137 Glossary
Digit
Any whole number from 0 to 9. The
numbers on your telephone keypad can
also be referred to as digits.
Digital
Digital devices (phones, answering
machines, etc.) convert analog sine
waves into digital signals (a combination
of zeroes and ones) for storage and/or
transmission over digital lines.The digital
signal is then converted back to analog
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.
DSP
Digital Signal Processing. Refers to
manipulating analog information, such
as sound or video that has been
converted into a digital form.
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.
EEPROM
TalkSwitch's feature settings
(configuration) are stored in EEPROM
which is a form of non-volatile memory.
This means that the feature settings
(configurations) remain in TalkSwitch's
memory despite interruptions in
TalkSwitch's power supply.

Command Set that is specific to
TalkSwitch. The extended
command is indicated by an '!'
(e.g. AT!|TS).

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)
A call forwarding number that can be
any telephone number, in any location.
