Abstract - (Show below) - (Hide below)

Defines a means to carry multiple channels of digital audio in AES3 or bit-stream formats, plus system synchronisation information, over a structured data cable using the IEEE Std 802.3 physical layer. Also includes a means to convey arbitrary packet-based data over the link, in addition to the specified audio interconnection.
