CON/AUX port 
● 
A single dual-purpose port provides direct connection to a console or external modem 
for management or backup access points. 
Optional 802.11g/n access point 
● 
This broadband router offers a secure integrated access point in a single device. 
● 
This integrated Wi-Fi access point offers IEEE 802.11n 2.0 standard support for mobile 
access to high-bandwidth data, voice, and video applications through the use of multiple-
input, multiple-output (MIMO) technology that provides increased throughput, reliability, 
and predictability. 
● 
The Cisco 880 Series supports both autonomous and unified modes. 
Real-time clock 
● 
A built-in real-time clock maintains an accurate date and time for applications that 
require an accurate time stamp, such as logging and digital certificates. 
SRST (supported on SRST voice models) 
● 
SRST provides business continuity for voice when the WAN link fails by switching calls 
to the PSTN. 
CUBE (supported on CUBE voice models) 
● 
Support for SIP trunk connectivity, including demarcation and interworking, based on 
Cisco Unified Border Element feature license. 
● 
Transcoding of Media is NOT supported on the Cisco 880 Series CUB E feature set. 
Cisco Configuration Professional

Cisco Configuration Professional uses smart wizards and task-based tutorials, which 
resellers and customers can use to quickly and easily deploy, configure, and monitor a 
Cisco access router without requiring knowledge of the Cisco IOS Software command-
line interface (CLI). 
Unified wireless management 
● 
Configuration and management of access points is automated and simplified without 
manual intervention. 
● 
A unified hybrid remote-edge access point (HREAP) provides the following: 
◦
  WLAN services to remote and branch offices without deploying a wireless LAN 
controller at each location 
◦
  Central configuration and control of unified WLAN services for remote offices through 
a WAN link 
◦
  Flexibility in setting up wireless access at remote locations by specifying how traffic is 
to be bridged or tunneled 
Summary 
Cisco 880 Series Integrated Services Routers combine increased network performance with advanced security to 
allow small-office customers to get the most from their broadband connections for both data and voice 
applications. With models supporting different broadband technologies such as DSL, 3G, and Metro Ethernet, the 
Cisco 880 Series can be deployed at any small-office location. Optional integrated 802.11g/n wireless capabilities 
provide true business-class WAN and WLAN access in a single solution. With the Cisco 880 Series, enterprise IT 
managers and service providers can take advantage of a solution that can be easily set up at the remote site and 
can be centrally managed to reduce ongoing operational costs.
