ABSTRACT:
A digital signal line echo reduction adaptor is configured to connect adjacent to a first end of a bridgetap line. The bridgetap line has a second end connected to a carrier communication line. The digital signal line echo reduction adaptor reduces an effect of echo from the bridgetap line on a rate of data transmission over the carrier communication line.
