The SmartNode 2300 Modular VoIP Access Router is a single flexible platform for network data and Voice-over-IP applications. Ideal for the branch office or the small to medium enterprise, the SmartNode 2300 is performance-tuned for packet and voice. Equipped with dual Ethernet ports, a serial V.35/X.21 port, and three voice interface slots, the SmartNode 2300 scales up to 60 simultaneous calls in a 1U chassis.

The SmartNode 2300 connects your LAN to the WAN using PPP or Frame Relay (RFC-1490) eliminating the need for and cost of an extra router. With dual Ethernet ports and built-in QoS, NAT, DHCP, PPPoE, and ACL/Firewall, the SmartNode 2300 provides complete LAN network access control.

With Patton’s Telephony-over-IP (ToIP) programmable circuit-switching the SmartNode links any standard BRI, T1/E1 PRI, or FXS connection to the IP network. Supporting multiple codecs and T.38/Modem bypass, the SmartNode seamlessly converges voice, data, and fax over IP.

The SmartNode delivers IP network access with the clarity of toll-quality voice for a complete LAN, WAN, and Gateway solution.

Configuration Example: Office IP & Voice Access
The SmartNode 2300 Modular VoIP Access Router is an intelligent multi-service access device providing both routed LAN services and Voice-Over capabilities.

With its internal router and V.35/X.21 port, remote or local sites can access public IP services or private data VPNs without the added cost of a router.

Adding Voice-Over capabilities are a snap using any combination of field-installable voice and data modules. Now any site can connect VoIP to any phone with BRI, T1/E1 PRI, or FXS.
