User Roles Required to Work with Cable Technologies
• Wideband Channels—A Wideband Channel or Bonded Group (BG) is a logical grouping of one or
more physical RF channels over which MPEG-TS packets are carried. Wideband channel carries
DOCSIS bonded packets encapsulated in MPEG-TS packets from a WCMTS to one or more WCMs.
The wideband channel, comprising of one or more RF channels on the EQAM device, is used for
DS data traffic. The US channels on the Cisco uBR-MC3GX60V or Cisco uBR10-MC5X20 cable
interface line cards are used for US traffic.
• Fiber Node—A Fiber Node allows the Multiple Server Operator (MSO) or service provider to
configure the CMTS to be more intelligent by making Cisco IOS aware of how the cable plant is
wired. The downstream channels of the cable plant must be accurately configured in the CMTS fiber
nodes. This allows the CMTS to accurately signal the wideband modems on which the wideband
channels are available to the modem.
