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.

A4, B4, A3

Standard stationery sizes defined by the International Standards Organization, an agency of the United Nations. See also 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 e and o). 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-Tstandard 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-T.

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 (LEDs).

Compatibility

The term “compatible” describes the ability of separate things to function together. Your Muratec fax machine features ITU-TGroup 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, MH, and

MSE, SMSE.
