| 摘要 |
The present invention concerns a method related to clock delay compensation, especially related to connection of data communication equipment (DCE) to modems and other types of data transmission equipment (DTE), the data signals having an arbitrarily delay through the cable in question, and the DCE comprising a detecting clock, and for the purpose of avoiding sampling of data close to the transitions, this problem is overcome by using the transition on the transmitted data (T-curcuit on X.21) as a reference for adjusting (resetting) a counter which controls the data sampling, for thereby ensuring that data is always clocked in the middle of the symbol (data cell).
