It means that the upstream switch is getting bad frames from you.

Coordinate your E1 linecoding/framing /CRC with the other end and intermediate equipment (if any). Or just play around with these parameters on your controller, there are not many choices.

If it does not help, call engineer on the other end and ask what exact errors they are getting and post them along with error counters on your controller.
