1.3 System Features
Dial Type Selection
Description
Used to select the desired dialling mode for each CO line regardless of originating call
extension (rotary or tone).
There are two dialling modes available:
DTMF (Dual Tone Multi-Frequency) Mode
The dialling signal from an extension, either tone or rotary, is converted to tone dialling.
DTMF signals are transmitted to the CO line.
Pulse Dial (Rotary) Mode
The dialling signal from an extension, either tone or rotary, is converted to rotary dialling.
Rotary pulses are transmitted to the CO line.
Conditions
• Pulse to Tone Conversion
The extension user can convert the pre-assigned rotary dialling mode to DTMF mode
temporarily. DTMF mode cannot be changed to rotary.
• DISA
Either DTMF or rotary dialling can be assigned for the DISA (Direct Inward System
Access) outgoing line. With DISA, Pulse to Tone Conversion is not possible.
• If a line is assigned Pulse Dial mode, select an appropriate pulse speed, pulse break ratio,
and inter-digit pause for the line, if necessary. If a line is assigned DTMF, select an
appropriate DTMF duration for the line in "Card Properties" screen, if necessary. Please
refer to "Card Type" in Section "1.2 Slot Assignment" of the Programming Guide for
further information.
