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.
Claims8
An amplification system comprising:
- an input port;
- an output port;
- at least one amplifier;
- one or more amplifier ports operably coupled to the input and output ports;
- at least one diplexer operably coupled to the input and output ports;
- and
- a controller configured to:
- manage communications through the amplification system by turning on and off switches in upstream and downstream communication paths based, at least in part, on:
- a comparison between a first detected power and a first reference power;
- and
- a comparison between a second detected power and a second reference power,
- the at least one diplexer configured to at least isolate an extended spectrum (ES) band from one or more operating frequencies allocated to one or more DOCSIS signals.
