Trunking is a telecommunications method that combines multiple signals into a single communication channel. This technique allows for more efficient use of bandwidth by enabling various types of data, such as voice and video, to travel over the same line. Trunking is commonly used in systems like telephone networks and computer networks to optimize resource usage. In a trunking system, a central point, known as a trunk, connects multiple endpoints, such as switches or routers. This setup reduces the number of physical connections needed, simplifying network management and reducing costs. Trunking is essential for modern communication systems, enhancing both performance and scalability.
