The BlogCall costs are calculated (in part, at least) using the number of seconds, multiplied by the billing rate. Per second billing increment phone plans typically save approximately 5-15% compared to a 30 sec billing increment plan.
Call costs are calculated (in part, at least) by finding the number of billing increments used (in this case 30 seconds), and multiplying by the billing rate per increment. For example: 30 second billing increment phone plans will charge the same amount for call durations 6 sec, 14 sec, and 30 sec. They will also charge the same for calls which are 31 sec, 44 sec and 60 seconds.
The ACCC is an independent body which provides general consumer protection and competition regulation across all industries. It administers the Trade Practices Act. The ACCC also regulates competition in the telecommunications industry through administration of the Telecommunications Access Regime (the ability to choose alternate providers of telecommunications services) and regulation of anti-competitive conduct.
Monthly charge from a service provider for provision of that service. Call charges are additional to this charge. Also may be referred to as a Service Fee or Connection Fee. Distinct from a Connection Charge, which is the charge for connection of an individual call.
A not-for-profit organisation dedicated to ensuring that those who are deaf or have a hearing, speech or communication impairment, can obtain access to the telephone and other telecommunication networks.
The Australian Communications and Media Authority (ACMA) is responsible for the regulation of broadcasting, radiocommunications, telecommunications and online content. Incorporates the former ABA (Australian Broadcasting Authority) and ACA (Australian Communications Authority).
Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines.
A technology for the delivery of faster ADSL. Exchanges must be ADSL2+ enabled. Speeds available start at 24000/3000 kbps and reduce with distance from the exchange, hardware used, quality of the copper pair used, etc.
A representative who acts on behalf of other persons or organisations. Or, a businessman who buys or sells for another in exchange for a commission. In Australian telecommunications an agent is typically a person or company who has a contractual agreement with a Service Provider, whereby they will obtain commission or similar for bringing new customers to that provider.
The AMPS network in Australia was the first mobile phone network. This network was subsequently replaced by digital networks, such as GSM, and is no longer operational. Security and capacity were limiting factors of the AMPS network. The AMPS network is sometimes referred to as the 1G Mobile network; where 1G indicates `First Generation`.
AMTA is an industry body representing and promoting the interests of organisations involved in the supply and provision of mobile telecommunications services and products. Members include: mobile phone carriers and service providers, handset manufacturers, retail outlets and associated business such as those that provide network equipment and specialised consultancy services.
The technology originally used to transmit radio (including mobile phone) and TV communications. Superseded in many communications areas today. Digital communications are now being used in mobile telephony and TV delivery is broadcast using both analog and digital methods.
Prefix added to a phone number to denote the location of that number. In Australia, interstate calling often requires an STD area code. Follow this link for a list of all Australian area code an prefixes.
Verification of the identity of a user to a network, or a network to the user. Passwords, digital certificates, smart cards and biometrics can be used to authenticate a user. In the case of mobile phones, a user may be authenticated to the network to ensure that they are `activated` - with an account and credit on that network. Conversely, Mobile networks may authenticate themselves to a user`s mobile phone to ensure that the phone is locked to their network.
Commercial term meaning Business-to-Business commerce, as distinct from Business-to-Consumer or Retail Business.
The electronic `spine` of a telecommunications network which joins slower and dispersed network elements. A common telecommunications backbone in Australia carries network traffic between Melbourne and Sydney and is a private, managed network. Telstra, Optus and AAPT all have such networks.
The account number attached to a service(s). Most often a customer will only have a single BAN from a service provider. However, customers may elect to have several BANs; to designate between sites, for example.
Refers to the amount of data that can be transmitted in a fixed amount of time. For digital devices, the bandwidth is usually expressed in bits per second (bps) or bytes per second.
These are the letters, which appear on your bill beside the calls you have made, eg. O for off peak and P for peak.
Blocks of time, usually 1 second or 30 second blocks, which are used by a service provider to calculate the cost of a call. Example: If a mobile phone plan states that calls are billed per 30 seconds, then calls lasting 3 sec, 14 sec and 30 sec will all be billed the same; as one 30 second billing increment. However, a 31 sec call will be billed as two billing increments. Example: If a mobile phone deal states that calls are to be billed in 1 second increments, then all calls are billed per second. Typically, billing in 1 sec increments will be approximately 5-15% cheaper than billing in 30 second increments.
The smallest unit of information on a computer, a bit, is expressed by a 1 or a 0. A kilobit equals 1,000 bits. A megabit, 1 million bits.
The BlackBerry from RIM Corporation, is a handheld wireless device providing e-mail, telephone, text messaging and web browsing and other wireless data access. In Australia, BlackBerry operates mostly on the GPRS network. However, BlackBerry will begin operating at higher speeds as networks are upgraded.
Bluetooth® complements wireless LAN perfectly by providing a quick and easy way of connecting one Bluetooth®-enabled device to another without going through your network. For example, you could print a document at a satellite office from your laptop to any Bluetooth®-enabled printer within range (Bluetooth®, products work over shorter distances than wireless networks - approximately 10 metres). In addition, by creating a temporary network, (also known as a personal area network - PAN) you can exchange files at informal meetings - say, around a client`s conference table. Put simply, Bluetooth®, provides the opportunity for flexible, spontaneous working, especially if you don`t have the time to connect to a fixed or wireless network.
Bits per Second. A measurement of data transfer speed. Rates are the number of bits that are transmitted per second. See also Kbps
see VoIP
see VoIP
A software application which facilitates interaction with the World Wide Web. A browser uses HTTP to interact with Web servers online. Also called a Web Browser.

The barring of outgoing calls, to selected numbers or groups of numbers, may be applied to both mobile phones and fixed services. This is a network feature.
A call centre (or Call Center) is a business unit whose purpose is to handle inbound/outbound telecommunications traffic for a company. A Contact Centre is more highly integrated and such a unit might handle various forms of correspondence between the company and its customers.
The saturation of the available simultaneous connections on a communications channel by users. Applies to both Fixed Lines services and Wireless services (including Mobile services).
Often also called Call Forward, Call Divert is the ability to divert an incoming call to a designated number or service. Usual call charges often apply (however some of these charges might be reduced or removed by some Mobile service providers). Available to both Mobile and Fixed Line services. Call diversion products typically offer many conditional options (eg. Divert All Calls, Divert on No Answer, Divert on Unreachable, Divert on Busy, etc.).
The ability to alert the user to the presence of a second incoming call to their current connection. The user has the option to retrieve the second call, while maintaining their initial connection. Either party may then be disconnected by the user, at their discretion. This feature is available for both Fixed Services (although not all types of Fixed Services) and for Mobile Services.
Also referred to as CID. This feature provides the caller`s telephone number information whilst the call is ringing. The CID information is usually contained between the first and second ringing tone. CID may be blocked (on landlines) by the caller by dialling 1831 before the number, or by requesting a permanent block from the service provider. This information is obtained by using the relevant parts of CLI (Caller Line Identification) information.
Often referred to as Rebillers or Resellers of telecommunications services. These are service providers who are not carriers themselves such as telaustralia.
Telecommunications Carriers are the owners/maintainers of a telecommunications network (either Mobile or Landline). Not all Telecommunications Providers are Telecommunications Carriers; some are resellers of a Carrier`s network.
CDMA (code-division multiple access) refers to any of several protocols used in so-called second-generation (2G) and third-generation (3G) wireless communications. A CDMA service with Optus means that you have a handset that uses this technology and is carried on the Telstra network. A CDMA handset may be an option for those that do not have Optus digital coverage in their area. It is planned to close the Australian CDMA network in January 2008 and replace it with the Next G network.
Term to denote the switch of a customer between telecommunications service providers.
The provision of the calling party`s number, called party`s number, time of call, routing information, duration and other minor information between service providers. Often billed as CLIP - Calling Line Identification Presentation. Part of this information may be used to provide CND (Calling Number Display) to the called party.
The display of the calling party`s number as the call is ringing. CND is typically sent (as an inaudible signal) between the first and second dial tones of a call. The caller may elect to have their CND information blocked on a per call basis (by prefixing the called number by 1831) or permanently blocked through their service provider. Also called Calling Name Display, Caller ID (or CID) and CNI (Calling Number Identification). CLI differs from CND and the others. See also CLI (Caller Line Identification).
A one-time fee for the set up your phone service. Not to be confused with a Flagfall, which is the connection cost of an individual call.
For Telecommunications: As communications transmission and storage has become digitised, consolidation of various forms of communications (eg. voice, data and video) has become a possibility. Convergence is the likely joining of two or more communications forms into a single user product. The advantages for consumers are: convenience and cost savings. The advantages for service providers are: cost savings (through reduced operational expenses and capital expenditure) and increased customer loyalty.
The Australian telecommunications network mostly remains a simple copper network. Also know as POTS (Plain Old telephone Service) This describes copper lines connected to premises from local exchanges and then switched through other exchanges, for ultimate delivery to another premises. Telecommunications transmissions travel over these lines. Today, there are other methods of telecommunications transmissions such as IP networks, satellite networks, wireless networks (including Mobile Phone Networks).
The dialling prefix used to reach international destinations. To access IDD (International Direct dialling; dialling internationally without operator assistance) the access code 0011 must be used. The format for IDD is: 0111 + country code + area code + local phone number.

Operator-assisted (or possibly a CVR-assisted) telephone directory service which provides the user the phone number of a residence or business. Number must be listed in the telephone directory.
A non-broadband internet connection to an ISP. The connection is made by a modem dialling the ISP through the traditional PSTN network.
The use of a 100 InDial Range with a PABX, which allows an outside caller to dial a phone number that will ring directly to a specific party instead of calling a main phone number. The PABX must be programmed to assign that number to a specific extension.
The representation of information using discrete elements called binary code. In everyday use (especially in voice communications) digital signals are used to represent analog information. Digital signals are useful because they can represent analog signals, can be easily handled by computer systems and networks (themselves, digital systems), can be compressed, and do not degrade with reproduction.
Use of an existing `subscriber line` (traditional phone line) to deliver digital data at broadband speeds. The local exchange (where the copper loop telephone line is connected) must be `enabled` with DSL technology.
Previously direct dialling was the event of dialling an intended party without the aid of an operator. Nowadays, Direct Dialling is still commonly used in two circumstances. IDD (International Direct Dialling) is connection to an international destination without the aid of an operator. IDD is still in use in vernacular because pricing structures quote IDD rates. The second common use for Direct Dialling is for Direct In Dialling (called `Direct Dialling In` by the Brits). Direct In Dialling is where a phone system (PABX) can recognise an incoming dialled number, bypass the main answering point (eg. the receptionist), and pass the call directly to the correct extension. DID usually requires a 100 number range.
Operator-assisted (or possibly a CVR-assisted) telephone directory service which provides the user the phone number of a residence or business. Number must be listed in the telephone directory.
A server which translates the URL of a website into its actual numeric IP address. When a browser requests a web page, the domain name server is consulted for the actual IP address. Humans use words to define web addresses, computers use numeric IP addresses.
A call within Australia.
The accidental disconnection of a phone call. Applies to both Fixed Line services (including VoIP) and Mobile Services. VoIP users also call partially missing words a `drop-out`.
Also called a Digital Subscriber Line Access Module or a Mux. This is a hardware interface between DSL lines and a network `backbone`. DSLAMs are located in the local exchange. DSLAMs also provide the interface for ULL supply of voice/internet connections - these internet connections are usually faster than normal ADSL connections.
Since 1993, Mobile digital networks in Australia have been built using a frequency (or band) of 900MHz. In 2000, the three digital carriers (Optus, Telstra, Vodafone) started to introduce a new technology, which uses a frequency of 1800MHz. Most 1800MHz base stations are not stand-alone - they are built on an existing 900MHz base stations. This is called a "Dual Band" base station - because it can transmit on two different frequencies. By rolling out GSM1800 sites, we are able to provide additional capacity to customers who have a dual band phone. The rollout of 1800 sites and cost is much less than building a brand new site. The equipment required to operate GSM1800 is located in the same shelters as the GSM900 equipment.
The ability of a mobile handset to operate on both the analog and digital networks; even to the extent of using the same frequency band.
The ability for both ends of a communication to send and receive data. Telephones are a Duplex communication because both parties can talk at the same time; 2-way radios are half-duplex because only one party can talk at any one time.
Mail composed and transmitted on a computer system or network. Email is technically merely text, but multimedia attachments often accompany it.
Designed to extend the PPP (Point to Point Protocol), the EAP incorporates traditional passwords, token keys, digital certificates and public-key authentications.
E-mail (electronic mail) is the exchange of computer-stored messages by telecommunication. Generally text messages, non-text files such as graphic images and sound files can be sent as attachments. E-mail was one of the first uses of the Internet and is still the most popular use. A large percentage of the total traffic over the Internet is e-mail. A popular protocol for sending e-mail is Simple Mail Transfer Protocol (SMTP) and a popular protocol for receiving it is POP3. Both Netscape and Microsoft include an e-mail utility with their Web browsers.
Telephone numbers for the Emergency Services: Police, Fire & Ambulance. These numbers are free to call and should only be used in situations which are life threatening or there is imminent risk to either property or the environment. Related: 000 - Emergency, 106 - Emergency for TTY, 112 - Emergency for Mobiles

The process of encoding data. Data is often encrypted before it is transmitted over an unsecure medium, then decrypted at its destination using a process or key for that purpose.
The area serviced by a local phone exchange. These are often used when describing 1300, 13 or 1800 number call routing.
All CDMA phones have a unique Electronic Serial Number (ESN). When you activate the phone on the CDMA network, the ESN is linked to the CDMA service and phone number.
The unique hexadecimal serial number of a CDMA phone (and previously, analog mobile phones). The ESN is registered with a service provider as part of a mobile`s activation process. See also IMEI.
The amount charged by a service provider for the early termination of a contract. For Mobiles, this is usually the number of months remaining on the contract multiplied by the minimum monthly commitment of that contract. For Landlines, this is often the repayment of any previously granted bonuses and the payment of a nominated monthly amount multiplied by the remaining months of the contract period. Also called a Cancellation Fee, Contract Cancellation Fee, Contract Termination Charges, etc.
Ethernet is the most widely-installed local area network (LAN) protocol.
Officially, Ethernet (at up to 10Mbps) and Fast Ethernet (at up to 100Mbps) are
the two grades. Now the term Ethernet generally refers to Fast Ethernet, due to
this being the prevalent type used. Ethernet is generally transferred using
CAT-5 or CAT-5e cables (`the blue computer cables`), or over a wireless
LAN

IP address of a computer on an external network - most commonly the internet. Computers use IP addresses to identify one another. Websites are held on servers, and are assigned a unique IP address. Mail servers also have a unique IP address. External IP addresses may also be called Public IP addresses.
Called a fax in common use. The digitisation of an image and then transmission of that image. Superseded the Telex.
Feature of a mobile phone which allows data to be sent and received as per fax protocols.
Telstra product. Duet refers to the addition of a second line which shares the same telephone line as an existing service. Line rental for the second line is minimal (around $6.00). Faxes may still be received while the line is busy, and are queued at the exchange until the line is free. FaxStream Duet has become a valuable tool for many small businesses.

Delivery of calls to a user through multiple numbers at the same time such as desk phone, mobile phone and home phone simultaneously allowing the customer to pick up the call regardless of location. Available on Telaustralia Total Business Connect (TBC).
Delivery of calls to a user through an alternate network (while that user is out of range from their pre-selected network or whilst that user has requested the routing). See also Roaming.
Typically used for LAN to LAN data connection over distances, frame relays are prescribed connection paths. The end user experience is a (virtual) permanent connection between LAN sites. Frame relay is a protocol for variable-length packet transmission of data. Designed for use as a low-noise connection, redundant- and dark- data are not generally used, which leads to high transmission rates. Frame relays may transmit bursts of data at up to 45Mbps. Due to its transmission burst nature, frame relays are not ideal for transmission of continuous signals such as voice and video.
1800 Number. A FreeCall number is a Toll-Free number but with no connection charges. The call is charged to the owner of the number. As with all toll-free numbers, the call is routed to a nominated answering point. The answering point itself may be dynamic; it may be dependent on time of day (TOD), caller location, or calling traffic overflows.
Process for transferring files over the internet or another TCP/IP network. FTP is also often used to describe the software interface used for transfers. Files available to be shared are held on a server. Users may be required to logon to the server using either a secured username and password or by an `anonymous` logon (an unsecured and generic logon). Files may then be downloaded from the server (or uploaded, if permitted).
The ability to use a mobile phone overseas. Tri-band and Quad-band phones allow roaming through the USA. GSM and GPRS phones will provide roaming throughout most of the international community. CDMA phones do not (practically) offer international roaming. Roaming charges are substantial.
GPRS stands for General Packet Radio Service, this standard allows packet rather than circuit switch connections on cellular networks. This allows high-speed mobile access and the ability to connect to the mobile network when Internet access is required.
GPS is short for Global Positioning System, GPS refers to satellite-based radio positioning systems that provide 24 hour three-dimensional position, velocity and time information to suitably equipped users anywhere on or near the surface of the Earth (and sometimes off the earth). GPS technology is used in a wide range of applications, including maritime, environmental, navigational, tracking and monitoring.
Goods and Services Tax (GST) is a federal Government initiative and is a 10% tax on most goods and services supplied. Every business that supplies goods and services collects GST for the Australian Tax Office. This means that the price of their goods and services include a GST amount.
Overall, a handset is any hand-held device which is used to make and receive phone calls. Refers to mobile phones, cordless phones or landline handsets. However, usually refers to a mobile phone handset. Also called a mobile, cell, cell phone or cellular phone. Cordless handsets are also called portable phones, DECT phones (common-use language) or wireless phones. Landline handsets may refer to a stand alone handset directly connected to a socket or to a handset which is part of a phone system (eg. a handset connected to a PABX).
Mobile phone handset, which is included in the offer of a mobile phone contract. The handset may be subsidised, free or $0. Subsidised handsets may be bought outright or included as a monthly charge. Free handsets are free, with `no strings attached`. $0 (called `zero-dollar`) handsets are offered at no charge, so long as the customer remains in contract with the provider. After the contract period is finished, a $0 handset is owned by the customer.
The ability to converse on a mobile phone without using one`s hands to hold the handset.
Signals between two network nodes (eg. a mobile handset and a base station, a wireless laptop and a wireless router, etc.) which precede interoperation. Often a handshake will incorporate security authorisation.
Symmetric DSL which usually has a slower maximum download speed than an ADSL over the same connection. Useful for high levels of data being sent and for VoIP applications.

Non-profit organisation which is the worldwide central body for administration of IP addresses and domain names used on the internet.
Connection of a call to an international destination number without the aid of an operator. IDD is still in common use because it is used to quote international calling rates. IDD can be done from fixed lines or from mobiles. Not to be confused with international roaming calls, see below.
Global standards for 3G mobile network performance, from the ITU (International Telecommunications Union).
Alternately called an in-place number or an in-place line. The service may be reconnected without a technician site visit. A service is in-place if there has been a previous connection at the address and the line remains in-place. A phone line with a dial tone is an in-place service, and in some cases a line without a dial tone may be considered in-place.
The cost of calls, messages and other uses which the minimum monthly cost allows. May apply to mobiles or to landline phone services. Most often, the included calls match the minimum monthly spend. Included calls may be measured in minutes or in dollar value.
Infrared is similar to Bluetooth in that it`s another method of peer-to-peer networking. Here data is transmitted via radio waves across short distances from device to device. (The range data can be sent using infrared is shorter than with Bluetooth.) You could, for instance, send a text document to a colleague by bringing your notebooks close together and exchanging the data via each device`s infrared port.

See VoIP
Non-visible part of the EMS (Electromagnetic Spectrum) which can be used as a wireless communications medium. Line-of-sight transmissions only.
Integrated services over a traditional telephone line. The line is altered at the exchange to provide either an ISDN2 or ISDN10/20/30 connection. ISDN2, also called BRI, is a converted single copper pair into two 64 kbps `B` channels which may be used for voice or data. There is an additional 16kbps `D` data signal channel created also. ISDN2 can be used to provide 2 voice lines on the same copper pair. ISDN10/20/30, also called PRI, is a converted single copper pair (ordinary telephone line) into thirty 64 kbps `B` channels which may be used for voice or data. There is an additional 64kbps `D` data signal channel created also. ISDN10/20/30 can provide 10, 20 or 30 voice channels over the same copper line.
Company which retails internet connections to customers. An IAP (Internet Access Provider) wholesales bandwidth to ISPs, who in turn package and sell the bandwidth to the end customers. ISPs have also extended their range of products, often providing website hosting and other products.
Presentation of a phone bill on a call-by-call basis. Itemised calls show call information such as: number called from, date of call, time of call, number called, duration of the call, and the cost of the call. Often additional information is supplied, such as: rate plan applied to that call, whether the number dialled is considered OnNet, and others. Aussie Phone Brokers makes use of this information to recalculate each phone call according to a range of plans applied.
Interactive Voice Response - is the interface between your phone and a computer system. It is the voice recording that asks you to select an option when accessing such things as voicemail.
Object based programming language. Intended to replace C++. (Mentioned in this glossary to note that Java and JavaScript are not the same thing.)
Script language which can be embedded into the HTML of a web page to add functionality. Unlike a programming language, a script is simplified and does not need to be compiled, the source code is embedded into the HTML of a webpage. Developed by Sun Microsystems, JavaScript is open source and may be used without purchasing a licence.

A popular satellite communications frequency band operating between 10-18 GHz.
Local area networks are independent fixed wire networks that make up your fixed network. Cables and wires connect each device to your servers. LANs are the most common type of networks used, but this may not be the case for long - wireless local area networks are becoming more popular.
A network of computers within a home, office or group of buildings. Often connected via Cat-5 cables (the `blue computer network cables`) or by local wireless connections (eg. wireless routers).
Also called a Fixed Line service, Fixed Wire service, Wired service, Telephone line, POTS (Plain Old telephone Service) Phone line, Land Line, CO Line, Central Office Line and Copper Connection. These are the traditional copper telephone connections, from an exchange (CO) to a premises. Today landlines also describe fibre optic telephony lines. Generally speaking, a landline is a non-wireless telephone line.
A flat display used in electrical equipment. Early versions were two-toned, but today LCDs are colour. LCDs are used on handsets; both mobile (including PDA, etc.) and landline handsets.
Programming of a PABX to use different lines or override codes to obtain the best call rate for differing call types or time of day calling. For example: When calling a mobile phone, a PABX which has been LCRed may use an alternate (cheaper) carrier for that call. This is simply done by prefixing the dialled number with a four digit override code. The user does not see or notice the LCR taking place.
A dedicated telephone line assigned from one location to another. Set up by a telecommunications carrier, the connection is said to be a leased line. Typically used by businesses to connect geographically distant offices, leased lines are more expensive than other methods available today (eg. VPNs). Leased lines offer an inherently secure, fast and always-on connection.
Small, bright, light source that uses very little power and does not burn out. LEDs may emits visible, UV or IR.
LEO satellites are more common than GeoSats because it is cheaper to place them in LEO and they need less powerful amplifiers for transmitting. LEO is an orbiting height of between 200 and 2000 kms and the satellites travel at about 27,400 kmph to maintain their orbit - providing a period of orbit of around 1 hour and 30 minutes. This means that constant coverage to an area on Earth must be provided using a network of LEO satellites. (This is unsuitable for some communications requirements and so geostationary orbit satellites are also used - see Geosynchronous Satellite.)
The number of lines of text which can be displayed on a handset without scrolling. Not to be confused with CND (Calling Number Display).
The fee charged by a telephone carrier for the connection to their network. Distinct from usage charges, this fee is a flat access fee.
A stationary wireless broadband link which must be operated in line-of-sight. 3-5km ranges are expected.
Calls made between standard telephone services within the same charging zone or to adjacent standard charging zones, and charged at a flat rate. However, local calls from ISDN services are timed and do not have a flat charging structure.
A charging arrangement that allows dial-up internet users to access their (ISP) Internet Service Provider for the cost of a local call, irrespective of their distance from the physical point of presence (PoP). See 019 numbers.
The telephone exchange (see CO) which a standard telephone service is physically connected to. This is usually the closest exchange, but not always.
The ability for a customer to retain their existing landline number when changing service providers. This may occur in two circumstances: either the number is retained by the carriage service provider and simply rebilled, or the number is actually ported from one carrier to another. As with mobile number porting, the approximate time where the number is unavailable through either of the carriers is 15 minutes.
Long distance calls are also called STD calls, NDD (National Direct Dialled) Calls or Trunk Calls. (Technically, international calls are also long distance calls, but this is not a common use of the term.) These are domestic calls which extend beyond local billing zones.
Refers to a communication medium which must have an unimpeded (or nominal) line-of-sight between transmitter and receiver.
The point in a commercial building where Telstra lines enter the building and where the network connects to the internal cabling. When adding new lines to commercial premises Telstra will only connect to the MDF and the customer needs to arrange their own Phone Technician or Cabler to Jump (connect) the internal lines to the Telstra line.
The MAC address is the physical address of a device connected to a network. This unique hardware identity can be used to allow devices access to networks such as a wireless area network (WLAN) via an access point.
Megabits per second (a million bits per second) is a unit used to measure the rate of information transfer. [A bit, short for binary digit, is the smallest unit of information a computer can hold]
The series of 019 numbers which allow national dial-up internet access at the cost of a local call from almost anywhere in Australia.
Using the phonebook features of a phone handset to retrieve and call a number. Speed dial is one example of this. Dialling using number recall features is another.
Loss of capacity of Ni-Cad (Nickel-Cadmium) or NiMH (Nickel-Metal Hydride) rechargeable battery. Recharging the battery before it is completely discharged, or using the battery before it is completely recharged, can result in that battery losing the ability to reach its original capacity. This effect may be reduced through several full discharge and charging cycles. Nowadays NiCd and NiMH batteries are not in prevalent use.
Also called ICO (Intermediate Circular Orbit), denotes satellites placed in an orbit greater than LEO (Low Earth Orbit) and less than GEO (Geostationary Earth Orbit). The satellites for the global navigation system GPS (Global Positioning System) operate in MEO.
Telstra product brand name for a voicemail service. For landlines: Callers can be directed to MessageBank when their call is unanswered or if the phone is busy. For mobiles: Callers offered by Telstra for its fixed-line customers. You can check your messages from any phone by calling your MessageBank and entering your secret PIN. There is a monthly fee added to your phone bill for this service.
Telstra product. Callers may use a non-connected (virtual) number to leave messages.
Microwave telecommunications is the use of microwaves as a communication medium. Microwave communications are restricted to line-of-sight only.
Different to a Flagfall cost, the minimum call cost is the minimum charge for an individual call. Difference: Whilst the Flagfall is charged at the connection of a call and then rate charges added, the minimum call cost is only applied if the call cost does not exceed minimum amount.
Term used to describe the total commitment amount of a contract. For early termination of a contract, payment of the minimum commitment will often be enforced. See also Minimum Monthly Commitment.
See Minimum Monthly Commitment
The agreed monthly charge for available connection of a service to a network. This minimum charge will still be applied, irrespective of usage. For instance: A $99 Cap plan, with $700 of included calls and a minimum commitment of $70, will cost $70 per month even when the phone is not being used. Also called a Connection Fee, Minimum Commitment, Monthly Access Charge, Monthly Access Fee, Monthly Connection Fee, etc.
Wireless broadband alternative to the local loop (traditional copper connections) and permits a high bandwidth traffics up to 10 Mbps.
An EMS (Electronic Messaging System) used to deliver text, images, sounds and limited video to mobile handsets. Platform built to expand SMSs.
The ability for a customer to retain their existing mobile number when changing mobile service providers. Mobile numbers are assigned to SIM cards and a mobile number port occurs like this: Usually a new SIM is issued, with a temporary mobile number imprinted on it. Then, when `the port` happens, the existing number is written over the new SIM`s temporary number and the old SIM is left inactive. During the mobile number porting, the mobile number is unreachable through either carrier for approximately 15 minutes.
The locations in which a user can connect to and use a mobile service from a nominated mobile phone network. The Australian carriers all supply generalised Coverage Maps of their coverage areas.
A call type denoting a domestic call made from one mobile to another. For the purposes of billing, call rates between mobiles are often charged at a different rate to other call types. (Sometimes mobile to mobile call rates are segregated further; according to OnNet calls and OffNet calls.)
Amalgamating the terms: MOdulator and DEModulator, a Modem is a hardware device used to convert communications signals between analog and digital, or to modify digital signals between two parts of a network. Modems are commonly used to connect a PC to the internet.
Simplistic ringtones which are made up of monophonic beeps. Monophonic means: Capable of producing only one note at a time.

Method used to transmit data from several sources along a single communications path, and be able to retrieve the intact information from any point along the path also.
Distinct from a mobile service provider who acts as a reseller of mobile network services, a MNVO buys wholesale capacity from a mobile network carrier and retails its own services. Telaustralia acts as an MVNO.
Internet infrastructure element where IAPs connect to other IAPs, or where IAPs connect to their ISPs. NAPs are major connection nodes of the internet. Often a point of congestion, an efficient NAP leads to a faster service.
As compared to Broadband, which uses a broad bandwidth for signal transmission, Narrowband uses a much narrower bandwidth and is therefore unable to carry information at broadband rates.
Policy framework for broadband development in Australia, agreed by all levels of government. Overseen by the National Broadband Strategy Implementation Group.
Term used for both landline calls and mobile calls. Landline: See STD. Mobiles: Any call to a domestic fixed line which is not a service number or premium number.
Subset of Local Calls, a neighbourhood call was made within a local exchange area and was cheaper than a standard local call.
NetAlert is a not-for-profit internet safety advisory body established in late 1999 by the Australian government to provide independent advice and education on managing access to online content.
Telecommunications: Network is a telecommunications connections infrastructure which enables telecommunications between two or more devices. Computers: Network is a data communications connections infrastructure between three or more computers.
Mobiles: New Service is the connection of a new mobile phone to a network,
with a new number applied. Porting of a service to a new carrier is not
considered a new service.
Landlines: New Service is the new connection
between a customer`s premises and the local exchange. Activating an in-place
number is not considered a new service even though that customer may be new. A
new service will involve at least some physical work between premises and
exchange. Sometimes a new service will involve trenching a new group of copper
lines onto the premises site.
Diversion of an unanswered call to another number or a message service. The number of rings before a call diverts can be set by the service provider. See also Call Divert.
A mobile phone which is out of range of its service provider`s coverage area (and any associated roaming service providers` coverage areas also) is said to be in a No Service area. Remote regional areas are No Service areas for most providers. See also Coverage Maps, for No Service areas from each mobile carrier.
A carrier in respect of whom a nominated career declaration is in force under section 81 Telecommunications Act 1997.
Each USO provider is required to report regularly to the ACMA (incorporates the former the ACA) on the performance of its network at a the FSA, ESA and individual phone services level. The ACMA may issue directions requiring the USO provider to remedy individual services.
A telephone access service for communications to or from hearing or speech impaired individuals. Relay may be through a live operator or through direct means such as TTY services. See also ACE.
The ability for a customer to retain their existing phone number when changing service providers. Term applies to both Local Number Portability and Mobile Number Portability.
Retrievable cost of a carrier providing access to the standard telephone service and payphones. The carrier is required to submit a claim to the ACA (now ACMA) for these NUSCs in order to be reimbursed. The calculations examine operating and capital costs (including the opportunity cost of capital) for the loss-making services, less any revenue received for those services.
Rate plan feature from Service Providers. Off Peak rates are discounted rates designed to encourage the use of a service provider`s communications services at a time which is convenient to them - their off-peak traffic times. Off Peak times are generally nighttimes and weekends. See also Economy Rates.
Internet connection using a satellite download link and a landline for the upload link. Often used in conjunction with the an ISDN2 connection to provide a 64kbps or 128kbps upload link. This connection has generally become superseded in regional areas, with the introduction of the Two-way Satellite connections (offering 256kbps uploads, for example, without the monthly connection costs).
Public areas which provide user internet access, with user equipment supplied. Libraries are a good example of an Online Access Centre.
Phone calls which are made between users of the same network. For example: Calls between Optus mobiles are OnNet, but a call from an Optus mobile to a Vodafone mobile are OffNet. Also called Same Network Calls, or branded (eg. Virgin2Virgin Calling). Calls within the same account are OnNet calls, but are called Intra-Account Calls.
Glass, plastic or hybrid fibres which are used to transmit digital pulses of light for data transmission. High bandwidth, high integrity (low data loss) solution which is used carry voice, video and data signals.
An extension which is located remotely from a PABX. OPX was an expensive service offered by service providers and was little used in the past. OPX is gaining great interest with the introduction of IP telephony and VoIP. OPX allows secondary office phones (and employees at home) to use their handset as though they are connected to the PABX. Extension dialling, call transfers, etc. become available with OPX.
Telephone call to an external party.
Each Australian service provider has its own four digit override code. Calls to domestic or international destinations may be made through a provider by dialling their code before the required number. Override codes may be used on a call-by-call basis. (The user should also have an account with that provider, otherwise the call may be blocked.) Pre-programming a PABX to use override codes for certain call types is one form of LCR (Least Cost Routing).
A phone system which allows not only onsite/offsite connections (eg. incoming and outgoing calls) but also onsite/onsite connections (eg. calls to extensions, call transfers, etc.). A PABX (sometimes called a PBX) is the actual phone system box. The handsets are the extensions. Common features of a PABX are: extension dialling, call transfer, call holding, conference calling, DID (Direct In Dialling), CND (Calling Number Display) overwriting, CID (Caller ID) pass-through, and LCR (Least Cost Routing). PABXs superseded KTSs (Key Telephone Systems).
Usually IP networks, data travels over the communications links as data packets. This enables links to be shared (carrying packets from multiple sources). IP networks can often show reduced network (switching) errors, but may introduce delays to packets when the communications channels are congested.
These protocols, of which the IP is the most common, are rules for formatting the breakdown of data into discrete packages, called packets. A data packet is composed of a header and a small part of the data. The header is generated by the protocol and contains the address of the packet`s destination. Packet switching is very efficient because at each stage of routing only the address (or part of the address) is read and not the entire data packet. (A useful analogy is a mail sorting room: the letter (data) is not read, just the relevant part of the address.) Because packets all have an address, they may be sent via any available communications channel and data from multiple sources may be sent via the same communications channel. This is another efficiency gain.
The act of routing a data packet and also deciding Most commonly, the act of routing IP packets through the internet. Packet switching not only includes the act of redirection of each packet, but also manages the decision making of each routing node.
Mobile Technology: Largely superseded technology whereby a wireless device could receive text messages to a small device called a pager. SMS allows two-way text messaging, and has largely replaced Paging. Additional feature of some PABX systems which allows
See PABX
Early version of PDAs. See PDA.
A small mobile hand-held device that provides computing and information storage and retrieval capabilities for personal or business use, often for keeping schedule calendars and address book information handy.
Hand-held mobile device which not only acts as a mobile phone, but may also have features such as: email capable, organiser, diary, web enabled (either through WAP or HTML), SMS capable, etc. PDAs use QWERTY keyboards or other.
The times of day and days of the week, when communications traffic is expected to be high, when compared with other times.
Rates applied during Peak Periods. Normal rate plan pricing from Service Providers. Peak rates are only implicitly referred to through the use of terms such as Off Peak and Economy rates.
Use of a system (often involving multiplexors) which use less copper pairs than other systems to create the same telecommunications capacity. For instance, some pair gain systems are capable of delivering 45 phone lines over one copper pair - in theory, there is a gain of 44 pairs available for other use. Pair gain systems are extremely useful where buildings have no more available copper lines.
Typically this is a prepaid charge card, which allows calls to be made from most Landline services. Also called a Calling Card. Distinct from a TeleCard, which is not prepaid and will be billed back to the selected fixed service account.
The agreed service provided to a mobile or landline subscriber. Includes call rates, monthly access fees, included calls and special offers.
Utility for testing if a particular network destination is available on a network connection. It sends an ICMP (Internet Control Message Protocol) echo request and waits for a response. PING tests are commonly used to debug network connections. (A convenient analogy is from submarine use; where a submarine might send a sonar pulse (a ping) towards a target and wait for an echo. A sonar echo provides targeting information.)
Amalgamating the terms Pictures (PIX) and Element (EL). Images and video may be digitised and the smallest element is called a Pixel. Image resolution is defined as Pixels per inch.
Defined by billing method, Plan Types is a common usage term. Plans may be Prepaid or Post-paid. Prepaid mobile phone plans typically are casual plans, with higher rates and credit must be paid up-front. Buying of mobile usage credit can be done with credit card or cash: online, in shops or over the phone. Post-paid mobile accounts are typically mobile phone accounts under contract, with lower rates and are paid on invoicing of usage. Post-paid plans may be paid by direct debit, credit card or 'on account'.
Incoming call alert (also used for incoming SMS and email alerts) polyphonic ringtones produce a more `natural` sound than their predecessor monophonic ringtones. Polyphonic ringtones (often use MIDI files to) produce up to 24 simultaneous notes. This blending of notes creates a more natural sound.
Landlines: Location where a carrier provides connection into a local
exchange. Often in use in Australia, where Telstra commonly provides the Last
Mile connection (from the premises to the exchange) but another provider carries
the communications from the local exchange.
Internet Connection: Location
where a carrier provides connection into a local exchange. A PoP for dial-up
internet is described as a connection which is available within a local call
area. (See also MegaPoPs.) For broadband, a PoP is defined as a network node,
which is available in the local exchange.
Email term to denote the protocol for the retrieval of email from a server. POP3 denotes POP version three. See also IMAP - another email retrieval protocol.
Post-paid mobile phone contracts are typically mobile phone accounts under contract, with lower rates than their prepaid counterparts, and are paid on invoicing of usage. Post-paid plans may be paid by direct debit, credit card or `on account`. On account means payment is not automated, but rather is invoiced for payment.
Traditional switched telephone system using copper lines.
Protocol for connection to a TCP/IP network. The internet is a TCP/IP network.
Early protocol for creation of VPNs (Virtual Private Networks). Flawed security. Extended by introduction of L2TP, which incorporated Microsoft`s PPTP and Cisco`s L2FA technology.
See PRI.
A mobile handset feature which selects the possible words from the combination of keystrokes used. Alternatives may then be picked until the correct word is found. Example: When typing EARN, the keystrokes would be 3276, and the suggested word for those keystrokes may be FARM, then by scrolling through alternative words which use those keystrokes EARN can be selected. Most words are automatically suggested correctly the first time, which dramatically decreases the time needed to type a text message.
Prepaid mobile phone plans typically are casual plans, with higher rates and credit must be paid up-front. Buying of mobile usage credit can be done with credit card or cash: online, in shops or over the phone. (Technically, Prepaid is a contract. It is merely a rolling contract per month and the only penalty for leaving early might be the loss of remaining credits.) See also Post-paid Mobile Contracts.
The routing of domestic long distance calls, calls to mobiles and international calls through a default (preselected) service provider. Alternate providers may be selected on a call-by-call basis, through use of override codes. Often a customer will nominate their preselected service provider to also bill their local calls and service charges, called Rebilling.
Also called ISDN10/20/30, this is a conversion of a single copper pair (ordinary telephone line) into thirty 64 kbps `B` channels which may be used for voice or data. There is an additional 64kbps `D` data signal channel created also.
Service specification designed to ensure that persons diagnosed with life-threatening medical conditions, who depend on a reliable home telephone service, are able to call for assistance when needed. The timeframes for connecting a service or repairing a fault for a priority assistance customer is 24 hours in urban and rural areas and 48 hours in remote areas. Telstra, AAPT and Primus offer priority assistance services.
Network which is not accessible to unauthorised persons. An example of a private network is a company intranet, where users may access external networks (including the internet) but external users cannot access the company's intranet.
The rules which define communications formats. Without proper formatting, communications between computer systems would be meaningless.
Providing a telecommunications service to a customer upon request. Provisioning includes ordering, authorisation and implementation.
Server placed between a 'client' and a web server and represents itself to each end as being the other. It can be used in two ways. For the web server it can cache frequently accessed pages to reduce the web-server`s traffic. For security of the LAN clients it can present a single IP address to the Internet and prevent direct access to the rest of the LAN. [MicroUK]
Traditional switched telephone system using copper lines. PSTN services are used worldwide. Twisted pairs of copper telephone lines are connected from the customer premises to the local exchange. (These are also called local loops.) At the exchange the communications are electronically switched, in accordance with their destination. The network of these physical and switched connections are collectively called the Public Switched Telephone Network.
Also called Payphones, they are publicly available telephones which accept coins, debit cards or credit cards, and can be used for calling domestically and internationally. Call rates are high, compared to other telephones.
SIM Cards have a number of security features to prevent unauthorised use. One of these is the requirement to enter a PIN code (if enabled) into a phone when it is turned on. The PIN number is determined and set by the user of the SIM and only persons provided the PIN number are able to access the SIM. If the PIN code is entered incorrectly three times in succession, the phone will display "Enter PUK Code" or "SIM Blocked". The PUK (Personal Unblocking Key) Code is required to unblock the SIM to allow use. Each SIM has a unique 8 Digit PUK code.
Also called a Pin Unblocking Key. An 8-10 digit code used to unblock a SIM card which has been blocked. Service providers retain records of PUK codes.
The conversion of keystrokes on the handset into discrete pulses which represent dialled numbers. The direct current is interrupted for a certain number of intervals in accordance with the dialled number. This allows the carrier`s switching centre to connect the call to the chosen number. Pulse dialling has been superseded by tone dialling for efficiency reasons.
A fad technology, now passed in Australia. Allowed a users handset to be used as a 2-way radio with other compatible handsets. Talking was half-duplex: listening or talking, not both. (Mobiles and telephones are full-duplex: allowing talking and listening.) Superseded technology due to the availability of free intra account calling and free OnNet calling.
The service quality of a carrier`s network, including fault rates, connection times and call centre response times.
Generally, QoS in VoIP refers to the quality of a call connection, when compared to a traditional service. QoS is also a feature of modems and routers which enables IP traffic to be prioritised. Voice IP traffic is prioritised above all else, to reduce delays in the voice signals. A QoS router will greatly increase the quality of VoIP calls through an internal network. See VoIP also.
An english language keyboard (QWERTY are the first 6 letters on an english language keyboard). PDAs and other compact electronic devices often advertise whether they have a QWERTY keypad (QWERTY keyboard) as a feature, or use another type.
A telephone service provider takes over the collection and billing of services which they do not own or lease. Landlines: Where the service provider does not own or maintain the connection to the premises, rebill items are typically phone line rental and local call costs. Billable items, where the service may be typically owned or leased are: STD calls (long distance calls, NDD calls), Calls to Mobiles, and International Calls. Mobiles: Where the service provider is not a mobile carrier, rebill items are all charges which are not usage charges.
STD call (also called NDD - National Direct Dialled), which is not an intercapital call. Regional call rates and intercapital call rates have been phased out of common use, in favour of a single rate for any STD call.
One-way satellite broadband download link with an ISDN2 landline upload link. Capacities of upload speeds are being superseded by use of two-way satellite broadband.
Former government program aimed at providing greater access to affordable mobile telecommunications in areas without terrestrial services. Begun in 2001, ended 2004 or earlier.
Telephone user who is not a business customer.
A residential premises typically has only two phone lines installed. More phone lines may be installed at the cost of the customer.
Wireless communication technology using the radio band of the EMS (Electromagnetic Spectrum).
Sound alert to signal an incoming alert or message. See also Monophonic Ringtones and Polyphonic Ringtones. Not to be confused with a Ringing Tone, above.
Roaming refers to the ability of a wireless user to move freely, or "roam", within a building, campus or large complex while maintaining an unbroken wireless connection to the wireless local are network (WLAN). This is achieved by using a number of strategically positioned access points. As a user moves beyond the range of one access point, they are automatically handed over to the next one.
The agreement between two wireless carriers. The agreement defines roaming service capabilities and the charging structure for roaming service.
Device which directs data packet transfers along its available network paths. It examines the destination of a data packet and determines the most appropriate network point to which a data packet should be sent next. Determination of the best routing path is aided by network information received and stored by the router. A router may be a hardware or software (less common) device.
Recorded voice announcement- this is a pre-recorded announcement on the network indicating customers options, for example "telcoinabox regrets the number you have dialled is not contactable" "You cannot make outgoing calls. Please purchase a re-charge card and Dial 555" (Ding Dong) That number is not listed
Communications platform in orbit around the earth. These satellites send and receive communications signals. Satellites are very useful for their enormous coverage capabilities. There are three types, found at various heights above the earth: LEO (Low Earth Orbit, MEO (Medium Earth Orbit) and GEO (Geosynchronous Earth Orbit).
Internet connection using a satellite communications link. Two-way satellite broadband uses a satellite download link and upload link. One-way satellite broadband uses a satellite download link and a landline upload link (usually an ISDN2). Satellite broadband setup charges and running costs were subsidised in regional and rural areas through the HiBIS scheme, and are now subsidised using the Broadband Connect scheme.
Mobile phones which operate from satellites rather than land-based base stations. Coverage in remote areas is the primary use of these services, since usage costs are typically considered expensive. Also called Sat Phones. Sat Phones are often kept for emergency use in remote areas.
The size of the mobile phone or PDA handset`s screen area.
Symmetric Digital Subscriber Line (SDSL) is a Digital Subscriber Line (DSL) The main difference between ADSL and SDSL is that SDSL has the same upstream data transfer rate as downstream (symmetrical), whereas ADSL always has smaller upstream bandwidth (asymmetrical).
Also called Symmetric DSL. Download and upload speeds match, unlike ADSL. Operation is over a single copper pair, like ADSL, unlike HDSL. Traditional voice communications are unavailable, unlike ADSL, but SDSL is becoming popular for VoIP communications.
Computer hardware and software combined to `serve` information requests to its clients (PCs). Information might be data, files, emails, webpages, or other network services from client computers.
The physical address where the services are connected. A Billing Address may differ from the service address.
Monthly charge from a provider for provision of service. Call charges are additional to this charge. See also Access Fee.
The contract between a mobile service provider and customer. The `service` being supplied is connection and access to a telecommunications network. The service plan should describe all rates, charges and fees.
A company which provides telecommunications connection and service to a customer. The telecommunications service provider may be the actual carrier or a reseller of those services.
Prescribed terms and conditions which accompany a telecommunications service offer. Contains details of the service provider`s required conduct and a customer`s rights and obligations.
A SmartCard used (for mobile phones) to hold GSM encrypted security information and user information. The card holds the user`s phone number, PIN number, some or all phonebook contents and SMSs.
Switching telecommunications service provider without the customer`s knowledge or permission. This action is reversible and has been largely curtailed in Australia.
A government-run distribution portal for 1800, 13 or 1300 numbers. Often a smart number spells a mnemonic word. (eg. 1800-746-637 spells 1800-PHONES). Here are some websites which allow conversions of numbers into possible words:
Telstra product which enables landlines to have up to three distinct ringtones. By nominating up to 15 numbers per ring tone, customers can know which group a caller belongs to.
Communication of alphanumeric text messages from one mobile handset to another. (PC-to-SMS and email-to-SMS services are also available.)
SMTP - Simple Mail Transfer Protocol TCP/IP based protocol used to transfer e-mail messages over the internet. Often messages are finally retrieved from an email server using either POP or IMAP, because SMTP is not efficient at queuing emails.
Denotes a business run from a home or small office.
Unsolicited, bulk e-mails (or SMS messages). Also called Junk Emails.
Feature of a handset which dials a preprogrammed number automatically. Some handsets activate speed dial by use of a unique button on the handset, others use the prolonged holding of a button as their speed dial activation. Speed dialling is most often used for calling frequently used numbers. Emergency numbers may also be useful.
Telecommunications technique which segments a signal, sends the components over multiple frequencies, and then re-assembles the signal at the destination. Allows for higher data transmission rates and increased security capabilities.
The STD zone defined by a group of telephone numbers, for call charging purposes, that are not in an extended charging zone.
Rental charge for the provision of a handset. This is usually $2.95 per month. Higher rentals are often charged for a handset which is CND enabled (eg. with a digital display).
Often used when describing mobile handsets and cordless handsets. This is the time a handset battery can maintain a standby status - without active use (making and receiving calls, accessing phonebooks, etc.).
Direct-dialled long distance call. Also called NDD (National Direct Dialled) calls.
Method of encoding and sending data such that it can be processed as a continuous stream. Streaming is used especially over the internet, where audio and video files may be played without the need to download the file fully first. Instead, the download can proceed while the file is being viewed.
The copper lines between a customer premises and the local exchange. A Subscriber Loop describes the same. These lines are also called `twisted copper pairs` and can be thought of as a copper `loop` - one line to the premises and another line back to the exchange. Other names are PSTN line, telephone line, copper pair, standard telephone service line, POTS, etc.
See Slamming
Selects communication channels between users. Switches are faster than Routers (which are more autonomous). Electronic switches are used in telephone exchanges - hence the term PSTN (Public Switched Telephone Network).
A dedicated phone connection supporting data rates of 1.544Mbits per second; consisting of 24 channels, operating at 64Kbits per second. Each channel can carry voice or data traffic.
Often used when describing mobile handsets and cordless handsets. This is the time a handset battery can maintain an active status (making and receiving calls, accessing phonebooks, etc.).
Total Business Connect
IP controls the data, TCP organises the transmission of the data and its assembly at the destination. Together TCP/IP control the movement of data across the internet.
Splitting of customers` communications into varied frequencies and into different timeslots. Multiplexing of multiple signals onto a single channel on a single frequency. Used for GSM and some CDMA technologies.
Amalgamating the terms: TELephone and COmpany, a Telco is a telecommunications service provider or wholesaler. To operate in Australia, a telecommunications company must be registered with the TIO as a telecommunications provider. As of 2007, there are over 300 registered telephony providers and 800 ISPs.
Phone call where three or more parties are connected by a audio telecommunications link. Also called Conference Calls. (Videoconferencing is sometimes called teleconferencing, but is defined separately here for clarity.)
Fee applicable when a party to a contract terminates that contract. Generally this is the outstanding minimum amount agreed to in the contract. Usually this means the minimum monthly commitment multiplied by the remaining months, but sometimes an additional fee is nominated in the contract also. Also called a cancellation fee or a contract cancellation fee.
Independent body for complaint resolution and arbitration from customers of telecommunications service providers. The TIO also manages complaints relating to some ACIF Codes.
Independent regulatory body which applies a Code of Practice to 190 premium rate service numbers and the industry surrounding them. See their website: www.TISSC.com.au for more information. Or call the complaints hotline on: 1300 139 955.
Routing of incoming calls to selected destinations based on the current time of day. Most often used by call centres to direct call traffic according to economic reasoning.
Charges beyond any Flagfall, connection fee or minimum call charges. These
are usually per minute charges, billed in 1 second increments. The Toll is the
charge applied according to the duration of the call. See also
Toll-Free.
Local charging zone. Calls are toll-free because they have no charge in accordance with the duration of the call. See also, Toll Calling Charges, above.
13, 1300 and 1800 services. They are defined as toll-free because the caller is not charged dependent on the duration of the call. 13 and 1300 numbers do attract a Flagfall charge, but no toll. 1800 numbers do not attract any charges and are sometimes called Freecall Numbers.
Also called DTMF (Dual-Tone Multi-Frequency), is the conversion of keystrokes on the handset into discrete tones; one tone for each number dialled. This allows the carrier`s switching centre to connect the call to the chosen number. DTMF can also be used to interact with telephone systems such as telephone banking. Tone dialling has superseded Pulse dialling because it is more efficient and user friendly.
Minimum cost of a contract. Minimum monthly commitment multiplied by the
remaining months. This amount does not include any additional penalties which
may arise from early termination of the contract. See also
Early Termination
Fees.
Tone dialling handset. See tone dialling, above.
Amount of data or voice signals travelling through a communications channel at one time.
Transfer of a communications signal from one point to another.
Digging a narrow trench from the street (or pit) to a premises, to allow placement of phone lines or optic fibre. If a customer (especially a customer using residential premises) needs more phone lines into their premises, they may be asked to pay the costs of trenching. Notes: The customer also takes on the responsibility of informing the Telco when the trench is ready to accept the new lines, and the customer may take on the responsibility of backfilling the trench after placement of the new phone lines. It is important to note that the company who provides the trenching service is not affiliated with the telecommunications carrier, and that the customer is responsible for coordination between the two.
Typical term for STD calling. The term trunk is used here to denote that the call has gone over a long distance line (between exchanges) before being terminated.
The main connections between exchanges. Previous usage was intended to denote connections between exchanges which are located a long way apart - giving rise to the term STD, which denotes a long distance call.
Equipment used for communication with people who are deaf or who have a hearing, speech or communication impairment. A device, which attaches to a telephone handset, allowing deaf people to communicate by typing messages to each other. Also called a TDD.
Twisted copper pairs (or Copper Pairs) are the physical connections of PSTN lines, between premises and exchange. Subsequent to this, ISDN2 (BRI), ISDN 10/20/30 (PRI) and ULLs all use a single copper pair for transport of signal. Also called a Subscriber Line or Local Loop.
Internet connection using a satellite for both the download and upload links.
A dedicated copper pair from the MDF at the customer`s premises to a MUX, or similar, in the local exchange.
Alternate name for 3G services. (The transmission standard is WCDMA.)
A call to a `local` number (by definition, contained within the same area code or billing area), which is charged at a flat rate. Calls over the PSTN network are untimed local calls. (The introduction of ISDN services by Telstra allows for charging of local calls on those services.)
Network connection terminology used to represent a link to a higher part of a network.
A UPS is used as a backup supply of AC voltage. These discretionary supplies are most often used only for essential services. (DC battery supplies are commonly used in telephone systems.)
Short for Universal Serial Bus [connect the computer to external memory and peripherals], a USB is an external bus standard that allows the transfer of data at rates up to 12 Mbits per second and USB2 480Mbits per second. A USB port is used to connect peripheral devices, such as mice, printers and keyboards among others, to your computer.USB is an external interface standard, or connector, for communication between a computer and external peripherals and devices. USB is intended to replace existing serial ports, parallel ports, keyboard and monitor connectors and can be used with keyboards, mice, monitors, printers and removable hard drives. USB works at 1.5 and 12 Mbps (Megabits per second) with specific consideration for low cost peripherals. USB 2.0, sometimes referred to as `Hi-Speed USB`, is a much faster enhanced version - working at 480 Mbps.
The obligation under the Telecommunications Act 1999 to ensure that standard telephone services, payphones and prescribed carriage services are reasonably accessible to all Australians on an equitable basis, wherever they reside or carry on business.
A carrier or Carriage Service Provider responsible for fulfilling the Universal Service Obligation (USO).
Telecommunications where three or more parties are connected by a video telecommunications link. Also called a Video Conference. (Videoconferencing is sometimes called teleconferencing, but is defined separately here for clarity.)
Provision of voice communications over a DSL (Digital Subscriber Line) connection. Sometimes referred to as `Direct Connection` to a service provider`s network, via use of a ULL. Typically this connection can also supply a high-speed internet connection simultaneously.
See VoIP
A recorded message service where callers may be diverted. The caller is charged as though they are connected to the number called. For mobile services, the called party may also be charged. (See also Message Bank.) For landlines, voice mail may be provided by the service provider as a virtual service, through a PABX voicemail facility, or through an answering machine. For mobiles, voicemail is applied by the service provider or the carrier.
Part of the voicemail system where a users messages are kept and managed. This may refer to a PABX voicemail system or to a mobile phone`s voicemail facility.
Voice over Internet Protocol (VoIP) also named IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband is the routing of voice conversations over the Internet or through any other IP-based network.
Is the transmission of telephone calls over a data connection. Often perceived as voice-over-internet, several types of `managed` VoIP exist. Internet Calling is therefore a mere subset of VoIP. VoIP over internet often has severe limiting quality issues, due mainly to packet delays and packet losses. The quality issues can be decreased by use of an appropriate internet connection, use of a Qos Router, use of a quality VoIP service provider and use of appropriate hardware. See QoS Router (Quality of Service) also.
A virtual private network, or VPN, uses the Internet to connect users to their work or personal networks or servers through a secure `tunnel`. This means you can connect to your office network securely wherever there`s access to the Internet. For example, you could set up a VPN at any one of the hundreds of Hotspots located in airports, hotels and conference centres around the UK and the rest of Europe.
A secure network connection between users of differing LANs. A VPN may
be
constructed over private or public IP networks (such as the internet). VPNs are
becoming an essential tool for mobile employees, and for employees wishing to
work from home.
Data network where the distance between units prohibits the use of a LAN (Local Area Network) solution. WANs are high-speed, long-distance technologies to connect nodes of the network.
Set of protocols which enable mobile devices to access online content. WAP will be extended and superseded by the introduction of 3G technology into the online content market space.
The 3G wireless communications standard which evolved from CDMA. Also called UMTS.
The global network of servers on the internet, which allow access to html and other resources. The web uses the http protocol. Also called www and the World Wide Web.
A user interface for interaction on the web. The web browser fetches html and other documents from web servers and displays them for the user.
A computer connected to the internet that stores webpages and other files. These HTML documents and other files can be retrieved using a Web browser.
Wi-Fi is a non-profit organization created to provide an interoperability certification for Wireless LAN products based on the 802.11 standard.
Specified as 802.11b by the IEEE (Institute of Electrical and Electronics Engineers), Wi-Fi is wireless technology for creating networks up to around 100m, at 2.4 GHz. Wi-Fi is used to create LANs without the physical connections.
Transmission medium which is not land-based. Refers to the parts of the EMR spectrum which can be effectively used for telecommunications transmission. RF, IR, FM, AM, UV and microwave are all used for telecommunications.
Broadband services which are non land-based (and non satellite-based).
Wireless Local Area Networks or WLANs provide cable-free connection between notebooks, desktop PCs, printers, PDAs and your office network via wireless access points. This provides a simple way of expanding your network (and your business) without the hassle and expense of installing additional cabling.
Data encryption specification for Wi-Fi networks. Higher security than WEP. It improves on WEP by using dynamic keys, EAP (Extensible Authentication Protocol) to secure network access, and an encryption method called Temporal Key Integrity Protocol (TKIP).
Information and communication network using the Internet to access hypertext documents. Hypertext documents (often webpages) contain text, images, video and other hypertext items.
Collective name for the various classes of digital subscriber lines. ADSL, SDSL and SHDSL (and the outmoded HDSL) are collectively referred to as xDSL products. See DSL.
