ADC and Nuera Communication have struck a deal to offer a cable-based IP telephony system that adheres to PacketCable and IPCablecom specifications.

The agreement is also designed to enable cable operators to leverage their existing switches to offer IP-based voice services in the access network and to create a migration path toward a full-IP system.

Under terms of the deal, ADC will sell and support Nuera's ORCA RDT-8v gateway along with its own DOCSIS 1.1-qualified Cuda 12000 IP Access Switch. To further the effort, the companies have set up a joint laboratory in the U.K. city of Farnborough to test and verify V5.2 systems that leverage the Nuera RDT and ADC's Cuda gear and FastFlow Broadband Provisioning Manager.

The combination, which covers the PacketCable Line Control Signaling spec, will enable cable operators to leverage their V5.2-capable switches for existing EuroDOCSIS-based cable networks, the companies said.

"The work with Nuera provides European and Asian MSOs a cost-effective solution for transitioning the PacketCable while leveraging their existing investments in V5.2 circuit switches," said Hilton Nicholson, president of ADC's IP Cable Business Unit.

The CableLabs PacketCable architecture creates a platform for cable operators to offer a variety of IP-based services and applications, including voice.

IPCablecom, formed in May 2001, serves as a global version of PacketCable, and is backed by organizations such as the Society of Cable Telecommunications Engineers, the European Telecommunications Standards Institute and the International Telecommunication Union.

The first version of IPCablecom specifies how IP telephony services of an operator-owned "single zone" network interfaces to the traditional PSTN (Public Switched Telephone Network).
