DTMF: 0/1/2/3/4/5/6/7/8/9/A/B/C/D//#
- DTMF Individually
Checks the tone output for one of the 16 key numbers set on the LCD.
- Dial Pulse Send
Unplug the modular connector of the telephone line before performing this test.
Otherwise, a call will be made to the relevant number.
-DP10 Individually
Checks the 10PPS pulse output for one of the 10 key numbers set on the LCD.
-DP20 Individually
Checks the 20PPS pulse output for one of the 10 key numbers set on the LCD.
- Ring Back Tone
Checks the tone output for the ring back tone.
- Data Send
Checks the modem output for each of the transmission rates in compliance with ITU-T recommendations.
Below are the data sending patterns:
All 0/All 1/0101010101/0000100001/11101110
