ABSTRACT:
Data signals from a telecommunication network are routed to a gateway which generates analog signal distributed to receivers within a customer premises. A network interface device receives digital signals from the telecommunication network. A first diplexer has a digital signal port connected to the network interface device. The first diplexer combined signal port is connected with the combined signal port of a second diplexer. The gateway receives digital signals from the second diplexer digital signal port and provides analog signals to the second diplexer analog signal port. Analog signals are then available to receivers at both the first diplexer analog signal port and the second diplexer analog signal port.
