Abstract: A method for simulating an electric circuit comprising components and receiving external stimuli, wherein the determination at a given time of the voltages at the circuit nodes comprises several iterations, each consisting of defining a probable voltage for each node, of calculating the currents of each component based on the component model, then of repeating until the mesh equation is verified, and wherein for the first time, a current of a component is calculated based either on the full accurate model, or on the simplified linear model, or on the compound model which is a fitting, according to the interval between the voltages at the component's terminals between the initial time and the first time, and the simplified, full or compound model is used respectively if the interval is smaller than a first threshold, greater than a second threshold or between the first and second thresholds.

Abstract: A line powered telephone interface circuit answers an incoming call and, responsive to a command tone, routes the call to a selected terminal. If no command tone is received within a predetermined time period, low voltage audio signalling devices located near the conventional telephone sets are activated to alert the subscriber of an incoming call. The interface need not be connected to a separated supply source. The device is connected to a telephone line and to at least one plug connectable with a telephone set jack, the device being connected to various terminals. A detector detects the ring signal and a relay establishes connection with a telephone line as soon as the ring signal has been detected for a determined time duration. A combination timer/switcher circuit inhibits the ringing of the corresponding telephone set, and is associated with a sound transducer connected operable by a low voltage signal.
