GENERAL DESCRIPTION
The MTD492 transceiver integrates the coaxial cable interface functions of the Medium Attachment Unit
(MAU) in Ethernet or Cheapernet LAN applications. In an Ethernet 10Base5 network, MTD492 is mounted
on the thick Ethernet coaxial cable and connects to a station through an AUI cable. For Cheapernet
applications, MTD492 is connected to the Cheapernet coaxial cable through a BNC connector and is
usually mounted on the LAN adapter in a station.
