Zusammenfassung:	Bidirectionally communicating terminals are connected to a serial loop by interfaces which provide no delay. Communications are effected in fixed length time slots which include an indicia of the state of the slot. Slots carrying data to a terminal have the state indicia set to value which indicates that the slot is in use. At the receiving terminal, the indicia is retained in the state if the terminal is to use the slot for transmitting data. If the receiving terminal has no data to send, the state indicia is reset to a different value. In the reset state, the slot is available to subsequent terminals for the transmission of data.
