ZyXEL Communications 782R manual 158

	Prestige 782R G.SHDSL Router
Straight Through	A cable that wires a pin to its equivalent pin. This cable connects two dissimilar
Ethernet Cable	devices, for example, a data terminal equipment (DTE) device and a data
	communications equipment (DCE) device. A straight through Ethernet cable is the
	most common cable used.
SUA	Single User Account. The Prestige's SUA feature allows multiple user Internet access
	for the cost of a single ISP account. See also NAT.
Subnet Mask	The subnet mask specifies the network number portion of an IP address. Your
	Prestige will compute the subnet mask automatically based on the IP Address that you
	entered. You do not need to change the subnet mask computed by the Prestige
	unless you are instructed to do otherwise.
Syslog	An abbreviated form of System Log. Using the UNIX syslog facility, the Prestige
	records (logs) phone calls or creates a CDR (Call Detail Record). Syslog is an
	administrative tool that assists accounting and is configurable via the SMT.
TCP	Transmission Control Protocol handles flow control, packet recovery, IP providing
	basic addressing and packet-forwarding services.
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.
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	Software that pretends to be (emulates) a physical terminal and allows you to type
Software	commands to a computer somewhere else.
TFTP	Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP (File
	Transfer Protocol), but it is scaled back in functionality so that it requires fewer
	resources to run. TFTP uses the UDP (User Datagram Protocol) rather than TCP
	(Transmission Control Protocol).
Twisted Pair	Two insulated wires, usually copper, twisted together and often bound into a common
	sheath to form multi-pair cables. In ISDN, the cables are the basic path between a
	subscriber's terminal or telephone and the PBX or the central office.
UDP	User Datagram Protocol is a connectionless transport service that dispenses with the
	reliability services provided by TCP. UDP gives applications a direct interface with IP
	and the ability to address a particular application process running on a host via a port
	number without setting up a connection session.
UNIX	A widely-used operating system in large networks.
URL	A Uniform Resource Locator is an object on the Internet or an intranet that resides on
