Digital Subscriber Line (DSL)
Digital subscriber lines carry data at high speeds over standard copper telephone wires. DSL users can receive voice and data simultaneously so there is no need for a separate phone line.
Bandwidth
Bandwidth is the rate at which digital information (data) can be transferred. A standard measurement is bits-per-second (bps) or kilobits per second (kbps).
Broadband
Broadband is a form of data transmission where a single medium (wire) can carry different types of information simultaneously. For example; a single cable may provide internet access, telephone and cable television.
Downstream / Upstream
The direction in which data moves along the fibre. Downstream refers to data being sent to your household, and upstream the data you send to others.
Optical Fibre
Optical fibre refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic wire or fibre. Optical fibre carries much more information than conventional copper wire and is in general not subject to electromagnetic interference and the need to retransmit signals.
Voice over Internet Protocol (VoIP)
Voice over Internet Protocol is a technology that allows telephone calls to be made over computer networks, like the internet. It converts analogue voice signals into digital packets and supports real-time two-way transmission of conversations.
