Abstract
Signals of different transmission speeds are switched within a program-controlled data exchange system. The exchange system has connection circuits and/or connection circuit groups which are connected to either lines which supply the relevant signals and trunk lines which feed the signals forward. A switching arrangement which receives the signals supplied by the feeder lines to the connection circuits or connection circuit groups emits the signals to the desired truck lines by way of the connection circuits or connection circuit groups in question and carries out switching processes in response to switching requests from the connection circuits or connection circuit groups. Signals falling into one and the same transmission speed class are transmitted via one and the same connection circuit or connection circuit group, and the connection circuit or connection circuit group which serves to receive and/or emit signals belonging to the highest transmission speed class is connected to the switching arrangement for the handling of switching requests having priority over the other connection circuits or connection circuit groups. After the connection circuit or connection circuit group for the highest transmission speed have handled switching requests, all the other connection circuits or connection circuit groups are connected, in alternation with one another, to the switching arrangement for the handling of their own switching requests.
