Automated main distribution frame
Automated Main Distribution Frame (AMDF)(automated switching matrix, automated distribution frame, Loop Management System (LMS)), a technology to provide connectivity between subscriber- and office equipment lines in telecommunikation infrastructure, e.g. in central office main distribution frames.
As of today the connections (n-subscriber lines and m-office equipment lines)are established/removed manually using a drilled pair of copper wires (jumper).
The automated main distribution frame is providing, after a initial installation of all relevant subscriber- and office equipment lines, remote controlled and localy performed connectivity by switching via the switching matrix of an AMDF.
Advantages of automated main distribution frame is reduced switching time, reduced errors in execution and documentation, no truck-rolls for each subscriber connection to be established, reduction of operational expenditures (OPEX).
