Narrative:

Small aircraft X departed at satellite airport north of ind. According to the letter of agreement, he should have climbed to 10000 ft out the departure gate. The ind ATC tower departure controller, however, the ind ATC tower departure controller appreqed through the manual (d-side) controller, climbing to 10000 ft and alluded to the arrival gate, although not specifically coordinating the aircraft's route through the arrival gate. Air carrier Y was on arrival over mie on the clang arrival to ind. He was issued a crossing of 30 DME northeast of bhp at 10000 ft, according to the letter of agreement. C/a activated between the 2 aircraft,, but I assumed that approach control was separating the aircraft with the arrival. My manual controller had not informed me of any coordination that had taken place. Small aircraft X called on my frequency out of 9000 for 1000 ft. His initial call wa at the same time another aircraft called, so I did not hear it or acknowledge it. C/a was activated between 2 other pairs of aircraft and my attention was drawn to them. I missed small aircraft X's second call on leaving 9700 for 10000 ft. Approach called the d-side and informed him about the 2 aircraft running together and he informed me aedp had already activated and I turned the air carrier Y not knowing that small aircraft X was on frequency. He called on a third time level 1000 ft and I climbed him to 11000 ft. I feel that this error was caused by a non radar qualified manual controller answering radar lines, and doing radar coordination west/O training and west/O the other controller (approach) knowing he was coordinated with a d-side. Supplemental information from acn 120020: ZID said nothing about direct rod or on a specific heading, so I assumed small aircraft X was going out the departure gate.

Title: SMA CONFLICTED WITH AN OPPOSITE DIRECTION ACR AT THE SAME ALT.

Narrative: SMA X DEPARTED AT SATELLITE ARPT N OF IND. ACCORDING TO THE LETTER OF AGREEMENT, HE SHOULD HAVE CLBED TO 10000 FT OUT THE DEP GATE. THE IND ATC TWR DEP CTLR, HOWEVER, THE IND ATC TWR DEP CTLR APPREQED THROUGH THE MANUAL (D-SIDE) CTLR, CLBING TO 10000 FT AND ALLUDED TO THE ARR GATE, ALTHOUGH NOT SPECIFICALLY COORDINATING THE ACFT'S ROUTE THROUGH THE ARR GATE. ACR Y WAS ON ARR OVER MIE ON THE CLANG ARR TO IND. HE WAS ISSUED A XING OF 30 DME NE OF BHP AT 10000 FT, ACCORDING TO THE LETTER OF AGREEMENT. C/A ACTIVATED BTWN THE 2 ACFT,, BUT I ASSUMED THAT APCH CTL WAS SEPARATING THE ACFT WITH THE ARR. MY MANUAL CTLR HAD NOT INFORMED ME OF ANY COORD THAT HAD TAKEN PLACE. SMA X CALLED ON MY FREQ OUT OF 9000 FOR 1000 FT. HIS INITIAL CALL WA AT THE SAME TIME ANOTHER ACFT CALLED, SO I DID NOT HEAR IT OR ACKNOWLEDGE IT. C/A WAS ACTIVATED BTWN 2 OTHER PAIRS OF ACFT AND MY ATTN WAS DRAWN TO THEM. I MISSED SMA X'S SECOND CALL ON LEAVING 9700 FOR 10000 FT. APCH CALLED THE D-SIDE AND INFORMED HIM ABOUT THE 2 ACFT RUNNING TOGETHER AND HE INFORMED ME AEDP HAD ALREADY ACTIVATED AND I TURNED THE ACR Y NOT KNOWING THAT SMA X WAS ON FREQ. HE CALLED ON A THIRD TIME LEVEL 1000 FT AND I CLBED HIM TO 11000 FT. I FEEL THAT THIS ERROR WAS CAUSED BY A NON RADAR QUALIFIED MANUAL CTLR ANSWERING RADAR LINES, AND DOING RADAR COORD W/O TRNING AND W/O THE OTHER CTLR (APCH) KNOWING HE WAS COORDINATED WITH A D-SIDE. SUPPLEMENTAL INFO FROM ACN 120020: ZID SAID NOTHING ABOUT DIRECT ROD OR ON A SPECIFIC HDG, SO I ASSUMED SMA X WAS GOING OUT THE DEP GATE.
