18 DTMF
The transceiver supports DTMF (Dual Tone Multiple
Frequency) as a signaling method.
DTMF uses 2 different tones simultaneously. DTMF can
be used to make a call with a PTT ID or an individual call,
transmit the telephone number while connecting to the
phone line, and remotely control the transceiver.
DTMF signaling uses 2 different frequencies (a high
frequency and a low frequency) and consists of DTMF 0
to 9, A to D, *and # Code.
