Cisco CISCO3925/K9 overview

  • 1Description

The Cisco 3925 Integrated Services Router offers embedded hardware encryption acceleration, voice-and video-capable DSP slots, optional firewall, intrusion prevention, call processing, voicemail, and application services. Unified communications is enabled through a rich signaling and media-processing infrastructure, including a variety of protocols, media interworking, signal and media security, transcoding, conferencing, and QoS. The router features a wide range of voice-gateway interfaces, supporting a broad array of signaling and physical network interfaces. It supports wired and wireless connectivity options such as T1/E1, T3/E3, xDSL, copper, and fiber Gigabit Ethernet.

The 3925 Integrated Services Router offers excellent performance and flexibility for network deployments from small business offices to large enterprise offices, offering investment protection to customers. The modular architecture is designed to support increasing bandwidth requirements, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules supporting 802.3af PoE and Cisco ePoE. Most of the modules available on the previous generation 3800 Series Integrated Services Routers are supported on this router.

A single Cisco IOS Universal image encompassing all functions is delivered with the router. You can enable advanced features by activating software licenses (available separately) on the universal image. Technology packages and feature licenses, enabled through the Cisco software licensing infrastructure, simplify software delivery and decrease the operational costs of deploying new features.
