ABSTRACT:
A modular terminal comprising a frame, a data distribution chamber, a power distribution apparatus and plural functional units. The functional units are supported and oriented by the frame in such a way that each interconnects with the power distribution components. Functional units communicate via optical transmissions through the data distribution chamber. This allows a functional unit to be inserted, removed or moved from one frame location to another without special equipment or tools by unskilled personnel.
