摘要
An apparatus for switching a user between an IP network and a PSTN is disclosed in the present invention and includes a user port, a Subscriber Line Interface Circuit, a detection circuit, a PSTN port, an IP network interface circuit and an action unit. A method for switching a user between the IP network and the PSTN is also disclosed. According to the method, the action unit is controlled by the control signal from a CPU, thereby implementing the user switching between the IP network and the PSTN on the apparatus. The apparatus and the method enable one or more users to switch between the IP network and the PSTN, implements flexible user selection between the two networks and offers user communication backup when failure occurs. Accordingly, the present invention increases the satisfaction of users and the core competence of enterprises.
