    Abstract: A summing unit within telecommunications system includes: port to receive digital data stream from another device; and summer function. Digital data stream includes first and second digital data derived from first and second base station. First and second digital data comprises first and second digital values associated with respective time periods. Summing unit extracts first digital data from digital data stream. Summer function digitally sums first digital data with third digital data derived from third base station to generate summed digital data for conversion to radio frequency signals and transmission at antenna. Third digital data comprises third series of third digital values associated with respective time periods. Summer function digitally sums first digital data with third digital data by digitally summing (i) first digital value associated with respective time period and (ii) third digital value associated with respective time period to produce summed value for respective time period.
