This technical report defines a profile that selects the features and options of certain standards that are required to operate streaming devices and medium changers in a Public arbitrated loop environment. Devices that operate in a public arbitrated loop environment are by definition capable of operating in a Private arbitrated loop environment. The primary objective of this technical report is the precise definition of those options so that devices conforming with this profile are guaranteed to operate. A second objective of this technical report is to simplify implementations and their associated documentation, testing, and support requirements. This technical report prohibits and requires both mandatory and optional features of the referenced standards to meet these objectives.
