This American National Standard specifies limitations and requirements that may be accepted within the Scheduled Transfer (ST) protocol (ANSI NCITS 337-2000) in order to facilitate interoperability for reliable data transports.

This profile is an interoperability specification. The profile provides implementation guidelines for systems manufacturers, system integrators, component manufacturers, and users seeking to design and select interoperable ST peripherals, hosts, and components. This profile specifies which settings of the ST parameters and protocol options have been selected for interoperable implementation.

There should be no implication that this profile is suitable for all users or circumstances. Other mappings for the ST protocol are being developed and may be more suitable for a particular set of needs. Requirements may also force implementors to operate outside of any profile definition.

This profile is not a certification document; conformance can only be assured by actual testing of interoperability with independently developed products that have the same profile.

This profile prohibits or requires features that are optional, and prohibits the use of some non-optional features in the referenced ANSI standard. Internal characteristics of conforming implementations are not defined by this standard.
