When describing telecommunication systems, it is often important to note whether it is a simplex, half-duplex, or a full duplex communication.
In trying to explain this variable or attribute, I couldn't find an appropriate word to describe these types of communications.
Is there a common term that engineers use to describe the 'simplexity' or 'duplexity' of a communication scheme?
I'm thinking along the lines of transmission direction or transmission type, but both of these descriptions suffer from being potentially incorrect or too vague. It seems there isn't yet a practical, nor concise, way of explaining this communication attribute.
