Cisco Systems Inc. (San Jose, CA) and General Instrument Corp. (Horsham PA) intend to work with AT&T (Morristown, NJ) on a non-exclusive basis to develop and trial a seamless, end-to-end Internet protocol (IP) solution that would allow AT&T to offer data, voice and video services over its hybrid fiber-coaxial cable (HFC) network now being deployed. Although specific agreements have not been reached, the Cisco/General Instrument IP telephony solution under development would allow AT&T to offer its customers the ability to simultaneously watch television, send and receive faxes, surf the World Wide Web, and talk on the telephone.
