1. A data interface equalization adjustment method for a communication system, the data interface equalization adjustment method comprising:
determining, by a second device, equalization parameter indication information of a first transmitter (TX) on a first data interface, the communication system comprising a first device and the second device, the first device comprising the first data interface, the second device comprising a second data interface, the first data interface and the second data interface being connected over a link;
sending, by the second device, a first equalization training sequence block (ETSB) to a corresponding receiver (RX) on the first data interface through a TX on the second data interface, the first ETSB carrying the equalization parameter indication information and equalization target indication information, the equalization target indication information indicates that the first TX is an equalization target; and
determining, by the first device, the equalization target to be the first TX based on the equalization target indication information; and
adjusting an equalization parameter of the first TX to an equalization parameter indicated by the equalization parameter indication information.
