Wire equipment

Wiring harnesses provide a whole set of service equipment, such as relay lines, switching devices, control systems, etc., for a given load source group. The basic research content of traffic theory is to study the relationship among traffic volume, call loss and wiring harness capacity. Wire harness is an important basic concept in traffic theory.

Load source is the service object of wire harness, which usually refers to the user device. Broadly speaking, the upper level of equipment is the next level of equipment load source. In telephone communication, the load source is also called the telephone source, and the number of service devices contained in the wire harness is called the capacity of the wire harness. Figure 1 is a schematic diagram of the wire harness. The harness has a capacity of V and serves N load sources. Any load source that makes a call may occupy one of the idle service devices in the wire harness
