Cisco Cable Wideband Add-on Components
The Cisco uBR10012 router can be used as a DOCSIS 1.x/2.0 CMTS and, in this mode, does not need
any wideband components. Wideband cable components can be added to the Cisco uBR10012 base
system so that it can be used as a wideband CMTS. As demand for wideband cable grows, this ability to
increase capacity by adding wideband components to an existing uBR10012 base system is less
expensive than adding additional chassis. This Cisco Cable Wideband Solution add-on strategy reduces
both capital expenditure and operational expenses.
