PhoneNET is a discontinued implementation of the AppleTalk networking physical layer created by the Berkeley Macintosh Users Group (BMUG) and commercialized by Farallon Computing (now Netopia). It used conventional four-conductor telephone Category 1 patch cords and RJ-11 modular connectors in place of Apple's more complex cabling system. It was far more popular than Apple's implementation before the widespread implementation of Ethernet.
