What is expected when using the term "OVER" in communication?

When the term "OVER" is used in communication, it signifies that the speaker has completed their transmission and is expecting a response from the recipient. This is a crucial part of effective communication, especially in a dispatching context, as it ensures that both parties understand it is the recipient's turn to speak or reply. The use of "OVER" helps to prevent confusion and miscommunication, making clear that one party has finished their message and is awaiting further interaction.

In contrast, the other terms do not fulfill this expectation. Indicating that the channel is busy, clarifying the previous transmission, or suggesting a frequency change involve different communication protocols and would typically utilize different terminology. Therefore, recognizing "OVER" as a prompt for a required response aligns perfectly with standardized communication practices.
