Prestige 304 Broadband Sharing Gateway with 4-Port Switch

 

 

 

 

 

 

 

 

Two wires are twisted together to form a pair; the pair form a balanced circuit. The

 

 

 

 

twisting prevents interference problems, STP provides protection against external

 

 

 

 

crosstalk.

 

 

 

 

 

 

 

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

 

 

 

 

commonly used Ethernet cable.

 

 

 

 

 

 

 

SUA

 

Single User Account. Your system'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 device

 

 

 

 

will compute the subnet mask automatically based on the IP Address that you entered.

 

 

 

 

You do not need to change the computer subnet mask unless you are instructed to do

 

 

 

 

so.

 

 

 

 

 

 

 

T

 

 

 

 

 

 

 

 

 

TCP

 

Transmission Control Protocol is a connection-oriented transport service that ensures

 

 

 

 

the reliability of message delivery. It verifies that messages and data were received.

 

 

 

 

 

 

 

Terminal

 

A device that allows you to send commands to a computer somewhere else. At a

 

 

 

 

minimum, this usually means a keyboard, 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.

 

 

 

 

 

 

 

U

 

 

 

 

 

 

 

 

 

UDP

 

User Datagram Protocol. DP is a connectionless transport service that dispenses with

 

 

 

 

the reliability services provided by TCP. UDP gives applications a direct interface with

 

 

 

 

the Internet Protocol (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. Usually used on workstations and
