[Common Usage] IECSA Volume I A-4 Final Release (Not Intended for Redistribution - Pending Copyright Release) A ABR (Area Border Router): Routers that belong to multiple areas, called area border routers (ABR), have the duty of disseminating routing information or routing changes between areas. [Common Usage] Abstract Communication Service Interface (ACSI): Virtual interface to an IED providing abstract information modeling methods for Logical-Devices, Logical-Nodes, Data, and Data Attributes, and communication services e.g. connection, variable access, unsolicited data transfer, device control and file transfer services, independent of the actual communication stack and profiles used. [IEC 61850-2] Abstract Syntax: In open systems architecture, the specification of application-layer data or application-protocol control information by using notation rules that are independent of the encoding technique used to represent the information. [T1 Glossary 2000: Glossary of Telecommunications Terms] Abstract Syntax Notation One (ASN.1): A standard, flexible method that (a) describes data structures for representing, encoding, transmitting, and decoding data, (b) provides a set of formal rules for describing the structure of objects independent of machine-specific encoding techniques, (c) is a formal network-management Transmission Control Protocol / Internet Protocol (TCP/IP) language that uses human-readable notation and a compact, encoded representation of the same information used in communications protocols, and (d) is a precise, formal notation that removes ambiguities.
