Portugal, Lisboa ACC/APP
As in OZ, both frequency and phone are operated by a VCS touch screen - one per physical position but due to be soon replaced by two per physical position in the new OPS room
Two kind of headsets currently in use : the older one's (my favourites) of unknown brand - due to long usage they've all lost the stickers with the manufacter information, the most recent ones are Opera from Silicomp.
I was in Maastricht this ear and the Imtradex Headsets model Airtalk XD seemed very nice ... I'm waiting for a couple to test them in the OPS room ...
Imtradex developed this model togeher with ATC and is now the suplier for DFS.
I'll post my impressions after the tests, meanhwile
