Abstract
In a network a star node (SN1) interconnects a plurality of stations (ST1–ST3). The star node (SN1) has interfaces (I1–I3), each having a connection terminal (BP) for connecting a selected one of the stations to the star node (SN1) and each interface receives at a connection terminal (BP) a signal from the station associated with that interface and forwards the received signal to the connection terminal (BP) of the other interfaces. The star node (SN1) further has a common terminal (RT1) and each interface has a receiver (CMP1) coupled to the connection terminal (BP) for receiving the signal from the associated station, a transmitter (TR) coupled to the connection terminal (BP), a first activity detector (A1) for generating a first activity signal (AS1) in response to signal transitions at an input (CIP1) of the receiver (CMP1), a second activity detector (A2) for generating a second activity signal (AS2) in response to signal transitions at the common terminal (RT1), a first switch (SW1) for disabling signal transfer from the receiver (CMP1) to the common terminal (RT1) in response to the second activity signal (AS2), and a second switch (SW2) for disabling signal transfer from th…
