ABSTRACT:
A generic process for combining the support of multiple formats and protocols (FAPs) for simultaneous communication between a controller and an attached device over the same port is described. The transmission medium between the two units is a two-wire type cable, i.e., twisted pair, coaxial, etc., generically referred to as "Coax". The controller and the attached device each support their own collection of Coax FAPs, which may or may not be different. In accordance with the process, information is exchanged between the controller and the device identifying the particular Coax FAPs each respective unit supports and a set of Coax FAPs common to the controller and the device is identified. A communication buffer common to the controller and the device is configured for supporting the set of common Coax FAPs. Each Coax FAP may be independently enabled or disabled.
