A modular interfacing assembly for providing termination connections between customer termination leads and input-output signal pins of a printed circuit card cage assembly is disclosed. The assembly consists of a rotatable frame having multiple interface boards mounted thereon. Each interface board provides for a certain number of terminations. A plurality of termination blocks containing termination pins suitable for attaching the customer termination leads to is mounted to the interface boards. The termination blocks, once installed onto the interface boards, cooperate with a portion of the board to provide a supporting channel for the customer termination leads. Also, contained on the interface boards are any special interface circuits, such as balancing resistors, that are required between the customer termination units and the input-output signal sources. Interconnecting each interface boards to the input-output signal pins is a set of interconnect cables which consist of a plug-connector arrangement at the interface boards. These cables contain the appropriate wire size and type for making the electrical connections to the input-output pins at the interconnect cable end opposite the end having the plug.
