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).
Check with your cable company to make sure you have everything you need to begin; they’ll know if you
need to install special software or re-configure your computer to make your cable internet service work for
you.
