Abstract
An apparatus and method for replacing circuit boards in a live communication system having an over-the-top ribbon cable data bus configuration. The ribbon cables are segmented and redirected between individual circuit boards and a backplane data bus. Each ribbon cable connects either directly to the backplane or to an interposer board coupled between the circuit board and the backplane. Isolation circuitry either on the backplane or on the interposer board isolates clock and data signals between the backplane and a circuit board selected for replacement.
