A new automated main distributing frame system using robot

Abstract

A new automated main distributing frame (MDF) system was developed to reduce the metallic-MDF operation costs in communication networks. In this automated MDF (AMDF) system, a robot inserts connecting-pins into the crosspoint holes of matrix-boards. The jumpering and the route-setting for line testing can be completed within 3 min and 1 min, respectively. The AMDF system provides approximately 2000 office equipment cable terminals. Parallel installation of the AMDF systems allows construction of larger MDF systems. Three new technologies, high-density matrix boards, precision pin-handling, and high-reliability system control, reduce costs and secure reliability. Test results of the prototype AMDF system confirm the effectiveness of these new technologies.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
