Patent ID: 7783026

Claim:
A system for configuring a connection for a port in an electronic device, comprising: a removable interface circuit on a first printed circuit board (PCB) to process signals for said connection for said port; an interface circuit connection bus connecting to said interface circuit; a port connection bus connecting to said port; and a removable first wiring adapter interface for said interface circuit, providing a connection circuit connecting tracks in said interface connection bus to tracks in said port connection bus, said first wiring adapter comprising a second PCB; a connector located on said second PCB for connecting said adapter to a corresponding connector in said system; a set of connections to connect said port to a first set of tracks from said interface connection circuit to a first set of tracks in said port connection bus; and a signature circuit located on said second PCB to distinguish said wiring adapter from a second wiring adapter, wherein said port provides a physical connection for said electronic device to a network connection or a terminal; and said signature circuit is used to identify said first wiring adapter from said second wiring adapter for said interface circuit.
