Glossary

This glossary contains terms and words you may encounter when discussing or reading about fax machines and fax communications. Please use these definitions for reference only.

A4, B4, A3 — Standard stationery sizes defined by the International Standards Organization, an agency of the United Nations. See also Paper sizes.

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 communicating 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″ scan- ning 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. The word “bit” is a contraction of the two words “binary digit.”

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 pho- tographs have a much higher black density, sometimes approaching 100%. The higher a page’s black density, the more slowly a fax machine sends 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 char- acters 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.

Just in case …

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 ITU-T.

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 (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 worldwide communication.

Confidential transmission — See SecureMail.

Confirmation report — See TCR.

Copy mode — Allows your fax machine to be used as a convenience copier.

Cover page (automatic) — A small, user-created message which can be the first page of every transmission.

Data compression — Used in digital fax machines to speed transmission. See also Digital fax, MH and MSE, SMSE.

Default — The setting your machine will always refer to if no other action has been programmed. For example, you can set the default for this machine to send a fax by using its memory. If you set this action as the default, that’s how your machine will always send a fax, until you tell it to do differently.

Delayed command — Transmission or polling operation set by the user to occur later, automatically, at a predetermined time. Great for reducing costs by making fax calls during times when telephone costs are lowest, such as late at night or on weekends.

Digital — Using the binary system (which uses a combination of 0s or 1s) to describe everything, so that 0 means off and 1 means on; digital fax machines con- vert the graphic image of your document into a series of zeros and ones by using the binary system of transmission to encode black and white occurrences. This increases transmission speed by passing over white spaces. See also White-line skip.
