ARRIS 32D CAM

The ARRIS C4 eXtended Downstream (XD) Cable Access Module (CAM) supports 32 DOCSIS 3.0 downstream channels. These channels are grouped onto four upconverters. With 32 DOCSIS Annex B downstream channels, each upconverter supports 8 of the channels.
The Physical Interface Card (PIC) of the 32D CAM is the same as for the 16D CAM and has four F-connectors with each F-connector connected to the output of one of the upconverters. Each downstream channel on the same upconverter / F-connector must have a unique center frequency, but the channels are not required to be contiguous.
