SKU: 4402 Category:





Cloud Enabled The SmartNode™ SN4980A/4E120VRHP/EUI VoIP Gateway-Router-eSBC allows Enterprises to IP-enable their legacy PBX systems. Evolving from Patton’s award winning SmartNode 4980 Series, the next generation SmartNode 4980A Series comes now with more state of the art features such as SIP-TLS, SRTP, TR-069, Patton Cloud connect, Survivability features, and much more. The SN4980A/4E120VRHP/EUI is a member of the SN4980A product series.

Like every SmartNode™, the SN4980A/4E120VRHP/EUI supports every industry-standard CODEC to deliver toll-quality voice on every call. The Unified Communications Agent™ (UCA) provides any-to-any multi-path switching (simultaneous SIP, ISDN, and POTS calls with routing and conversion between TDM/PSTN and IP/Ethernet networks—plus T.38 and SuperG3 FAX). VoIP-over-VPN with voice encryption provides secure voice and data via IPsec, OpenVPN, or L2TP tunneling protocol in addition to SIP-TLS & SRTP. The advanced call-router functionality includes least-cost call routing with flexible dialed-number plan support.

The SmartNode survivability suite combines PSTN fallback, SIP Registrar and IP-link redundancy to ensure business continuity in case the IP network fails. Patton’s DownStreamQoS™ delivers the advantage of clear, uninterrupted voice-and-data communication. Furthermore, SmartNode’s unique high-precision clock delivers first-line IP telephony service in demanding ISDN and DECT environments with reliable FAX and modem performance. In addition, SmartNode delivers a smooth transition to All-IP with strong number portability support accepting incoming calls from the PSTN throughout the VoIP service provider's number porting process. Enterprise Session Border Controller capabilities include transcoding for up to 60 channels, SIP service demarcation, and SIP security. Reduce WAN-access bandwidth requirements by converting high-bandwidth G.711 calls on your LAN into lower-bandwidth G.723 calls for WAN transport.


Preserve investments in legacy phone equipment while taking the next steps toward All-IP unified communications with the SN4980A/4E120VRHP/EUI  VoIP Gateway-Router-eSBC. Providing four T1/E1/PRI and two 10/100/1000 Ethernet ports for up to 120 VoIP calls, the SN4980A/4E120VRHP/EUI with built-in IP Router delivers secure, prioritized unified communications.
