Have noted in my particular area, N.W. N.I. that CSP's are very rarely fitted with OR (or their sub-contractors) FTTP installs with UG feeds but virtually always on aerial feed installations, wonder what the "official" policy is?
I assisted the (very) young OR engineer with my daughters UG feed FTTP installation recently (he was more than glad of the assistance), he did fit a CSP box and related that it was policy but very few of his colleagues bothered, got the impression if I had not been present he may well not have bothered either!
