Abstract

A method of checking the main paths in a network of a centrally controlled telecommunication exchange that interconnects the blocks of the network and of the individual channels that serve for the transmission of messages or for control and signaling information, each path being main connected, at least at one of its ends, to a switching unit, characterized in that the control routes that interconnect the central control network with each block pass through the switching units used as switching points and along the roads In such a way that at least one channel of each main path is used as a control channel constituting a part of a control route, because control telegrams or signaling in both directions are permanently transmitted on all control routes between the central control network and the block and because the error-free transmission of these telegrams in a Control route is taken as an indication of the possibility of operation of all the main roads through which this control route passes.
