A method of testing a telecommunications line by using the following method. Applying a first AC test signal to a communications line (7) by tone generator (23) having a first frequency and then measuring the response to the first test signal. Applying a second AC test signal to the same communications line (7) with a different frequency and measuring the response. Calculating one or more line parameters based on the two measured responses.
