The Cisco 880 Series is ideal for small branch offices and teleworkers who need to be connected to larger enterprise networks as well as small businesses for either voice or data applications. These routers help extend corporate networks to secure remote sites while giving users access to the same applications found in a corporate office. When users require WLAN access, visibility and control of network security are even more critical at the remote site. The Cisco 880 Series meets this need with a single device that combines integrated 802.11g/n capabilities with security features such as Wi-Fi Protected Access (WPA), including authentication with IEEE 802.1x with Cisco Extensible Authentication Protocol (LEAP) and Protected EAP (PEAP) and encryption with WPA Temporal Key Integrity Protocol (TKIP). (Refer to the wireless solution overview and security data sheet for more information.) The Cisco 880 Series models that include the integrated access point can use either autonomous or Cisco Unified WLAN modes. In Cisco Unified WLAN mode, as part of an enterprise WLAN architecture, all WLAN functions are centrally managed through Cisco Wireless LAN Controllers and the Cisco Wireless Control System (WCS).
Service providers and value-added resellers can take advantage of the Cisco 880 Series to provide a true business-class broadband service. Business customers are using broadband access to connect to the Internet or to connect offices together, and they require a platform that incorporates voice and security without sacrificing performance. The Cisco 881V and Cisco 887VA-V voice routers offer industry-leading voice gateway capability with the ability enable Cisco Unified Communications Manager Express or SRST as required. Many of these customers are connecting computers in offices through WLANs; having a single device for both WAN and WLAN access provides a new option for managed services. These customers also require a higher level of support to keep their networks operational. Services with these customers should be simple to set up, while allowing a level of remote management and troubleshooting to address support inquiries quickly. The Cisco 880 Series meets the requirements of small offices and managed services providers.

Figure 2 shows deployment scenarios.

Figure 2. Deployment Scenarios

Applications
The Cisco 880 Series is ideally suited for deployment in a small office or in a small office that is part of a large network, most often with a secure VPN connection. These types of offices can include the following:
●   Small remote office: The Cisco 880 Series can connect users in a small remote office, such as an insurance, lawyer, or sales office. When connecting to the main office, VPN encryption and integrated security such as firewall and intrusion prevention protect the network at the perimeter. The Cisco 880 with the Cisco Unified Border Element Series can also support connection to SIP trunking Voice-over-IP (VoIP) services the service provider offers. Additionally, IT managers can centrally manage the remote site to quickly troubleshoot any network problems. For added reliability, customers can also use the integrated 3G or ISDN backup or connect through an external modem if the primary broadband link fails. Integrated secure unified WLAN connectivity simplifies the deployment and management devices at the remote site. Redundant WAN links offer business continuity, enabling nondisruptive business operation.
●   Virtual office: The Cisco 880 Series is ideal for corporate teleworkers who have a mix of broadband connection types such as DSL, 3G, and Metro Ethernet. The Cisco 880 Voice Gateway and SRST Series provides a secure virtual office with all the collaborative services such as data, voice, and fax services. SRST helps ensure voice services are operational in case of WAN link failure, and redundant WAN links help ensure business continuity. QoS features in the Cisco 880 Series allow for connection of an IP or analog phone to the router, giving voice traffic precedence over data applications. Integrated WLAN support in the Cisco 880 Series helps ensure that if wireless connectivity is used it is secure. (Refer to the Cisco Virtual Office Solution, https://www.cisco.com/go/cvo, for more information.)
●   Remote call-center agent: Similar to teleworking applications, this solution extends the Cisco IP Contact Center solution for telephone call-center agents to remote sites. With a high-quality, secure connection through the Cisco 880 Series, call-center agents can be dispersed away from costly call-center facilities while maintaining secure and productive voice and data access in their homes. SRST and business-continuity solutions in the Cisco 880 Series provide reliability and continuous business operation. Alternatively, the remote call-center agent can be provided with SIP trunking service with service demarcation provided by Cisco Unified Border Element features, and the central call center can forward calls to the remote call-center agent through the remote-office SIP trunk.
●   Retail VPN: Retail stores migrating from dialup connections for point-of-sale transactions can use the Cisco 880 Series to take advantage of low-cost broadband access with the required security to comply with Payment-Card-Industry (PCI) and other data security requirements. They can then add multiple devices and applications to the store network to take advantage of the increased bandwidth and also incorporate optional WLAN support to enable secure mobility and enhance productivity.
●   Managed services: Service providers and value-added resellers can use the Cisco 880 Series as a platform to offer differentiated business-class security, voice, and WLAN services for small business customers. With built-in analog and digital voice ports and the ability to upgrade to a five-user Cisco Unified Communications Manager Express IP PBX, service providers can now offer all the Cisco Unified Communications benefits to small and medium-sized businesses. The SIP trunking connectivity features of the Cisco 880 with the Cisco Unified Border Element Series Router can provide the high-quality VoIP service needed through the service provider cloud.

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.
