An expandable repeater includes N repeater units connected to an integrator device and a bus. Each of the N repeater units has an input/output connected to the bus for exchanging clock, data, and to receive network status signals. Each repeater unit also provides status signals to the integrator device. The status signals indicate the data repetition status of that repeater unit to the integrator. The integrator receives N (where N is the number of repeater units to be combined by the integrator) sets of status signals from the repeater units, supplies network status information to the bus, and exchanges clock information and data with the bus. The integrator selectively executes the data and clock repetition, and provides a global network status signal in response to the status signals received from all of the repeater units connected to the integrator. A number of integrators may be combined in a similar fashion to further expand the repeater. The combinations may be continued, resulting in an hierarchical arrangement of integrators which provides an infinitely expandable repeater.
