The uBR7246 Universal Broadband Router is two products in one chassis. The Universal Chassis contains the Broadband Subsystem and the Router Subsystem, which are described in detail below.
The Cisco Universal Broadband Router uBR7246 combines the functionality of the industry leading Cisco 7200 router and a head-end cable modem in one integrated platform. The uBR7246provides cable operators with a cost-effective, scalable, and feature-rich interface between subscriber cable modems and the backbone data network. The modular architecture of the uBR7246 maximizes cable operators' investment by enabling them to support multiple network services in one platform and avoid head-end product obsolescence as subscriber modem products and technologies evolve. Cable operators have the ability to deploy a variety of services to customers, including internet access and multimedia applications, while maximizing the efficiency of their network bandwidth utilization, which in turn allows cable operators to derive higher profits from the same scarce network resources.

The uBR Broadband cable subsystem consists of up to 4 modem cards which plug in to the Universal chassis. Each modem card is entirely independent from a radio frequency (RF) standpoint, while all modem cards in the chassis share the Router subsystem. This provides maximum cost-effectiveness and flexibility to the cable operator by amortizing the cost of the routing across all the modems in each chassis, while allowing each of four modem cards to serve a dedicated group of subscriber modems. This flexibility further enables the use of different types of subscriber devices if desired.
Modem Card Types Cisco will ultimately offer a wide variety of modem cards, depending on the types of subscriber modems that are needed. The modem cards Cisco offers are all fully compliant with the MCNS DOCSIS specification.
MC-11: 1 Downstream and 1 Upstream The MC-11 Modem Card contains one 64-QAM downstream modulator and one QPSK upstream demodulator on a single card. The MC-11 modem supports both two-way and telephone-return modems simultaneously. The MC-11 offers cable operators the lowest capital cost for an initial entry point into a market, and is therefore ideal for smaller cable systems or nodal areas with low penetration of cable data service.
MC-14: 1 Downstream and 4 Upstream The MC-11 Modem Card contains one 64-QAM downstream modulator and four QPSK upstream demodulators on a single card. The MC-14 Modem supports both two-way and telephone-return modems simultaneously. The MC-14 provides a very favorable overall cost per subscriber modem, and is well suited for deployment in medium to large cable systems with good penetration of cable data service.
MC-26: 2 Downstream and 6 Upstream The MC-26 Modem Card contains two 64-QAM downstream modulators and six QPSK upstream demodulators on a single card. The MC-26 supports both two-way and telephone-return modems simultaneously. The MC-26 provides the most cost-effective solution on the market on a per-subscriber basis, and is designed to be the workhorse product for medium to large cable systems as their cable data service grows beyond the initial rollout to full-scale market deployment.

The Router subsystem of the uBR7246 is built on the Cisco 7200 platform. The Cisco 7200 provides high-performance, density, and availability with industry-leading serviceability and manageability features. Cable operators can now gain the advantages of high-performance network- layer switching and services, including security, quality of service, and traffic management.
The Cisco uBR7246 series delivers the full suite of Cisco Internetwork Operating System (IOS) software services, which are capable of managing access to network resources, allocating quality of service among applications, and providing value-added functions such as NetFlow switching The Cisco uBR7246 sets new standards in price/performance, meeting requirements for high-throughput at an affordable price.
With a 150-MHz RISC processor and SRAM, the Cisco uBR7246 provides over 600 Mbps of bandwidth capacity and switching performance at 100,000 packets per second (pps). NetFlow switching, Cisco IOS switching mechanism, allows the Cisco uBR7246 to combine high- performance network-layer switching with the connection-oriented-application of network services, such as security, quality of service, and traffic management. It also enables detailed traffic statistics by protocol and IP address.
The Cisco uBR7246 uses the same port adapters as the Cisco 7200 series and the 7500-Versatile Interface Processor (VIP), thus protecting customer investment in interfaces and simplifying sparing.
