said terms couldn't be determined, but Equant has a market capitalization of about $9 billion. Also, the two companies are still discussing financial aspects of the deal such as whether this will be a cash or stock transaction. Equant, which owns an airline reservation system that offers phone and data services, has been on the market for some time and is being encouraged by

SITA

, a consortium of the world's biggest airlines, which wants to get rid of its 33% stake in Equant. Earlier this year, the company was in talks with

France Telecom

(FTE)

and

Global Crossing

(GBLX)

, but negotiations fell through when terms of the approximately $10 billion deal couldn't be agreed upon. Also, about a year ago

quit talks amid concerns of Equant's huge price tag.

For Infonet, the acquisition could realize huge cost savings for the company, which has a similar network, as well as additional customers.
