Glossary

When you order Internet service, your provider will give you a greatdeal of information. Definitions of common configuration terms areavailable below. Please note that terminology used by various remotenetworks may vary.

ADSL(Asymmetric Digital Subscriber Line) - Currently the mostcommon DSL technology available that provides asymmetrical

bandwidth over a single copper wire pair (over your regular telephoneline). The downstream bandwidth from the network to the subscriberis greater than the upstream bandwidth from the subscriber to thenetwork. ADSL speeds typically run from 1.5 Mbps to 8 Mbpsdownstream and 64 Kbps to 640 Kbps upstream.

Bandwidth - The amount of data that can be transmitted by thenetwork information highway, used as an indication for speed ofdata transmission. An Ethernet link is capable of moving 10 million

bits of data per second.

Bit - The term used to refer to a single unit of data in digital datacommunications. It takes 8 bits to make 1 byte, which is a unit ofmeasurement for computer data.

Bps(Bits per second) - Refers to the unit of measurement used fordata transmission speeds over a data communication link, e.g. ADSLruns at 6 Mbps (MegaBits per second).

Bridge - A hardware device that passes packets between multiplenetwork segments using the same networking protocol to connect thedifferent network segments. A DSL modem is a bridge that passesDSL from one network segment to another. Bridge operates at thehardware layer and has no routing capabilities.

Broadband - Any high-bandwidth (see also Bandwidth) datacommunication technology that runs at speeds of 200 Kbps or moreand allows combined transmission of voice, data, and video over asingle physical connection. Broadband is in contrast to narrowbandsuch as traditional 56K analog modem. DSL, Cable, wireless, andsatellite technology are all different types of broadband technology.

Byte - A unit of data equaling to 8 bits (1 Byte = 8 bits).

DHCP(Dynamic Host Configuration Protocol) - An Internetprotocol that allows the DHCP server to dynamically assign IPaddresses to any client workstation (any device connected to yourLAN, such as a PC) for a set period of time and then sends them backso that they can be reassigned to other workstations. This feature

saves the ISP and Network Managers from having to manuallyconfigure IP addresses for each PC on the LAN.

DSL (Digi tal Subscriber Line) - A new kind of digitized datacommunication technology that delivers high-speed, two-way Internetaccess over the traditional copper wire telephone line. DSLtechnology allows the user to share their phone line with their DSLline, providing an always-on Internet connection that runs at speedsfrom 1 Mbps to 52 Mbps depending on the distance between the

customer site and the CO. There are many type of DSLs called xDSL,and the most commonly available DSL line is the ADSL (SeeADSL),which supports up to 6 - 8Mbps downstream. Other types of DSLinclude SDSL, IDSL, HDSL, VDSL, RADSL, etc.

DSL technology can be accessed by connecting a DSL modem at thecustomer premise to the telephone line and computer. At the end ofthe line, DSL-enabling equipment at the CO, such as a DSLAM,

aggregates or consolidates all the customer DSL lines and routes thedata traffic onto a backbone network for distribution to the ISP orcorporate networks.

DNS (Domain Name System) - A mechanism that translates hostdomain names into its numeric IP Address andvice-versa. A domainname is an easy-to-remember nickname for numerical IP addressesrequired by a computer, such as [email protected].

Encapsulation - The encapsulating or enclosing data within aparticular IP header. Sometimes the entire frame from one network isplaced in the header used by the data link layer protocol of anothernetwork.

Encryption - A specific algorithm used to encrypt or encode the dataso that it becomes unreadable to unauthorized users that do not knowthe decryption key. A good example of encryption technology is WEP(Wired Equivalent Private).

Ethernet - Most popular LAN (Local Area Network) technology thatuses CSMA/CD (Collision Detection) and transfers data betweenworkstations over a variety of cable types at 10Mbps, also called10BaseT. Most Ethernet LANs use twisted pair 10BaseT cables andsupport both Ethernet as well as Fast Ethernet at 100Mbps(100BaseT).

Glossary A-3

Firewall - A security device (either hardware, software, or acombination of both) that selectively blocks out or filters unwanted IPtraffic from a public network. Firewall allows the private LAN networkto be invisible to the public network outside, preventing intrusion fromunauthorized users.

Hub - A hardware device that repeats all data traffic to all CPE(Customer Premises Equipment) ports. A hub functions as the centerof a LAN and all other network devices on the LAN, including PCs,printers, DSL modem or Gateways, are connected to the hub throughcabling.

Internet - A massive worldwide network of computer networksinterconnecting thousands of computers and networks around the

world and readily accessible from any computer with a modem orrouter connection and the corresponding software.

IP (Internet Protocol) - A protocol standard for the Internet. A kind ofInternet software that keeps track of all the addresses on the Internetfor different nodes, forwards outgoing IP traffic, and recognizesincoming IP traffic.

IP Address - numeric address assigned to each machine on the

Internet. Consists of four sets of one, two, or three octal digitsseparated by periods.

ISP (Internet Service Provider) - The telecommunication companythat provides Internet service for the subscriber. The ISP can be atelephone company, a CLEC or ILEC, or any other company thatprovides Internet access to the end user such as AOL, Earthlink orMSN.

LAN (Local Area Network) - A collection of privately owned,interconnected computers within a confined service area.

PPPoE (Point to Point Protocol over Ethernet) - It is a protocol thatallows a computer to access the Internet using a dial-up phone lineand a high-speed modem or router. Relying on two widely acceptedstandards, Ethernet and point to point protocol (PPP), it makes highspeed access easier to use for end consumers, and more seamlessto integrate into the existing infrastructure for carriers and ISPs.

Virtual Path Identif ier - A virtual path is a semi-permanentconnection between endpoints in an ATM network and may supportone or more virtual channels. In Private Virtual Circuit (PVC) mode,the Virtual Path (VP), which is a header subfield, is assignedmanually when NDS is used. Different VP values allow the endpointsto discriminate between different virtual connections and ATM nodes.
