Cisco IOS Release 12.2(4)XF supports the Cisco uBR10012 universal broadband router, which provides 
a high-capacity, high-throughput cable modem termination system (CMTS), optimized for aggregating 
traffic at the edge of the cable network. Designed for cable operators and service providers, the platform 
connects residential subscribers via cable modems, digital set-top boxes, or IP telephony cable modems 
for high-speed data, broadband entertainment, and IP telephony solutions. 

The Cisco uBR10012 router has been designed as a high-capacity platform that places a new level of 
intelligence at the edge of the network, enabling cable service providers to maximize their revenues by 
delivering more feature-rich services to their customers. The Cisco uBR10012 router uses the 
industry-proven Parallel eXpress Forwarding (PXF) technology, derived from the Cisco ESR10000 Edge 
Services Router, to provide consistent, high-performance throughput, even as software features are 
added and additional services are deployed. 

In addition, it supports a variety of broadband access technologies, including Data-over-Cable Service 
Interface Specification (DOCSIS), gigabit ethernet, and optical. With support for multiple standards, 
operators can choose the appropriate services and devices to optimize their capital investment with a 
single CMTS platform. With access to current and future software enhancements, the Cisco uBR10012 
also ensures investment protection as standards and customer needs continue to evolve. 

Cable companies and Internet service providers (ISPs) can allocate radio frequency (RF) channel 
capacity for Internet access or high priority services using a hybrid fiber/coax (HFC) or an all-coax cable 
plant. Cisco currently provides two router-based DOCSIS CMTS solutions that offer a wider feature set 
and better manageability than bridge-based systems.

The Cisco uBR10012 universal broadband router brings the powerful performance and proven reliability 
of the industry-leading, DOCSIS-qualified Cisco uBR7200 series universal broadband router product 
line to the next level of performance, capacity, and throughput. The Cisco uBR10012 platform provides 
a complete, easy-to-use, integrated router and cable modem termination system (CMTS) package, with 
feature-rich software and unparalleled customer service and support. With access to current and future 
software enhancements, the Cisco uBR10012 routers also ensure investment protection as standards 
evolve.

The Cisco uBR10012 router supports up to eight cable interface line cards for connection to subscriber 
cable modems (CMs) and set-top boxes (STBs). Cisco IOS Release 12.2(4)XF supports the 
Cisco uBR-LCP-MC16C, Cisco uBR-LCP-MC16E, Cisco uBR-LCP-MC28C, and 
Cisco uBR-LCP-MC28C-BNC cable interface line cards. 

For connection to the Internet and other networks, the Cisco uBR10012 router supports up to four 
network uplink line cards, each of which can support connections as fast as 1Gb/s (Gigabit Ethernet). 
Cisco IOS Release 12.2(4)XF supports OC-12 POS and Gigabit Ethernet connectivity.
