1.5 Making Call Features
44 Feature Guide
1.5.2.4 Dial Type Selection
Description
The dialling mode can be selected for each outside (CO) line through system programming ( Dial Mode
[401]) regardless of the originating extension (dependent on the contract with the telephone company).
Conditions
• Automatic Configuration for Outside (CO) Line Type
The dialling mode of connected outside (CO) lines is automatically assigned after restarting the PBX
using the System Clear Switch or through system programming ( System Data Clear [999]). No
system programming in Dial Mode [401] and Pulse Speed [402] is required unless the dialling mode of
the connected outside (CO) lines is Call Blocking. If your telephone company can receive both DTMF
and Pulse signals, the PBX selects an outside (CO) line type according to the following priority:
DTMF Pulse (High) Pulse (Low)
• Pulse to Tone Conversion
It is possible for an extension user to temporarily switch from Pulse mode to DTMF mode in order to
access special services such as computer-accessed long-distance calling or voice mail services. To
switch to DTMF mode, wait for a preprogrammed time period after the outside (CO) line is connected,
or press the " #" key. This feature functions only on outside (CO) lines set to "Pulse" or "Call Block"
mode ( Dial Mode [401]). DTMF mode cannot be changed to Pulse mode.
• The pulse rate for outside (CO) lines that have been set to "Pulse" or "Call Block" mode ( Pulse
Speed [402]) should be selected depending on your telephone company or a host PBX. There are 2
pulse rates: Low (10 pps) and High (20 pps).
• It is possible to assign the minimum duration of the DTMF signal sent to outside (CO) lines that have
been set to "DTMF" mode ( DTMF Time [210]).
• It is programmable whether DTMF dialling is sent to the telephone company when an extension user
redials after changing from Pulse mode to DTMF mode by pressing the " #" key ( Redialling after
Pulse to Tone Conversion [119]).

1.4.9 Changing the Dialling Mode (Pulse to Tone Conversion)
Mode Description
DTMF (Dual Tone Multi-
Frequency)
Numbers dialled by an extension user are transmitted to the outside (CO)
line using tones. If this PBX is installed behind an existing host PBX,
select this mode as necessary. If your telephone company or a host PBX
can receive both DTMF and Pulse signals but the contract specifies
DTMF lines, select this mode.
Pulse (Rotary) Numbers dialled by an extension user are transmitted to the outside (CO)
line using pulses.
Call Blocking If your telephone company or a host PBX can receive both DTMF and
Pulse signals but the contract specifies Pulse lines, select this mode.
When dialling with a touch-tone telephone, only Pulse signals will be sent
to the telephone company.
