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

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

— 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

ITU

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 mac hine’s

jobs that it stores.

Compatibility — The term “compatible” describes the ability of separate things to function

together. Your Muratec fax machine features

ITU

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,

and

MSE
