DIGITAL SUBSCRIBER LINE ACCESS MULTIPLEXER USING CONTROL LINE AND DATA TRANSMISSION/RECEPTION METHOD USING THE SAME

摘要

PURPOSE: A digital subscriber line access multiplexer using a control line and a data transmission/reception method using the same are provided to perform an asynchronous message exchanging function using a plurality of control lines and an algorithm and implement a high speed control operation based on a simple control structure. CONSTITUTION: A main controller(100) receives an instruction from an operator and outputs a control signal and a data corresponding to the control signal. A sub unit(200) is formed in multiple units and receives a control signal from the main controller(100), checks an ID with respect to a data and obtains a valid data. The sub unit(200) receives a control signal from the main controller(100) through a control line(300). The sub unit(200) receives the data outputted from the main controller(100) based on a database(400). The data outputted from the main controller(100) is received into the sub unit(200) through the data bus(400).
