Chapter 4 Cabling the RF Switch With the Cisco uBR10012 CMTS Cable Interface Line Cards
Cisco uBR 3x10 RF Switch with the Cisco uBR10-MC5X20S/U/H Cable Interface
Line Cards
A single Cisco uBR10012 router supports up to eight Cisco uBR10-MC5X20S/U/H cable interface line
cards, each featuring 5 downstream and 20 upstream cable interfaces for a total of 40 downstream and
160 upstream interfaces in the chassis.
For this installation, two Cisco uBR 3x10 RF Switches are required to deploy a redundancy scheme in
which one protect cable interface line card supports from one to seven working cable interface line cards
in the same chassis. See
Note No upconverter is required here as the Cisco uBR10-MC5X20 line cards have built in upconverters.
