A method for measuring the operating characteristics of a subscriber line - assembly for high-bit-rate data transmission

摘要

For measuring the operating properties of a subscriber line module (1) for high bit rate data transmission, a test signal is generated within the module and supplied into a test line (6) with a defined line termination (7) who line or terminating properties are known. The echo signal arising in the test line (6) as a result of the test signal is in turn detected in the subscriber line module (1) and interpreted for evaluating the operating properties.
