From Wikipedia, the free encyclopedia.
Multiport repeater: In digital networking, an active device, having multiple input/output (I/O) ports, in which a signal introduced at the input of any port appears at the output of every port.
Note 1: A multiport repeater usually performs regenerative functions, i.e. , it reshapes the digital signals.
Note 2: Depending on the application, a multiport repeater may be designed not to repeat a signal back to the port from which it originated.
