PROBLEM TO BE SOLVED: To obtain a single stage link structure of a main distributing frame for connecting a unit in a central office with a subscriber line in which a pass route can be formed and multiconnection can be made. SOLUTION: The single stage link structure of a main distributing frame comprises input lines for inputting signals from subscriber lines to an MDF, a first matrix board and a second matrix board each having terminals arranged in matrix form, and output lines for outputting signals to an exchange. Rows of respective matrix boards are interconnected, the input line is connected with an arbitrary terminal of the first matrix board, that arbitrary terminal is connected with a terminal of the second matrix board which is then connected with an output terminal, thus forming a pass route between the subscriber line and the exchange.
