EL SEGUNDO, Calif.--(BUSINESS WIRE)--Oct. 23, 2003

Agreement Helps Traveling Employees Connect Safely To Their

Data Network From Any Location

Infonet Services Corporation (NYSE: IN), a leading provider of global communications services for multinationals, today announced that Siemens Business Services has partnered with Infonet to manage its customers' data communications requirements.

The Siemens Business Services solution CORINA (Corporate Remote Intranet Access) allows traveling employees to dial into their company's data network from their laptops at any location worldwide using various methods, such as analogue connections, ISDN, cell phones, the Internet, and Wireless LANs.

Using CORINA, remote users click on their respective location on a graphical interface, and the connection to a Siemens Business Services dial-in node in Germany will automatically be established via Infonet's global IP network and DialXpress(R), Infonet's industry-leading remote access service. This is where the user authentication takes place, and the call is forwarded to the destination. With that, Siemens Business Services offers a complete end-to-end encryption with strong authentication.

"More and more of our customers' mobile managers, sales representatives and service technicians need to access their company's data network at any time and at any location. CORINA is managing this communication in a secure and comfortable way," said Thomas Lichtenberger, Head of Carrier Management at Siemens Business Services.

To ensure a secure dual source strategy, Siemens Business Services placed a new Request for Proposal for international data communications this past year. After considering six global providers, Siemens Business Services chose Infonet as the CORINA mainline partner.

"Infonet is offering us significantly more free call facilities as a value add and is additionally providing the accompanying data tracking where, when and how long the user is online," Lichtenberger emphasized. "With that, we can offer more simplified application facilities to our customers as well as the exact accounting information they need to adequately divide associated expenses among responsible parties. In places where we work with a flat rate, this helps us calculate expenses considerably more accurately. With this, we have significantly strengthened our market position in this segment."

Siemens Business Services additionally highlighted Infonet's favorable price performance ratio and high flexibility as criteria that helped make the decision to utilize Infonet.

"Our global presence, innovative technology and our flexible project management have, one more time, tipped the scales for a strategic decision in our favor," said Micheline Wens, General Manager at Infonet Network Services Deutschland GmbH in Frankfurt, Germany.

Around 40 countries will be migrated to Infonet's global network. The transfer volume in this segment of the Siemens Business Services network approaches 600,000 minutes a month, with about half of that data traffic coming from within the Siemens group and its external customers.

"When designing the CORINA solution, we attached great importance to security in the network as well as on the customer's premises hardware, and also to the ability to integrate new access methods (like 3G), as well as being able to provide user friendly ergonomics," said Michael Wurzer, Manager of the Competence Center for Local Networks and Mobile Access at Siemens Business Services.

CORINA consists of a graphical interface at the laptop, the authentication, security and administration systems to the Siemens Business Services dial-in node in Munich, Fuerth and Paderborn, and the related external communications services. It can only be accessed with a PIN and a SecurID card, whose code changes every 60 seconds. In the near future, digital certificates will also be supported for authentication.

DialXpress, which was recently named a World Communication Awards finalist for "Best Managed Service", is a fully managed and globally available remote access solution into Infonet's The World Network(R). There are no fixed line charges for the respective locations.
