Patton SN4131/2BIS4VHP/EUI

The SmartNode 4131 are the next-generation ISDN BRI models of the proven market-leading SmartNode VoIP product family. The available 2, 4 or 8-port configurations fit the requirements of small and medium-sized enterprises looking for a cost-effective way to bridge PBX systems on multiple sites or connect them to a public Internet telephony service. By connecting a PSTN line and an ISDN PBX to the SmartNode, it is secured against SIP trunk outages (fallback routing). If available, the PSTN line can also synchronize the gateway. For applications without a PSTN line available, the optional ISDN HP (high precision clock) provides error-free ISDN data and fax transmissions. Like every Trinity SmartNode, the SN4131 comes with a built-in WEB Wizard for fast and easy configuration. You can build your own Web interface usingthe WEB Wizard functionalities.
