Straight Through
Ethernet Cable
A cable that wires a pin to its equivalent pin. This cable connects two dissimilar
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
Software that pretends to be (emulates) a physical terminal and allows you to type
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
