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.

- Cisco C841M-8X (Integrated 8 port GE LAN and 2 port GE WAN)
Table 1-1 describes the pluggable WAN configuration modules available for Cisco 800M Series ISR models.
Table 1-1 Pluggable WAN Modules
The combination of WAN modules supported by the Cisco 800M Series ISR is given as follows:
- Multimode 3G Wireless WAN module in slot 0 and single port serial module in slot 1
- Single port serial module in slot 0 and multimode 3G Wireless WAN module in slot 1
- Single port serial module in slot 0 and single port serial module in slot 1
