The main difference between this setup and that described in section "Mobile-to-fixed Audio Quality Measurement with CallGenerator" is that the fixed CallGenerator is replaced by a Mobile Receiving Unit, MRU, as recipient of the AQM calls. This is the M2M DL option in the AQM Measurement activity of the Service Control script (see section " AQM Measurement").

Another important difference is that only downlink AQM scores are obtained with this method; the MRU does not have an AQM module.
