Chapter 3 Cisco Cable Wideband Architecture

Wideband Cable Modem Functionality

A wideband channel uses the same DOCSIS frame format as a traditional DOCSIS channel uses. The

channel just has more bandwidth. A new extended header for wideband has been added to the DOCSIS

protocol. The extended header defines the logical wideband channel and a sequence number that the

wideband cable modem uses for re-sequencing the wideband packets.

The CISCO-CABLE-WIDEBAND-MODEM-MIB for the wideband cable modem is supported and is an

extension to the existing cable modem MIB.
