PURPOSE:To attain miniaturization and to reduce an occupied area by mounting integrally receptacles of a protector module and various terminal blocks. CONSTITUTION:The 1st wall face 1092 is taken as an upper face and the 3rd wall face 1098 is taken as a lower face to an MDF frame 10 in the 1st-3rd terminal blocks 109-206. The intra-office wirings such as intra-office cables, outside cables and jumper cables conducted by a manufacture after installation are conducted by plug-in from the front face of the assembly to the 1st and 2nd board assemblies 100 and 200 of the MDF board 30. Further, the MDF board 30 where the 1st and 3rd terminal blocks 109-206 and the receptacle 205 of a protector module 40 are assembled integrally is used as one unit and mounted easily from one direction (front side) of the MDF frame 10, then the total wiring man-hours are saved and the site assembling man-hours are reduced.
