摘要： Embodiments of the present invention provide a crosstalk elimination method, an apparatus, and a system. The crosstalk elimination method in the present invention includes: when a quantity of online customer premises equipments CPEs is to change, determining a type of online CPEs before the change, and predetermining a type of online CPEs after the change, where the type of CPEs means that all online CPEs are nonlinear CPEs or are a mixture of nonlinear CPEs and linear CPEs, the linear CPEs are CPEs that support only linear crosstalk elimination for a line connected to the CPEs, and the nonlinear CPEs are CPEs that support both linear crosstalk elimination and nonlinear crosstalk elimination for a line connected to the CPEs; and if the determined type of online CPEs before the change is inconsistent with the predetermined type of online CPEs after the change, sending, according to a crosstalk elimination manner supported by the predetermined type of online CPEs after the change, switch instruction information to the online CPEs before the change. In the embodiments of the present invention, a problem that CPEs in different modes cannot access a network at the same time is resolved, and communication performance is improved.
