M4 Documentation:

Preparation of the calldetails data, part one. Here the three six-months-periods used for mining are marked with a new attribute indicating the period, plus a new attribute indicating the number of the month in that period (1 to 6). This makes parallel processing with the help of Segmentation easier in the following chain (HandleCallsDataComputeSums). In addition, some extra features are computed here.
