Abstract
An efficient reduction for the time delay during echo correction in a telecommunications network is made possible by a method for reducing an echo in uplink data (19 to 22) that are issued from a terminal (2, 3) of a telecommunications network (6, 8). A copy (25) of downlink data is created from downlink data (13) that are to be transmitted from the telecommunications network (6, 8) toward the terminal (3). Said copy (25) of downlink data is converted (transcoder 18) and used for the reduction (10) of echo in uplink data (21), whereas downlink data (13) are transmitted (6) toward the terminal (2, 3).
