G.SHDSL Converged CPE/IAD Products
SmartNode SN4990A PRI VoIP IAD | 1 or 4 T1/E1/PRI interface for up to 120 simultaneous phone or fax calls with Fiber, G.SHDSL, X.21, ADSL/VDSL

Now service providers can reach more enterprise subscribers with All-IP services. The SmartNode 4990 VoIP Integrated Access Device (IAD) connects any existing telephony system to SIP trunks and the PSTN.

Cloud Enabled
The SmartNode™ 4990A VoIP Integrated Access Device for 15-to-120 VoIP calls lets enterprises graduate to All-IP at their own pace. The one-box solution includes a built-in G.SHDSL-EFM/ATM, VDSL/ADSL, fiber, or X.21 WAN interface for broadband access. Legacy telephony interfaces enable SIP trunk providers to offer their All-IP services to businesses that want to keep an existing PBX solution, while providing PSTN connectivity for voice and data survivability. 

The integrated WAN-access options reduce CPE costs, simplify network architecture, and accelerate service deployment.  A SIP back-to-back user agent provides SIP normalization that ensures interoperability between any customer PBX and any provider softswitch on the market. Built on a platform that is ready to support IPv6, the SN4990A provides secure TLS and SRTP encryption* while supporting all the industry-standard CODECs for 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 technology (with voice encryption) provides secure voice and data via IPsec with AES/DES strong encryption and automated keying via Internet Key Exchange (IKE) and OpenVPN*. Advanced call-router functionality includes least-cost call routing with flexible dialed-number plan support.

The SmartNode survivability suite combines PSTN fallback, SIP Registrar,  IP-link redundancy and active SIP server reachability detection to ensure business continuity in case the IP network fails, while Patton’s DownStreamQoS™ delivers clear, uninterrupted voice-and-data communication. Patton’s unique high-precision clock delivers first-line IP-telephony service in demanding ISDN and DECT environments—with reliable FAX and modem performance.

Strong number-portability delivers a smooth transition to VoIP by accepting incoming calls from the PSTN throughout the number-porting process. Session border router capabilities include optional transcoding for up to 64 channels. Reduce WAN-access bandwidth requirements by converting high-bandwidth G.711 calls on the enterprise LAN into lower-bandwidth G.729 calls for WAN transport.

The SN4990A delivers secure, prioritized unified communications with one to four T1/E1/PRI and two 10/100/1000 Ethernet ports—plus broadband access—in a single box.  An optional third 10/100 Ethernet port may connect to an out-of-band IP management network, or—for enhanced survivability—provide a redundant Ethernet connection to the (same or alternate) service provider.
