ABSTRACT:
A system and method for splitting and combining signal in a Cable Modem Terminal Station (CMTS). This system uses a hierarchal approach to connect RF modules to PHY modules. A first splitter and combiner connects each N input in a module to each of N outputs. Each of Nth output is then connected to a Nth second splitter/combiner which in turn connects each input to each output.
