I hope to find the solution
Please

The precision of manufacturing of connectors and cables decreases along with the price, and one contact not matching well between the plug and the receptacle is sufficient to cause bit errors which get detected by means of FCS and thus reported as FCS errors.

So take the usual procedure to isolate the root cause:

1. use another cable
2. use another port on the CCR1016
3. connect something else that can indicate FCS errors instead of the CCR1016

to identify whether the issue is within your reach (bad cable, bad port on CCR, all ports on CCR bad) or out of it (anything else - if you get the FCS errors also on the other box, the data get corrupt between your upstream ISP’s gear and your last patchcord).
