D:AUDIO TESTS (ITU standards only)

As the second audio line input could not be activated on either unit, it was not possible to carry out tests 2 or 3.

Test 1 was carried out with test signals inserted into the Headset Microphone input with the Echo Canceller set to OFF. The audio output level was then adjusted by the system volume control.

Test 1: Frequency response (-3dB)

(Insert a -30dB (Mic Level) signal at the local site, measure at remote site)

G.722

G.728

G.7111

5.6KHz

3.5KHz

3.3KHz

Test 2: Headroom (measured on G722 connection)

(Insert increasing amplitude 1 KHz tone at local site, monitor for overload distortion at remote site)

Overload occurs at:

Not Measured

Test 3: Audio Level

(Insert -6dBm 1KHz tone at local site, monitor received level at remote site)

Remote site signal measures:

Not Measured

 

Test 4: Echo Cancellation

 

 

Setup

The echo canceller is fully automatic in operation.

Quality of double talk

Not Tested

Poor

Comments: In tests with the JVCS Management Centre the received audio level was measured as peaking between 0 and +4dBm. Tests were carried out with AGC Off and the microphone level was adjusted to achieve the correct received level at the management centre. With AGC On, when the user was not speaking there was a high background noise level. AGC status is selected from the Controls Menu.

*While the Echo Cancellation was acceptable there was a noticeable residual echo at times.
