Single sided DSX frame

摘要

A single sided telephone frame particularly suited for DSX use utilizing a standard relay rack. In-plant equipment cables are interconnected to equipment blocks at an upper end of the frame. Below the equipment blocks are a group of jack panels located between groups of cross-connect block elements to maintain cable connections therebetween as short as possible. Connections between groups of cross-connect blocks to the jack panel elements, and from the jack panel elements to the equipment block elements are principally through a single vertical trough along one side of the frame, thereby permitting maximum space utilization. Each of the elements includes a metallic enclosure having members forming segments of the trough which are aligned to vertical congruency upon assembly upon the frame.
