    摘要： 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.

    摘要： 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.

    摘要： A control device includes a circuit operable to sense an analogue input voltage dependent on a line current flowing via a communication line of a terminal generate an analogue difference voltage in a constant line current operation based on a difference between the sensed analogue input voltage and an analogue feedback voltage which depends on an adjustable nominal direct-current value and filter a sequence of control error values from a sequence of digital difference voltage values converted from the generated analogue difference voltage. The circuit is further operable to convert a control value generated from the sequence of control error values in the constant line current operation to an analogue direct voltage for supplying the terminal and convert the nominal direct-current value into the analogue feedback voltage in the constant line current operation.
