Converging Technology any existing technologies that are integrated to provide a new service including convergence of any previously separately existing technologies that now share resources and interact with each other. CPE Customer Premise Equipment. Emerging technology any technology which is at the development stage, or in early stages of production and commercial use overseas, but is not yet used commercially in New Zealand. FOG Fibre Optic Grid. Industry practice those practices which competent practitioners within the industry recognise as current industry best practice. IP Internet Protocol. OTDR Optical Time Domain Reflectometer. POE power over ethernet. RJ45 Registered Jack The use of mathematics is not required except where calculation is specifically mentioned.
