The SmartNode 2400 VoIP Media Gateway provides a high density, seamless link between the circuit-switched telephone network and Voice-over-IP. Ideal for multi-service carrier and corporate PSTN access, the SmartNode 2400 takes 120 calls from voice-to-packet. With dual 10/100 Ethernet ports and four voice interface slots, the SmartNode 2400 connects to any switch, PBX, or data network.

The SmartNode delivers VoIP that has the clarity of toll-quality voice. Multiple user-defined G.711 and G.726 voice codecs are included, as well as G.723 and G.729ab for low bandwidth voice. T.38 FoIP, fax bypass, and modem bypass capabilities ensure that the SmartNode 2400 will seamlessly connect to all voice and data services. QoS ensures optimal voice performance through traffic classification and prioritization.

Patton?s exclusive Telephony-over-IP? (ToIP?) programmable circuit switching delivers service transparency and flexible PSTN integration. With ToIP any BRI, T1/E1 PRI, or FXS port can connect to any telephone or media gateway port.

Configuration Example: Shared-Switch Access
To take advantage of emerging technologies and the changing regulatory environments, network service providers are providing new services which can be integrated within the enterprise to reduce costs and improve service. Deployed as a trunk gateway, the SmartNode is the seamless link between the PSTN and VoIP access. Subscribers now access new carrier services without incurring charges from the incumbent carrier.

In enterprise networks, the SmartNode integrates telephony and IP data communications for best use of bandwidth, improved office-to-office communication, and reduced network costs.

Instead of installing a separate PBX in a remote office, the SmartNode is able to provide transparent extension of PBX phones. The extension can be managed centrally and benefit from services such as calling groups, least cost routing, and call forwarding.
