The Cisco AS5300 is an award-winning dialup remote access server and voice-over-IP (VoIP) gateway. When equipped with voice feature cards (VFCs) and voice-enabled Cisco IOS® software, the AS5300 supports carrier-class VoIP and fax over IP services.
Cisco IOS (Internetworking Operating System) software offers a powerful array of quality-of-service (QoS) mechanisms, variable frame sizing, and standards-based H.323 controls, which provide industry-leading voice quality and call control routing to deliver enhanced services. Mier Communications testing rated the voice-over-IP gateway capabilities of the Cisco AS5300/Voice Gateway as best in the areas of voice quality, latency, and bandwidth requirement.
In addition to being H.323 compliant, the Cisco AS5300/Voice Gateway supports a family of industry- standard voice CODECs and provides echo cancellation and voice activity detection (VAD)/silence suppression. It offers an integrated interactive voice response (IVR) application that provides voice prompts and digit collection in order to authenticate the user and identify the call destination. Users can readily interface with Public Switched Telephone Network (PSTN) digital switches or PBXs, and existing RADIUS authentication and billing servers.
The Cisco AS5300 voice/fax feature cards are coprocessor cards, each with a powerful Reduced Instructions Set Computer (RISC) engine and dedicated, high-performance digital signal processors (DSPs) to ensure predictable, real-time voice processing. The design couples this coprocessor with direct access to the Cisco AS5300/Voice Gateway routing engine for streamlined packet forwarding. The Cisco AS5300/Voice Gateway can accept two voice/fax feature cards, so the Cisco AS5300/Voice Gateway can scale up to 96/120 voice connections within a single chassis.
