Each Harness Has Its Own Power

According to the different structure, the wiring harness can be divided into full availability harness, partial availability harness and link system. If the service mode is different, it can be divided into loss wiring harness and waiting wiring harness. According to the number of load sources, it can be divided into infinite load source harness and finite load source harness. In this telecommunication system, the equipment which can be directly used for communication between users is mostly the full utilization link system with infinite load source loss, while the equipment which is used to control the connection process of communication equipment is mostly the full utilization system with infinite load source waiting. When the number of load sources is not large relative to the capacity of the harness, the full availability system or partial availability system with finite load sources is generally adopted.
