Реферат: ABSTRACT OF THE DISCLOSURE A t.d.m. exchange system comprising a transmitting and a receiving store for use in the temporary combination of subsidiary channels to form a transmission channel possessing a higher chan-nel capacity than the individual subsidiary channels and for the characterisation of the operating mode on said higher capacity transmission channel. An item of command information formed in said exchange system is recorded, together with an additional criterion, into a storage cell, assigned to an unseized subsidiary channels, of the transmitting store, and is transmitted via a data channel connected to the exchange system. On the reception of a piece of command information in said exchange, at least two equi-distant subsidiary channels are combined to form a higher capacity transmission channel, and the operating mode for the subsequent data transmission is set. On the reception, in said exchange, of a connection clearing signal relating to a connection being con-ducted via a higher capacity transmission channel, said channel is broken up into its constituent subsidiary channels.
