SERIES FEATURES OVERVIEW
Cisco 2800 Series
43
* Note: A maximum of 72 IP phones are supported in Cisco IOS
12.3(8)T4 on the Cisco 2851, in Cisco 12.3(11)T a maximum of
96 IP phones will be supported on the Cisco 2851
Integrated Services
With the optional integration of numerous
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 Unity
™
Express
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 maintaining the benefits of integration.
Secure Networking
Integrated on the motherboard of every
Cisco 2800 Series router is hardware-based
encryption acceleration that offloads the
encryption processes to provide greater IPsec
throughput with less overhead for the router
CPU, when compared with software-based
solutions. With the optional integration of VPN
modules (for enhanced performance and tunnel
count), content engine network modules for
URL filtering, or intrusion-prevention network
modules, combined with the rich Cisco IOS
®
Software security feature set that includes
firewall, network access control (NAC), voice
and video-enabled VPN (V3PN), intrusion
prevention, and Dynamic Multipoint VPN
(DMVPN), Cisco offers the industry’s most
robust and adaptable security solution for
branch-office routers.
IP Telephony
The Cisco 2800 Series allows network managers
to provide scalable analog and digital telephony
without investing in a one-time solution, giving
enterprises greater control of their converged
telephony needs. Using voice and fax modules,
the Cisco 2800 Series can be deployed for
applications ranging from voice over IP (VoIP)
and voice over Frame Relay (VoFR) transport
to robust, centralized solutions using the
Cisco Survivable Remote Site Telephony
(SRST) solution or distributed call processing
using Cisco CallManager Express (CCME).
The architecture is highly scalable with the
ability to support up to 12 T1/E1s trunks, 52
foreign-exchange-station (FXS) ports, or 36
foreign-exchange-office (FXO) ports concurrent
with data routing and other services.
