	User's Guide for ZyXEL Omni 56K USB Modem
Switched 56	Digital service at 56 Kbps provided by local telephone companies and long distance
	carriers. Similar to ISDN, Switched 56 traffic can travel over the same physical
	infrastructure that supports ISDN. Switched 56, however, is an older technology with
	decreasing significance.
Symbol Speed	Speed at which a signaling unit is transferred. In modern modem modulation, a signaling
	unit is no longer a single bit. Thus, the bit speed is different from the symbol speed.
Synchronous	In synchronous transfer, a dedicated control signal line transmits a clock signal that paces
	the transmitted data. In high speed connections, the transfer between two modems is always
	synchronous, even if the DCE to DTE connection is asynchronous.
T.30	A standard for fax transfers.
TAE6	A standard for a telephone wall outlet used in some countries, particularly in Germany.
Telnet	Telnet is the login and terminal emulation protocol common on the Internet and in UNIX
	environments. It operates over TCP/IP networks. Its primary function is to allow users to
	log into remote host systems.
Tempest	Illegal interception of data from computers and video signals.
ter	Old French word for three.
Terminal	A device that allows you to send commands to a computer somewhere else. At a minimum,
	this usually means a keyboard and a display screen and some simple circuitry.
Terminal	A computer running terminal software is used as terminal equipment in modem
Equipment	connections.
Terminal	Software that pretends to be (emulates) a physical terminal and allows you to type
Software	commands to a computer somewhere else.
Token	A token is a re-encoding of information in less bits; basically an abbreviation.
Transfer Mode	Data can be transferred either synchronously or asynchronously.
Transfer Rate	The speed at which the data bits are effectively transferred.
UART	Universal Asynchronous Receiver and Transmitter; a special IC chip which controls the
	serial port. Different models are available for PCs. Models with an internal buffer usually
	allow higher transfer rates.
UNIX	A widely used operating system in large networks.
URL	(Uniform Resource Locator) URL is an object on the Internet or an intranet that resides on
	a host system. Objects include directories and an assortment of file types, including text
	files, graphics, video, and audio. A URL is the address of an object that is normally typed
	in the Address field of a Web browser. The URL is basically a pointer to the location of an
	object.
V.	The ITU-TSS V. – standards describe data transfer via telephone lines.
WAN	Wide Area Networks link geographically dispersed offices in other cities or around the
	globe. Just about any long-distance communication medium can serve as a WAN link,
	including switched and permanent telephone circuits, terrestrial radio systems, and satellite
	systems.
Warez	A term that describes Pirated Software on the Internet. Warez include cracked games or
