Glossary
This glossary contains terms you may encounter when discussing or reading about fax
machines. Please use these definitions for reference only. A list of definitions can also be found
on the Muratec website at www.muratec.com.
24-hour format — Also called military format. A format for keeping time that does not use
a.m. or p.m. to distinguish between morning and afternoon. In the 24-hour format, one o’clock in
the morning marks 1:00, noon marks 12:00 and midnight marks 24:00. To calculate the 24-hour
format, add 12 hours to all times after noon.
For example, 1:30 p.m. would be 13:30 in the 24-hour format; 10:45 p.m. would be 22:45 in the
24-hour format. And 11:15 a.m. would be 11:15 in the 24-hour format.
A3, A4, B4 — Standard stationery sizes defined by the International Standards Organization,
an agency of the United Nations. See also Paper sizes.
ADF — Automatic document feeder. See document feeder.
Alternate number — The number your machine dials after all attempts to the regular number
fails. The user programs this alternate number, if so desired.
Answering machine — See
TAD
.
Autodialing — Enables user to store preprogrammed telephone numbers in the unit’s memory.
Storage capability varies from unit to unit.
Automatic fallback — The ability of a fax machine to slow down (“fall back”), when communi-
cating with another fax which is communicating at a slower rate.
Automatic reduction — Many Muratec fax machines will automatically reduce the size of
documents being transmitted to accommodate the effective printing width of the receiving unit.
For example, this allows a fax machine with a 10″ scanning width to send an image 10″ wide to
a unit with an 8.5″ print width. The receiving fax machine will receive a reduced-size printout of
the complete image.
Bit — The smallest unit of information in a computer. Some Muratec fax machines, which are
actually computers “dedicated” to telecommunications, allow users to change bits of information
to provide or cancel features through software settings.
Bits per second — See bps.
Black density — Also called black coverage. The amount of non-white area on a page. For
example, most regular office correspondence has a black density well under 10%, due to the
presence of margins, spaces between words, spaces between lines and paragraphs and even
spaces within letters. However, drawings and photographs have a much higher black density,
sometimes approaching 100%. The higher a page’s black density, the more slowly a fax machine
sends it.
Broadcast — A fax transmission in which a single document is sent to more than one location.
bps — Bits per second. Used to express the speed of transmission of data. Because fax transmis-
sion treats a document as a graphic image rather than as a series of alphabetic and numeric
characters, bps does not correspond to the number of characters transmitted per second.
Byte — A group of digital elements, usually sent as eight bits to the byte.
Call reserve — Also called call request. An
ITU
-
T
standard fax feature which allows a user to
request voice communication prior to, during or after transmission.
Call-waiting service — An optional telephone company service that alerts you to another
incoming call when the phone is already in use. Call-waiting signals often cause interruption of
fax transmission or reception.
Caller
ID
— Optional service provided by your local telephone company that allows you to see a
display of the number (phone or fax) that is calling.
CCITT
— See

.
CCD
,
CIS
— Charged coupled device, contact image sensor. Two types of scanning mechanisms
used in some Muratec fax machines. The
CCD
“reads” fluorescent light bouncing off a document.
The
CIS
uses a flat bar of light-emitting diodes (
LED
s).
Command queue — The “list” your machine keeps of all its pending commands.
Command number — The number your machine gives to each “job” it is programmed to com-
plete. You must know the command number in order to cancel or change any of the machine’s
jobs that it stores.
Compatibility — The term “compatible” describes the ability of separate things to function
together. Your Muratec fax machine features
ITU
-
T
Group 3 compatibility, the modern standard
for worldwide communication.
Confidential transmission — See SecureMail.
Confirmation report — See
RCR
and
TCR
.
Continuous polling — See Polling.
Copy mode — Allows your fax machine to be used as a convenience copier.
Cover page (automatic) — A small, user-created message; can be the first page of every
transmission.
Database polling — See Polling.
Data compression — Used in digital fax machines to speed transmission. See also Digital fax,
MH
and
MSE
