Cash given to former telecommunications facility (8)
I believe the answer is:
exchange
This clue is a double definition.
'cash' is the first definition.
(thesaurus)
'to former telecommunications facility' is the second definition.
'given' acts as a link.
(Other definitions for exchange that I've seen before include "Bandy" , "Short conversation or argument" , "Give one thing and get another back" , "Barter; switch" , "'Swap, trade (8)'" .)
