MUMBAI, India, July 21 /PRNewswire/ --

- Wholesale 10 Gigabit Ethernet Now Available in 25 Cities and 11 
Countries

Tata Communications, a leading provider of a new world of
communications, today announced the launch of a new 10 Gigabit Ethernet (10
GigE) service to help service providers meet growing market demands for
high-speed, secure and cost-effective bandwidth.

As part of Tata Communications' extensive Ethernet services
portfolio, 10 GigE leverages Tata Communications' global network to satisfy
large-scale, wholesale needs for high-speed Ethernet technology across the
Atlantic and Pacific and within Asia including India. Available in 25 major
cities in 11 countries worldwide, the service connects all key business
centers over the self-owned TGN (Tata Global Network) cable system.

"Tata Communications' 10 GigE service is a cost-effective
alternative for customers who need large bandwidths on a truly global scale.
Our availability in 25 cities worldwide is unmatched in the industry," said
John Hoffman, Head of Ethernet Services for Tata Communications. "This
service gives customers the flexibility of using LAN Phy or WAN Phy
interfaces. Most customers desire LAN Phy interfaces to further reduce costs
but not all providers can offer these LAN Phy interfaces to their customers."

Hoffman added, "No other telecommunications company can offer
dedicated 10 Gig Ethernet on a global scale. Our expansive suite of Ethernet
Services establishes Tata Communications as a single source provider and
global leader of Ethernet. Utilizing our fully self-owned system of cables
further differentiates Tata Communications from our competitors."

10 GigE helps service providers reduce operational costs
without sacrificing quality. With a transparent pipe offering both LAN Phy
and WAN Phy interfaces, 10 GigE features full-service frame transparency with
no Quality of Service (QoS) restrictions. Frames are forwarded in the order
received, ensuring all customer traffic flows in order and without
restriction. Additionally, customers may choose between protected or
unprotected circuits. The service, which features MEF 6.1 defined Ethernet
Private Line (EPL) point to point configuration so that customers' data is
isolated and travels on its own Ethernet pipe, is a truly dedicated, secure
service.

The 10 GigE service integrates seamlessly with Tata
Communications' global network infrastructure including regional cable
systems such as TGN-Atlantic, TGN-Northern Europe, TGN-Western Europe, TGN-
Pacific and TGN-TIC and new investments like the TGN-Intra Asia Cable-a 6,700
km multi-terabit cable system that connects Singapore, Hong Kong, and Japan;
and the TGN-Eurasia Cable-providing express connectivity between India and
Europe. Combining all these Tata-owned cables, Tata Communications can
provide 10 GigE services literally around the world.

"The ability to deliver 10GigE service on a global scale makes
Tata Communications stand out in the global Ethernet services market," said
Soh Siow-Meng, senior analyst for Global Telecom Services at Current
Analysis. "Service providers looking for a cost-effective option to meet the
increasing demand for international bandwidth will find Tata Communications'
new service attractive."
