摘要：An arrangement of plural filter circuits on a single card, and interconnection andmouthing of numerous cards on a single rack to facilitate maintenance, is provided foruse in a telco. In each of the filter circuits, there is a first plurality of inductors connectedin series in a first leg of a balanced line configuration of filter, a second plurality of
inductors connected in series in a second leg of the balanced line configuration of filter,and a plurality of capacitors connected as cross branches between terminals of theinductors. A substrate supports the capacitors and the inductors, wherein each of theinductors is a toroidally wound inductor comprising a toroidal core of magnetic
saturation inhibiting material. The saturation inhibiting core material allows reduction insize of a cross-sectional dimension of the core to approximately the cross-sectionaldimension of one of the capacitors. For telco equipment, a set of connectors is mountedin a back plane of an enclosure for receiving the cards, and a plurality of bypass switchesare disposed in the set of connectors for bypassing voice signals around correspondingones of the cards. The bypass switches are placed in a state of conduction upon removalof a corresponding one of the cards from the set of connectors.
