Circuit arrangement for operating several interfaces in LAN-network, has interfaces arranged in cascade with data network lines looped through

摘要

A circuit arrangement for driving several interfaces which are designed as access points and control the access between the wire-bound data network and a wireless data network (RF network). The interfaces (1) are arranged in cascade in which the lines (a...f) of the data network are looped through and the current supply of the further interfaces (1) from the first interface (1), results preferably with the help of reserve lines (e, f) available in the data cable. An Independent claim is given for an interface for a given circuit arrangement.
