Abstract:
In a communication system including a plurality of communication apparatuses connected via a data transmission line to execute data exchange between any of the communication apparatuses,said plurality of communication apparatuses including a transmitter and receiver configured to access said data transmission line at timing periods peculiar to respective communication apparatuses in synchronism with a common system clock among respective communication apparatuses, said plurality of communication apparatuses being connected to external devices having different communication speeds for communicating with a corresponding communication apparatus, said timing periods peculiar to respective communication apparatuses communicating with other communication apparatuses in the communication system are set to be mutually shifted such that accesses to said data transmission line are not simultaneously generated from said plurality of communication apparatuses, and at least two communication apparatuses of the plurality of communication apparatuses have communication speeds for communicating with other communication apparatuses in the communication system that are different from each other.
