The analysis of the operating conditions of the echo cancellation mechanisms in the Carrier-in-Carrier (C-I-C) technology was performed. The main factors that have a negative impact on the process of adaptive tuning of the echo canceller are considered. The results of the analysis of
the basic echo cancellation algorithms properties in the C-I-C system are presented. The solutions to ensure the necessary stability and degree of interfering signals suppression are presented.
