The invention relates to a telephone system with a ringer generator (16) for generating a ringer signal, an SLIC (2) that outputs a ringer voltage (Va,b) derived from said ringer signal over a transmission line (17) and at least one telephone. In order to reduce power loss in the ringer mode, the ringer generator (16) can be regulated and comprises a regulating device (14) for regulating the ringer voltage (Va,b) depending on the length of the transmission line (17). |
