The invention creates a method for adjusting a ringing signal current in a subscriber line ( 106 ), a ringing signal generator ( 114 ) which generates the ringing signal being connected with one end of the subscriber line ( 106 ) and at least one subscriber ( 102 ) being connected to another end of the subscriber line ( 106 ), comprising the steps of detecting a ringing signal current of the ringing signal; of comparing the detected ringing signal current with a predetermined current value; and when the detected ringing signal current is greater than the predetermined current value, reducing a ringing signal voltage of the ringing signal in such a manner that the ringing signal current is equal to the predetermined current value, the ringing signal voltage being dropped across the subscriber line ( 106 ) and a load of at least one subscriber ( 102 ). The invention also creates a circuit arrangement for carrying out the method.
