A method for allocating time slots of a shared schedule for a plurality of communication lines having a crosstalk relationship is described. A first number of allocated time slots is allocated, according to respective priorities, corresponding to a first time interval for first data to be transmitted. The first data is transmitted. A second number of allocated time slots is allocated, corresponding to a second time interval for second data to be transmitted. The second number is larger than the first number if an allocation increase threshold has been met, based on utilization of a first time slot having a lowest priority of the first number of allocated time slots. The second number is smaller than the first number if an allocation decrease threshold has been met, based on utilization of a second time slot having a higher priority than the first time slot.

A structure protects a SLIC telephone line interface against overvoltages lower than a negative threshold or higher than a positive threshold. The structure includes at least one thyristor connected between each conductor of the telephone line and a reference potential. For all of the included thyristors, a metallization corresponding to the main electrode on the gate side is in contact, by its entire surface, with a corresponding semiconductor region. Furthermore, the gate of each thyristor is directly connected to a voltage source defining one of the thresholds.
