Abstract: A method of testing a communication line includes applying a voltage as a function of time on the communication line and measuring at least a first current and a second current flowing via the communication line. The second current is measured at a different point in time than the first current. The method includes deciding whether a given terminal element is connected to the communication line based on the first current and the second current.

Abstract: A control circuit for generating a supply direct voltage for an analogue telephone comprises an SLIC circuit and a CODEC circuit. An analogue telephone is connectable to the SLIC circuit via a two-wire telephone line and the SLIC circuit detects a loop direct current flowing through the two-wire telephone line when connected to the SCLIC circuit. The CODEC circuit comprises a constant voltage source for generating a constant voltage and a subtractor for generating a differential voltage by subtracting a voltage proportional to the loop direct current from the constant voltage. The differential voltage is amplified with a constant gain factor for generating the supply direct voltage.

Abstract: A system and method for testing a transmission line to a protected system includes measuring voltages between a tip-side node of an overcurrent protection device and the protected system, between a ring-side node of the overcurrent protection device and the protected system, between the tip of the transmission line and the protected system, and between the ring of the transmission line and the protected system. Using the measured voltages, the status of the overcurrent protection device and the overvoltage device may be recognized, and the magnitude of a voltage surge on either of the tip and ring wires may be determined.

Abstract: A signal generator is disclosed that generates a test signal to be applied to a first and second wire of a subscriber line. The signal generator is configured to generate the test signal at the first and second test signal outputs in a first time section such that a first potential at the first test signal output is changed from a first value to a second value and a second potential at the second test signal output is maintained constant at least during the change of the first potential. The signal generator is further configured to generate the test signal during a second time section such that the first potential at the first output and the second potential at the second output are oscillating with a predetermined frequency.
