Interface module for a unit of an antenna distribution system, and antenna distribution system
First Claim
1. An interface module for a unit designed to transmit and/or amplify communication signals inside an antenna distribution system the interface module comprising:
- a first analog interface for forwarding and receiving communication signals from mobile terminals;
a second interface for forwarding and receiving communication signals from the antenna distribution system;
at least one signal path for forwarding the received communication signals between the first and second interfaces;
a controllable digital unit which incorporates the signal path and digitizes incoming communication signals and subjects outgoing communication signals to analog conversion, the digital unit being configured to evaluate characteristic signal parameters of the communication signals and identify essential communication signals in the digitized communication signals from remaining communication signals, and further configured to mask the remaining communication signals and to forward the essential communication signals;
a communication unit configured to interchange information and control data between a master unit and the controllable digital unit for controlling operation of the digital unit.

Abstract
An interface module (4) for a unit (1, 2) which is designed to transmit and/or amplify essential communication signals inside an antenna distribution system (29) is specified, said module comprising a first analog interface (6) for forwarding and receiving essential communication signals from mobile terminals (32), a second interface (7) for forwarding and receiving essential communication signals from the antenna distribution system (29), at least one signal path (9, 10) for forwarding the received communication signals between the two interfaces (6, 7), and a controllable digital unit (11) which incorporates the signal path (9, 10) and has means for digitizing incoming communication signals and for subjecting outgoing communication signals to analog conversion. In this case, the digital unit (11) 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 (29) having at least one master unit (2) and a number of remote units (1) which are connected to the latter and are equipped with such an interface module (4) is also specified. The invention makes it possible to use the advantages of a modern radio network architecture to communicate on essential communication channels.
