Understanding carrier standards

The term carrier standards refers to standards that have been agreed upon for the various different carrier technologies. These standards cover a whole range of areas, including coding mechanisms, modulation, voltages, and physical attributes. However, for the exam we only need to have a high-level understanding.

We will now look at some of the common individual carrier standards.
