Abstract
An interface module () for a unit () which is designed to transmit and/or amplify essential communication signals inside an antenna distribution system () is specified, said module comprising a first analog interface () for forwarding and receiving essential communication signals from mobile terminals (), a second interface () for forwarding and receiving essential communication signals from the antenna distribution system (), at least one signal path () for forwarding the received communication signals between the two interfaces (), and a controllable digital unit () which incorporates the signal path () and has means for digitizing incoming communication signals and for subjecting outgoing communication signals to analog conversion. In this case, the digital unit () is designed to identify essential communication signals in the digitized communication signals, to mask the remaining signals and to forward the essential communication signals. An antenna distribution system () having at least one master unit () and a number of remote units () which are connected to the latter and are equipped with such an interface module () is also specified. The invention makes it possible to use the advantages of a modern radio network architecture to communicate on essential communication channels.
