The ITU-T has announced (Word) the approval of ITU-T Recommendation J.122 (Second Generation Transmission Systems for Interactive Cable Television Services IP Cable Modems). From the prepublished Recommendation J.122: "As cable operators have widely deployed high-speed data services on cable television systems, the demand for upstream bandwidth has increased, particularly with the popularity of more symmetric data applications. The current Recommendation has been created for the purpose of increasing channel capacity and improving noise immunity. The intended service will allow transparent bidirectional transfer of Internet Protocol (IP) traffic, between the cable system headend and customer locations, over an all-coaxial or hybrid-fibre/coax (HFC) cable network." Cablelabs has issued an associated press release:

  • "The new standard can be used as the foundation upon which IPCablecom IP-communication/telephony services can be offered. The standardization is remarkable due to the fact that work on the specification began less than 18 months ago. The rapid standardization is important to promoting worldwide adoption of this important technology."
