The Cisco IAD 880 Series Integrated Access Devices are cost-effective fixed configuration customer premises equipment for service providers offering managed voice and data services. The Cisco IAD 880 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 IAD 880 Series provides secure concurrent services, including firewall, content filtering, VPNs, and WLANs, at broadband speeds to small offices. The Cisco IAD 880 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 IAD 880 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 Foreign Exchange Station (FXS) or Basic Rate Interface (BRI) voice ports over asymmetric DSL (ADSL) or G.SHDSL furthers the appeal of the Cisco IAD 880 Series to service providers for providing managed services.
