GENERAL DESCRIPTION

The MTD392 family includes a series of products, MTD392/3/4 and MTD492/3/4. The MTD392 product family

is built for easy MAU interface in a coaxial Ethernet network. The MTD392 product family integrates the coaxial

cable interface functions of Medium Attachment Unit (MAU) in Ethernet or Cheapernet LAN applications. In an

Ethernet 10Base5 network, the MTD392 product family is mounted on the thick Ethernet coaxial cable and

connects to a station through an AUI cable. For Cheapernet applications, the MTD392 product family is

connected to the Cheapernet coaxial cable through a BNC connector and is usually mounted on the LAN

adapter in a station.
