Abstract
A method of bidirectional amplification of proprietary TDMA (Time-Division Multiple Access) data modulated signals over CATV infrastructure is described. A method of upstream/downstream switching based on carrier detection/measurement originated from the master and slave modems embodiment is described, along with upstream/downstream direction switching based on the encoded switching command detection, originating from the master modem.
