ACCC

Australia Competition and Consumer Commission (ACCC).

AON

Active Optical Network – a general term that describes any network configuration in which Multiplexors (MUXs), either in a Central Office or a cabinet are used to connect multiple Optical Network Units (ONUs) via dark fibres. A Point to Point network is an AON with an emphasis on direct connection to each ONU, in which case each dark fibre provides a direct point-to-point physical connection between the MUX in a Central Office and each ONU.

Ultra-fast broadband. Broadband is a technology that allows data to be transmitted at high speeds between the internet or applications on computers in the ‘cloud’ and your computer or mobile phone. It allows a greater volume of data to be transmitted much more quickly than dial-up internet because it can handle a greater range of frequencies – or, in geek speak, a higher ‘bandwidth’. This is where the term ultrafast broadband comes from.
