Asymmetric Digital Subscriber Line is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional dial up modem can provide. It does this by utilizing frequencies that are not used by a voice telephone call.

It is called asymmetric because the download and upload speeds are not symmetrical (download is faster than upload).


ADSL2 adds new features and functionality targeted at improving performance and adds support for new applications and services. Among the changes are improvements in ADSL's data rate, an increase in the distance ADSL can reach from the local telephone exchange, dynamic data rate adaptation, better resistance to noise, diagnostics, and a stand-by mode to save power. ADSL2 also reduces the initialisation time from more than 10 seconds (as is required for ADSL) to less than 3 seconds.


ADSL2+ extends the capability of basic ADSL by doubling the number of downstream bits. The data rates can be as high as 24 Mbit/s downstream and 1 Mbit/s upstream depending on the distance from the digital equipment (DSLAM) to the customer's home. This doubles the downstream data rates of the previous ADSL2 standard of up to 12 Mbit/s, but like the previous standards will degrade from its peak bitrate after a certain distance.

ADSL Central Filters

ADSL Central Filters have the advantage that you need only one filter for all phone devices in the household.

They are extremely useful to …

  1. Remove "line noise" on the telephone line
  2. Increase internet speed
  3. Remove ADSL "noise" from alarm systems
  4. Remove unsightly inline filters

As this is a hard wired option it is not flexible during relocation of the ADSL modem / router so a licensed technician will need to re-configure the cabling.


An internet connection with a much larger capacity than dial-up or ISDN. Often referred to as a generic term used to describe fast internet access, regardless of weather it is Cable or ADSL.

CAT 5e

Short for Category 5 enhanced, CAT5e is a high performance cable that is mainly used for the transmission of data. It is designed for transmission speeds of up to 1 Gigabit per second.


Category 6 standard is designed for transmission speeds exceeding 1 Gigabit per second. Some CAT6 cable has a spline to increase separation between the pairs and to maintain the pair geometry to improve performance.

Using CAT6 cable with CAT5e connectors is classified as "CAT5e Channel". The performance will probably be somewhat better but no where near CAT6 requirements.

CAT6 is the 6th generation of twisted Ethernet cabling. CAT6 connectors are made to higher standards that help reduce noise caused by crosstalk and system noise.

CAT 6A - Category 6A Data cables

All Phoneworks technicians now carry Krone Cat 6a data cables and data jacks in their vehicles for people wanting high performance data networks.

Cat 6a cables are an improved version of Cat 6 data cables and enable better performance, particularly in the area of alien crosstalk or signal leakage, as compared to Cat 6 when tested.

Cat 6 cables are rated at 1 Gbp/s while Cat 6a can achieve up to 10 Gbp/s.

This is because it can transmit data at 500 MHz — twice that of Cat 6.

Our technicians have been fully trained on how to install all data cables, including Cat 6a which must be properly installed and terminated to meet specification standards.


Category 7 cable is a cable standard for Ethernet and other interconnect technologies that can be made to be compatible with traditional CAT5 and CAT6 Ethernet cable. CAT7 features even more strict specifications for crosstalk and system noise than CAT6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole.

The CAT7 cable standard has been created to allow 10 gigabit Ethernet over 100 m of copper cabling. The cable contains four twisted copper wire pairs, just like the earlier standards.

Customer Service Guarantees (CSGs)

This is a legislated service guarantee that the Telco's have to provide to their clients for the disruption of service to the phone line. In short, it is compensation for loss of service. For more information about CSGs please read ACMA's Customer Service Guarantee Standard 2000 (No.2) fact sheet.


Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). Ethernet was originally based on the idea of computers communicating over a shared cable acting as a broadcast transmission medium.

The common cable providing the communication channel was likened to the ether and it was from this reference that the name "Ethernet" was derived.


Integrated Service Digital Network is one of the oldest high-speed digital access methods for consumers and businesses to connect to the Internet. It was popular for faster internet access before broadband had been introduced.

Some companies still use ISDN for connection to their telephone systems. It allows some flexibility in obtaining consecutive telephone numbers.


Local Area Network is a computer network covering a small area, like a home or office.


Short for Main Distribution Frame is a telecommunications frame or box mounted in the customer's premises where the phone lines from the street are terminated/connected. Phone numbers may be "tagged" here with a card from the Telco provider. A private licensed technician can then identify the number and extend it to a workstation device or phone. Quite often the line is not tagged and the technician will either need to check the record book kept with the MDF or back-dial the number which activates an animated voice telling them the number associated with that particular line.

Naked DSL

Naked DSL is a broadband product offered by some Internet Service Providers that supply DSL over the phone line without a telephone number attached. There is no dial tone associated with this line as there normally is.

Network Boundary

The network boundary is the place where the legal responsibilities of the Telco's finish. Read more »»

Network Cabling

This is cabling using Ethernet or Data cabling to link computers. Often referred to as the LAN.

Telecommunications Industry Ombudsman

The Telecommunications Industry Ombudsman is a free and independent alternative dispute resolution scheme for small business and residential consumers in Australia with unresolved complaints about their telephone or internet services.


Very High Speed DSL is a DSL technology providing faster data transmission over a telephone line. These fast speeds mean that VDSL is capable of supporting new high bandwidth applications such as HDTV, as well as telephone services (Voice over IP) and general Internet access, over a single connection.


Second-generation VDSL2 systems can provide data rates exceeding 100 Mbit/s simultaneously in both the upstream and downstream directions. The maximum available bit rate is achieved at a range of about 300 meters.


Wide Area Network is a computer network that covers a broad area. The largest and most well-known example of a WAN is the Internet.
