ABSTRACT:
In a telephone exchange system comprising information-processing sequential logic systems and devices for averting overloads, the group processor requests which occur for the incoming through-connections are rejected first given a necessity of an overload defense system and with an overload of a first degree, the request being the through-connection request to be executed, respectively, once incoming and once outgoing (with reference to the respectively-employed subscriber line or trunk or, respectively, corresponding channels) over line trunk groups per connection. Requests by group control unit for outgoing through-connections are likewise rejected only given an overload of a second degree. Discrimination of the two overload levels is provided by way of a counter.
