PATTON SN4634/3BIS/EUI SmartNode 4600 Series VoIP Gateway / ATA
Patton SN4634/3BIS/EUI ISDN2 VoIP gateway with 3 BRI ports.
The Patton SN4634/3BIS/EUI is an ISDN2 VoIP gateway designed to bridge legacy ISDN Basic Rate Interface (BRI) circuits with modern IP-based voice networks. This unit provides 3 BRI ports, enabling connectivity for ISDN terminal equipment or PBX trunk lines to SIP-based VoIP infrastructure.
This gateway is commonly deployed in enterprise environments where existing ISDN infrastructure must be preserved whilst transitioning to IP telephony. It serves as a critical integration point between traditional TDM-based telephone systems and SIP trunking providers or hosted VoIP platforms.
The SmartNode 4600 series from Patton is well-established in the enterprise voice market, offering reliable protocol conversion and voice quality management. The EUI suffix indicates this unit is configured for European ISDN standards, making it suitable for UK and European deployments.
