The Arris C4® and C4c™ CMTS eXtended Downstream (XD) Cable Access Module (CAM) supports thirty-two DOCSIS® or twenty-four EuroDOCSIS™ 3.0 downstream channels. These channels are grouped onto four upconverters. With thirty-two DOCSIS Annex B downstream channels, each upconverter supports eight of the channels. With twenty- four EuroDOCSIS Annex A downstream channels, two of the upconverters each support eight of the channels and the other two upconverters each support four of the channels. The Physical Interface Card (PIC) of the XD 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. The downstreamchannels on a single F-connector can span up to 78MHz (Annex B) or 80MHz (Annex A) of spectrum, allowing an MSO flexibility in choosing DOCSIS downstream frequencies.

The XD CAM supports DOCSIS 3.0 downstream channel bonding with variable size bonding groups. This allows for the aggregation of two or more DOCSIS channels to support ultra high bandwidths. For example, Release 7.4 supports up to eight bonded downstream channels. With Annex B channels, eight channel bonding provides a 320Mbps data stream to a subscriber‘s DOCSIS 3.0 cablemodem.

The C4 CMTS contains patented FlexCAM technology that provides fully integrated “hitless” RF sparing. This sparing includes support for multiple XD CAM RF sparing groups, the size of which can vary from one to seven active XD CAMs. If a failure occurs on an XD CAM with “hitless” RF sparing, the spare XD CAM automatically replaces the failed module so that all of the cable modems remain in service with minimal packet loss.
