  Very Small Aperture 1 Terminal (VSAT)


  VSATs are earth terminals using small antennas 2 (1.5 6 feet in diameter). This technology typically operates in the Ku band (11/14 GHz), and Ka band (20/30 GHz).


  Video Conferencing


  Video conferencing is the real-time, usually two-way transmission of voice and images between two or more locations. Today, both voice and video analog 3 signals are digitized by video codices before transmission which can involve wide bandwidths. To conserve 4 bandwidth, some systems employ "freeze frame," where a television screen is only "repainted" every few seconds. Codecs for higher quality full motion video attempt to minimize bandwidth requirements by taking advantage of intervals 5 with relatively 6 little motion (which require smaller bandwidths), and by trading off smooth motion tracking and picture resolution.


  Virtual Private Networks (VPN)


  VPNs are services using public network facilities augmented 7 by network control point and service management system facilities wherein traffic is routed through the public network under computer control in a manner that makes VPN service indistinguishable from dedicated 8 facilities based private networks. Customers can define, change and control network resources with the same or more flexibility 9 as afforded by facilities based private networks.
