Cisco to Showcase Networking Technology Innovations at National Cable & Telecommunications Association Tradeshow; Cisco CEO John Chambers to Participate on Keynote Panel on Monday, April 10, 2006.

Cisco Systems, Inc. (NASDAQ:CSCO):

WHO: Cisco Systems, Scientific Atlanta, a Cisco company, and Linksys, a division of Cisco Systems

WHAT: NCTA (National Cable & Telecommunications Association) "The 2006 National Show"

WHERE: Atlanta, Georgia, Georgia World Congress Center, April 9-11, 2006

"View from the Top: Leadership Perspectives"

John Chambers, President and CEO, Cisco Systems(R), will participate in a panel discussion on Monday, April 10, 2006, from 9:30 a.m. to 11:00 a.m. (EDT) and discuss the future of the converged communications world and how cable operators can continue to operate at the forefront of new opportunities driven by technology advancement, content proliferation and increasing consumer control of media.

Cisco Demonstrations at Booth No. 3121

Cisco showcases innovative, new IP Next Generation Network (IP NGN) technologies and solutions that allow cable operators to create new services, generate revenue, and reduce capital and operating expenses. Demonstrations include:

IP NGN Service Convergence Layer (Service Exchange Framework)

Demo #1. Differentiated Voice Services: Demonstration shows (a) Caller Identification (ID) on a TV via a set-top box and (b) Session Initiation Protocol (SIP) video telephony services including the Linksys SPA9000 Internet Protocol Private Branch Exchange (IP-PBX) system for business services. An integrated home solution is also demonstrated -- with television (TV) equipped with a Scientific Atlanta Set-Top Box and voice over broadband -- thereby enhancing usability and convenience over a single customer interface.

Demo #2. Fixed Mobile Convergence (FMC): Demonstration shows seamless call handover between a Global System for Mobile Communications (GSM) and a Wireless-Fidelity (Wi-Fi) network using a dual-mode smart phone. The Cisco FMC feature enables broadband customers to use their own dual-mode cell phones to make Voice over IP (VoIP) phone calls over Wi-Fi when at home or at a Wi-Fi "Hotspot," or over a cellular network when out of Wi-Fi network -- increasing Average Revenue per User (ARPU) and reducing capital expenditures (CAPEX).

Demo #3. Cisco Dynamic Flow Control: Demonstration shows how the cable operators can dynamically detect application types and set Quality of Service (QoS). Specifically, customers can be assigned QoS profiles so that they can surf the Web, download content, and stream video without being impacted by peer-to-peer (P2P) traffic -- thus ensuring an enhanced user experience for revenue-generating services and reducing customer churn.

Demo #4. Cisco Content Delivery Network Solution: Demonstration shows two video screens -- one QoS enabled and one not. Cisco's content delivery networking technology signals QoS via PacketCable Multimedia (PCMM), thereby enabling cable operators to offer new IP-based services and long-tail content while simultaneously providing an enhanced, entertainment-grade experience.

Joining Cisco in this demonstration are the following companies and their products:

--Camiant, Inc., a provider of policy control solutions for the delivery of IP-based multimedia applications, and their PCMM policy server; and

--Cauldron Solutions, LLC, a provider of technology solutions that manage the production, distribution and transaction exchange of digital media content across platforms for leading media players, and their Entitlement Platform.

IP NGN Network Convergence Layer

Demo #1. Wideband for Cisco uBR1002 Universal Broadband Router: Demonstration shows a Linksys wideband cable modem receiving multiple downstream radio frequency (RF) channels from a Cisco(R) uBR10012 Universal Broadband Router. Multiple High-Definition TV (HDTV) channels shown on multiple personal computer (PC) screens demonstrate bandwidth far over 38.8 Mbps. Cisco's wideband solution can provide speeds up to about 1 Gbps. Wideband enables MSOs to offer high bandwidth service tiers and as well as new revenue-generating Data Over Cable Service Interface Specification (DOCSIS)-based services.

Demo #2. Internet Protocol Version 6 (IPv6): Demonstration shows a multiple IPv6 enabled applications, including IPv6 PC applications and video to an IPv6 enabled set-top box. Because IPv6 supports a much larger address space than IPv4, it allows MSOs to scale their networks -- a must-have due to rapid growth in both the number of set-top boxes the MSOs must support and the number of IP addressable client devices, such as mobile phones and personal digital assistants (PDAs) that customers want to connect."

Demo #3. IP over DWDM (ONS and CRS-1): Demonstration shows how IP over Dense Wavelength Division Multiplexing (DWDM), implemented on the Cisco CRS-1 and Optical Networking System (ONS) platforms, serve to increase service flexibility while reducing operational expenses (OPEX) and capital expenses (CAPEX) -- through advanced DWDM features that transparently converges the IP/MultiProtocol Label Switching (MPLS) and the DWDM layers to increase efficiencies, increase reliability, and speed service deployments even as traffic growth occurs. The Cisco CRS-1 and ONS platforms also form the backbone of the Cisco booth.

Broadband Access Management and Customer Advocacy

Demo #1. Cisco Broadband Access Management: Demonstration shows the Cisco Broadband Access Center and the Cisco Network Registrar, management products that reduce OPEX and helps enable faster activation of "triple play" services. Products, management and services are all key parts of the Cisco end-to-end solutions.

Demo #2. Customer Advocacy: Demonstration shows a presentation about the various services offered by Cisco. Products, management and services are all key parts of the Cisco end-to-end solution.

Panel Title: "Make Yourself at Home or Digital Domesticity"

The appeal of "anytime/anywhere" service is creating new opportunities as wired and wireless in-home distribution lets subscribers watch, listen to, play and interact with content wherever they choose. Using a variety of portable and personal electronics devices, cable customers are choosing -- and devising -- new ways to tune in, log on and enjoy video and broadband services via home networks and digital gateway options.

This panel examines how the earliest adopters are taking advantage of these tools and services and coping with challenges, such as interoperability and on-screen navigation. Experts also look at what's ahead as the whole home is plugged into the digital cornucopia of entertainment, information and creativity. It's all about the "last 50 feet" as domicile becomes the ultimate digital domain.
