The business-class SmartNode 4110 VoIP Media Gateway supports up to eight transparent phone calls and leverages VoIP for carrier and corporate access. Connecting to any analog phone, fax, or PBX, the SN4110 is an effective and flexible solution for toll-bypass, remote/branch office voice connectivity, and enhanced carrier services. The SN4110 Series is the perfect choice for phone-to-IP connectivity supporting up to 8 FXS ports or a combination of 4 FXS and 2 or 4 FXO ports. With its FXS analog ports, the SN4112S connects to any legacy telephone or PBX and provides dial-tone, ringing, and caller-ID. When equipped with FXO ports, the local PSTN can be accessed enabling local calling and enhanced toll-bypass applications while using a single connected telephone. Flexible call integration allows per-port telephone numbers, programmable call progress tones, and distinctive ringing. With Telephony-over-IP (ToIP) call switching, calls can automatically select the least-cost-route while providing flexible numbering plans and end-to-end feature transparency. PPPoE, DHCP, and VLAN offers universal IP connectivity and optional IPsec?VPN with AES/3DES guarantees secure voice over the public network. Patton’s SmartNode SN4110 Series delivers the legacy phone interfaces, service transparency, and flexible PSTN?integration required for true converged packet voice. In enterprise networks, transparent access to PBX features while using existing equipment is key to low-cost operations. Now, instead of installing a separate PBX at the remote office, the SmartNode 4110 Series is able to provide transparent extension while simultaneously connecting multiple locations. The extensions can be managed centrally and benefit from PBX?services such as calling groups, least cost routing, and call forwarding. PSTN?access allows local calls to be processed without using corporate remote PBX resources. ?Additionally, the corporate PBX can break-out and bypass any long distance charges by using the remote office for the local gateway.
