Patton SmartNode 4991 4 T1/E1 PRI VoIP IAD 60 Channel - 4 T1/E1 PRI VoIP IAD - X. 21 SN4991/4E60VRD/EUI 2x GigEthernet - 60 VoIP channels - not upgradeable - Failover Relay - External UI Power - IPv6 ready - High Precision 5ppm Clock Source Patton SmartNode 4990 PRI Enterprise VoIP IAD. Management protocols: Web/HTTP, CLI, HTTP/TFTP, SNMP, Routing protocols: BGP, RIP-2. Ethernet LAN data rates: 10,100, 1000 Mbit/s, Networking standards: IEEE 802.1Q, IEEE 802.1p. Weight: 850 g, Dimensions (WxDxH): 301 x 181 x 45 mm. Power consumption (typical): 15 W, Input frequency: 50 - 60 Hz, Input voltage: 100 - 240 V The SmartNode 4990 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 SN4990 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, 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 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 SN4990 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. - Trinity OS—Optional, select this when SIP TLS/SRTP is required. Software Comparison- 15 to 120 VoIP calls—with up to four T1/E1/PRI ports and dual Gigabit Ethernet ports. - Survivability—PSTN failover using ISDN lines or alternate WAN link. SIP server health detection with instant failover call routing. SIP registrar for local calling during failover. - QoS and Security—Deliver secure, toll-quality voice communications with Patton’s DownStreamQoS, Fraud prevention, secure voice-over-VPN with IPsec, OpenVPN. - WAN Access—Fiber SFP, G. SHDSL-EFM/ATM, Serial X. 21, Fast Ethernet or VDSL/ADSL WAN interface. - SIP Interop and Normalization—SIP interop with major IP PBX, softswitch and VoIP service providers. Over 100,000 SmartNode deployments worldwide. ISDN/PSTN compliance in nearly every country. - High Precision Clock—Delivers DECT PBX interoperability with reliable fax performance. - VoIP Transcoding Option—Up to 60 channels for WAN bandwidth optimization. - Transparent Telephony Features—Complex number manipulation and mapping for seamless integration with existing infrastructures, CLIP, CLIR, hold, transfer and much more. - Flexible Mounting Options—The device can be placed on a desktop or installed in a 19-inch rack using the optional rack ear kit (INS-KIT-RACKEARS-11/19). - Supported by SmartNode Redirection Service: A free service enabling zero-touch mass deployments for Service Providers and Distributors with auto-provisioning servers.
