MUMBAI, India, July 21 --

- 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.
