Abstract: A transfer device for transferring digital data, in a communication system, between a first network and a second network. The device includes a first interface with the first network, a second interface with the second network, a third interface with a transfer controller for controlling the transfer of digital data through the transfer device, and a fourth interface arranged to be connected to at least one transfer memory. The transfer device is configured to activate successively, in a respectively exclusive manner: a first transmission channel through the first and fourth interface, a second transmission channel through the third and fourth interface, and a third transmission channel through the second and fourth interface.
