A method and apparatus for the supervision of connections in storage-programmed telecommunication switching installations for binary coded messages is described. The information identifying transmitters to be supervised is recorded at permanently assigned storage locations such that the assigned location will be checked first. Only when the stored information demands supervision, the bit combination which is contained in the word stored therein, is checked in a program control and changed. The changed bits are recorded in each case during a single storage cycle through operations similar to the logic OR operation, taking place at the store itself, the changed bits being recorded into the assigned storage location. Therefore, only those transmitter cells are tested which are to be supervised, and erroneous over-writing is avoided.
