3 Definitions
baseband – the primary signal characteristic in a network where only one carrier frequency is used (Ethernet is an example of a baseband network).
broadband – a transmission system that combines multiple independent signals onto one cable.
cable – any or all of copper cable, fibre optic cable, and coaxial cable.
industry practice – those practices that competent practitioners within the industry recognise as current industry best practice.
