For confirmation: https://en.wikipedia.org/wiki/Telephone_exchange explains that "central office" is a merkinism introduced by Bell. It also states that in the UK, the switchgear is a telephone exchange and the building the switches are housed in is called a telephone exchange (we Brits aren't very inventive where terminology is concerned). My vague recollection of uk.telecom is that the insiders' technical terminology was slightly different, but I don't recall how. I do recall mutterings about "directors" but they were obsoleted by all-figure dialling, but there was more to it than that. Suffice it to say that my small-ish town has a telephone exchange, not a central office. It is the termination point for voice and digital (over copper or fibre), but will probably always be called a telephone exchange. It's worth noting that there are plans to remove the POTS side of things and move everything to VoIP, at which point the telephone exchange will be purely digital. -- Paul
