Business/Technology Editors

FAIRFAX, Va.--(BUSINESS WIRE)--July 11, 2000

ATC Teleports, Inc., a wholly owned subsidiary of American Tower Corporation (NYSE: AMT), Kingston TLI, the international satellite and broadcast arm of the Kingston Communications Group, and EUTELSAT are partnering to offer a new range of cost-effective occasional-use services between Europe and North America using EUTELSAT's Atlantic Gate satellite capacity at 12.5 degrees West.

Starting this month, Kingston TLI is offering both inbound and outbound services between London and the United States. ATC Teleports is providing access to the major US East Coast switches in New York and Washington, D.C. via its Washington, D.C. gateway and fibre network. EUTELSAT's Atlantic Gate capacity offers a high-power Ku-band beam across the Atlantic, connecting major cities on the eastern coast of the USA and Canada with Europe.

Having committed to new antenna systems at its Bedford (UK) Teleport and a massive investment in fibre connectivity this year, Kingston TLI is ideally placed to provide reliable and attractively priced end-to-end occasional use services to broadcasters.

"We believe these services will be unbeatable in terms of flexibility, quality, reliability and value," said Laurence Cook, General Manager, Satellite Services at Kingston TLI. "This is one of our most flexible platforms, and, coupled with the responsiveness of our 24-hour bookings office, will generate high usage from the outset."

"It was always a given that we would provide full bi-directional connectivity to both the New York and Washington switches, as well as turnaround services to and from US domestic satellite systems," he added.

"We're delighted have been chosen by Kingston TLI as their partners for this new and exciting service," said David Liddle, VP, ATC Teleports. "Our recent investment in a dedicated Atlantic Gate antenna underlines our commitment to this new transatlantic route."
