Telenetics 326X V.34, V.34-SDC, V.32bis Series manual Eia

DTMF	Dual Tone Multi-Frequency. A signaling method used for push-button telephones that
	combines two output signals to create a unique tone for each of the 12 keys.
EBCDIC	Extended Binary Coded Decimal Interchange Code. A method of coding digital signals
	using eight bits to generate 256 different characters.
Echo	Reflection back to the sender of a transmitted signal (as heard on telephone circuits
	involving long distances, or poor transmission facilities).
EIA	Electronic Industries Association. The American electronics standards group.
EIA/TIA 232-D	The most commonly used computer/modem interface. An electrical standard for
	interconnecting data communications equipment (DCE) and data terminal equipment (DTE)
	established by EIA. (The pinout is the same as for EIA 232-C and is nearly equivalent to
	ITU V.24.)
EOT	End-of-transmission control character in character-oriented protocols (applied to BISYNC).
	Tells the receiver that all user data (text) has been sent.
ETX	End-of-text control character. Tells the receiver that the end of a message has been reached.
Exclusion key	Allows calls to be answered manually and transferred to the modem using an integral
telephone	exclusion key.
Fallback	Switching the data system to a lower transmission speed either for reduced traffic during
	off-peak hours or because of distortion in the telephone system.
Fall forward	Switching from a lower to a higher data rate.
Flow control	Controls data transfer between endpoints in a data network; line signals or flow control
	characters stop and start the flow of data.
Four-wire	A circuit containing two pairs of wires, one pair for each transmission direction.
Full-duplex	A signaling circuit that allows simultaneous 2-way transmission and reception.
Frame	A group of bits transmitted serially over a communications channel. The basic data
	transmission unit used with bit-oriented protocols.
Gain	The amount by which an amplifier (or power) increases the amplitude of a signal passing
	through it; often represented in dB.
Half-duplex	A circuit that allows alternating transmit and receive signals, but not both simultaneously.
HDLC	High-level data link control. ITU-specified, bit-oriented, data-link control protocol; any
	related control of data links by specified series of bits rather than by control characters.
Hexadecimal	Base 16 number system with digits ranging from 0 to F.
ITU. See CCITT	International Telecommunications Union. Formerly CCITT.
ITU -T	Telecommunication Standardization Sector of ITU.
ITU V.13	V.13 signaling allows your modem to communicate with non-Telenetics modems. This
	signaling operates when the modem is configured for synchronous mode.
ITU V.22 bis	2400 bps modem standard for use with dial and leased-line circuits.
