with a microwave
radio transmitting and receiving antenna and required receiving and
transmitting equipment for communicating with satellites

satellite link--a radio connection between a satellite and an earth
station permitting communication between them, either one--way (down
link from satellite to earth station--television receive--only
transmission) or two-way (telephone channels)

SHF--super--high--frequency; any radio frequency in the 3,000- to
30,000-MHz range

SHF--super-high-frequency; any radio frequency in the 3,000- to
30,000-MHz range

Solidaridad-geosynchronous satellites in Mexico's system of
international telecommunications in the Western Hemisphere

Statsionar--Russia's geostationary system for satellite
telecommunications

submarine cable--a cable designed for service under water

TAT--Trans--Atlantic Telephone; any of a number of high--capacity
submarine coaxial telephone cables linking Europe with North America

telefax--facsimile service between subscriber stations via the public
switched telephone network or the international Datel network

telegraph--a telecommunications system designed for unmodulated
electric impulse transmission

telex--a communication service involving teletypewriters connected by
wire through automatic exchanges

tropospheric scatter--a form of microwave radio transmission in which
the troposphere is used to scatter and reflect a fraction of the
incident radio waves back to earth; powerful, highly directional
antennas are used to transmit and receive the microwave signals;
reliable over-the-horizon communications are realized for distances up
to 600 miles in a single hop; additional hops can extend the range of
this system for very long distances

trunk network--a network of switching centers, connected by
multichannel trunk lines

UHF--ultra-high-frequency; any radio frequency in the 300- to
3,000-MHz range

VHF--very-high-frequency; any radio frequency in the 30- to 300-MHz
range
