Bulk analog line extensions
The SN4400 FXS models used in combination enable enterprises to extend up to 32 analog phone lines over any IP link – be it the public Internet, a leased line or a WiMax link. 600kBit/s bandwidth are enough for 32 simulta- neous voice or fax conversations, using G.723 compressed voice transmission.
Advanced quality of service (QoS) features ensure optimal bandwidth usage and voice quality, even on small band- width links and with simultaneous transport of data or VPN traffic between the SmartNodes.

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 vari- ous 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.
