TETM14-20C electrical components refer to the aggregate of service equipment provided to a specific group of traffic sources, such as trunk lines, switching devices, and control systems. The fundamental research content of traffic theory is the study of the relationship between traffic volume, call loss, and trunk group capacity; therefore, the trunk group is an important basic concept in traffic theory. A traffic source is the service object of a trunk group, usually referring to user equipment; broadly speaking, the upper-level device is the traffic source for the lower-level device. In telephone communication, a traffic source is also called a call source. The number of service devices contained in a trunk group is called the trunk group capacity. Figure
