This technology, for the first time, distributes two-way television-quality video, FM-quality stereo audio, and data to the desktop, meeting room, or classroom over the twisted-pair telephone wires (CAT 3 or better) already available in buildings and on the campus today. The VidModem®

uses the actual twisted pair wiring used by the telephone - not the wiring associated with the local area network (LAN).

VidModem® enables the delivery of three key video services - multipoint videoconferencing, video distribution, and access and retrieval of stored video. Users can simultaneously conduct:

• Two-way, multipoint, television-quality videoconferencing
• Video broadcasts to multiple locations
• Access and retrieval of stored video information (video on-demand)

VidModem® is an enterprise-wide solution capable of interfacing with Wide Area Network (WAN) connections including ATM and ISDN. VidModem® is compatible with any digital, analog, or ISDN PBX, Centrex or Key telephone system, and interoperates with existing H.320 compliant videoconferencing system.

The VidPhone® System runs on PCI-bus Windows 95 and Windows NT workstations.

• Category 3 wiring for distance of 1,000 feet
• Category 5 wiring for distance of 2,000 feet

• Over the existing telephone system wiring already in the building or campus
• Without adding data to the LAN or interfering with normal telephone operation
• Using virtually no PC processing power

VidPhone System

• The VidPhone® System allows people to communicate visually with uncompressed, full-motion video over existing telephone wiring.
• The VidPhone® System integrates in one solution delivery of multipoint videoconferencing, broadcast of satellite or cable TV, and access and retrieval of stored video to desktops and meeting rooms.

VidPhone Switch

• The VidPhone® Switch50 is the multifunction, broadband switch that delivers uncompromising television quality, one and two-way, full-motion video, stereo audio, and data to desktops or meeting rooms.
• The VidPhone® Switch50 is the central hub of the system.

VidPhone Station

• VidPhone® Stations are the user or remote endpoints of the VidPhone® System. Telestar offers a number of VidPhone Stations for desktop, meeting room, observation, and display applications.

Adaptor Cards

• Allow the addition of users and other video sources

Multi-Point Conferencing

• The Conference Bridge4® card allows any VidPhone® Station user to independently initiate and control a multipoint videoconference. It connects any combination of VidPhone® Station, video source, or external CODEC into a videoconference.

WAN Connectivity

• This allows VidPhone® Station users to call other VidPhone® Switches or other H.320 compliant videoconferencing systems over the wide area network.
