<p>A modem (40) and a method for controlling the same. The modem (40) includes a first interface (30) interfacing with a subscriber terminal (12), a second interface (70) interfacing with a switching system (22), a detection means (53) detecting a communication connection status with the subscriber terminal (12) and outputting a detection result signal, and a controller (62) processing a data communication between the subscriber terminal (12) and the switching system (22) and controlling the second interface (70) to stop the operations if a non-connection signal is inputted from the detection means (53). In the present invention, releasing a communication channel with the switching system (22) when the subscriber terminal (12) is in a non-connection status reduces unnecessary power consumption and lengthens the life span of an apparatus. Further, the operations of such subscriber modem can control unnecessary line occupation in a switching system for a plurality of subscriber modems, to reduce power consumption in the switching system and enhance system data processing speed. <IMAGE></p> |
