Narrative:

There were 3 cle inbnds and 1 pit inbound coming into our sector. Buf sector was working the aircraft. I called to get control down on the aircraft and they gave me control for descent with respect to medium large transport X. We had all the associated pvd's on our scope and therefore I didn't see any need to relay to the radar controller that we had control for descent with respect. Subsequently though, he descended an small transport Y to the same altitude as the medium large transport X with 2.5-3.5 mi of latitude sep. To prevent a recurrence of this same type tell the radar man verbatim what was coordinated.

Title: POOR COORD BETWEEN DATA AND RADAR CTLRS, SMT DESCENDED TO SAME ALT AS MLG WITH LESS THAN STANDARD SEPARATION.

Narrative: THERE WERE 3 CLE INBNDS AND 1 PIT INBND COMING INTO OUR SECTOR. BUF SECTOR WAS WORKING THE ACFT. I CALLED TO GET CTL DOWN ON THE ACFT AND THEY GAVE ME CTL FOR DSNT WITH RESPECT TO MLG X. WE HAD ALL THE ASSOCIATED PVD'S ON OUR SCOPE AND THEREFORE I DIDN'T SEE ANY NEED TO RELAY TO THE RADAR CTLR THAT WE HAD CTL FOR DSNT WITH RESPECT. SUBSEQUENTLY THOUGH, HE DSNDED AN SMT Y TO THE SAME ALT AS THE MLG X WITH 2.5-3.5 MI OF LAT SEP. TO PREVENT A RECURRENCE OF THIS SAME TYPE TELL THE RADAR MAN VERBATIM WHAT WAS COORDINATED.
