Cisco Broadband Innovations Fact Sheet

The Internet is moving from dial-up modems and slow connections to a world of high-speed broadband using a variety of technologies. High-speed broadband access to the Internet and corporate networks has become a necessity for users in today's networked world. Broadband access directly improves employee productivity and provides a foundation for rich new voice and video services. Already, many corporations and educational institutions have instituted broadband solutions.

Cisco is developing a full range of broadband innovations-cable and digital subscriber line (DSL) products for home and remote office access, Ethernet for wired in-building access, and high-speed wireless access solutions. Cisco engineers have developed many broadband innovations:

Cable

Cisco uBR7200 Universal Broadband Router
In 1998, Cisco delivered the industry's first router CMTS (Cable Modem Termination System) based on the Data-Over-Cable System Interface Specification (DOCSIS). This router, the uBR7200 Universal Broadband Router, incorporates everything a cable operator needs to run data services over cable and permanently changed the way cable operators could scale and deploy Internet Protocol (IP) services.

Ethernet

Long Reach Ethernet
Cisco engineers created the Cisco Long-Reach Ethernet broadband networking solution-the industry's first end-to-end product line for delivering 5 to 15 megabit-per-second performance over existing Category 1/2/3 wiring. With Ethernet-like performance that reaches up to 5,000 feet, Long-Reach Ethernet enables simultaneous voice, video, and data applications without the need to rewire.

Cisco Catalyst 6500 10 Gigabit Ethernet Modules
Cisco engineers developed a high-density Gigabit Ethernet-over-copper module for the Cisco Catalyst 4000 family of switches. This module enables customers to deploy Gigabit Ethernet over copper to the desktop through every port.

Software

Cisco IOS Software
Cisco's IOS Software is a feature-rich, network system software which runs all of Cisco's routers, switches and other gear. With Cisco IOS Software running on the wireless infrastructure, customers deploying the new Aironet 1100 Series Access Point are able to extend intelligent network services, including Virtual Local Area Networks (VLANs), Quality of Service (QoS) and Proxy Mobile IP to the wireless.

Wireless

Wireless LANs
Cisco engineers developed wireless distributed data networks (rather than star-configured radio systems). With these networks, an end point can roam throughout an area without losing connectivity-much like a cellular telephone user can roam about, but with more stringent guarantees for data integrity. The team has nearly 30 patents in areas related to wireless networking, including roaming, spread-spectrum technology, and application specific integrated circuit (ASIC) design. They also took leading roles in the definition of wireless local-area network standards, known as IEEE 802.11.
