Says so on oxfoddhire site.says December 2015 for cab
Cabinet 5 for that exchange isn't listed on that map, only cabinets 1,2,3 and 4 are, I think you "may" have got mixed up with cabinet 5 for exchange Goring (THGO) its very close to the Cholsey (THCLY) 4 cabinets.
Also that other red square below that other exchanges cabinet 5 is cabinet 4 of Goring (THGO), those two cabinets of that other exchange is down for December 2015.
Image of map with selected cabinets: THCLY Cabinets
that other cabinet on the other exchange is due December 2015.
*** Update ***
Another image of the map with only the cabinets for the exchange in question: THCLY Cabinets Only
you only get the 4 cabinets when you select the required exchange.
