Patent Images
1. A data communications system, which comprises:
- a first node for transmitting an output digital signal to a second node through a transmission line and receiving an input digital signal from the second node through a reception line, wherein the first node having a transmission port for transmitting the output digital signal and a reception port for receiving the input digital signal; and
a signal processing amplification block for compensating an attenuation of the input digital signal and preventing a crosstalk between the transmission line and the reception line, wherein an input port of the signal processing amplification block is connected to the second node through the reception line and an output port of the signal processing amplification block is connected to the reception port.

Abstract
In a data communications system, a first node transmits an output digital signal to a second node through a transmission line and receives an input digital signal from the second node through a reception line, a signal processing amplification block of the data communications system compensates an attenuation in the input digital signal and prevents a crosstalk between the transmission line and the reception line, and a regulating block for preventing a crosstalk receives a branch signal and generates a control signal based on a capacity of the branch signal.

13. A data communications system, which comprises:
-
a first node for transmitting an output digital signal to a second node through a transmission line and receiving an input digital signal from the second node through a reception line, wherein the first node having a transmission port for transmitting the output digital signal and a reception port for receiving the input digital signal;
an amplification device for amplifying the input digital signal, wherein an input port of the amplification device is connected to the second node through the reception line and an output port of the amplification device is connected to the reception port; and
a regulating block, coupled to the amplification device, for generating a control signal to alter an amplification gain of the amplification device, to thereby prevent a crosstalk between the transmission line and the reception line.
