This Local and Metropolitan Area Network standard, ISO/IEC 8802-5:1998, is part of a family of local area network (LAN) standards dealing with the physical and data link layers as defined by the ISO/IEC Open Systems Interconnection Basic Reference Model. Its purpose is to provide compatible interconnection of data procesing equipment by means of a LAN using the token-passing ring access method ...

This amendment specifies the changes required to IEEE 802.5, 1999 Edition (ISO/IEC8802-5:1998 base standard), IEEE Stds 802.5r and 802.5j, 1998 edition (ISO/IEC 8802-5:1998/Amd. 1:1998), and IEEE Std 802.5t-1999, to support 1000 Mbits/s Dedicated Token Ring (DTR) operation. The base standard together with Amendment 1 specifies shared and dedicated (point-to-point) Token Ring operation at both 4 and 16 Mbits/s using either the TKP Access protocol or the TXI Access Protocol. This standard extends Token Ring operation to 1000 Mbits/s for the DTR C-Port and Station using the TXI Access Protocol. Extensions to the Media Access Control have been made to accommodate the requirements for the 1000 Mbits/s media rate.

This supplement to IEEE 802.9-1994 defines the architecture, frame structure, service specifications, physical layer, management, signaling and the relationship with ISO/IEC 8802-3 1993 networks, for the 16.384 Mbit/s PHY.

Abstract: This recommended practice encompasses the monitoring of electrical characteristics of single-phase and polyphase ac power systems. It includes consistent descriptions of conducted electromagnetic phenomena occurring on power systems. This recommended practice describes nominal conditions and deviations from these nominal conditions that may originate within the source of supply or load equipment or may originate from interactions between the source and the load. Also, this recommended practice discusses power quality monitoring devices, application techniques, and the interpretation of monitoring results. Keywords: assessment, compatibility, dip, distortion, electromagnetic phenomena, harmonics, imbalance, instruments, monitoring, power quality, rms variation, sag, swell, transient, unbalance.

A highly useful international standard that provides for the compatible interconnection of data processing equipment via a local area network using the token-passing ring access method.
