Abstract: A line card shelf is disclosed. The line card shelf includes groups of line card receptacle connectors. Each receptacle connector has electrical contacts receiving corresponding line card contacts. Each group of receptacle connectors is coupled to at least two external connectors that terminate an inside or outside wiring cable bundle. Each receptacle in each group is connected to each external connector of the receptacle's group by a two-conductor signal path between a pair of electrical contacts in the receptacle and a unique pair of external electrical contacts in the external connector.
