Abstract
A method of proprietary TDMA (Time-Division Multiple Access) data modulated signals nonlinear signal splitting (switching) system is disclosed. Said TDMA system operates over distribution CATV infrastructure and in ES (extended spectrum) that is usually allocated above in the frequency band comparing to one defined in the CATV DOCSIS standard. Said system is meant to increase data throughput capacity over existing CATV based systems targeting primarily ES (Extended Spectrum band) by means of TDMA approach. The purpose of the RF switches based tap box is to connect specific device to which TDMA packet is relayed to. This approach reduces excessive losses that are present in standard tap boxes by disconnecting other devices, which are not receiving or sending related TDMA data packets. The described method introduces switch control receiver concept that allows for configuration of various operation modes such as regular switched TDMA, amplified and broadcast modes.
