Abstract :
The concentrator to be described has individually packaged circuits for each line, which may be distributed along the cable and operated by circuits in the central office. It permits concentration of a multiplicity of lines to relatively few trunks. A so-called number group control is used to effect the operations at the remote packaged units. This can become the first stage in a normal switching system.
