The errors you are getting are not errors you can fix by yourself, you will need to work with the vendor. You can make sure that it is not a physical problem with the DS1 board by putting a loopback plug into it and see if it clears up and runs clean.

If it runs clean looped back to itself then you know that it is not a board failure. Next plug your cable back in and loop it back from the demarc, if it still runs clean then you know it is not your wiring or board. Restore the circuit and call the vendor.

To make a loopback jack and plug (because you will need both), loop the white/blue pair to the white/orange pair. Physically that is leads 1 & 2 to leads 4 & 5.
