Out-Of-Band Signaling refers to a method of communication where control signals are sent over a separate channel from the main data transmission. This approach enhances security and reliability, as it allows for the management of network devices without interfering with the primary data flow. It is commonly used in telecommunications and computer networks. In telecommunications, Out-Of-Band Signaling can help in tasks like call setup and teardown, ensuring that these processes do not disrupt ongoing conversations. This technique is also beneficial in network management, allowing administrators to access devices remotely and perform necessary configurations or troubleshooting without affecting user traffic.
