Which command should be used when a communication line is excessively busy?

The command "Busy" is used to indicate that a communication line is excessively busy and cannot accommodate additional transmissions at that moment. This term is commonly recognized in communication protocols to signal that operators should refrain from attempting to transmit further until the line becomes available.

In the context of radio communication or dispatch systems, using the "Busy" command effectively prevents multiple parties from trying to communicate simultaneously on a congested channel, which could lead to confusion or missed messages. It allows operators to maintain a clear line of communication by ensuring that only essential transmissions occur during peak times, thereby enhancing the overall efficiency of operations.

Understanding this command and its application is critical for effective communication in environments where coordination and timely responses are necessary, such as in law enforcement or emergency services.
