<p>The present invention discloses a method and a device for dynamically adjusting pre-emphasis and equalization parameters of chips. The device comprises a mapping relationship establishment module, an adjustment information acquirement module and a parameter calculation module. The method for dynamical adjustment comprises the following steps: an element mapping relationship table is established by the mapping relationship establishment module; when plug board information of the optical transmission equipment is adjusted, the adjustment information acquirement module acquires adjustment information and reports the adjustment information to the parameter calculation module; the parameter calculation module firstly recalculates the total length of transmission lines among connected single boards according to the adjusted plug board information and the element mapping relationship table, then recalculates pre-emphasis and equalization parameter values according to the total length of transmission lines and the chip types of the connected single boards, and informs the parameter values to a main control board, after that, the main control board transmits the parameter values to each single board. By adopting the present invention, the main control board can dynamically adjust the pre-emphasis and equalization parameters and inform the parameters to each single board in time, thus ensuring that each single board can adjust message signals according to the adjusted pre-emphasis and equalization parameters, and improving the transmission quality of the message signals.</p> |
