What the Modem does
The Wireless Voice Gateway provides high-speed Internet access as well as
cost-effective, toll-quality telephone voice and fax/modem services over
residential, commercial, and education subscribers on public and private
networks via an existing CATV infrastructure. It can inter-operate with the
PacketCable compliant head-end equipment and provide the IP-based voice
communications. The IP traffic can transfer between the Wireless Voice
Gateway and DOCSIS/Euro-DOCSIS compliant head-end equipment. The data
security secures upstream and downstream communications.

What the Modem needs to do its job
•
The Right Cable Company: Make sure your local cable company provides
data services that use cable TV industry-standard DOCSIS/Euro-DOCSIS
compliant and PacketCable/Euro-PacketCable compliant technology.
•
The Internet/Telephony Service Provider (ISP/TSP): Your cable company
provides you access to an Internet Service Provider (ISP) and Telephony
Service Provider (TSP). The ISP is your gateway to the Internet and provides
you with a pipeline to access Internet content on the World Wide Web
(WWW). The TSP provides you with telephony access to other modems or
other telephony services over the Public Switched Telephone Network
(PSTN).
