We have the largest long-distance telecommunications network in
Latin America providing both national and international connections
to thousands of points throughout Brazil.

We are the main provider of high-speed data transmission
and Internet service in Brazil, with the largest national
network of broadband fiber-optic transmission systems. Our
network has countrywide coverage with 28,388 kilometers of
fiber cables comprising 1,045,617 kilometers of optical fibers
as of the end of 2000. In addition, we use a 100% digital
switching system for voice and data and use packet-switched
data communications, ATM (asynchronous transfer mode) and
frame relay for data and Internet services. We have metropolitan
digital fiber networks in the largest cities in Brazil with
direct fiber or wireless connections to businesses. We are
implementing lateral fiber extensions with commercial buildings
connected to metropolitan rings, providing high quality direct
connections. We continue to expand construction of metropolitan
digital fiber optic networks to additional strategic cities
with a high concentration of business customers. We utilize
digital microwave transmission systems in areas where installation
of fiber cables is less cost effective. We also use satellites
to provide services to remote locations within the country.

domestic long-distance and data network:

We currently own and operate a domestic earth station in
Guaratiba, located in the state of Rio de Janeiro. This station,
activated in 1985, accesses the Brasilsat A2, B1, B2, B3 and
B4 satellites. These satellites cover the entire territory
of Brazil, Argentina, Uruguay and Paraguay and were launched
by Arianespace S.A. The satellites are maintained and monitored
by us through the Guaratiba earth station.

We provide international service primarily through major international
undersea cable systems, which link Brazil with key trading partners.
We have three international digital switches in strategic locations
and employ satellites to provide additional international capacity
and to reach regions of the world where this is the most economical
method. We have direct international network connections via digital
fiber-optic cables and digital radio transmission to Argentina,
Uruguay, Bolivia and Paraguay. To complement and diversify our international
network and increase our global service capacity in a cost-effective
way, we currently utilize satellite leased capacity from the International
Telecommunications Satellite System - Intelsat, an intergovernmental
organization in which we have ownership interest. The satellite
channels are controlled and monitored through our two own earth
station complexes for international service, one located in Tangua
(in the state of Rio de Janeiro) and one located in Morungaba (in
the state of São Paulo). These earth stations, activated
in 1969 and 1986, respectively, access Intelsat satellites positioned
over the Atlantic Ocean with coverage of the entire American continent,
Western Europe, Africa and Middle East.
We own an international submarine cable network that reaches all
continents. In 2000, we added to our Network substantial capacity
with the completion of two new digital cable systems: Atlantis 2,
which connects directly to Europe and Argentina, and Americas II,
which provides a second high capacity link between Brazil and the
United States.
