A telecommunications system is disclosed for extending the range of at least two service networks having different specified signalling standards. The telecommunications system includes a radio-based access network which includes at least one port to each service network. The ports are connected to at least one base station in the access network. The access network also includes a radio-based access network part capable of connecting the base station to a radio unit in the access network. The radio unit is registered in one of the service networks, the so-called home network of the radio unit, and a signal carrier in the access network has a first terminal point in the radio unit and a second terminal point in a port which connects the access network with the home network. The port functions to combine the signal carrier in the access network with a signal carrier in the home network.
