Measuring Voice Quality

Part 1: Voice MOS Test (VMT) Office Utility 30

Part 2: Preparing Central Office for measurements 31

Part 3: Using Mobile Van and E6474A Sequencer for measurements 35

Part 4: Measurement results 38

The measurement of mobile network voice quality makes use

of two separate sets of equipment.

• Mobile van equipment.

• Central Office (CO) equipment.

Based on individual requirements, you need to configure

parameters on both systems using the Voice MOS Test (VMT)

Office Utility, Voice MOS Test and USB Audio Module control

applications prior to running measurements.

Once the system has been set up, the central office

sub- system will be in the slave/stand- by mode, and the van

sub- system will be the master controlling the execution of

measurements.

Prior to starting measurements, it is recommended that you

refer to the section, “Part 4: Measurement results” in this

chapter.
