Getting To Know Your Prestige
This chapter describes the key features and applications of your Prestige.
1.1 Introducing the Prestige
The Prestige P2602HW ADSL VoIP IAD (Integrated Access Device) combines high-speed
ADSL Internet access, a 4-port Ethernet switch, IEEE 802.11g wireless access, and Voice
over IP (VoIP) communication capabilities. It is ideal for small networks.
VoIP is the sending of voice signals over the Internet. The Prestige lets you use a traditional
analog telephone for VoIP calls. You can call any landline or mobile telephone as well as IP
telephones (depending on your VoIP service provider). Calls received from IP telephones
work exactly as you would expect from the traditional telephone service. The Prestige uses
SIP (Session Initiated Protocol), an internationally recognized standard for implementing
VoIP.
Note: The Prestige is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks. The Prestige is an ADSL router compatible
with the ADSL/ADSL2/ADSL2+ standards. Maximum data rates attainable by
the Prestige for each standard are shown in the next table.
Note: The standard your ISP supports determines the maximum upstream and
downstream speeds attainable. Actual speeds attained also depend on the
distance from your ISP, line quality, etc.
By integrating DSL and NAT, the Prestige provides ease of installation and Internet access.
The Prestige is also a complete security solution with a robust firewall and content filtering.
Three Prestige models are included in this user’s guide at the time of writing. In the Prestige
product name, “H” denotes an integrated 4-port switch (hub) and “W” denotes an internal
