This illustration shows a cable company that offers DOCSIS- and PacketCable-compliant
voice/data services.
1. How does the gateway work?
The Advanced Cable 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 headend equipment and provide the IP-
based voice communications. The IP traffic can transfer between the Advanced Cable
Gateway and DOCSIS compliant headend equipment. The data security secures upstream and
downstream communications.
2. What do you need to enjoy all services?

The Right Cable Company: Make sure your local cable company provides data
services that use cable TV industry-standard DOCSIS compliant and 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).
