Global Crossing Carries ISDN Video Calls over IP Backbone

Global Crossing is now carrying ISDN calls directly on its private IP backbone rather than the public switched telephone network (PSTN). Calls are then provisioned into multi-point conferencing units (MCU's) that enable multiple sites to communicate simultaneously without additional routing. Global Crossing said videoconferencing calls placed over ISDN networks have traditionally been susceptible to problems such as freeze frames and temporary disconnects. Its newly enhanced videoconferencing service is aimed at multinational organizations. The company has already provisioned more than 406,000 network minutes of enhanced videoconferencing service, linking large multinational corporations with sites in Europe, the America's and Pacific Rim.


Separately, Global Crossing announced a contract to provide audio, video and Web-based conferencing services to the Zurich Financial Services Group.
