MPEG-2 video sent over twisted pair telephone lines..................
mPhase Technologies Inc. Completes Successful DSL MPEG-2 Video
Technology Trials
NORWALK, Conn.--(BUSINESS WIRE)--February 17, 1998--
Live Demonstration At DTC Communications Proves Conclusively That A Broadcast Quality MPEG-2 Digital Video Picture
and Sound Can Be Delivered Using The Installed Twisted-Pair Public Switched Telephone Network While Simultaneously
Providing Voice and Data
mPhase Technologies (OTC-BB:XDSL) has completed a series of successful point-to-point tests of its unique application
digital subscriber line (DSL) technology.
In the tests conducted at DTC Communications (DTC), in DeKalb County, Tennessee, mPhase Technologies Inc.,
simultaneously transmitted a broadcast quality MPEG-2 (4 Mbps) full motion television picture with sound and standard
telephony service over a single twisted-pair line up to 9,000 feet in length. These DSL tests were conducted at DTC in
November 1997, and are continuing at specific locations selected by mPhase, working in conjunction with local and
international telephone companies.
"The initial demonstrations that mPhase conducted at our facilities were very impressive," said Mr. Wayne Gassaway, general
manager of DTC. He continued, "Utilizing a DVD source programming, MPEG-2 video signals were transmitted over 9,000
feet of randomly selected twisted-pair telephone lines, while operating concurrently and simultaneously within our normal
service switch gear. On the receiving end, I saw a crisp full-motion video with exceptional sound and picture quality."
Mr. Gassaway added, "As an independent telephone company, our future depends on our ability to provide enhanced
telephony services at competitive prices. This is particularly important in many regions of our service area where there is no
Cable TV available. As we continue our test activities with mPhase, our goal is to demonstrate that a local telephone
company, DTC can provide quality video and increased data capacity at a competitive price structure for both business and
residential applications".
To facilitate delivery of program content, mPhase has signed an entertainment delivery contract with Complete
Telecommunications, Inc., located in Nashville, TN. Utilizing a new "branded" program service called Complete TV(R), they
will provide network grade television entertainment for the telco marketplace. The "headend distribution platform" requires the
proprietary video transport and data distribution technology developed in conjunction with Microphase Corporation and
Georgia Tech Research Institute in Atlanta. Commencing in the fourth quarter of 1998, the technology will be utilized to
facilitate initial delivery of an extensive package of cable programming services, local broadcast signals and ancillary services
such as Internet access.
"This technology was specifically designed for telephony applications," said Thomas A. Murphy, chief technology officer and a
co-founder of mPhase. He added, "By focusing our technology at the copper infrastructure telco markets, we can satisfy a
tremendous current need for unsurpassed new telephony based communication applications, as well as rapidly developing a
significant presence in the emerging data, Internet and entertainment delivery market."
Technology Backgrounder for mPhase Technologies Inc.
The combined mPhase/Georgia Tech effort has been designed and structured to perform as an interactive master distribution
platform, capable of delivering up to 256 Channels of MPEG-2 quality television, megabit Internet access, and conventional
telephone service. All of these services can be provided simultaneously over a single twisted-pair line. The performance
objective for the basic delivery system is to provide a full complement of service at 16,000 feet from a central office location.
To facilitate the extended range utilization of mPhase's delivery system, mPhase has accelerated its test activities to incorporate
high performance DSL repeaters. mPhase estimates that its repeaters will provide extended performance beyond the 18,000
feet level with the same level of service.
"The experience and engineering talent available through our strategic alliances with Georgia Tech Research Institute and
associations with companies, such as Microphase Corporation and Globespan Semiconductor, Inc., have all played an
essential part in design and development program, said Murphy. "Their innovative design skills and research capabilities have
provided significant contributions to mPhase's total design, testing, manufacturing standards program as well as our
time-to-market deployment strategy."
mPhase Technologies Inc., designs, develops, manufactures and markets a cost effective, proprietary, end-to-end solution for
delivering digital video and data over the installed, public switched telephone networks. (OTC-BB:XDSL)
