SmartNode Hi-Cap 4 T1/E1/PRI VoIP IAD, 2x GigEthernet, 30 VoIP channels; field upgradeable to a max of 60 channels. 2 Pairs G.SHDSL interface, External UI Power, High Precision 5ppm Clock Source
As enterprises move move
toward Unified Communications, the SmartNode™ 4950 offers a smooth transition to
IP telephony by connecting your traditional phone equipment to next-generation
VoIP networks and services.
Preserve your investment in legacy phone equipment while taking the next step toward Unified Communications. Least-cost call routing in Patton’s proven SmartNode™ VoIP solutions optimizes monthly expenses while flexible dialed-numbering plans maintain established business processes.
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) combined with dial-backup and IP-link redundancy for VoIP and data survivability. Provide VoIP-over-VPN security with voice encryption via IPsec with AES/DES strong encryption and automated keying via Internet Key Exchange (IKE), plus SIP Registrar for presence/reachability.
Advanced router functionality includes DownStreamQoS™ delivering the clear advantage of secure, uninterrupted voice-and-data communication.
Connect to any switch, PBX or data network with up to four T1/E1/PRI ports for up to 120 simultaneous calls using SIP, T1, E1 or PRI signaling. Like every SmartNode, the SN4950 supports all the industry-standard CODECs, delivering toll-quality voice on every call.
Ensure business continuity. Combining PSTN breakout with IP-link redundancy, SmartNode™ ensures voice-and-data survivability for reliable enterprise-class communications.
Additional options include Patton’s unique high-precision clock enabling first-line IP telephony services in demanding ISDN and DECT environments with reliable FAX and modem performance. The SN4950 also offers optional built-in 11.4 Mbps broadband access via 4-wire G.SHDSL.bis that reduces hardware costs, simplifies network architecture and streamlines service and deployment.
