PhoneNET

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.

Later the same year, Reese M. Jones of the Berkeley Macintosh Users Group created an alternative dongle that connected together using conventional telephone cabling with RJ-11 connectors.

Connecting together a network using these "BMUGnet" was much less expensive than using Apple's system and could often be accomplished using existing telephone wiring already installed in buildings.

Unlike LocalTalk's four-wire grounded implementation, PhoneNET used a single twisted pair, or the outside two wires of a four-conductor flat cable.
