Acme Packet Introduces New Capabilities for Cable and DSL Service Providers Delivering IP-Based Broadband Interactive Communications.Business/Technology Editors WOBURN, Mass.--(BUSINESS WIRE)--May 14, 2002 Adds MGCP See MGCP/MEGACO. MGCP - Media Gateway Control Protocol support and enhances session admission control for broadband access See broadband and wireless broadband. networks Acme Packet(TM) today announced new capabilities in its Net-Net(TM) family of Session Aware Networking(TM) products to support cable and DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary providers delivering high-quality interactive voice, video and multimedia communications. Enhancements to the Net-Net family include MGCP proxy/NAT support and a robust session admission control feature. These new capabilities, together with previously introduced features, enable service providers to satisfy critical address preservation, security, SLA (1) (StereoLithography Apparatus) See 3D printing. (2) (Service Level Agreement) A contract between the provider and the user that specifies the level of service expected during its term. assurance, revenue and profit protection, and law enforcement requirements for interactive communications over broadband networks. With this announcement, all of Acme Packet's previously introduced capabilities for SIP networks are now available for MGCP. The ability to simultaneously support both protocols enables coexistence and the gradual migration from MGCP to SIP. The patents-pending Net-Net products now also satisfy both PacketCable 1.1 and 1.2 signaling protocol requirements. Acme Packet's enhanced session admission control feature complements DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. aggregation and CMTS (Cable Modem Termination System) A computerized device that enables cable modems to send and receive packets over the Internet. It inserts IP packets from the Internet into MPEG frames and transmits them to the cable modems via an RF signal. equipment to ensure premium, high-quality service, including instant voice and video calling using SIP-based softphones on Windows XP PCs. All voice and video traffic using the provider's call signaling infrastructure can be guaranteed priority delivery over any other traffic. Policies can be established that limit the number and type (e.g. voice vs. video) of simultaneous calls from or to any individual business or residence, or logical or physical segment of the access network. Additionally, call set-up requests will not be accepted if there is any congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. within the required segments of the access network so that call quality for currently active calls remains high. "To realize the successful deployment of IP-based interactive communications over broadband networks, cable and DSL providers must guarantee a high-quality experience to their money paying business and residential customers," said Andy Ory, president and CEO (1) (Chief Executive Officer) The highest individual in command of an organization.

"With Acme Packet Net-Net, service providers using SIP or MGCP can satisfy not only their SLA requirements but very important security, revenue protection and law enforcement requirements as well when delivering voice, video or multimedia communications." Net-Net Solutions for Broadband Access Networks - Cable & DSL At cable and DSL access network aggregation points, Acme Packet Net-Net performs critical security, SLA assurance, revenue and profit protection and law enforcement functions: Security - To protect internal network resources, such as softswitches, SIP servers, gateways, and application servers, from DoS attack, Net-Net explicitly authorizes incoming sessions and hides all internal network topology information in both signaling messages and media flows. SLA assurance - Acme Packet Net-Net performs session admission control based upon the available bandwidth on shared access network segments connecting multiple subscribers to the core network. If no bandwidth is available, the call will be rejected because acceptance would deteriorate the quality of all active calls. Net-Net further assures SLA performance and optimal traffic management within the core network by explicitly assigning required QoS markings at both Layer 2 and 3 for signaling messages and media flows. Reporting capabilities include per-flow, end-to-end QoS measurements for SLA reporting, problem alerting and problem isolation. The source of poor quality can be isolated to the source network, core network, or destination network. Revenue and profit protection - A bandwidth policing feature protects revenue and profits by preventing a low bandwidth voice call from turning into a high bandwidth video call without explicit authorization. Comprehensive per session accounting records are produced for tracking or billing purposes. Law enforcement - Acme Packet Net-Net satisfies law enforcement requirements, such as CALEA CALEA Commission on Accreditation for Law Enforcement Agencies, Inc. (Fairfax, Virginia) CALEA Communications Assistance for Law Enforcement Act of 1994 CALEA Communication Assistance to Low Enforcement Act , by supporting transparent session replication and routing of signaling messages and media flows to law enforcement agencies A law enforcement agency (LEA) is a term used to describe any agency which enforces the law. This may be a local or state police, federal agencies such as the Federal Bureau of Investigation (FBI) or the Drug Enforcement Administration (DEA). . Net-Net Solutions for SIP-Based Core Networks In addition to performing these critical functions at access network aggregation points for SIP or MGCP communications, Acme Packet Net-Net performs several other important roles within core SIP networks. Interactive communications services such as unified messaging, conferencing, and others, require multiple SIP application servers to satisfy redundancy and capacity requirements. Similarly, PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. connectivity requires multiple distributed gateways. Acme Packet Net-Net assures SLA performance by distributing calls to the least-loaded available server or gateway, protecting against failure and overload, and routes sessions to the appropriate gateway, minimizing PTSN PTSN Public Telephone Switched Network termination charges. Extending the reach and value of their IP network demands that broadband operators establish business and network relationships with other service providers for IP-based session transit and termination, and PSTN origination and termination. Acme Packet Net-Net performs security, SLA assurance, and revenue and profit protection functions required for connecting these IP networks to the core network. Availability - Acme Packet Net-Net is currently in beta testing (programming) beta testing - Testing a pre-release (potentially unreliable) version of a piece of software by making it available to selected users. This term derives from early 1960s terminology for product cycle checkpoints, first used at IBM but later standard throughout the with general availability (GA) scheduled for Q3.
