Which of the following frequencies are used for digital communicator handshakes?

The frequencies used for digital communicator handshakes are critical in ensuring that alarm systems can communicate effectively over telephone lines or other transmission mediums.

The selection that includes 1400 Hz, 2300 Hz, and a dual tone encompasses the standard frequencies used in digital communicators. Each of these frequencies plays a specific role in signaling and synchronization between devices.

14100 Hz serves as a common tone to signal the start of communication, while 2300 Hz is often a response or an acknowledgment tone. The use of dual tone systems allows for more efficient communication, as multiple frequencies can ensure that signals are sent and received accurately, reducing the likelihood of errors that could occur with single-tone systems.

This combination of frequencies is widely adopted in alarm systems for establishing secure handshakes during the communication process, making it essential knowledge for anyone involved in or studying burglar alarm system operations in Utah.
