Cisco IOS Release 12.2(2)XF1 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. Cisco IOS 
Release 12.2(2)XF1 supports the Cisco uBR-LCP-MC28C line card, based on the existing 
Cisco uBR-MC28C line card, with two downstreams and eight upstreams divided into two domains. This 
provides the ability to support a large volume of cable modem subscribers using only one chassis. 

The Cisco uBR10012 router supports both the Cisco uBR-LCP-MC28C line card (which uses 
F-connectors) and the Cisco uBR-LCP-MC28C-BNC (which uses BNC connectors). Unless 
otherwise indicated, all references to the Cisco uBR-LCP-MC28C refer to both versions of the card. 

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(2)XF1 supports OC-12 POS and Gigabit Ethernet connectivity.
