scope:

This standard defines the protocol requirements of the Automation/Drive Interface - Transport Protocol to allow conforming ADI SCSI devices to inter-operate. The objectives of ADT-2 are:

a) to provide a low cost interconnect method between an automation device and the data transfer devices that reside within the media changer (see SMC-3). To standardize this interface such that different disk drives, tape drives, optical media drives, and other SCSI devices may be added to conforming media changers without requiring modifications to generic system hardware; and

b) to provide for the addition of special features and functions through the use of vendor-specific options, reserved areas are provided for future standardization.

The interface protocol includes provision for the connection of two SCSI ports. One of these ports is intended to be attached to a media changer device and operates as a SCSI initiator port or as both a SCSI initiator port and a SCSI target port. The other device is intended to be attached to a data transport type device (i.e. a disk drive, tape drive, or optical medium device) and operates as a SCSI target port or as both a SCSI initiator port and a SCSI target port

This standard defines the transport attributes of an input/output Automation/Drive Interface for interconnecting a conforming media changer device to a conforming data transport device.

The set of SCSI standards specifies the interfaces, functions, and operations necessary to ensure interoperability between conforming SCSI implementations. This standard is a functional description. Conforming implementations may employ any design technique that does not violate interoperability.
