Performance and Capacity Increases Provide a Cost-Effective Means to Grow Subscriber Base While Positioning the Network to Accommodate New and Emerging Services

Acme Packet® (NASDAQ: APKT), the leader in session border control solutions, today announced that O1 Communications, a leading California-based provider of wholesale VoIP solutions, has deployed Acme Packet’s Net-Net® 4500 to expand their SIP peering services to enable service providers to originate and terminate voice calls throughout California via a single IP connection.

The Net-Net 4500, deployed by O1 Communications as a session border controller (SBC), provides secure and seamless interconnection of IP networks for multiple services and applications offered to small and medium-sized enterprises throughout the West Coast and to service providers worldwide.

The Net-Net 4500 is a recently-announced addition to the Net-Net 4000 series that increases performance and capacity by 100% or more in SBC, multiservice security gateway (MSG) and session routing proxy (SRP) product configurations. Positioned between the Net-Net 4250 and Net-Net 9200 in terms of price, performance and capacity, the Net-Net 4500 satisfies service provider, large enterprise and contact center requirements at both network access and interconnect border points.

Enhancements offered by the Net-Net 4500, as compared to the Net-Net 4250, its companion system in Acme Packet’s Net-Net 4000 series, span four specific areas, each of which will provide significant benefits to both O1 Communications and its customers:

• 100% increase in media capacity – the higher base capacity content addressable memory (CAM) offered by the Net-Net 4500 enhances access control, supports more subscriber endpoints and provides greater protection against denial of service (DoS) attacks.
• 100% increase in routing capacity – memory twice that of the Net-Net 4250 will support significantly more route entries and ENUM-based services, key enablers for O1’s “Best Voice Path” routing.
• Greater than 100% increase in signaling performance - the Net-Net 4500, offering best-of-breed signaling performance in a carrier-grade 1RU chassis, enables O1 to deliver optimal call quality and assure the service level agreements (SLAs) of its customers through faster and more efficient call admission control (CAC) and QoS marking and reporting. QoS reporting performance is additionally enhanced through optional hardware located on the Network Interface Unit (NIU) of the Net-Net 4500.
• Enhanced hardware-based security acceleration - improved VPN performance is made available to O1’s customers with Net-Net 4500 hardware options that accelerate VPN session establishment and encryption. The Net-Net 4500 Secure Services Module (SSM) provides onboard acceleration for IPsec/IKE and TLS session establishment, while configurable hardware located on the NIU provide dramatically improved encryption performance.

“Our subscriber base expects nothing less than the highest levels of voice service quality even in the presence of increasing call volumes,” said Brad Jenkins, President and CEO for O1 Communications, Inc. “As we expanded our network, the Net-Net 4500 was the easy and logical choice – we doubled our session performance and capacity relative to our installed Net-Net 4250s by simply loading the same configuration file.”

“We are thrilled that Acme Packet has been offered the opportunity to play a continuing role in the expansion of O1 Communications’ network,” said Seamus Hourihan, VP of Marketing and Product Management for Acme Packet. “The Net-Net 4500 is an excellent complement to the Net-Net 4250 systems that O1 Communications has already deployed and will provide them with the flexibility, performance and capacity needed to fuel the continued growth and expansion of their services.”
