DTMF (Dual Tone Multi-Frequency) signaling is required for
access to special network services offered by some telephone
companies. This system allows the proprietary telephone user to
send DTMF signals to the line during an established call.
• If the dial type of the line is assigned to DTMF, Tone Through mode is
established automatically after the dialing sequence is finished and the
call is established.
• If the dial type of the line is assigned to dial pulse, Tone Through mode
is established after the dialing sequence is finished and the " #"
buttons are pressed (Pulse to Tone Conversion).
• This function also applies to extension and conference calls.
No programming required.
