DOCSIS 3.0, PacketCable 2.0 components pass ITU study group muster
CableLabs  recently announced that most of the DOCSIS 3.0 specification and key elements of the PacketCable 2.0 specification were given consent status by an International Telecommunications Union  study group.
The consent status by the ITU-T is a stepping stone for both specifications becoming full-blown international standards. The meetings of Study Group 9 took place in mid-June in Singapore and were chaired by CableLabs President and CEO Richard Green. The elements that were agreed upon by SG9 were forwarded to full ITU-T membership for acceptance as ITU Recommendations.
“The June meetings were very important. Once again the world has embraced innovative technologies that were originated by North America’s cable industry with strong support from other countries and made them standards for the world to implement,” Green said, in a prepared statement.
The DOCSIS 3.0 specification establishes ways for cable companies to tie multiple 6 MHz transmission channels together to deliver data at speeds in excess of 160 Mbps to consumers, and at 120 Mbps or more upstream from consumers. The specification also includes support for IPv6, which will open up more IP addresses to cable operators such as Comcast  who will use them on a variety of devices and new IP-based services.
The initial set of IPCablecom2 Recommendations, covering the core elements of the PacketCable 2.0 architecture, was consented by the study group in 2006. The additional standards consented during the Singapore meeting added Home Subscriber Server (HSS) functionality to the architecture. The HSS provides key mechanisms needed to support subscriber mobility and roaming.
