Models of the Cisco 880 Series ISRs
Product Overview
This chapter provides an overview of the features available for the Cisco 860, Cisco 880, and Cisco 890 series Integrated Services Routers (ISRs), and contains the following sections:
General Description
The Cisco 860, Cisco 880, and Cisco 890 series ISRs provide Internet, VPN, voice, data, and backup capability to corporate teleworkers and remote and small offices of fewer than 20 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, Cisco 880W, and Cisco 890W 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 three models of the router available, each providing a single WAN connection:
•
Cisco 861 and Cisco 861W: Fast Ethernet (FE) WAN connection
The following features are supported by all three models:
4-port 10/100 FE LAN Switch
This switch provides four ports for connecting to 10/100BASE-T (10/100 Mbps) Fast Ethernet (FE) 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 802.11b/g/n single radio module for wireless LAN connectivity. With this module, 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:
•
Models of the Cisco 880 Series ISRs
The family is divided into groups that provide different WAN connections:
•
•
•
The Cisco 881 and 888 groups contains the following models:
•
•
–
–
•
•
The Cisco 887 group consists of the basic data router only.
Each router has one WAN port. In addition, the voice routers have either FXS or BRI voice ports. Data or voice backup ports are also available on most of the routers. The Cisco 880G routers come with a commercial third-generation (3G) wireless interface card that provides cellular backup.
Table 1-1 gives the port configurations of the Cisco 880 series data routers.
Table 1-2 gives the port configurations of the Cisco 880 series voice routers.

Common Features
Cisco 880 series ISRs support the following features:
4-port 10/100 FE LAN Switch
This switch provides four ports for connecting to 10/100BASE-T FE 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 802.11b/g/n single radio module for wireless LAN connectivity. With this module, the router can 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
CiscThe 860, Cisco 880, and Cisco 890 ISRs ship with licensed software installed. Software features may be upgraded and the software licenses may be managed through Cisco Licensing Manager. See Software Activation On Cisco Integrated Services Routers on Cisco.com for details.
When you order a new router, you specify the software image and feature set that you want. The image and feature set 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
Some feature sets are bundled and offered with a software license that is installed on the hardware platforms. For a list of features available with a software license on the Cisco 860, Cisco 880, and Cisco 890 platforms, see the Cisco 860 Data Sheet, the Cisco 880 Data Sheet, and the Cisco 890Data Sheet. See Cisco IOS Software Activation Tasks and Commands on Cisco.com for details about how to activate and manage the software licenses.
