BOSTON, Massachusetts, August 6 /PRNewswire/ --

- Initial Orders Under the Frame Agreement With Global Tier-1 Group Worth
Approximately US$5 Million

Allot Communications Ltd. (NASDAQ: ALLT), a leader in IP service
optimization and revenue generation solutions based on deep packet inspection
(DPI), announced today a framework agreement with a global tier-1 mobile
operator group. Initial orders received are worth approximately five million
US dollars. The initial order includes the widest global deployment of Allot
Service Gateway to date. In the current deployment, the Allot solution is
being installed with local operators in a number of countries which
collectively service more than 60 million voice subscribers.

The 3GPP mobile standard compliant solution is designed to ensure fair
use network management and maximize subscriber quality of experience (QoE).
The solution enables the operator to intelligently manage the network
resources and optimize bandwidth utilization while giving each subscriber
equal access to the network. Key to the solution is Allot's unique subscriber
and application awareness technology which enables real-time identification
of the traffic, giving the operator real-time visibility into the behavior of
their own network.

"This deal has the potential to significantly change the way the mobile
market offers subscriber services," said Rami Hadar, Allot's CEO and
President. "Mobile broadband is growing beyond the industry's wildest
expectations, and the current challenge for operators is to deploy reliable
solutions that readily integrate into their networks and help them manage
this data traffic explosion, as well as develop new revenue opportunities
going forward. Allot has both the experience and expertise to meet these
challenges head on."
