Specifies Twisted Pair Physical Layer Medium Dependent (TP-PMD) requirements for the Fibre Distributed Data Interface (FDDI). FDDI provides a high-bandwidth (100 Mbit/s) general-purpose interconnection among computers and peripheral equipment using fibre optics and twisted pair as the transmission medium. FDDI can be configured to support a sustained data transfer rate of at least 80 Mbit/s (10 Mbyte/s). It may not meet the response time requirements of all unbuffered high-speed devices. FDDI provides connectivity for many nodes distributed over distances of several kilometers in extent. Default values for FDDI were calculated on the basis of 1 000 physical links and a total fibre path length of 200 km (typically corresponding to 500 nodes and 100 km of dual fibre cable).

Describes in detail the basic Fibre Channel services introduced in American National Standard for Information Technology - Fibre Channel - Physical and Signaling Interface (FC-PH), ANSI X3.230-1994. In addition, this document describes any ancillary functions and services required to support the Fibre Channel services. Services described include name services, time services, alias services, SNMP services, and security key distribution. This standard replaces ANSI X3.288-1996.

100-SM-LC-L describes an enhancement to American National Standard for Information Technology - Fibre Channel - Physical and Signaling Interface (FC-PH), ANSI X3.230-1994, to American National Standard for Information Technology - Fibre Channel - Physical and Signalling Interface-2 (FC-PH-2) ANSI X3.297-1997, and to American National Standard for Information Technology - Fibre Channel - Physical and Signalling Interface-3 (FC-PH-3), ANSI X3.303-1998, and is an addendum to the FC-PH, FC-PH-2, and FC-PH-3 documents. This document is an extension to the FC-PH, FC-PH-2, and FC-PH-3 standards and describes a low-cost 10-km optical interface.

Defines the mechanical, electrical, timing, and protocol requirements of the SCSI parallel interface to allow conforming SCSI devices to inter-operate. The SCSI parallel interface is a local I/O bus that may be operated over a wide range of transfer rates. This standard was originally listed for public review in the March 10, 2000 issue of Standards Action. It is being resubmitted due to substantive changes to the text.

Describes a communication interface between a channel and I/O control units that utilize the Single-Byte Command Code Sets (SBCCS) as implemented in a wide range of data processing systems. It employs information formats and signaling protocols that provide a uniform means for communicating with various types of I/O control units, facilitating a high bandwidth, high performance, and long distance information exchange environment. The signaling protocols and information ex-changes are defined at a layer (FC-4) to compatibly utilize the link services and other functions pro-vided by the ANSI Fibre Channel Physical and Signaling Interface (FC-PH) architecture (ANSI X3.230- 1994, reference [1]). This FC-4 Upper Level Protocol is referred to as the Fibre Channel-Single-Byte-2 Command Code Sets Mapping Protocol (or for brevity, SB-2).

Defines the SCSI commands that are mandatory and optional for all SCSI devices. This standard also defines the SCSI commands that may apply to any device model. 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.
