CHICAGO -- CopperCom and Calixannounced today that they have agreed to work on the implementation, interoperability anddelivery of H.248 access and switching solutions to meet the unique needs of wireline serviceproviders deploying next-generation communications services. The companies will work closelyon the interoperability of H.248 broadband service signaling on their respective products toensure seamless interworking for customers deploying next-generation networks.

Calix and CopperCom are a natural fit, with Calix leading in ultra-broadband fiber and copperaccesssolutions and CopperCom leading in next-generation soft switching solutions. Bothcompanies share a common customer set and vision—delivering the highest value switch-basedservices over the most advanced broadband infrastructure.H.248 is a standard protocol supported by the International Telecommunications Union (ITU) thatprovides the signaling and session management for voice over Internet Protocol (VoIP) services.

By cooperating on the interoperability of H.248 solutions on their respective platforms, Calix andCopperCom ensure that customers deploying either platform have a seamless path to the futurefor broadband services.

“Working with CopperCom is a natural step for us,” said Rick Johnston, vice president of businessdevelopment at Calix. “We have many common customers, and we are both dedicated to servingour market with the highest level of service and reliability that our customers demand. TheCopperCom platform is widely deployed among wireline service providers, and we look forward todefining the future with them.”

“We are extremely pleased to be working with Calix,” said Bob Kersey, vice president, productmanagement at CopperCom. “We have already worked with Calix and the C7 platform on legacyinterfaces. Making the move concurrently to H.248 gives our customers the confidence that theycan deploy a broadband services infrastructure with the knowledge that the access and switchingparts of that network are ready to deploy value-added services”.CopperCom and Calix work with each other’s equipment in their respective labs, and havealigned their product and development roadmaps to deliver H.248 to their customer base.

In a separate release:

CHICAGO -- Calix and MetaSwitch announced today that, under the auspices of theCalixCompatible and MetaSwitch Interoperability Partner programs, the two companies are workingclosely to speed the transformation of carrier networks to voice over IP (VOIP). As traditionalwireline carriers of all sizes face intensified competition from cable operators, migrating traditionalcircuit-based voice services to an open packet-based softswitch architecture can substantiallyreduce operating expenses and enhance flexibility. Employing softswitches from MetaSwitch andultra-broadband fiber- or copper-based access infrastructure from Calix enables service providers toquickly and easily migrate to pure IP networks—while maintaining traditional network-powered PlainOld Telephone Services (POTS) to end users.

Yelcot Telephone, based in Mountain Home, Arkansas, is one of a growing number of serviceproviders that are moving to a softswitch-based service delivery architecture. “Having selected Calixand MetaSwitch as the best-of-breed suppliers, we welcome the fact that they are working closelytogether on next generation standards and capabilities that will allow us to compete in a fastchangingtelecom environment,” said Dave Marberry, Asst. Plant VP at Yelcot Telephone. “Ourinitial cut-over of 4,000 lines is just the start: we are really excited by the potential for new revenuegeneratingservices and reduced management costs that the joint Calix-MetaSwitch solutionenables.”

The Calix C7, a 200 Gbps multiservice access platform (MSAP), employs a pure-packet fabric,thereby making the transformation to H.248-based voice signaling a logical extension. Working withsoftswitch providers like MetaSwitch, Calix ILEC customers are able to transition their TDM accessnetwork and voice switching infrastructure to VOIP through the simple addition of a VOIP gatewayprocessor in existing systems.

According to Frank Wiener, Calix vice president of field marketing, “our customers have beenresoundingly clear: along with the deployment of new revenue generating services, they know theywill need to migrate their networks to IP so they can reduce the costs of delivering legacy services.Providing interoperability with leading telephony switch suppliers such as MetaSwitch facilitates asimple migration to VOIP with H.248 for service providers, giving them a clear path to IP.”

The MetaSwitch product line includes a range of options for carriers to deploy packet and/or TDMbasedservices either as a replacement for, or alongside, existing Class 5 and Class 4 switches. Anopen distributed softswitch architecture, including call agent, application server, media gateway andsignaling gateway components, ensures network flexibility and scalability. MetaSwitch exclusivelyemploys industry standard protocols such as SIP and H.248 for maximum interoperability with arange of next generation devices including IP-based access equipment such as the Calix C7.

“The majority of our 120+ deployments include the delivery of Class 5 services over a packetaccess infrastructure,” noted Chris Mairs, MetaSwitch senior vice president of product managementand business development. “We therefore know from extensive field experience that simply claimingsupport for a particular standard, or performing basic functional testing, does not guarantee that asolution will work in the real world. That is why engineering-led initiatives such as the MetaSwitchInteroperability Partner Program, and Calix’s CalixCompatible program, are so important to ourcustomers’ successful migration to softswitch-based networks.”
