X.225

X.225 is a standard that defines how systems communicate in a network, specifically focusing on establishing, maintaining, and managing connections. It forms part of the OSI (Open Systems Interconnection) model, providing rules for data transmission in telecommunication networks. Essentially, X.225 ensures devices can reliably connect, verify each other, and exchange data efficiently. It includes protocols for initiating connections, handling errors, and closing sessions, enabling diverse network components to work together smoothly. This standard helps maintain organized, dependable communication across different systems and networks.
