Classification and application of common wiring harnesses?

Communication harness manufacturers say that the telecommunication system, directly used for communication between users of the equipment, more than unlimited load source loss system full utilization of the link system, and for the control of communication equipment for the process of connecting the equipment, more than unlimited load source waiting system full utilization of the system. When the number of load sources is not very large in relation to the harness capacity, a limited load source full utilization system or a partial utilization system is generally to be used. Based on the call behavior of the load source, i.e., whether the user makes a new call attempt after a failed call, the harness can be classified as a repetitive call system or a non-repetitive call system. Actual communication systems have repeated calls, and non-repeating call systems are an approximation of repeating call systems.

Communication harness manufacturers call a fully utilized harness. A harness is called a fully utilized harness if any of the service devices (trunks or machine keys) in the harness can be used by any of the load sources in the group of load sources it serves. Partially Utilized Harness. If any of the load sources in the load source group can only use a portion of the equipment served by the harness, such a harness is called a partial utilization harness. A partial utilization harness divides a load source group into several subgroups, and the wires of the load group are connected to each other. The service load capacity of a partially utilized harness is lower than that of a fully utilized harness for the same harness capacity. Its service loading capacity or call loss rate is related to the utilization degree and the method of product reconnection. Under the condition of the same harness capacity and call loss rate, a good product duplex structure can improve the load capacity of the harness. The greater the utilization, the closer the efficiency of the harness is to that of a fully utilized harness.
