81. AQM for CS Voice with AQM Modules

This AQM method measures audio quality during CS voice calls, with dedicated hardware units called AQM modules computing the AQM scores.

The voice calls are mobile-originated, and they may be received:

by a stationary component known as CallGenerator, connected to the fixed telephone network (section "Mobile-to-fixed Audio Quality Measurement with CallGenerator"), or

by a Mobile Receiving Unit (MRU) housed in a mobile phone (section "Mobile-to-mobile Audio Quality Measurement with MRU").

Further technical information about these methods of audio quality measurement is found in the document "AQM in TEMS Products", which is included in the TEMS Investigation documentation package. A separate MRU User's Manual is also available.

Please note that POLQA is not available with these configurations.
