Global Crossing is decommissioning the first legacy time-division multiplexing (TDM) switch in the core of its network. The first TDM switch to be taken out of service is in Chicago, and the company plans to remove additional switches later this year and in 2005.
Global Crossing said VoIP traffic traversing its private backbone grew to as much as 2.4 billion minutes each month, or approximately 40% of its total voice traffic. Global Crossing is using Sonus Networks' VoIP platform.
Global Crossing's Carrier VoIP Service, introduced in September 2003, provides carrier IP interconnection, transport and call completion of packet-based voice traffic over Global Crossing's integrated IP and TDM platforms. Customers can call around the globe, utilizing Global Crossing's service network connecting 500 cities in 50 countries on 6 continents. Security is ensured since the VoIP traffic traverses the MPLS-based IP backbone, with additional firewall functionality provided by the session border controllers, connecting the VoIP platform to IP-VPN customers, extending voice services natively over IP. http://www.globalcrossing.com
- Earlier this year, Global Crossing announced three new enterprise VoIP services that delivered over its private MPLS network. The new offerings include: "VoIP Outbound", "VoIP Toll Free" and VoIP On-net Plus". The new offerings enhance Global Crossing's existing VoIP On-net Transport service, which enable enterprises to use an IP VPN to eliminate traditional long distance and international long distance charges for their managed dial plans.
