Hmmm. 45,000 circuits per day. I estimate (*) that to be 1,000 cabinets per day, so we'll have switched over in the course of 2 months.
(*) Estimation: Current take-up is around 15% of properties passed; 90,000 cabinets and 27,000,000 properties makes for 300 properties per cabinet, on average. 15% of 300 would give an average of 45 circuits per cabinet. That means 1,000 cabs per day being converted; with a finger-in-the-air guess at 50,000-60,000 converted cabinets.
