The high precision SmartNode 4971 models have a Stratum III clock. The Stratum III clock provides a clock source of < 5 ppm. For PBXs that used to rely on PSTN for accurate clock source, the SmartNode 4971 can provide a PSTN-equivalent high precision clock. The popular DECT PBX needs such high precision clocks.

4970 VoIP Gateway offers Enterprises a cost-effective
solution to IP-enable their legacy PBX systems. Evolving from
Pattons award winning SmartNode 4940 Series, the next generation
SmartNode 4970 Series comes now with IPv6 upgradeable hardware.
Like every SmartNode, the SN4970 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, H.323, ISDN, and POTS calls with routing and conversion between TDM/PSTN and IP/Ethernet networksplus T.38 and SuperG3 FAX). VoIP-over-VPN with voice encryption provides secure voice and data via IPsec with AES/DES strong encryption and automated keying via Internet Key Exchange (IKE). In addition, advanced call-router functionality includes least-cost call routing with flexible dialed-number plan support.
The SmartNode survivability suite offers PSTN fallback to ensure business continuity in case the IP network fails. Furthermore, SmartNodes 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 VoIP with strong number portability support accepting incoming calls from the PSTN throughout the VoIP service provider's number porting process.
Preserve investments in legacy phone equipment while taking the next steps toward unified communications with the SN4970 VoIP Gateway. Providing 1 to 4 T1/E1/PRI and a 10/100/1000 Ethernet for up to 120 VoIP calls, the SN4970 delivers a reliable, cost-effective solution for the Enterprise.
