<p><P>PROBLEM TO BE SOLVED: To provide a connection box for a small-scale PBX which allows anyone to carry out wiring by himself/herself without requiring a qualified person if only a modular jack connected to a telephone line is provided, thereby allowing a reduction in construction cost, eliminating the necessity for adjustment of the date and time of execution, and thus accelerating introduction of the small-scale PBX. <P>SOLUTION: The connection box for a small-scale PBX comprises: a number of outside line modular jacks corresponding to the number of outside lines connectable to a main device of the small-scale PBX; a number of telephone set modular jacks corresponding to the number of extension telephone sets connectable to the main device; a FAX modular jack for connecting a facsimile; and connection cords for connecting the respective modular jacks and the main device to each other. At positions near the respective modular jacks, there are provided instruction marks each made up of characters and/or an illustration indicating the destinations of connection to be connected to the respective modular jacks. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
