Abstract:
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.
