Tata Communications Completes Successful 'Real World' Technical and Commercial GSMA IP eXchange Trial

Mumbai, India (ots/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.
