12.00 Tone Through (End to End
DTMF Signaling)
Description
During a call (extension, outside or doorphone),
this function allows the PITS telephone user to
send DTMF (touch tone) signals to the voice path
when a dial pad button is pressed.
Tone Through mode is established automatically
after the dialing sequence.
End-To-End DTMF Signaling permits the
extension user to access network services such
as OCC access which requires touch-tone
signals.
Only during a conversation with an outside party,
Tone Through mode can be canceled by pressing
the Tone Through Break button (Assignable
Feature Button).
