Do Dacs have error correction?

If part of a digital signal is lost or corrupted by the cable between a CD player and a DAC does the DAC perform a redundancy check on the data and ask the CD player to resend it?

This is to settle yet another cable arguement, I think it does not as there is no outbound connection to the CD player from the DAC. I believe the CD player just sends a constant stream of data and if any data is lost or corrupted by a dodgy cable then it is lost.

Thanks in advance

If you are wondering how much signal correction is needed..
Connect your output via the cable to your computer. upload a disc to the harddrive with Exact Audio Copy or some such program.
The program TELLS you how much error is being fixed.
And believe me there is next to no error on a clean standard disc with ANY cable.
Some other programs out there probably can also tell you the information you want.
