DETAILED DESCRIPTION OF PROBLEM:
Cable operators are actively engaged in upgrades to extend the frequency range of the upstream plant to 85 MHz.
DOCSIS 3.0 specification text permits this frequency extension, but ONLY if the cable modem incorporates a
physical layer switched output bandwidth to support operation in plants with either legacy or extended upstream
frequency plans. There is no allowance for certification of a cable modem that supports only the extended
frequency plan, thus forcing cable operators to incur significant extra costs associated with switchable bandwidth
upstream operation. In anticipation of the fact that operators will eventually complete upstream frequency
extension, this EC allows for certification of cable modems that are compliant with the extended frequency
operation only, thus reducing the cost of equipment for those operators who do not require dynamic upstream
bandwidth selection.
