Abstract
A digital bus backplane is disclosed that has interface circuitry located on the backplane. The backplane includes a backplane circuit board containing signal bus lines each operable for conducting electrical signals, several connectors each physically coupled to the backplane circuit board and each operable for electrically contacting the signal pins of a daughter board inserted into the connector, and many transceivers each physically coupled to the backplane circuit board and each electrically connected between one of the contact pins of a connector and one of the signal bus lines, where each transceiver is operable for relaying electrical signals between a daughter board and a signal bus line.
