Product Overview
This chapter provides an overview of the features available for the Cisco 860 series, Cisco 880 series, 
and Cisco
 890 series Integrated Services Routers (ISRs), and contains the following sections:
 General Description, page 1-1
 Cisco 860 Series ISRs, page 1-2
 Cisco 880 Series ISRs, page 1-3
 Cisco 890 Series ISRs, page 1-11
 Hardware Features, page 1-13
NoteFor compliance and safety information, see Regulatory Compliance and Safety Information Roadmap 
that ships with the router and 
Regulatory Compliance and Safety Information for Cisco 800 Series and 
SOHO Series Routers.
NoteThe illustrations in this document show a wireless router. Both wireless and nonwireless models are 
available in the Cisco
 860 series, Cisco 880 series, and Cisco 890 series ISRs. Port and feature locations 
are similar for both wireless and nonwireless routers.
General Description
The Cisco 860 series, Cisco 880 series, and Cisco 890 series ISRs provide data, voice, Wi-Fi 
CERTIFIED™ wireless access point (AP), integrated Virtual Private Network (VPN), and backup 
capabilities to corporate teleworkers and to remote and small offices with fewer than 20 users. These 
routers are capable of bridging and multiprotocol routing between LAN and WAN ports. The routers 
provide advanced features such as global industry standard symmetrical high-speed DSL (G.SHDSL), 
very-high-data-rate digital subscriber line 2–over–plain old telephone service (VDSL2oPOTS), 802.11n, 
quality of service (QoS), firewall, antivirus protection, and Secure Socket Layer (SSL).
The Cisco 860 series, Cisco 880 series, and Cisco 890 series ISRs have a desktop form factor with 
built-in wall-mount features. The Cisco 890 series ISRs also have optional rack-mount features. These 
ISRs are powered by an external power supply adapter. The various models differ in the WAN interface 
and features that they support.
