Prestige 2602R Series User’s Guide

Chapter 1 Getting To Know Your Prestige 36

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) and Differentiated Services (DiffServ). This allows

the Prestige to tag voice frames so they can be prioritized over the network.

SIP ALG

The Prestige 2602R is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass

through NAT.

Auto-provisioning

Auto-provisioning automatically updates your Prestige’s configurable settings via a TFTP

server.

High Speed Internet Access

Your Prestige ADSL/ADSL2/ADSL2+ router can support downstream transmission rates of

up to 24Mbps and upstream transmission rates of 3.5Mbps. Actual speeds attained depend on

ISP DSLAM environment.

Zero Configuration Internet Access

Once you connect and turn on the Prestige, it automatically detects the Internet connection

settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes

the necessary configuration changes. In cases where additional account information (such as

an Internet account user name and password) is required or the Prestige cannot connect to the

ISP, you will be redirected to web screen(s) for information input or troubleshooting.

Any IP

The Any IP feature allows a computer to access the Internet and the Prestige without changing

the network settings (such as IP address and subnet mask) of the computer, when the IP

addresses of the computer and the Prestige are not in the same subnet.

Traffic Redirect

Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect

to the Internet, thus acting as an auxiliary if your regular WAN connection fails.
