During a CableLabs-hosted two-week IPv6 interoperability event Sept. 19-30, two separate calls involving IPv6 interoperability were completed:



  • A PacketCable 2.0 SIP call between a PacketCable 2.0 embedded digital voice adapter (EDVA) and session border controller (SBC) over IPv6


  • A PacketCable 2.0 SIP call between an IPv6 E-DVA and IPv4 EMTA




The event was the seventh in a series of IPv6 interoperability events hosted by CableLabs. The successful tests signal the ability of cable technology to support calling across both IPv4 and IPv6.

Representatives from 16 companies worked together to test IPv6 interoperability in a range of products including DOCSIS 3.0 cable modems, DOCSIS 2.0+IPv6 cable modems, CMTSs, PacketCable EDVAs, e-set-top boxes, provisioning servers, home gateways, consumer electronics devices, and carrier-grade NAT servers.

Companies that participated in the interop included A10 Networks, Alcatel Lucent, ARRIS, Broadcom, Casa Systems, Cisco, Ericsson, GENBAND, Huawei, Incognito Software, Intel, Juniper Networks, LG Electronics, Motorola, Netgear, and ST Microelectronics.

Participants also tested DOCSIS and PacketCable IPv6 provisioning, Internet video streaming, eRouter and standalone home router configuration, and interoperability with consumer electronics equipment and PCs running Windows XP, Windows 7, Mac OS X, and Linux. In addition, suppliers tested NAT444 and Dual-Stack Lite.
