80. AQM for CS Voice with ACU TerraTec

This AQM method measures audio quality during CS voice calls. Up to four mobile devices, which call each other in pairs, are connected to an Audio Capturing Unit (ACU; TerraTec box) which relays the audio to the PC.1 Please note that this AQM configuration is not available for purchase with TEMS Investigation 23.3: the TerraTec ACU is no longer for sale. TEMS Investigation 23.3 does however still support the use of this AQM method with previously purchased components.

This configuration is referred to by the M2M DL + UL option in the AQM Measurement activity of the Service Control script (see section " AQM Measurement").
