Terminal connection device for detecting operating mode change of e.g. digital subscriber line subscriber terminal, has unit to control switching devices, so that interfaces are connected by Internet protocol-based communication path

摘要

The device (10) has a control unit (20) controlling switch devices (50, 55) in such a manner that two interfaces (40, 45) are connected by a galvanic communication path. The control unit controls the switching devices by activating a physical state, which is detected by a detector device i.e. line detector (30), and signalizes Internet protocol-based operation of a subscriber terminal, so that the interfaces are connected by an Internet protocol-based communication path. A hook detector (100) is assigned to one of the interfaces.
