Chapter 4 Cabling the RF Switch With the Cisco uBR10012 CMTS Cable Interface Line Cards
Protection Scheme for the Cisco uBR10012 CMTS
Cisco uBR 3x10 RF Switch with the Cisco uBR-LCP2-MC16x (C, E, S) or MC28C
Cable Interface Line Cards
A single Cisco uBR10012 router supports:
• Up to eight Cisco uBR10-LCP2-MC16C, E, or S cable interface line cards, each featuring one
downstream and six upstream cable interfaces for a total of 8 downstream and 48 upstream interfaces
in the chassis.
• Up to eight Cisco uBR10-LCP2-MC28C cable interface line cards, each featuring up to two
downstream and eight upstream cable interfaces for a total of 16 downstream and 64 upstream
interfaces in the chassis.
A single Cisco uBR 3x10 RF Switch is connected to the Cisco uBR10012 router, allowing you to employ
a redundancy scheme in which one protect cable interface line card supports from one to seven working
line cards in the same chassis. Keep in mind that like cards back up like cards (for example, a
Cisco uBR10-LCP2-MC28C line card is required to back up Cisco uBR10-LCP2-MC28C line cards).
Note An upconverter is required with this configuration.
