Tables 1 and 2 list the routers that currently make up the Cisco 880 data, voice, and SRST series, respectively.
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.
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, http://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
Cisco 880 Series Router performance allows customers to take advantage of broadband network
speeds while running secure, concurrent data, voice, video, and wireless services.
Enhanced security
●
An integrated stateful and application inspection firewall provides network perimeter security.
●
High-speed IPsec 3DES and AES encryption offers data privacy over the Internet.
●
Intrusion prevention enforces security policy in a larger enterprise or service provider network.
●
Content filtering offers category-based URL classification and blocking, thus providing increased
productivity and better use of company resources.
WAN diversity
●
Multiple WAN links include Fast Ethernet, multimode VDSL2/ADSL2/2+, multimode G.SHDSL, 3G, and
ISDN.
Redundant WAN links

switch
●
The Cisco 880 Series allows for connection of multiple devices in a small office, with the ability to
designate a port as the network edge.
●
An optional external PoE adapter powers IP phones and external access points to avoid individual
power supplies or power injectors.
●
VLANs allow for secure segmentation of network resources.
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 highbandwidth 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.
Voice gateway (supported on
881V and 887VA-V voice models)
●
The Cisco 881V and 887VA-V models provide voice gateway functions with the ability to upgrade to a
five-user Cisco Unified Communications Manager Express or five-user SRST).
SRST (supported on SRST voice
models)
●
SRST provides business continuity for voice when the WAN link fails by switching calls to the PSTN.
while maintaining secure and productive voice and data access in their homes. SRST and businesscontinuity 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
