How a Fax Works
Facsimile is a system of sending printed or other
graphic information from one location to another by
producing a copy or “facsimile” of that information
d the remote location. A fax unit transmits audio
ones over the same telephone lines you use for
lerson-to-person conversation.
The facsimile process involves three basic steps:
1.
2.
Reading and converting the document into
electronic signals (audio tones).
Sending, or transmitting, the signals through a
telephone system, to another fax unit.
3. Converting the received signals into a “facsimile”
of the transmitted document.
This is a simplified explanation of the actual
facsimile process. Although all fax units operate by
this same basic process, specific operating
procedures differ from unit to unit.
About Facsimile Compatibility
The
CCITT
(Consultative Committee for
International Telephone and Telegraph), which sets
worldwide standards for data communication,
classifies facsimile devices into three groups. The
grouping is based on how a fax unit sends
information, in what form, and at which speed.
To simplify, you can think of fax units as being
grouped by speed: Group 1 includes 6 minute units,
Group 2 includes 3 minute units, and Group 3
includes sub-minute units. These speeds refer to
the amount of time it takes a fax unit to send or
receive a standard business letter over the
telephone lines.
Your facsimile is compatible with
CCITT
G3 mode
units.
