Abstract

In a method and an apparatus for echo compensator connection for telephone connections in a telecommunication network that has a plurality of network groups (10), each network group has at least one remote node and a plurality of subscriber stations (14) that are connected to the remote node (12) via network group lines (18). The size of the network groups is selected such that echo compensation is not required given the maximum signal running times occurring within a respective network group (10). The remote nodes (12) of various network groups (10) are connected to one another by long-distance trunks (20). An echo compensator (22) is looped into the connection in the respective remote node (12) of the originating network group and of the destination network group given setup of a telephone connection between two network groups.
