Method for connecting gigabit interface converters with serial identification capability into an active two-wire serial bus

A method for connecting an interface to a serial bus is provided comprising the steps of sensing at least one identification line for the interface, identifying an interface type from the at least one identification line, and switching the interface to or from a serial bus depending on the interface type identified. The at least one identification line specifies at least one serial type of interface and at least one non-serial type of interface. Preferably, the method further comprises the step of switching the interface off the serial bus based on a criteria.
