Tone Length DTMF (Dual Tone Multi-Frequency) is the
system used by touch tone phones under
which a specific frequency or tone is
assigned to each key. There is a standard
length for these tones. However, some
voice mail systems require a shorter or
longer than normal length tone.
This field allows you to set the AirCard to
use a shorter or longer tone for systems
that require it.
The recommendation is to select normal
unless your service provider indicates that
a different tone length is required.
Level This field allows you to adjust the volume of
the beep that occurs when you click
buttons on the dial pad.
From the drop-down list, select a number.
A higher number will give a louder beep.
Mute When DTMF mute is enabled, there is no
audible tone while the AirCard dials.
Use the check box to enable and disable
the feature. (The feature is enabled when
checked.)
Minute Alert This field allows you to enable and disable
the Minute Alert feature.
When enabled, the AirCard beeps at one
minute intervals while you are on voice
calls. This allows you to keep track of the
duration of your call.
Use the check box to enable and disable
the feature. (The feature is enabled when
checked.)
