The AES3 standard parallels part 4 of the international standard IEC 60958. Of the physical interconnection types defined by IEC 60958, three are in common use:
IEC 60958 Type I Balanced - 3-conductor, 110-ohmtwisted pair cabling with an XLR connector, used in professional installations (AES3 standard)
IEC 60958 Type II Unbalanced - 2-conductor, 75-ohm coaxial cable with an RCA connector, used in consumer audio
IEC 60958 Type II Optical - optical fiber, usually plastic but occasionally glass, with an F05 connector, also used in consumer audio
F05 connectors, 5mm connectors for plastic optical fiber, are more commonly known by their Toshiba brand name, TOSLINK. The precursor of the IEC 60958 Type II specification was the Sony/Philips Digital Interface, or S/PDIF. For details on the format of AES/EBU data, see the article on S/PDIF.

A method for inserting standardized unique identifiers into the AES3 stream is specified in AES52-2006, specifically covering the UMID (Unique Material Identifier specified in SMPTE 330M-2000) and the UUID (Universally Unique Identifier as documented in ISO/IEC 11578:1996 and IETF RFC 4122).
An extension of the AES3 interface has been developed by the Society of Motion Picture and Television Engineers (AES3_SMPTE), and it specifies a method for using the interface to transmit non-PCM AC3 compressed audio and other data.
Annex D, however, discusses the carriage of AES3 signals on structured wiring, e.g., the "category 5" cables associated with computer network installations, a topic that receives extended treatment in AES47, which specifies the method of carrying multiple channels of audio in linear PCM or AES3 format across an asynchronous transfer mode (ATM) network.
The digital audio standard frequently called AES/EBU that is officially known as AES3, was first published in 1992 as a standard (and revised in 1995, 1998, and 2003) for carrying digital audio signals between various devices.
The AES3 standard parallels part 4 of the international standard IEC 60958.
The standard for packing AES3 frames into ATM cells is AES47, and is also published as IEC 62365.
