Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers Generation 2 Software Configuration Guide
Overview of the Hardware and Software
The Cisco 3900 series, Cisco 2900 series, and Cisco 1900 series integrated services routers (ISRs) offer
secure, wire-speed delivery of concurrent data, voice, and video services. The modular design of these
routers provides maximum flexibility, allowing you to configure your router to meet evolving needs.
The routers offer features such as hardware-based virtual private network (VPN) encryption
acceleration, intrusion-protection and firewall functions, and optional integrated call processing and
voice mail. A wide variety of legacy network modules and interfaces, service modules (SMs), internal
services modules (ISMs), next-generation packet voice/data modules (PVDM3), Services Performance
Engines (SPEs), high-density interfaces for a wide range of connectivity requirements, and sufficient
performance and slot density for future network expansion requirements and advanced applications are
available.
Power-saving hardware and software features are incorporated throughout the series. These routers
provide access to the multi-gigabit fabric, which provides a connection between switch ports without
using up external ports. The logical Gigabit Ethernet (GE) interface on the router connects external and
internal modules through the backplane for LAN and WAN switching. Software feature upgrades are
provided through software licensing.
