ACR X CLB THROUGH OCCUPIED ALT HAD LTSS FROM ACR Y. SYS ERROR. ACR X AND Y RECEIVED TCASII RA.

Narrative

ACR X WAS NEBOUND DIRECT TO SJN AND HAD LEVELED AT FL330. ACR Y WAS SWBOUND ON J18 AND LEVEL AT FL350. ACR X REQUESTED CLB TO FL370. THE ACFT WERE HEAD ON ABOUT 20-25 MI APART. I WENT OFFLINE TO COORDINATE SOMETHING. WHEN I GOT OFF THE LINE I NOTICED ACR X HAD AN ASSIGNED ALT OF FL370 AND HIS MODE C READOUT SAID FL333. I THEN POINTED TO THE DATA BLOCK AND ASKED MY RADAR MAN IF THE ACFT WAS CLBING. HE GAVE NO RESPONSE BUT IMMEDIATELY BEGAN ATTEMPTING TO SEPARATE THE ACFT. HE FIRST TRIED TO TURN ACR X TO A HDG OF 100 AND DSND AND MAINTAIN FL330 BUT THERE WAS NO RESPONSE FROM THE ACFT. HE THEN ATTEMPTED TO TURN ACR Y TO A HDG OF 270 FOR TFC. STILL NO RESPONSE. ONCE AGAIN; HE TURNED ACR X TO HDG 100 DSND AND MAINTAIN FL330. THE ACFT ACKNOWLEDGED. HE THEN SAID TO EXPEDITE THE TURN BUT SAID WRONG A/N. HE THEN TURNED ACR Y TO HDG 360 FOR TFC. THE ACFT RESPONDED AND SAID HE WAS CLBING FOR A TCASII ALERT. HE THEN TOLD ACR Y TO CLB AND MAINTAIN FL390. ACR X RPTED THE ACR Y IN SIGHT AND EXPEDITING TURN. BOTH ACFT LATER REQUESTED EACH OTHER'S CALL SIGN SINCE BOTH HAD RECEIVED A TCASII ALERT. I BELIEVE A TFC SEARCH WAS NOT ACCOMPLISHED PRIOR TO CLBING ACR X. ALSO WE HAD HAD NUMEROUS PROBLEMS WITH OUR XMITTERS SINCE CLRNCS WERE GIVEN 2 AND 3 TIMES TO SEVERAL ACFT DURING THAT PERIOD. THE XMITTERS HAD BEEN RPTED AS BEING PATCHY IN SOME AREAS EARLIER IN THE DAY.
