Bel Power electrical components, German Bel Power models, Bel Power prices
Bel Power electrical components refer to the aggregate of service equipment provided for a specific group of traffic sources, such as trunk lines, switching devices, and control systems. The fundamental subject of traffic theory is the relationship between traffic volume, call loss, and bundle capacity; therefore, the bundle is a key basic concept in traffic theory. A traffic source is the object served by the bundle, typically referring to user equipment; in a broader sense, upstream equipment serves as the traffic source for downstream equipment. In telephone communications, a traffic source is also called a call source. The number of service devices contained in a bundle is called the bundle capacity, see Figure 1.
