Glossary

This glossary contains terms and words you may encounter when discussing or

reading about fax machines and fax communication. Please use these definitions

for reference only. Of course, all information is subject to change without notice.

Standard stationery sizes defined by the International Standards Organization, an

Paper sizes

Autodialing

Enables users to store pre-programmed telephone numbers in the unit’s memory.

Storage capability varies from unit to unit.

Automatic fallback

The ability of a fax machine, when communicating with another fax which is

communicating at a slower rate, to slow down (“fall back”) to the other unit’s

speed.

Automatic reduction

Many Muratec fax machines will automatically reduce documents being

transmitted to accommodate the effective printing width of the receiving unit. This

allows, for example, 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. Contraction of the term

binary

digit.

Some Muratec fax machines, which are themselves 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 under 10%, due to the

presence of margins, spaces between words, spaces between lines and paragraphs

and even spaces within letters (such as

and

). 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 can send it.

bps

Bits per second. Used to express the speed of transmission of data. Because fax

transmission 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 identifies when another party is

calling while one is already on the phone. Call-waiting signals often cause

interruption of fax transmission or reception.

CCITT

— See

ITU

CCD

CIS

Charged coupled device, contact image sensor. Two type 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).

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 world-wide fax communication.

Confidential transmission

— See

SecureMail

Confirmation report

— See

RCR

and

TCR

Copy mode

Lets one use a fax machine 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
