BOSTON, Massachusetts, June 2, 2010 /PRNewswire/ -- Allot Communications Ltd. , (http://www.allot.com/) a leading supplier of service optimization and revenue generation solutions for fixed and mobile broadband service providers worldwide, today announced a deal with a Tier-1 fixed operator for $4.5 million. The operator has bought Allot solutions based on the Company's flagship product, the Allot Service Gateway Sigma (SG-Sigma) (http://www.allot.com/Service_Gateway_Sigma.html). The SG-Sigma maximizes network efficiency and performance and improves the user experience by integrating network intelligence, policy control, and revenue-generating services in a single platform.

This multi-site deployment is intended to initially handle more than 1 terabit of traffic. The SG-Sigma's superior bandwidth management capabilities will enable the operator to extract more comprehensive intelligent information from the network and use this information to optimize network performance. This will result in better management of existing network resources, thereby offering the subscribers an improved and more personalized experience.

This win is further proof of SG-Sigma's superior capabilities and its standing as the operator platform of choice, both for fixed and for mobile broadband networks, said Rami Hadar, Allot's President CEO.
