Zusammenfassung:	The invention relates to a method and a device for debugging xDSL line cards. An electrical connection is established by means of a test bus, between a line port to be tested and a testing line port which can be operated in the upstream and downstream direction with the same bandwidth. The testing line port is charged with a software which simulates a subscriber-side modem, and the successful establishment of a connection between the line ports represents a function confirmation for the line port to be tested.
