Cisco PXF patented technology
Cisco PXF delivers increased performance and flexibility. Using Cisco PXF, the Cisco
uBR10012 helps enable cable operators to turn on multiple services without
experiencing performance degradation—crucial when operators deploy new types of
services. Cisco PXF is a software-based technology that helps enable the Cisco
uBR10012 to implement new services without upgrading hardware, thereby providing
investment protection and saving customers time and money.

Processor redundancy
Processor redundancy helps enable 99.999-percent network uptime, particularly
important when supporting primary line voice services. Each Cisco uBR10012
chassis supports up to 2 Cisco PRE-2 modules for redundancy. Architected to
support 99.999-percent uptime and coupled with a superior set of high-availability
features and functions, the Cisco uBR10012 is the industry’s leading carrier-class
CMTS.
