Receive Audio Check
and Adjustment
1.
Configure the DECT tester (CMD60) as follows;
<Setting>
·
Test mode: FP
·
Mode: Normal
·
PMID: 00000
2.
Execute the command “testmode”.
3.
Initiate connection from DECT tester.
4.
Execute the command “hookoff”.
5.
Execute the command “openau”.
6.
Connect J2 (Telephone Socket) to Tel-simulator which is connected with 600
Ω
.
7.
Set line voltage to 48 V and line current to 40 mA.
8.
Connect DECT tester to Tel-simulator.
9.
Input audio signal (200 mVrms/1 kHz tone) to Tel-simulator.
<DECT tester setting>
·
Scramble: On
·
AF Gen. to ADPCM: Off
·
AF Meter Input: ADPCM
·
AF Gen. Frequency: 1000 Hz
·
AF Gen. Level: 200 mVrms
10. Confirm hearing tone: 380 mVrms ± 100 mVrms
11. Adjust audio level if required. (Make sure current value using “getmicgain”. And
then execute the command “setmicgain xx”, where xx is the value.)
12. Confirm that the B-field audio distortion with DECT tester is < 5 %.
