SmartNode 4130 ISDN BRI
VoIP Gateway


SmartNode™ ISDN BRI VoIP Gateway

The SmartNode 4130 series 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.

The SN4130 series comes with the option to have 2 Ethernet ports populated. This gives a clear upgrade path for converting the gateway into an eSBC. Models containing “SN4131/2ETH” are capable of accepting a software license to achieve this additional functionality future proofing your voice network for next generation SIP services and security. Interested in upgrading a 2ETH Gateway model to become an eSBC See the eSBC specs of the model SN5530.
