Patton IpChannel Bank 4416 (16 VoIP calls) – SN4416/JO/UI


Patton SmartNode IpChannel Bank 4416 (16 VoIP calls) – SN4416/JO/UI Summary

The models in the SN4400 Series are available with up to 32 FXS or FXO ports. The SN4400 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 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 IpChannel Bank sits at the core of cost-effective business solutions. The investment protection you need for the future is here today.

Legacy is not bad! While VoIP offers distinct advantages in almost every aspect of communications, in many cases it is appropriate to integrate legacy equipment into a VoIP system rather than replacing it. The SN4400 Series is the enabler to protect your investment in the analog equipment. It enables enterprises to extend multiple analog lines from a PBX to a remote location with existing cabling or phones, taking advantage of a single IP link to transport up to 32 voice calls. The remote location can be a building around the block as well as a partner in another continent.

The SN4400 IPChannel Bank offers an ideal way for Service Providers (SP) to migrate their existing networks to standards based VoIP networks. By using the Telco Connector port, the existing closet wiring in the MTU/MDU can be utilized and the customer’s analog devices can now be connected to feature rich VOIP-based networks. This protects the investments that have been made in analog equipment and wiring by various MTU/MDU facilities and leverages it further by connecting these facilities to the Service Provider’s VoIP-based networks.
