COSMOS was introduced in the 1970s after MDFs were found to be congested in large urban telephone exchanges. It assigns terminals so jumpers need not be so long, thus leaving more space on the shelves. COSMOS also converts customer service orders into printed work orders for staff who connect the jumpers.
