Forgot to mention.  You might not be connected directly to the CO.
There may be a "point of presence", near your location, where your phone
line terminates.  You'd then be connected back to the CO via fibre.
This is common in large office buildings etc.  Things get a bit more
interesting, if you get your phone/ADSL service from another provider.
In that case, you'd be physically connected to a Bell office, but your
provider would have equipment located there, which connects to their system.
