Narrative:
C90 uses landlines to call ord tower. They are continually configured improperly. Several ucr's have been filed to no avail. In this situation, and during a previous missed approach, the landline problem was idented but not corrected in time. Aircraft Y was in 50 KT overtake (2 mi in-trail) to lead aircraft X, 4 mi from runway. Not answering radio, I had no way to coordination a missed approach with lead aircraft due to the landline problem. The approach controller finally reached the second aircraft and leveled it off for the missed approach. This problem will eventually lead to an operational error or an accident in my opinion.

Title: DUE TO LANDLINE CONFIGN PROBS BTWN TRACON AND TWR, TRACON CTLR ISSUED MISSED APCH TO LEAD OF 2 ACFT TO ENSURE SEPARATION AT RWY. RPTR STATES INCORRECT LANDLINE CONFIGN CONTINUOUS PROB BTWN THE 2 FACILITIES.
Narrative: C90 USES LANDLINES TO CALL ORD TWR. THEY ARE CONTINUALLY CONFIGURED IMPROPERLY. SEVERAL UCR'S HAVE BEEN FILED TO NO AVAIL. IN THIS SIT, AND DURING A PREVIOUS MISSED APCH, THE LANDLINE PROB WAS IDENTED BUT NOT CORRECTED IN TIME. ACFT Y WAS IN 50 KT OVERTAKE (2 MI IN-TRAIL) TO LEAD ACFT X, 4 MI FROM RWY. NOT ANSWERING RADIO, I HAD NO WAY TO COORD A MISSED APCH WITH LEAD ACFT DUE TO THE LANDLINE PROB. THE APCH CTLR FINALLY REACHED THE SECOND ACFT AND LEVELED IT OFF FOR THE MISSED APCH. THIS PROB WILL EVENTUALLY LEAD TO AN OPERROR OR AN ACCIDENT IN MY OPINION.
