The invention concerns an electronic franking machine comprising franking means and means for recording the number of franking operations. The driving module has an adsorption mode and a display mode. Each logical router partition expression of the input command message is translated into a physical router expression, and the input command message, including any translated expressions, is propagated toward the router. A controller is provided for controlling the various elements of the apparatus. This protein shares significant homology with neuralized proteins, and associates with a number of muscle proteins, including \u03b2-catenin. The interface also emulates the input and output impedances of the IBP transducer which the IBP monitor is configured to work with.
