Ukraine
general assessment: Ukraine's telecommunication development
plan emphasizes improving domestic trunk lines, international
connections, and the mobile-cellular system
domestic: at independence in December 1991, Ukraine inherited a
telephone system that was antiquated, inefficient, and in disrepair;
more than 3.5 million applications for telephones could not be
satisfied; telephone density is rising and the domestic trunk system
is being improved; about one-third of Ukraine's networks are digital
and a majority of regional centers now have digital switching
stations; improvements in local networks and local exchanges
continue to lag; the mobile-cellular telephone system's expansion
has slowed, largely due to saturation of the market which has
reached 120 mobile phones per 100 people
international: country code - 380; 2 new domestic trunk lines are a
part of the fiber-optic Trans-Asia-Europe (TAE) system and 3
Ukrainian links have been installed in the fiber-optic
Trans-European Lines (TEL) project that connects 18 countries;
additional international service is provided by the
Italy-Turkey-Ukraine-Russia (ITUR) fiber-optic submarine cable and
by an unknown number of earth stations in the Intelsat, Inmarsat,
and Intersputnik satellite systems
United Arab Emirates

integrated services; digital network with rapidly growing use of
mobile-cellular telephones; key centers are Abu Dhabi and Dubai

Indian Ocean), 1 Inmarsat (Atlantic Ocean region), and 1 Eutelsat;
at least 8 large international switching centers
United States
general assessment: a large, technologically advanced,
multipurpose communications system
domestic: a large system of fiber-optic cable, microwave radio
relay, coaxial cable, and domestic satellites carries every form of
telephone traffic; a rapidly growing cellular system carries mobile
telephone traffic throughout the country
international: country code - 1; multiple ocean cable systems
provide international connectivity; satellite earth stations - 61
Intelsat (45 Atlantic Ocean and 16 Pacific Ocean), 5 Intersputnik
(Atlantic Ocean region), and 4 Inmarsat (Pacific and Atlantic Ocean
regions) (2000)
Uruguay

exchanges; mobile-cellular services are growing rapidly, with the
subscriber base exceeding 16 million in 2009
international: country code - 998; linked by fiber-optic cable or
microwave radio relay with CIS member states and to other countries
