Call 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
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
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

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
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
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

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,
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
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
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
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
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.

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
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
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.

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.

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.

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

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

`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,

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

(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
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
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
Telstra product. Callers may use a non-connected (virtual) number to leave
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.

Occurs when normal operations of a carriage service provider are
significantly disrupted by circumstances beyond that carrier’s control.
Mobile Service Number- the number associated with your phone and account.
The CO (Central Office) that controls the activities in a mobile phone
network. A computerised system which maintains mobile calls, defines the current
base-station for all its mobile devices, coordinates handoffs, notes drop-outs
and provides billing information.
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
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

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
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
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
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
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
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
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
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
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
Traditional switched telephone system using copper lines.
Protocol for connection to a TCP/IP network. The internet is a TCP/IP
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.
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
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
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
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
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
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.

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
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

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
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.

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
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
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)
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.
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

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
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
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
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
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,
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

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
Typical term for STD calling. The term trunk is used here to denote that the

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
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
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.

sometimes called teleconferencing, but is defined separately here for
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.
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.

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
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
