Rapidly Expands New Diameter Network Across U.S. and European Tier One Operators and Hubbers

BARCELONA, SPAIN--(Marketwire - May 17, 2012) - LTE World Summit Booth #85 -- Ten new customers -- six mobile operators and four hubbers -- have selected Tekelec's Diameter Signaling Router (DSR) since the beginning of March. The wins more than double Tekelec's DSR footprint and bring the customer count to 19 across 10 countries. The company also announced today its Over-the-Top solution for the New Diameter Network.

The DSR, the central nervous system of the New Diameter Network, helps operators manage mobile data and signaling growth and profit from mobile data services. The product securely and efficiently delivers messages controlling network policies, charging data, mobility management and authorization -- all of which traverse networks using the Diameter protocol.

The new customers include tier one operators in Europe and the U.S., a U.S. tier two operator and four hub providers. The 19 total customers are comprised of 14 operators across Asia Pacific, Europe, and the Americas, including multiple national properties in one of the operators, and five hub providers.

All 19 customers will use the DSR to route Diameter messages in the network core. One U.S. tier one made two separate core network routing purchases: one for its LTE network and one for its IMS network. In addition, 11 DSR customers have selected the product to act as a secure interconnection point for roaming between partner networks, and four will also use it to intelligently scale policy deployments to enable usage-based services.

Two U.S. tier one customers selected the DSR to provide the subscriber locator function (SLF) in the LTE architecture that maps between a subscriber identity and a Home Subscriber Server (HSS), a database of subscriber profile information. One of these operators also purchased a DSR system to provide the SLF in an IMS network. Another customer will scale its 3G and LTE charging systems with the DSR.

Cumulatively, Tekelec's customers are deploying the Diameter Signaling Router to support 3.1 million messages per second, a measure of peak traffic capacity, across more than 70 nodes.

"Tekelec's steady customer growth argues that market demand for Diameter signaling control solutions is urgent and global," said Peter Jarich, service director with market intelligence firm Current Analysis. "At the same time, it also tells us that in the early days of the Diameter Signaling Control market, Tekelec's DSR is effectively delivering on service provider requirements."

"The Diameter Signaling Router is the strategic control point for managing data and signaling traffic growth as well as new revenue models like 'toll-free' data and loyalty programs," said Ron de Lange, president and CEO of Tekelec. "Operators are recognizing the value of a holistic New Diameter Network approach and building their new LTE networks with Diameter logic from the ground up."
