Heathrow, Gatwick, Luton and Stansted all interface with IFPS/CFMU and NAS primarily with the EFPS electronic strip system. A DLA message sent from EFPS goes to both.
In recent days at Heathrow I would have loved to have had an ATSA helping us. They're sat right next to GMP, and yet are not allowed/unable to offer much assistance. It's ridiculous.
