ABSTRACT:
A digital signal line transmission system with reduced echo is provided. A communication line is between a carrier and a user terminal. A bridgetap line has a first end connected to the communication line. An adaptor having a capacitance is connected to the bridgetap line. The adaptor reduces the effect of echo from the bridgetap line on a rate of data transmission to the user terminal over the communication line.
