Abstract: Signals (14) are analyzed in appliance for bidirectional conversion between analog speech telephone signals and digital speech signals for transmission via data transmission network. A/D and D/A converters are part of appliance. Appliance contains also digital data processing, detecting digital signal and computing characteristic magnitudes of amplitude and/or time course of digital signal (14). Characteristics are transmitted from processor, containing programmable filter (16), via data network. Independent claims are included for appliance for bidirectional conversion between analog telephone speech signals and digital speech signals.

Abstract: A telephone system includes a transmission line for connection to at least one telephone and a telephone interface in communication with the transmission line. The telephone interface provides DC power when a telephone connected to the transmission line is in an off-hook state. A controller in communication with the telephone interface generates a pre-defined DC characteristic of the telephone interface, and a regulator in communication with the controller adaptively translates the DC characteristic.

Abstract: The invention relates to a method and an apparatus for controlling a digital signal processor having a number of arithmetic units (1a, 1b) which process a program (8). A control unit (5) is provided for independent control of the individual arithmetic units (1a, 1b), which control unit (5) reads and evaluates the flags (9a, 9b) which are specific to the arithmetic units, and deactivates those arithmetic units (1a, 1b) whose associated flag is not set, so that a subroutine is carried out only by those arithmetic units (1a, 1b) whose flags are set.

Abstract: The invention provides a transmission apparatus (100) for transmission of electrical signals between a line driver (205), which is connected to a transmission line (201), and a switching center (301), having an analog feedback device (101) for coarse setting of a line voltage level (210) on the transmission line (201), and a digital feedback device (102), which is coupled to the analog feedback device (101) and has a feedback filter device (118), designed such that a filter input signal (404) can be converted to a filter output signal (405) at a rate which is lower than the sampling rate (fa) of an analog/digital converter (104).

Abstract: The invention relates to a method for ascertaining a resistance value (Z) between a first contact (2) and a second contact (3) in a subscriber line interface circuit (4), where a protective circuit (9) for protecting the subscriber line interface circuit (4) against overvoltages is provided between the two contacts (2, 3) and comprises a parallel circuit containing a protective capacitor (5) with two resistors (7, 8) connected in series via a node (K), the node (K) being connected to a third contact (10) in the subscriber line interface circuit (4), where the method has the following steps: a predetermined charging voltage (UCharge) is applied to the protective capacitor (5); a threshold voltage (UTH) is calculated on the basis of the resistance values (R1, R2) of the two resistors (7, 8) and the applied charging voltage (UCharge); a measured voltage (UM) tapped off across one of the two resistors (7, 8) is measured while the protective capacitor (5) is discharging; the measured voltage (UM) is compared with the calculated threshold voltage (UTH); a period (Deltat) between the start of the discharging of the protective capacitor (5) and the time at which the measured voltage (UM) is the same as the threshold voltage (UTH) is ascertained; and the resistance value (Z) is calculated using the ascertained period (Deltat) and the resistance values (R1, R2) of the two resistors (7, 8).

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.
