摘要： A local area network (LAN) having a 10Base-T media attachment unit (MAU) is disclosed for coupling an attachment unit interface (AUI) to a twisted pair link through an AUI port of the 10Base-T MAU. In addition to meeting or exceeding standards set forth in the proposed supplement (P802.3I/D10) to IEEE standard 802.3 for LANs, the MAU provides an interface between the AUI and a RJ45 (twisted pair) connector which auto-engages when activity is detected on the twisted pair link. Lack of activity on the twisted pair link forces the 10Base-T MAU to isolate its AUI port from the AUI. An Ethernet (coaxial) type MAU commonly connected with the 10Base-T MAU at the AUI may be utilized without manual intervention when the twisted pair link is inactive.
