SECURE NETWORK CONNECTIVITY FOR DATA, VOICE, AND VIDEO
Security has become a fundamental building block of any network. Routers play an important role in any network defense strategy because
security needs to be embedded throughout the network. The Cisco 2800 Series features advanced, integrated, end-to-end security for the
®
delivery of converged services and applications. With the Cisco IOS
Software Advanced Security feature set, the Cisco 2800 provides
a robust array of common security features such as a Cisco IOS Software Firewall, intrusion prevention, IPsec VPN, Secure Shell (SSH)
Protocol Version 2.0, and Simple Network Management Protocol (SNMPv3) in one secure solution set. Additionally, by integrating security
functions directly into the router itself, Cisco can provide unique intelligent security solutions other security devices cannot, such as network
admissions control (NAC) for antivirus defense; Voice and Video Enabled VPN (V3PN) for quality-of-service (QoS) enforcement when
combining voice, video, and VPN; and Dynamic Multipoint VPN (DMVPN) and Easy VPN for enabling more scalable and manageable VPN
networks. In addition, Cisco offers a range of security acceleration hardware such as the intrusion-prevention network modules and advanced
integration modules (AIM) for encryption, making the Cisco 2800 Series the industry's most robust and adaptable security solution available for
branch offices. As Figure 2 demonstrates, using a Cisco 2800 Series uniquely enables customers to deliver concurrent, mission-critical data,
voice, and video applications with integrated, end-to-end security at wire-speed performance.
CONVERGED IP COMMUNICATIONS
As shown in Figure 2, the Cisco 2800 Series can meet the IP Communications needs of small-to-medium sized business and enterprise branch
offices while concurrently delivering an industry-leading level of security within a single routing platform. Cisco CallManager Express (CME)
is an optional solution embedded in Cisco IOS Software that provides call processing for Cisco IP phones. This solution is for customers with
data-connectivity requirements interested in deploying a converged IP telephony solution for up to 72 IP phones and—as of Cisco IOS 12.3(11)
release—for up to 96 IP phones. With the Cisco 2800 Series, customers can securely deploy data, voice, and IP telephony on a single platform
for their small-to–medium sized branch offices, helping them to streamline their operations and lower their network costs. The Cisco 2800
Series with optional Cisco CME support offers a core set of phone features that customers require for their everyday business needs and takes
advantage of the wide array of voice capabilities that are embedded in the Cisco 2800 Series (as shown in Table 1) together with optional
features available in Cisco IOS Software to provide a robust IP telephony offering for the small to medium-sized branch-office environment.
INTEGRATED SERVICES
Figure 2 also highlights the fact that with the unique integrated services architecture of the Cisco 2800 Series, customers can now securely
deploy IP Communications with traditional IP routing while leaving interface and module slots available for additional advanced services.
With the optional integration of a wide array of services modules, the Cisco 2800 Series offers the ability to easily integrate the functions of
standalone network appliances and components into the Cisco 2800 Series chassis itself. Many of these modules, such as the Cisco Network
Analysis Module, Cisco Voice Mail Module, Cisco Intrusion Detection Module, and Cisco Content Engine Module, have embedded processors
and hard drives that allow them to run largely independently of the router while allowing management from a single management interface. This
flexibility greatly expands the potential applications of the Cisco 2800 Series beyond traditional routing while still maintaining the benefits of
integration. These benefits include ease of management, lower solution costs (CAPEX and OPEX), and increased speed of deployment.
