[SI-LIST] Re: ECHO cancellation hybrid

Hi venu,

EC is a technique to perform full duplex data transmission on a single pair
of wires, e.g., twisted pair. What EC does is to remove the transmit signal
from the received signal.  Of course, there will be  EC done in the LIU or
framer device as well.

Regards,

Fred
