XD CAM Field Software Upgrade
Overview
The C4/C4c CMTSs support an upgraded version of the 16D CAM. It is known as the eXtended Downstream (XD) CAM, and
supports 32 downstreams when configured for Annex A or Annex B. Customers can upgrade existing DOCSIS 3.0 16D CAMs
to XD CAMs in order to support these higher densities. The high density XD CAM allows operators to deploy more
downstream channels per service group and per C4/C4c CMTS.
