SmartNode IpChannelBank 32 FXS VoIP GW-Router, 2x10/100bTX, 48V DC Power

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


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.

For call centers, the SN4400 is the ideal, reliable solution to integrate legacy work desks and cabling into next-generation, VoIP-based call center software.


Legacy MTU/MDU migration to VoIP based networks
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.

Above all, it allows simple and transparent migration process for enterprise and residential customers in the MTU/MDU facilities.
