Configuration sub-system for telecommunication systems

A method performed by a device associated with a distributed antenna system, the device comprising a downlink signal path configured to receive a downlink service signal sourced from a base station, to adjust a signal gain of the downlink service signal, and to output the gain-adjusted downlink service signal, the method comprising:

• selectively providing a test signal to the downlink signal path of the device from a test signal generator integrated into the device comprising the downlink signal path configured to receive the downlink service signal sourced from the base station and to adjust the signal gain of the downlink service signal, wherein the downlink signal path is configured to be communicatively coupled to the base station;
• and
• measuring a power of the test signal at a measurement point in the downlink signal path of the device using a power measurement device integrated into the device comprising the downlink signal path configured to receive the downlink service signal sourced from the base station and to adjust the signal gain of the downlink service signal.

A method performed in a remote antenna unit of a distributed antenna system, the remote antenna unit comprising an uplink signal path configured to receive an uplink service signal from at least one antenna associated with the remote antenna unit, to adjust a signal gain of the uplink service signal, and to output the gain-adjusted uplink service signal for communicating to a base station via the distributed antenna system, the method comprising:

• selectively providing a test signal to the uplink signal path from a test signal generator integrated into the remote antenna unit comprising the uplink signal path configured to receive the uplink service signal from at least one antenna associated with the remote antenna unit and to adjust the signal gain of the uplink service signal, wherein the test signal generator is positioned outside the uplink signal path;
• and
• measuring a power of the test signal at a measurement point in the uplink signal path of the remote antenna unit using a power measurement device integrated into the remote antenna unit comprising the uplink signal path configured to receive the uplink service signal from at least one antenna associated with the remote antenna unit and to adjust the signal gain of the uplink service signal.
