Product Overview
This chapter provides an overview of the features available for the Cisco 860 and Cisco 880 series Integrated Services Routers (ISRs), and contains the following sections:
General Description
The Cisco 860 and Cisco 880 series ISRs provide Internet, VPN, voice, data, and backup capability to corporate teleworkers and remote and small offices of fewer than twenty users. These routers are capable of bridging and multiprotocol routing between LAN and WAN ports, and provide advanced features such as antivirus protection. In addition, the Cisco 860W and Cisco 880W series ISRs incorporate an 802.11n wireless LAN option that allows the ISR to act as a wireless access point.
Cisco 860 Series ISRs
The Cisco 860 series ISRs are fixed-configuration data routers, with the router providing a single WAN connection.
•
Cisco 861 and Cisco 861W: Fast Ethernet (FE) WAN connection
The following features are supported:
4-port 10/100 FE LAN Switch
This switch provides four ports of 10/100BASE-T (10/100 Mbps) Fast Ethernet (FE) connection for LANs or access points.
Security Features
The Cisco 860 platforms provide the following security features:
•
•
802.11n Wireless LAN Option
The Cisco 861W ISR has an integrated 802.11n module for wireless LAN connectivity. The router can then act as an access point in the local infrastructure.
Cisco 880 Series ISRs
The Cisco 880 series ISRs are a family of fixed-configuration data and voice routers as described in the following sections:

Common Features
Cisco 880 series ISRs support the following features:
4-port 10/100 FE LAN Switch
This switch provides four ports of 10/100BASE-T FE connection for LANs, access points, or IP phones. In addition, an upgrade is available that gives Power over Ethernet (PoE) on two of the ports to provide power to access points or phones.
802.11n Wireless LAN Option
The Cisco 880W series ISRs have an integrated 802.11n module for wireless LAN connectivity. The router can then act as an access point in the local infrastructure.
Real Time Clock
A real-time clock (RTC) provides date and time when the system is powered on. The RTC is used to verify the validity of the Certification Authority stored on the router.

Licensing
Cisco 860 and Cisco 880 ISRs ship with licensed software installed. Software features may be upgraded and the software licenses managed through Cisco Licensing Manager. See the Cisco Software Activation Conceptual Overview on Cisco.com for details.
When you order a new router, you specify the software image and feature set that you want. They are installed on your router before you receive it, so you do not need to purchase a software license. The router stores the software license file on the flash memory.
Selecting Feature Sets
Feature sets are bundled and offered as a software license installed on hardware platforms. See the <Marketing Datasheet> for a list of features available with the software license on the Cisco 860 and Cisco 880 platforms. See the Cisco Software Activation Conceptual Overview on Cisco.com for details about how to activate and manage the software licenses.
