Abstract

A method for operating interface modules in an ATM communications device wherein interface modules which can be specified as active and/or redundant are connected to a central control unit. Control commands provided for this purpose are transmitted approximately simultaneously from the central control unit to the active and the redundant interface module during the establishment and clearing of at least one virtual connection, and the redundant interface module does not acknowledge receipt of the control commands. The load on the interface module is thus dynamically relieved.
