Legacy MTU/MDU migration to VoIP based networks
The SN4300 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 net-
works. 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 net-
works.
Above all, it allows simple and transparent migration process for enterprise and residential customers in the
MTU/MDU facilities.
