Circuit arrangement for telecommunication installations, especially for telephone exchanges comprising information processors and devices for overload control

摘要

In order to avert overloads of control units for groups of subscriber-associated or call-associated switching devices, the data required for such purpose and pertaining to the traffic load are respectively acquired within one of such groups. These data are the occurring occupations of calling subscribers. A respective counter, provided per group, is incremented with such data, the counter being continuously deincremented, cyclically, and transmitting an overload signal upon attaining a limiting value. Occupations that directly lead to the formation of the overload signal are rejected. Therefore a prophetic overload defense is provided.
