Each terminal equipment establishes its optical output level to be the largest one of the levels informed thereto. Further, each terminal equipment measures the delay time of an acknowledge bit transmitted from the other terminal equipments to thereby shift the sampling point by the mean value of the measured delay time, so that bus connection of terminal equipments through optical fiber can be facilitated, channel access control based on CSMA/CD can be performed, and wiring between the terminal equipments can be conserved by performing multiple transmission of audio signals and video signals as well as digital data.

Abstract: A communication control method for use in a communication system including a plurality of communication control apparatuses interconnected through an information transmission path, each of the communication control apparatuses including a packet transmission/reception unit, a timer unit and a controller unit. When a first communication control apparatus has become unable to perform communication due to accidental power-off or a power supply failure or the like in the course of communication with a second communication control apparatus (which has been brought into a locked state by the first communication control apparatus), the invention prevents the second communication control apparatus from being left permanently in the locked state.

Abstract: In cases where a first communication control unit locks a second communication control unit to communicate with the second unit, the first unit stores a data representing a time remaining until the locking of the second unit is released. In these cases, the second unit stores a data representing an address of the first unit as a lock address corresponding to an address of a unit which locks the second unit. In cases where a third communication control unit tries to communicate with the second unit and fails the communication with the second unit, the third unit connects with the second unit and reads out the data representative of the lock address from the second unit, and then the third unit connects with the first unit in response to the lock address and reads out the data representative of the lock remaining time from the first unit. The third unit retries to communicate with the second unit after the lock remaining time elapses.
