Re: Cable?
There must be situations where the exchange is no longer "the focus" / centre of things. (especially on rural exchanges/buildings that are being designed out, of future network topology)
So potentially, the copper/alu line could be diverted/connected to an FTTC cabinet that doesn't take the same route, it takes a fork in its route and the resulting FTTC is actually further by cable (and outside its ability to offer FTTC) than previous ADSL exchange only - connected line. What's odd here is the line is getting near maximum 18Mbps*, so it seems likely an EO (Exhange Only) ADSL line.
Anyone know real examples (Postcodes) of this happening? i.e. Re-routes, where new cabling to FTTC is longer, than previous.
*Unless this is usual "upto" 18Mbps confusion (in terms of service) and not the actual speed the customer was receiving.
