The apparatus (10) has subscriber units (14) established for execution of modulation of subscriber current (IT) corresponding to a communication protocol. A coupling device (17) and/or the subscriber units are formed to perform another modulation of coupling device current (IK) flowing into the coupling device, where gradient of the subscriber currents in the former modulation lies above a gradient maximum value of the latter modulation. The gradient of the currents in the latter modulation is limited to the gradient maximum value. |
