[1913 Webster]Telegraph \Tel"e*graph\, n. [Gr. ? far, far off (cf. Lith. toli)
+ -graph: cf. F. t['e]l['e]graphe. See Graphic.]
An apparatus, or a process, for communicating intelligence
rapidly between distant points, especially by means of
preconcerted visible or audible signals representing words or
ideas, or by means of words and signs, transmitted by
electrical action.
[1913 Webster]
Note: The instruments used are classed as indicator,
type-printing, symbol-printing, or chemical-printing
telegraphs, according as the intelligence is given by
the movements of a pointer or indicator, as in Cooke &
Wheatstone's (the form commonly used in England), or by
impressing, on a fillet of paper, letters from types,
as in House's and Hughe's, or dots and marks from a
sharp point moved by a magnet, as in Morse's, or
symbols produced by electro-chemical action, as in
Bain's. In the offices in the United States the
recording instrument is now little used, the receiving
operator reading by ear the combinations of long and
short intervals of sound produced by the armature of an
electro-magnet as it is put in motion by the opening
and breaking of the circuit, which motion, in
registering instruments, traces upon a ribbon of paper
the lines and dots used to represent the letters of the
alphabet. See Illustration in Appendix, and {Morse
code}.
[1913 Webster]
Note: In 1837, Samuel F. B. Morse, an American artist,
devised a working electric telegraph, based on a rough
knowledge of electrical circuits, electromagnetic
induction coils, and a scheme to encode alphabetic
letters. He and his collaborators and backers
campaigned for years before persuading the federal
government to fund a demonstration. Finally, on May 24,
1844, they sent the first official long-distance
telegraphic message in Morse code, "What hath God
wrought," through a copper wire strung between
Washington, D.C., to Baltimore, Maryland. The phrase
was taken from the Bible, Numbers 23:23. It had been
suggested to Morse by Annie Ellworth, the young
daughter of a friend. --Library of Congress, American
Memories series

acoustic coupler
(foldoc) | acoustic coupler
A device used to connect a modem
to a telephone line via an ordinary handset. The acoustic
coupler converts electrical signals from the modem to sound
via a loudspeaker, against which the mouthpiece of a telephone
handset is placed. The earpiece is placed against a
microphone which converts sound to electrical signals which
return to the modem. The handset is inserted into a
sound-proof box containing the louspeaker and microphone to
avoid interference from ambient noise.
Acousitic couplers are now rarely used since most modems have
a direct electrical connection to the telephone line. This
avoids the signal degradation caused by conversion to and from
audio. Direct connection is not always possible, and was
actually illegal in the United Kingdom before {British
Telecom} was privatised. BT's predecessor, the General Post
Office, did not allow subscribers to connect their own
equipment to the telephone line.

and a MDCT based transformation encoder.
