Method and device for line-switching of MEMS matrix and AMDF

A device for line-switching of micro electro-mechanical system (MEMS) matrix comprising:

• a MEMS matrix;
• and
• a plurality of switch apparatuses each provided on only one access line of the MEMS matrix and provided on only one port of the MEMS matrix;
• wherein said switch apparatus switches the current introduced into the MEMS matrix before and after the switching of a switch unit in the MEMS matrix is performed.

An automated main distribution frame (AMDF) system for line-switching, the AMDF system comprising:

• a micro electro-mechanical system (MEMS) matrix connected to device cables, user cables, a switching control part, and protection relays,
• wherein the device cables each are configured to connect to a device in a communication network,
• wherein the user cables are configured to connect to user terminals in the communication network,
• wherein the switching control part is configured to control a switch unit in the MEMS matrix that performs wiring line switching between access lines,
• wherein the protection relays each connect to the switching control part and are mounted between the MEMS matrix and the device cables or between the MEMS matrix and the user cables,
• wherein the protection relays are controlled to cut off current introduced into the MEMS matrix before the switching control part controls the MEMS matrix to perform wiring line switching, and
• wherein the protection relays are configured to recover the current introduced into the MEMS matrix when the wiring line switching is finished.
