Abstract
Abstract A distributing frame, for telecommunications systems, comprises an upright hollow member, on the front of which are mounted a number of shelf members, spaced vertically, one above the other. Modules, containing connectors are mounted on the fronts of the shelf members, usually in pairs, a pair on each shelf member, the modules side-by-side. Further modules are mounted on the back of the hollow member, again usually in vertically spaced pairs. Access to the modules is provided from the interior of the hollow member. A number of such frames can be mounted side-by-side and the tops of the shelf members form continuous shelves for carrying conductors. In an arrangement of a plurality of frames side-by-side, the front is referred to as the horizontal side, while the back is referred to as the vertical side.
