Signaling Market Leader -- PT -- Announces Next-Generation LTE/IMS Diameter Core and Edge Solutions

- Universal Diameter Router Leverages PT's Powerful and Versatile SEGway Platform

NEW ORLEANS, May 7, 2012 /PRNewswire/ -- CTIA Wireless – PT (NASDAQ: PTIX), a leading global supplier of advanced network communications, today announced its Universal Diameter Router (UDR), broadening the company's SEGway Signaling line of IP-native products. UDR provides essential functions of centralized core and edge routing for Diameter Protocol elements widely used in the all-IP, service-oriented, IMS and Long Term Evolution (LTE) architecture networks. These functions include:

• Diameter Routing Agent (DRA) as specified by 3GPP
• Diameter Edge Agent (DEA), the GSMA specification
• Diameter Protocol per IETF specifications
• Interworking Function (IWF) as per 3GPP

As IMS and LTE infrastructures are deployed, new elements such as policy servers, gateways, session controllers, and charging systems are interconnected and interwork via Diameter Protocol to exchange network information. The rapid proliferation of these adjunct network devices, together with the exploding appetite for extreme bandwidths enabled by LTE and IMS, result in the need to manage enormous increases in signaling traffic within the network. The sheer volume and complexity of Diameter traffic places staggering demands on core signaling elements; with SEGway's IP-native, built-for-purpose platform, service providers attain scalable high performance with powerful multi-core processors, 10Gb point-to-point backplane speeds and 40Gb uplink. The flexible routing engine and advanced screening capabilities provide the ability to route and screen on any parameter in the message. Architected for extensibility as well as straightforward evolution to future Diameter applications, this high-powered platform makes SEGway UDR ideal for Next-Generation Network (NGN) deployments.

"The SEGway UDR fully leverages our substantive portfolio of IP-centric and advanced network routing hardware and software technologies with the expertise gained by our long history of deploying carrier grade network solutions," said John Slusser, President and CEO of PT. "It is this unique combination of technology and real-world network experience that results in the SEGway UDR being a best-of-breed solution for a wide range of Diameter signaling requirements in Next-Generation Network architectures."

Patt Rice, PT's Senior VP, Sales, Marketing and Service, commented, "PT has been diligently monitoring the industry to determine the volume and capacity requirements in the Evolved Packet Core as service providers migrate to LTE. Ever mindful of carriers' OPEX concerns, we are convinced PT's UDR is the right solution in the right market conditions. It allows service providers to leverage existing networks' infrastructure on their path to LTE using a richly featured and precision-tuned, cost-conscious platform, avoiding the expense and drawbacks of some early off-the-shelf entries. With SEGway, the Next-Gen service provider benefits through Simply Smarter Signaling, the PT advantage."

PT's SEGway Signaling products are deployed in over one thousand locations, providing the Signaling backbone for many of the world's premier wireless networks. With its small footprint and high throughput capacity, SEGway is widely recognized as the industry's leading signaling architecture, with the ability to scale from small to very large networks.
