A printed circuit board assembly for coupling a plurality of surge protectors to multi-line communication cables includes a multi-layer printed circuit board, to which has been mounted at least two cable connectors, having multiple female sockets for receiving standard surge protector modules. The multi-layer printed circuit board includes traces on multiple layers in a manner that a unique signal path exists between each lead in each connector and a predetermined one of the plurality of sockets for receiving surge protector modules. The traces having a width and a copper content sufficient to carry large current surges from induced power signals, by way of example, from a lightning strike, without breaking down. |
