5.2.5 Auto-Level Assist

The Auto-Level Assist Wizard provides an automatic method for determining optimal downlink

and uplink volume for Voice Quality Tasks running on mobiles connected via the analog audio

interface. The Auto-Level Assist Wizard has no bearing on Call Performance Tasks or on Voice

Quality Tasks using a Bluetooth connection. The Auto-Level Assist procedure bypasses the need

for manual adjustments in determining the optimal input level (downlink volume) and output level

(uplink volume) for testing.

Before beginning the Auto-Level Assist process, please take note of these guidelines recommended

by and followed by Spirent staff:

 Confirm that the test mobile is in a good coverage area.

 Confirm the presence of a high-speed internet connection required for auto-calibration with

the Auto-Level Assist Wizard.

To run the Auto-Level Assist Wizard:

 From the Test Setup tab, select the Auto Level Assist button found under any Voice Quality

task using the Analog Audio Interface (see Section 5.2.3 to select the Channel Audio

Interface).

 Confirm that the Audio Server settings are correct using the Validate Settings button. It is

not possible to continue beyond this screen until the Audio Server settings have been

validated.

 Click Next to continue.

 Confirm that the Handset Phone # and Audio Server # are correct for all channels to be

optimized. Use the Connection Assistant for the highest accuracy when entering the

phone numbers (see Section 5.2.2 for more information on the Connection Assistant).
