Title: Method and circuit arrangement for transmitting data signals between data signal receiving devices/data signal transmitting devices which are connected to one another via a highway system
Inventor: BITZINGER RUDOLF DIPL ING
IPC: H04L12/433
Filed: 1981-09-15
Abstract: The invention relates to a method and a circuit arrangement for transmitting digital signals between data signal receiving devices/data signal transmitting devices (CD1 to CDn) which are connected to one another via a highway system (CB, LB). In this case, it is assumed that, in the case when a data signal transmitting device is just in the data signal transmitting stage, all the other data signal transmitting devices are inhibited in terms of transmitting data signals. In order to ensure particularly reliable operation, the invention provides that only the relevant one data signal transmitting device (for example CD1) is controlled into the data signal transmitting state, in that a separate enable signal is provided only to it, which enable signal is passed on from this data signal transmitting device (CD1) to the next data signal transmitting device (CD2) in the highway system (CB, LB) at the earliest after completion of the data signal transmission from the one said data signal transmitting device (CD1). <IMAGE>
