Glossary 7

TCP/IP (Transmission Control Protocol/Internet Protocol): An open network standard that defines how devices from different manufacturers communicate with each other over one or more interconnected networks. TCP/IP protocols are the foundation of the Internet, a worldwide network of networks connecting businesses, governments, researchers, and educators.

telephone wall cable: 2-pair, 4-pair, or 8-pair, 22- or 24-gauge solid copper wire cable. Telephone wall cable is sometimes called telephone station cable or twisted-pair cable.

TFTP (Trivial File Transfer Protocol/Internet Protocol): A protocol used to transfer files between IP nodes. TFTP is often used to transfer firmware and configuration information from a UNIX computer acting as a TFTP server to an IP networking device, such as the Netopia ISDN Router.

thicknet: Industry jargon for 10Base-5 coaxial cable, the original Ethernet cabling.

thinnet: Industry jargon for 10Base-2 coaxial cable, which is thinner (smaller in diameter) than the original Ethernet cabling.

UDP (User Datagram Protocol): A TCP/IP protocol describing how packets reach applications in destination nodes.

V.90: A modem data transmission standard, also known as V.PCM, which merges the K56flex standard with the competing x2 standard. In September, 1998, the International Telecommunications Union is expected to ratify the unified standard, thereby allowing interoperability of modems and ISPs’ central site equipment, with appropriate firmware upgrades.

wall jack: A small hardware component used to tap into telephone wall cable. An RJ-11 wall jack usually has four pins; an RJ-45 wall jack usually has eight pins.

WAN (wide area network): A network that consists of nodes connected by long-distance transmission media, such as telephone lines. WANs can span a state, a country, or even the world.

WAN IP: In addition to being a router, the Netopia ISDN Router is also an IP address server. There are four

protocols it can use to distribute IP addresses over the WAN which include: DHCP, BOOTP, IPCP and MacIP. WAN IP is a feature for both the Small Office and Corporate Netopia ISDN Router models.

wiring closet: A central location where a building’s telephone and network wiring is connected. Multi-story buildings often have a main wiring closet in the basement and satellite wiring closets on each floor.

zone: An arbitrary subset of nodes within an AppleTalk internet. Creating multiple zones makes it easier for users to locate network services. The network administrator defines zones when he or she configures routers. Isolated networks have no zones. LocalTalk and EtherTalk Phase I networks may have no more than one zone each. EtherTalk Phase II and TokenTalk networks may have more than one zone each. Several networks of any AppleTalk type may share a zone name.
