Narrative:
The sector was rather busy and traffic was increasing. There was a lot of coordination on the landlines and override calls coming in. Extra attention was needed due to new rvsm implementation and new altitudes at surrounding sectors. The radar climbed air carrier Y to FL280 and typed in an interim altitude of FL260. Air carrier X climbed into crossing traffic at FL270. He quickly issued turns in an attempt to receive lateral separation.

Title: ZID RADAR ASSOCIATE CTLR OBSERVED OPERROR AT FL270 AS CTLR FAILS TO RESTRICT CLBING ACFT BELOW XING TFC.
Narrative: THE SECTOR WAS RATHER BUSY AND TFC WAS INCREASING. THERE WAS A LOT OF COORD ON THE LANDLINES AND OVERRIDE CALLS COMING IN. EXTRA ATTN WAS NEEDED DUE TO NEW RVSM IMPLEMENTATION AND NEW ALTS AT SURROUNDING SECTORS. THE RADAR CLBED ACR Y TO FL280 AND TYPED IN AN INTERIM ALT OF FL260. ACR X CLBED INTO XING TFC AT FL270. HE QUICKLY ISSUED TURNS IN AN ATTEMPT TO RECEIVE LATERAL SEPARATION.
