Appendix F: Acronyms It is typical of the engineering books to be full of acronyms that constitute a sort of barrier for the comprehension of the text by a technician of a different field. This book is no exception, but we have tried to limit the problem related to acronyms by inserting the following table. Here the acronyms are explained, not always with their literary meaning, but sometimes also with different words more suitable to describe their significance. Moreover, for each acronym, the field where it is more used is indicated as a reference. Acronym What Does It Stand For Where It Is Used Authentication, Authorization, and Network Management and Control Accounting American Telecommunication Act Telecommunication Market Add Drop Card Transmission Systems Analog Digital Converter Electronic Circuits and Equalizers Add-Drop Multiplexer Network Switching Entities Asymmetric Digital Subscriber Line Broadband Access Automatic Gain Control Optoelectronic Components and Sub-Systems Arithmetic Logical Unit Carrier Class Ethernet American Standardization Institute Standardization Bodies Avalanche Photodiode Optoelectronic Components and Sub-Systems ATM Passive Optical Network Broadband Access Automatic Protection Switching Protocol SDH/SONET Anti Reflection Optoelectronic Components and Sub-Systems Average Revenue per User Telecommunication Market Amplified Spontaneous Emission Optical Amplifiers Application Specific Integrated Circuit Electronics Circuits and Equalizers ASN (I) Abstract Syntax Notation Network Management and Control ASN (II) Automatic Switched Network Generalized Multiprotocol Label Switching (GMPLS) Automatically Switched Optical Network Networks Management and Control Asynchronous Transfer Mode Networks Management and Control Array Waveguide Optoelectronic Components and Sub-Systems Bridge Data Unit Carrier Class Ethernet Bose Chaudhuri Hocquenghem Code Electronic Circuits a
