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, advanced application inspection and control,
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, including wired and cordless WLAN
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)T 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.
WIRELESS SERVICES
The Cisco 2800 Series can provide a complete wireless solution for branch offices, small/medium sized businesses, and Wi-Fi hotspots. Wireless
services enable greater mobility for employees, partners, and customers, resulting in increased productivity. The Cisco 2800 Series supports an
integrated access point for wireless LAN connectivity, Wi-Fi Hotspot services for public access, wireless infrastructure services for cordless
WLAN telephony and for larger sites, and land mobile radio over IP for radio users.
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.
