PURPOSE:To change the frame wiring into the intra-panel wiring and thus to reduce the production cost by setting the correspondence between the trunk frame and the network to 1-step and 2-level structure. CONSTITUTION:For trunk frame 10, the lowest step, for example, is made to correspond to 2 levels of 0 and 4 of the 4 switch elements of SWO, 1, 2 and 3 among the switch elements forming the network. Thus, each step features the similar mounting structure. The outgoing lines corresponding to 4 levels of 0, 4, 1 and 5 equivalent to 2 swtiches of switch element SWO and 1 is processed within the panel into which connector 0' is mounted. Thus, the wiring can be given at the production time as intra-panel wiring 30 before the panel is incorporated into the frame. |
