TAILIEUCHUNG - DSX-1 Digital Signal

Traditionally, as DSX frameworks grew, DSX chassis and the jumper rings associated with them were added one by one. Existing cross-connect jumpers had to be fed into the new jumper rings as the new chassis were installed. Jumper movement in any one direction was often restricted since jumper rings were not present at unequipped chassi positions. If jumpers were pulled too tightly across unequipped positions, feeding them into new rings was difficult if not impossible. Also, jumpers may have cut across corner as they transitioned from vertical to horizontal wireways | DSX-1 Digital Signal Cross-Connect Rack Framework and Accessories Seventh Edition . . . . . .
