The present invention relates to the field of communications technologies, and in particular, to a power adjustment device and method, so as to resolve a problem of an abnormality caused by the fact that a receive end cannot perform receive power adjustment according to far end crosstalk FEXT. A vectoring control entity VCE provided by embodiments of the present invention includes: a downlink FEXT determining module, configured to determine a power value of downlink FEXT caused to a signal on a line corresponding to a port i by a signal on a line corresponding to a port j, and a receive power value of an FTU-R corresponding to the port i; and a downlink receive power adjustment module, configured to: when the port i is activated, determine, according to the two power values determined by the downlink FEXT determining module, a virtual power margin corresponding to the port i and send the virtual power margin to the FTU-R corresponding to the port i, so that the FTU-R performs receive power adjustment according to the virtual power margin. The device provided by the embodiments of the present invention can adjust a receive power according to FEXT, thereby avoiding an abnormality of a transceiver unit caused by an excessively large receive power. |
