Solution Overview

Patton SN4400 VoIP Gateway Router

Patton Smartnode 4400 VoIP Gateway-Router

The Patton SN4400 series VoIP gateway router gives your system access to up to 32 FXS ports for connecting analog devices to your PBX such as analog telephones, fax machines, or modems. The Smartnode 4400 FXO gateway routers allow you to connect your VoIP phone system to up to 32 PSTN lines for local calling, failover, or a gradual migration to VoIP. The chassis features 2 10/100 Ethernet ports, a single internal power supply (UI or 48V DC) and a Telco connector.

Patton SN4400 Overview:

The SmartNode 4400 Series IpChannel Bank is the perfect business solution for applications requiring 12 to 32 concurrent analog voice/fax calls. Patton gateways transforms any PBX system, analog call-center appication, or ISP MDU service into a state-of-the-art packet-voice system without requiring costly equipment replacement or upgrades.

There are several models in the SN4400 Series—ranging from 12 to 32 FXS or FXO ports. The Patton 4400 series supports key industry-standard VoIP signaling protocols such as SIP, H.323, and T.38 Fax Relay—plus fax-bypass and modem-bypass. This ensures interoperability with the leading soft switches and VoIP services.

Built-in Quality of Service (QoS) features include voice prioritization and traffic management via configurable service-policy profiles. Patton’s advanced DownStreamQoS ensures clear, uninterrupted voice—even over best-effort networks such as the Internet. Packet classification using 802.1p, TOS, and DiffServ makes integration with existing managed QoS networks easy.

Create custom security profiles for a comprehensive security environment. IPsec (optional license) in the SN4400 Series delivers data integrity, authentication, anti-replay and data confidentiality. Firewall capabilities include Access Control Lists (ACLs), IP-address and port filtering, protection against Denial of Service (DoS) attacks, and use of second Ethernet port as DMZ.

Offering easy setup, reliable operation, and third-party interoperability on a proven platform, the SN4400 Series gateway sits at the core of cost-effective business solutions. The investment protection you need for the future is here today.
