offices); this is often called the local loop. The PSTN is a circuit-switched system, meaning that an end-to-end private circuit is established between caller and callee.

Permanent Virtual Circuit. A PVC is a logical point-to-point circuit between customer sites. PVCs are low-delay circuits because routing decisions do not need to be made along the way. Permanent means that the circuit is preprogrammed by the carrier as a path through the network. It does not need to be set up or torn down for each session.

An RFC (Request for Comments) is an Internet formal document or standard that is the result of committee drafting and subsequent review by interested parties. Some RFCs are informational in nature. Of those that are intended to become Internet standards, the final version of the RFC becomes the standard and no further comments or changes are permitted. Change can occur, however, through subsequent RFCs.

Routing Information Protocol is an interior or intra-domain routing protocol that uses distance-vector routing algorithms. RIP is used on the Internet and is common in the NetWare environment as a method for exchanging routing information between routers.

In telephony, a splitter, sometimes called a “plain old telephone service splitter" is a device that divides a telephone signal into two or more signals, each carrying a selected frequency range, and can also reassemble signals from multiple signal sources into a single signal

Shielded Twisted-Pair cable consists of copper-core wires surrounded by an insulator. 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.

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 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.

 

 

 

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.

 

 

 

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, display screen and some simple circuitry.

 

 

 

Terminal

 

Software that pretends to be (emulates) a physical terminal and allows you to type
