This standard is a conforming application of ISO 8879, SGML. This Standard describes the way in which the HTML language specified by the certain clauses (see standard) in the W3C Recommendation for HTML 4.01 shall be used, and does so by identifying all the differences between the HTML language specified by the W3C Recommendation for HTML 4.01 and the HTML language defined by this Standard.

Specifies a connection-oriented data transfer protocol supporting flow-controlled Read and Write sequences and non-flow-controlled, persistent-memory Put, Get and FetchOp sequences. For all sequences, small control messages are used to preallocate buffers at the data destination before the data movement begins, thus allowing the data to be moved immediately from the physical network into the end device's memory. The control and data messages may use different physical media or may share a single physical medium. Procedures are provided for moving data over HIPPI, Ethernet, and other media.

Specifies the physical and magnetic characteristics of a 0.5-in (12.65-mm)-wide 128-track magnetic tape cartridge, to enable physical interchange of such cartridges. It also specifies the quality of the recorded signals, a format - called Digital Linear Tape 3 Extended (DLT 3-XT) - and a recording method, thereby allowing data interchange between drives. The use of a labeling standard such as American National Standard for Information Technology - File Structure and Labelling of Magnetic Tapes for Information Interchange, ANSI X3.27-1987 (R1998), will support data interchange between data processing systems

This standard specifies the AT Attachment Interface between host systems and storage devices. It provides a common attachment interface for systems manufacturers, system integrators, software suppliers, and suppliers of intelligent storage devices.The application environment for the AT Attachment Interface is any host system that has storage devices contained within the processor enclosure.This standard defines the connectors and cables for physical interconnection between host and storage device, as well as the electrical and logical characteristics of the interconnecting signals. It also defines the operational registers within the storage device, and the commands and protocols for the operation of the storage device.This standard maintains a high degree of compatibility with the AT Attachment with Packet Interface Extensions standard (ATA/ATAPI-4), INCITS 317, and while providing additional functions, is not intended to require changes to presently installed devices or existing software.

This International Standard defines the signalling procedures and protocol for the purpose of circuit-switched Call Control at the Q-reference point between Private Integrated Network Exchanges (PINXs) connected together within a Private Integrated Services Network (PISN). The Q reference point is defined in ISO/IEC 11579-1. This International Standard is based upon that described in ITU-T Recommendation Q.931, including the provisions for symmetrical operation described in annex D of that recommendation.

This standard establishes the format of information on 25.4 mm (1 in) type DCRsi instrumentation digital cartridges. It specifies the dimensions and locations of the transverse scan data and pilot tone track, the control track and the longitudinal data track. It defines the formatting, randomizing, ECC, and other recording requirements of the data blocks forming the transverse data record, containing user data and other associated data and specifies the content, format, and recording method for the control record to ensure that a compliant recorder will be able to reproduce the recorded tape. This standard also specifies the recording requirements for the longitudinal records contained in the longitudinal data tracks. Additionally this standard specifies the prerecord and post-record zones of the transverse scan tracks and the longitudinal data track. The physical requirements, magnetic requirements and test methods for the magnetic tape and tape cartridge are also specified in this standard. All dimensions given are metric with their corresponding U.S. customary engineering units (similar to British Imperial units) shown in parentheses.
