Terminology
That part of a communications network which connects subscribers to their immediate service provider. It is contrasted with the core network.
A network in which the passive splitting point is replaced with an Optical Line Distribution unit which is a powered unit making it possible to have a higher bit rate on individual routes over longer distances than on a passive optical network.
ADSL standards for Asymmetrical Digital Subscriber Line. An ADSL Internet connection provides an always-on, high speed connection to the Internet using a standard copper telephone line. With ADSL you are able to use the Internet and telephone at the same time. It is labelled Assymetrical because your downloads speed is different to your upload speed.
The backhaul portion of the network comprises the intermediate links between the core, or backbone, of the network and the small sub networks at the "edge" of the entire hierarchical network. For example, while cell phones communicating with a single cell tower constitute a local sub network, the connection between the cell tower and the rest of the world begins with a backhaul link to the core of the telephone companys network (via a point of presence).
The capacity for a given system to transfer data over a connection. It is measured as a bit rate expressed in bits/s or multiples of it (kb/s Mb/s etc.).
Bit standards for binary digit: 0 or 1
A byte is made up of 8 bits
It takes 1 byte to store one ASCII character ASCII stands for the American Standard Code for Information Interchange
The combination of bits (which makes up 1 byte) below represents the letters below
A 0100 0001
B 0100 0010
C 0100 0011
K stands for kilo and = 1024 (2 to the tenth power)
M stands for mega. A MB, megabyte is about a million bytes (1024x1024)
G stands for giga. A GB, gigabyte is about a billion bytes (1024x1024x1024)
T stands for etra. A TB, terabyte is about a trillion!
RAM is usually measured in MB
Hard disk spaces are usually measured in gigabytes
Under-served Premises unable to obtain a Metro-comparable Broadband Service.
A blog is information that is instantly published to a Website. Blog scripting allows someone to automatically post information to a Website. The information first goes to a blogger Website. Then the information is automatically inserted into a template tailored for your Website.
Broadband is defined by the ABS (www.abs.gov.au) as an "always-on" Internet connection which can access the internet at speeds equal to, or greater than 256kbps. Whereas your typical Dial-up connection speed is limited to 56kbps.
Abandoned or under-used industrial and commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contaminations.
A browser is a program you use to view pages on the Internet. It allows you to create bookmarks and to move through and forward Internet content.
Churning (or Rapid Transfer) means you are switching from one broadband ADSL provider to another. You are doing so with the least possible disruption to your broadband service, and you are saving on connection costs and time.
An electrical cable consisting of an inner conductor surrounded by an insulating spacer, surrounded by an outer cylindrical conductor. It provides protection of signals from external electromagnetic interference and effectively guides signals from external electromagnetic interference and effectively guides signals.

Unused fibres, available for use. The term was originally used when talking about the potential network capacity of telecommunication infrastructure, but now also refers to the increasingly common practice of leasing fibre optic cables from a network service provider.
The point at which the telephone company network ends and connects with the wiring at the customer premises. A demarcation point is also referred to as the demark, DMARC, MPOE, or minimum point of entry.
Dial-up Internet access is where you dial a phone number to connect to the Internet. It is slower than broadband, and you cannot make telephone calls at the same time.
The unique name that identifies an Internet site on the World Wide Web. On the Web, the domain name is the part of the Uniform Resource Locator (URL) that tells a domain name server where to forward a request for a Web page. For example, the domain name of this website is www.connectingthecoast.com.au
Broadband plans are expressed in terms of download and upload speeds. The higher the speed the less time it takes you to view a web page or download a file. Typically, residential broadband is up to 10 times faster than dial-up Internet which is great for downloading movies and music.
DSLAM refers to Digital Subscriber Line Access Multiplexer. A DSLAM is a network device that receives signals from multiple DSL connections and puts the signals on a high-speed backbone line using multiplexing techniques. Depending on the product, DSLAM multiplexers connect DSL lines with some combination of asynchronous transfer mode (ATM), frame relay, or IP.
Email address (mailbox) is your electronic mail address. Email is like sending someone a regular letter, only there is no postage and it is delivered by computer.
In Windows, DOS and some other operating systems, one or several letters appear at the end of a file name. Filename extensions usually follow a period (dot) and indicate the type of file. For example, this.txt denotes a plain text file, that.htm or that.html denotes an HTML file. Some common image extensions are picture.jpg or picture.jpeg or picture.bmp or picture.gif
In the Internet Explorer browser, a means to get back to a URL you like, similar to Bookmarks.
A firewall is not as exciting as the flaming pyrotechnics show the name suggests. A firewall is actually either a software program or hardware device which protects your computer from unauthorised access when it is online. It blocks out computer hackers and Internet works (a special kind of virus which spreads between unprotected computers over the Internet). It is important to have a firewall, and a common one is Nortons Internet Security. Windows XP comes with an in-built firewall but you need to turn it on.
FTTB (Fibre to the Business) is a form of fibre optic communication delivery in which the optical signal reaches the private property enclosing the home or business of the subscriber or set of subscribers, but where the optical fibre terminates before reaching the home living space or business office space, with the path extended from that point up to the user's space over a physical medium other than optical fibre (eg. copper loops).
FTTH (Fibre to the Home) is a form of fibre optic communication delivery in which the optical signal reaches the end user's living or office space.
Fibre to the Premises (FTTP) is a form of fibre-optic communication delivery in which an optical fibre is run directly onto the customers' premises. This contrasts with other fibre-optic communication delivery strategies such as fibre to the node (FTTN), fibre to the curb (FTTC), or hybrid fibre-coaxial (HFC), all of which depend upon more traditional methods such as copper wires or coaxial cable for "last mile" delivery.
A gigabyte (GB) is a unit of information or computer storage qual to 1000 megabytes (MB) or 1 million kilobytes(kb).
A fully functional global navigation satellite system that enables receivers to determine their speed, time and direction.
A term used to describe a piece of undeveloped land, either currently used for agriculture or just left to nature.
Discussion forums one can participate in, share ideas with, and form community. Most are free and some are open to new members. Yahoo Groups and Google Groups are both popular. Blogs are replacing some of the need for this type of community sharing and information exchange.
Hosting refers to the housing of a website, email or a domain.
A telecommunications industry term for a broadband network which combines optical fibre and coaxial cable.
Text, images, graphics that, when clicked with a mouse (or activated by keystrokes) will connect the user to a new Website. The link is usually obvious such as underlined text or a “button” of some type, but not always.
Your internet speed is the rate at which you can transfer data. The fast your Internet speed, the faster you can browse the web and download/upload files. It is measured in kilo-bits per second (kbps or k). A regular dial-up modem has a speed of 56k, while residential Broadband ADSL usually ranges in speeds from 256k and 512k, right up to a super fast 1500k and ever higher.
IP (Internet Protocol) address is the numeric identification number that refers to a specific machine on the Internet. Every machine that is on the Internet has a unique number, which correlates to its domain name.
A system where a digital television service is delivered using Internet Protocol over a network infrastructure, which may include delivery by a broadband connection. A general definition of IPTV is television content that, instead of being delivered through traditional broadcast and cable formats, is received by the viewer through the technologies used for computer networks.
A unit of information or computer storage equal to either 1,024 bytes (210) or 1,000
bytes (103), depending on context. It is abbreviated in a number of ways: kB, KB, K
and Kbyte.
A LAN is a Local Area Network. The computers at your home are probably connected to a LAN so that they can share an Internet connection, printers and files.
The infrastructure used to provide the link from a Customer’s premises to the Provider’s nearest point of aggregation. For example, a provider offering a wireless broadband service to the Customer would be providing Last-mile Infrastructure using wireless broadband technology.
The physical link or circuit, that connects from the demarcation point of the customer premises to the edge of the carrier or telecommunications service provider, network.
Your mailbox (email) is where email sent to you is stored waiting for you to collect it.
A megabyte is a unit of information or computer storage equal to 1 million bytes or 1000 kilobytes.
A modem is a communications device which allows your computer to connect to the Internet. The word modem is shorthand for modulator/demodulator, which means it converts analog signals into digital signals and vice-versa.
Short for Moving Picture Experts Group
MPEG 1 Format for compressing video with audio for playback from storage media with low data transfer rates such as CDROMs or over the network at VHS quality.
MPEG 2 Format for compressing video with audio at broadcast quality resolution for playback in higher data transfer rate environments. Usually used for real-time encoding in the professional market, satellite digital television, and for DVDs and other types of video CDs
MP 3 Format for compressing audio only defined in both MPEG 1 and MPEG 2. Commonly used for digital music played on personal computers (MP3 songs) but also targeted at applications such as digital phones and new hardware MP3 players intended as discman or car CD player replacements.
A network comprising of wireless, optic-fibre, xDSL, and high-speed satellite service.
A discussion group operated through the Internet.
A broad term to describe some key architectural evolutions in telecommunication core and access networks that will be deployed over the next 5-10 years. The general idea behind NGN is that one network transports all information and services (voice, data, and all sorts of media such as video) by encapsulating these into packets, like it is on the Internet. NGNs are commonly built around the Internet Protocol, and therefore the term "all-IP" is also sometimes used to describe the transformation towards NGN.
A horizontally layered network architecture and business model that separates physical access to the network from service provisioning. The same OAN will be used by a number of different providers that share the investments and maintenance cost.
A glass or plastic fibre that carries light along its length. Widely used in communication because it transmits over longer distances and at higher data rates than other forms of communication.
In information technology, a packet is a formatted block of data carried by a packet mode computer network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a series of bytes, characters, or bits alone. When data is formatted into packets, the bit-rate of the communication medium can better be shared among users than if the network would have been circuit switched.
An Internet point of presence is an access point to the Internet. It is a physical location that houses servers, routers, ATM switches and digital/analogue call aggregators. It may be either part of the facilities of a telecommunications provider that the Internet service provider (ISP) rents or a location separate from the telecommunications provider.
Generally refers to a connection restricted to two endpoints, usually host computers. Point-to-point is sometimes referred to as P2P, or Pt2Pt, or variations of this. Among other things, P2P also refers to peer-to-peer file sharing networks. A traditional point-to-point data link is a communications medium with exactly two endpoints and no data or packet formatting. The host computers at either end had to take full responsibility for formatting the data transmitted between them.
Rapid Transfer (or Churn) means you are switching from one Broadband ADSL provider to another. You are doing so with the least possible disruption to your broadband service, and you are saving on connection costs.
A lot of people like to kick their computers. A reboot, however, usually means shutting down your computer or modem and then restarting it. Unless your computer has frozen, it is bets to use the shutdown or restart commands. Some modems do not have a reboot button, but you can just power them off and on.
Also known as a Digital Loop Carrier (DLC)system which uses digital transmission to extend the range of the local loop farther than would be possible using only twisted pair copper wires. A DLC digitizes and multiplexes the individual signals carried by the local loops onto a single data stream on the DLC segment.
Short for “Really Simple Syndication” (aka Rich Site Summary or RDF Site Summary), refers to a group of XML based web-content distribution and republication (Web syndication) formats primarily used by news sites and weblogs (blogs). Any website can issue an RSS feed. By subscribing to an RSS feed, you are alerted to new additions to the feed since you last read it. In order to read RSS feeds you must us a “feed reader”, which formats the XML code into an easily readable format (feed readers are to XML and RSS feeds as web browsers are to HTML and web pages.
A Service Solution delivered by a two-way satellite service, or other service determined by the Department to be satellite based.
Shaping refers to the slowing of your Internet connection speed to normal ‘modem speed’, to around the speed of 56k dial-up connection. If you have a flat rate broadband plan, shaping will only occur if you have exceeded your monthly download allowance. Although your Internet connection speed will decrease when you are shaped, you will still have full access to the Internet. Once shaped, you remain at modem speed until the net month rolls over.
Spam is unsolicited junk email which someone has sent to you. Spam is usually advertising or an attempt to trick you into giving out personal details. About 20 billion spam messages are sent per day that’s 7.3 trillion annoying messages a year! You should never reply to a spam message as you’ll let the spammers know that they can target you.
TCP/IP (Transmission Control Protocol/Internet Protocol) this is the suite of protocols that defines the Internet. Originally designed for the UNIX operating system TCP/IP software is now available for every major kind of computer operating system. To be truly on the Internet, your computer must have TCP/IP software.
Commonly abbreviated TB is a measurement term for data storage capacity. The value of a terabyte based upon a decimal radix (base 10) is defined as one trillion (short scale) bytes, or 1000 gigabytes.
Is a Service Solution delivered by ground based networks, including ADSL, cable type services, wireless services, or any other service determined by the Department to be terrestrially based.
Broadband plans are expressed in terms of download and upload speeds. If you are sending a big file the time it takes to leave your outbox is the upload speed.
Computer viruses are malicious programs which attack your computer. A bad computer virus can delete files and make your computer run at snail pace. Opening an email with an infected attachment is the most common way to get a virus. Some viruses now even fake messages from your friends to try to trick you into catching them. Luckily you can protect yourself by running an anti-virus program which stops viruses. Common anti-virus programs include Norton Anti-Virus® and McAfee VirusScan®.
VPN is a Virtual Private Network, a private data network that makes use of the public telecommunication infrastructure, maintaining privacy through the use of a tunnelling protocol and security procedures. People use remote logon to their work networks using this facility.
A WAN is a Wide Area Network. This is a network which covers a wide distance. The Internet is the largest WAN in the world.
WiMAX — Worldwide Interoperability for Microwave Access - a wireless technology that provides high-speed broadband connections over long distances. It is not a mobile platform; it is specifically designed for optimum broadband performance. It is internationally recognised as a technology that delivers the highest quality wireless broadband.
Wireless Broadband is an ultra high speed Internet connection similar to SHDSL that does not require a phone line.
