SmartNode 4660 and 4670 Series Overview
The SmartNode 4660 VoIP Gateway-Router and SmartNode 4670 VoIP IAD offer flexible combinations of
ISDN BRI, analog FXS/FXO, and Ethernet/IP interfaces to deliver a unique solution allowing the Enterprise
to IP-enable legacy ISDN-PBX and analog phone/fax/answering machine and audio-intercom systems. The
SN4670 model also includes a G.SHDSL, ADSL, EFM or Fiber interface for broadband access to deliver a sin-
gle-box CPE solution.
Providing 4 Ethernet, 2 to 8 BRI, 4 to 8 FXS, and up to 4 FXO ports, the SN4660 and SN4670 inter-connect
any Ethernet switch, ISDN PBX, analog equipment or IP-data network to support 8 to 24 simultaneous VoIP
calls using SIP, FXS/FXO or BRI signaling. The 10/100 Ethernet uplink provides seamless WAN access via any
existing cable, ADSL, VDSL, EFM, or fiber-optic modem. Additionally, the SN4670 model’s built-in 4-wire
G.SHDSL (11.4 Mbps), ADSL (up to 24 Mbps), EFM (up to 22.8 Mbps) or Fiber (up to 1000 Mbps) inter-
face provides seamless WAN access.

Like every SmartNode, the SN4660 and SN4670 support every industry-standard CODEC to deliver toll-
quality voice on every call. Adding session border controller capabilities, the SmartNodes include IP transcod-
ing for up to 12 SIP channels. 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 networks—plus T.38 and SuperG3 FAX). VoIP-over-VPN with voice encryp-
tion provides secure voice and data via IPsec with AES/DES strong encryption and automated keying via Inter-
net Key Exchange (IKE). In addition, 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 if the IP network fails. Patton’s DownStreamQoS delivers the advantage of clear, uninter-
rupted 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 perfor-
mance. 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.
