10Gbps over crumbling COPPER: Boffins cram bits down telco wire

Re: not round here

A long run of copper between you and the exchange is actually perfectly normal - indeed, better than some people are stuck with: back before privatisation the GPO was using aluminium for a while.

The key thing, though, is that the copper will go from you to a very close DP (distribution point: in blocks of flats and similar, a little grey box on the wall somewhere), then almost always from that to a PCP (Primary Connection Point, usually a green cabinet on the pavement) and on back to the exchange. BT's "Infinity" connects a piece of fibre at that PCP level, which is much closer to people than the exchange.

Until FTTC, *every* line was copper 'all the way to the exchange', unless you were unlucky enough to have 70s cheapskate aluminium instead! (Or, in a few unlucky cases, you shared that piece of copper with someone else thanks to DACS, a 'pair gain' system.)
