1. Configure the DECT tester (CMD60) as follows;
<Setting>
·
Test mode: FP
·
Mode: Normal
·
PMID: 0000
2. Execute the command "testmode".
3. Initiate connection from DECT tester.
4. Execute the command "hookoff".
5. Execute the command "openau".
6. Connect J1 (Telephone Socket) to Tel-simulator which is connected with 600
Ω
.
7. Set line voltage to 48V and line current to 40mA.
8. Input audio signal (30mVrms/1kHz tone) to DECT tester.
<DECT tester setting>
·
Scramble: On
·
AF Gen to ADPCM: On
·
AF Meter Input: AF Voltm
·
AF Gen Frequency: 1000Hz
·
AF Gen Level: 30mVrms
9. Confirm hearing tone: 300mVrms ± 50mVrms.
10. Adjust audio level if required. (Make sure current value using "getspkrgain".
And then execute the command "setspkrgain xx", where xx is the value.)
11. Confirm that the audio distortion at 600R of Tel-simulator is < 5 %.
