Abstract

An automated distribution frame is disclosed for connecting a plurality of subscriber loops to a plurality of office equipment lines, the automated distribution frame comprising an overflow device and a plurality of switch arrays, each switch array comprising a corresponding plurality of inputs and a corresponding plurality of outputs, wherein a first part of the corresponding plurality of inputs is connected to the overflow device and a second part of the corresponding plurality of inputs of the switch array is connected to at least one corresponding subscriber loop of the plurality of subscriber loops and wherein a first part of the corresponding plurality of outputs of the switch array is connected to the overflow device while a second part of the corresponding plurality of outputs of the switch array is connected to at least one selected office equipment line of the plurality of office equipment lines. The overflow device is used for rerouting traffic from a given switch array to at least one other switch array if a number of services required by customers of the plurality of subscriber loops exceeds a number of services of the plurality of office equipment lines available at the given switch array.
