The Cisco® IAD880 Series Integrated Access Devices are cost-effective fixed configuration customer premises equipment for service providers offering managed voice and data services. The Cisco IAD880 Series offers cost-effective platforms for providing interconnect solutions for accelerating the migration from time-division multiplexing (TDM) to voice over IP (VoIP). The Cisco IAD880 Series provides secure concurrent services, including firewall, content filtering, VPNs, and WLANs, at broadband speeds to small offices. The Cisco IAD880 Series includes fixed-configuration platforms with voice ports, WAN uplinks, embedded encryption acceleration, voice digital-signal-processor (DSP) slots on the motherboard, and intrusion-prevention-system (IPS) and IP Security (IPsec) features while maintaining a desktop form factor for space-saving service provider managed services deployments.
Powered by Cisco IOS® Software, the Cisco IAD880 Series supports TDM and VoIP, with proven quality-of-service (QoS) tools, multiple call-control protocols (such as Session Initiation Protocol [SIP], Media Gateway Control Protocol [MGCP], and H.323), and diverse VoIP codecs. The choice of Basic Rate Interface (BRI) voice ports over asymmetric DSL (ADSL) or G.SHDSL furthers the appeal of the Cisco IAD880 Series to service providers for providing managed services.
Primary Features and Benefits to Service Providers
Cost Effectiveness
The Cisco IAD880 Series offers the entire gamut of industry-leading features at a very cost-effective price for service providers. With flexible support for a variety of WAN interfaces and line-side voice interfaces, wireless services, as well as integrated security services, the Cisco IAD880 Series is customized to the unique requirements for the small and medium-sized business. Priced with the small and medium-sized business customer in mind, the feature-rich Cisco IAD880 Series offers superior value to a service provider interested in taking advantage of the growing managed small and medium-sized business services market.
Transparent Service Migration
The Cisco IAD880 Series can help service providers transparently migrate end customers from TDM-based voice service to call agent-based packet voice services without the need for a complete equipment upgrade at the end-customer site. The provider can choose SIP, MGCP or H.323 for VoIP protocols, based on the services that need to be delivered.
Flexibility
The Cisco IAD880 Series offers both TDM and VoIP with rich VoIP signaling protocol support. Combined with the option for call agent- and BRI-based network designs, the Cisco IAD880 Series offers powerful flexibility in the design of next-generation multiservice networks.
