A method and transmitter receiver sets are used to perform communication in digital subscriber line technology. The method includes: acquiring communication performance parameter; the first transmitter receiver set and the second transmitter receiver set using the predetermined communication standard to perform communication when the communication performance parameter is equal to the predetermined value or greater than the predetermined value, the predetermined communication standard is respectively set in the first transmitter receiver set and the second transmitter receiver set. The bit table and the gain table predetermined are respectively stored in the first transmitter receiver set and the second transmitter receiver set. According to the method, a rapid switch to the bit table and the gain table predetermined using simple message or enquiry answer mechanism may be ensured when great wideband noise exists. There is no need of interchanging the bit table and the gain table when using this method.
