HACKENSACK, NJ -- November 7, 1997 -- IDT Corporation (NASDAQ: IDTC), a leading provider of low-cost international telecommunications, today announced that it has signed an $8 million agreement with Global Telesystems Ltd. to acquire an indefeasible right of use (IRU) on transatlantic cable between the US and UK on the Atlantic Crossing (AC1) cable network. The new route will be connected to the existing IDT telecom network, and is a critical step toward achieving the Companyís strategic initiative of expanding its worldwide telecom infrastructure.

The Company expects to begin routing traffic over the new cable network by June 1998, which is expected to result in significantly reduced operating costs, improved margins, and decreased terminating rates. This new acquisition further establishes IDT as a fast-growing international carrier.

The purchase of the STM-1 cable, which is equivalent to three DS3ís (155 megabits of capacity), replaces leased circuits between the US and UK, and is expected to reduce the transatlantic portion of the costs by a substantial magnitude. The cable will provide more than 10 times the current leased capacity. The Company has also secured favorable financing commitments, and intends to expand its cable network throughout 1998 with fiber connecting the UK and additional European countries. This purchase will also provide the Company with an expanded UK facility that will mirror IDTís US facilities from a management, technical, and cost perspective, and gives the Company a strong beachhead in the European market, which will position the Company well to compete with the European telcos as those markets deregulate in the coming year.

"Buying the right to use these routes allows us to improve service and quality for IDT customers and will help us further emerge as an industry leader," said IDT President Jim Courter. "This agreement will enable IDT to route more traffic over our own network, decrease our cost structure, improve gross margins, and will result in quicker provisioning for both wholesale and retail customers. We look forward to continuing to expand our worldwide telecommunications network in the coming quarters."

The Atlantic Crossing cable system combines state-of-the-art wavelength division multiplexing with erbium-doped fiber amplifier technology, making it the most powerful cable system and assuring customers capacity on demand. AT&T (NYSE: T) signed an agreement with AC1 earlier this year to build this cable network.
