sine waves, that can be heard by human
ears.
Digitize
To translate into a digital form. For
example, optical scanners digitize images
by translating them into bit maps. It is
also possible to digitize sound, video, and
any type of movement. In all these cases,
digitization is performed by sampling at
discrete intervals. To digitize sound, for
example, a device measures a sound
wave’s amplitude many times per second.
These numeric values can then be
recorded digitally.
Distinctive Ring
The ability to have more than one
telephone number that callers can dial to
reach the same telephone line. Each
Distinctive Ring number has a distinctive
ring cadence or ring sequence.
TalkSwitch recognizes Distinctive Ring 1
as 2 short rings. Distinctive Ring 2 is
identified as 3 short rings. (Distinctive
Ring is also referred to as: Ident-A-Ring,
Ident-A-Call, Ring Master, Teen Service,
Double Number, Personal Ringing, Ring
Plus, Smart Ring Service, Special Ring or
Customized Ringing).
Driver
A program that controls a device. Every
device, whether it is a printer, disk drive,
or keyboard, must have a driver program.
A driver acts like a translator between the
device and programs that use the device.
DTMF
Dual Tone Multi-Frequency. The system
used by touchtone telephones. DTMF
assigns a specific frequency, or tone, to
each key so that it can easily be identified
by a microprocessor.
Extension (Local)
A Local Extension is any telephone or
analog device (answering machine, fax,
etc.) that is plugged into one of the
‘Extensions’ jacks located on the back
panel of your TalkSwitch.
Extension (Remote)

any telephone number, in any location.
FCC
Federal Communications Commission.
The FCC is the United States federal
regulatory agency responsible for the
regulation of interstate and international
communications by radio, television,
wire, satellite and cable.
Firmware
Firmware is a combination of software
and hardware. More precisely, it is
software (programs or data) that has
been written onto hardware
(micro-chips). Micro-chips (ROMs,
PROMs and EPROMs) that have data or
programs recorded on them are called
firmware.
Flash button
A button on your telephone. Pressing the
Flash button has the same effect as press-
ing the Link button or depressing and
releasing the ‘hang up’ (switch) hook on
a telephone. All of these actions will send
a signal to TalkSwitch to put calls on or
off hold.
Home phone
A home phone is any telephone using the
same telephone line as one of
TalkSwitch’s Lines, but is not plugged
directly into the back of TalkSwitch as an
extension.
Icon
A small picture that represents a
program, action or feature in the config-
uration software. When you click on an
icon, that program, action or
feature is activated.
