Interface for connecting data terminal to token-ring or bus local area network - connects data input=output unit of terminal unit to input of connection module contg. interface, which outputs to plug connector for data signal and impedance matching

摘要

A local area network (LAN) has connections to a data terminal (DEE) that has a data input/output (STK). This connects with a coupling module (Vn) via a line (LE1). The coupling module has an interface (SEn) and a plug connector (EC). The interface provides regeneration and level conversion of data signals. A further connection line (LE2) connects with a coupling unit (Vm) having a link (LE3) to a control unit (KOW) providing an active connectors to the network. ADVANTAGE - Provides matched connection to network with reduced noise.
