Cisco 800M Series Integrated Services Routers Overview

This chapter provides an overview of Cisco 800M Series integrated services routers (ISRs), and information about how to configure the features and contains the following sections:

Overview of the Cisco 800M Series ISR

Cisco 800M Series ISRs are entry level branch routers that provide secure network connectivity for small offices to a central location. Cisco 800M Series ISRs are modular routers and provides flexibleWAN connectivity options including Gigabit Ethernet (GE), Serial, and 3G to connect the branch office to central office over a secure tunnel. The Cisco 800M Series ISR can be used for deployment in remote small offices, ATMs and retail stores.
