS (Quality of Service) Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. The Prestige supports Type of Service (ToS) tagging and Differentiated Services (DiffServ) tagging. This allows the Prestige to tag voice frames so they can be prioritized over the network. Fax Tone Detection and Pass-through The Prestige automatically detects fax messages and sends them over PCM G.711. Auto-provisioning Your voice service provider can automatically update your Prestige's configuration via an auto-provisioning server. Auto Firmware Upgrade The Prestige gives you the option to upgrade to a newer firmware version if it finds one during auto-provisioning. Your voice service provider must have an auto-provisioning server and a server set up with firmware in order for this feature to work. Manual Firmware Upgrades Use the web configurator to upload updated firmware to your Prestige. Ease of Installation Your Prestige is designed for quick, intuitive and easy installation. Physically, its compact size and lightness make it easy to position anywhere in your busy office. 1.4 LEDs The following graphic displays the labels of the LEDs. Chapter 1 Introducing the Prestige 25
