Expandable repeater

A repeater, comprising:

• N repeater circuits, each of the N repeater circuits having an Input/Output port for transmitting a clock, data, control and collision signal, a request-for-access signal within the control signals being asserted as repeater circuit is requesting a data repetition:
• an integrator means having N Input/Output interfaces each of which being coupled to the corresponding Input/Output port of said N repeater circuits, for selectively executing the data repetition and generating the collision signal, in response to the clock and control signals, so that said repeater functions as a single repeater, the integrator means comprising a data/collision handler, in response to the request-for-access signal of each Input/Output port, for generating a repetition request signal and the collision signal, wherein the data/collision handler comprises:
• a resistor circuit having N resistors each of which have a resistance of R, a first end of each resistor being adapted to receive one corresponding request-for-access signal, a second end of each resistor being coupled to a common terminal for generating a first voltage signal;
• a first means for generating the repetition request signal by comparing the first voltage signal with a first reference signal;
• and
• a second means for generating the collision signal by comparing the first voltage signal with a second reference signal.
