Narrative:
Aircraft X was released from tvc tower to depart runway 10; turn right to 180 degrees. (Climbing to 3000 ft issued by tower per SOP.) after departure the aircraft was radar idented and issued a climb to 5000 ft. Traffic was issued for aircraft Y overhead at 6000 ft. I then turned aircraft X to a 140 degree heading. Shortly after I became aware aircraft X was climbing past 5000 ft. I advised that 5000 ft was assigned altitude. When aircraft X was still climbing I had aircraft make immediate descent. Tower shout line OTS. All coordination with tower on dial line. This line has had problems for 2-3 weeks. Adds additional workload to sector; although not a direct cause.

Title: ZMP CTLR DESCRIBED LOSS OF SEPARATION WHEN BE20 CLBED ABOVE ASSIGNED ALT TO OCCUPIED ALT.
Narrative: ACFT X WAS RELEASED FROM TVC TWR TO DEPART RWY 10; TURN R TO 180 DEGS. (CLBING TO 3000 FT ISSUED BY TWR PER SOP.) AFTER DEP THE ACFT WAS RADAR IDENTED AND ISSUED A CLB TO 5000 FT. TFC WAS ISSUED FOR ACFT Y OVERHEAD AT 6000 FT. I THEN TURNED ACFT X TO A 140 DEG HDG. SHORTLY AFTER I BECAME AWARE ACFT X WAS CLBING PAST 5000 FT. I ADVISED THAT 5000 FT WAS ASSIGNED ALT. WHEN ACFT X WAS STILL CLBING I HAD ACFT MAKE IMMEDIATE DSCNT. TWR SHOUT LINE OTS. ALL COORD WITH TWR ON DIAL LINE. THIS LINE HAS HAD PROBS FOR 2-3 WKS. ADDS ADDITIONAL WORKLOAD TO SECTOR; ALTHOUGH NOT A DIRECT CAUSE.
