Why would I be getting an notice to appear in court for support?

Back in November I won my case against my ex for nonpayment of child support and he began to serve 6 months weekends in jail starting Christmas Eve. He has continued these weekends as I understand although there has again been no payments since the tail end of January. Today I received a petition to appear in court on the matter of support, as my ex as the petitioner. A copy of this doent was sent to child support, my ex, myself, and my lawyer from the hearing. Stated in the petition is the purpose of "restored." Can someone tell me what this means and what I might be able to expect on this date aside from an adjournment?
