MUMBAI, India, February 5 /PRNewswire/ --

- TELUS and Telekom Austria Participate to Set Standards for Telecommunications Industry

Tata Communications, a leading provider of a new world of communications, announced today that it has successfully completed trials of its wireless IP interconnection technology, part of the international GSM Association's program to develop the next generation of wireless services. The Tata Communications trial verified its IP eXchange framework can interconnect wireless networks over IP, which is more efficient and flexible than the traditional Time-Division Multiplexing technology.

Tata Communications' trials were part of the GSMA's IP eXchange (IPX) Pre-Commercial Implementation Project, which is verifying the design and operation of IPX networks through a series of trials designed to validate technical and commercial specifications. Once adopted, IPX will act as a private global IP backbone, open to any telecommunications company adhering to the required standards. IPX will provide fixed and mobile service providers with a technical and commercial platform for the performance-based exchange of IP-based services.

Tata Communications' participation and completion of the GSMA's IPX trial is key to our strategy of delivering innovative voice solutions to our customers worldwide, said Michel Guyot, President, Global Voice Solutions for Tata Communications. Our company is committed to working with the IPIA (IP Internetworking Alliance) to promote and support the launch of IPX services and is planning to launch its own IPX rich, integrated offering to service providers - like TELUS and Telekom Austria - delivered over next-generation network architecture. We truly believe the IPX model will have a very significant impact on the industry.

In the trial, Tata Communications partnered with Canadian telecommunications company, TELUS and Telekom Austria to successfully interconnect voice services using different signaling and transmission standards. The trial demonstrated the flexibility of Tata Communications' newly-deployed NGN network by bridging voice over IP services using several very different standards. The trial demonstrates that Tata Communications, with its unique global footprint and service capabilities, can commercialize IPX Voice Services.

TELUS is committed to delivering the best possible service experience for our clients, said Brent Allison, vice-president of TELUS Partner Solutions. These IPX standards give us a new technical and commercial model for the migration of voice traffic to converged IP networks. We were pleased to play a key role with a valued partner like Tata Communications in this industry-leading IP initiative.

The IPX trial is a key component of a series of strategic activities that Tata Communications are engaged in to enable the company to deliver benefits to it customers ranging from its far-reaching signaling network to managing the growing volume of fixed and mobile VoIP traffic. With the growth of IP communications, the IPX model is crucial for service providers such as Tata Communications to offer effective connectivity and significant expertise in handling and servicing service providers.
