So I went through this moving from Cox to CenturyLink, and pretty
much as described, fairly painless.
<tldr>
I had scheduled a CL tech to install me for new service a few
years ago, and we first hit the outside where CL ran their
cabling in. It was an ancient telephony distribution from the
90's, and I've never had a land-line in my house since owning it
in 2002. My house built in 95 at least used cat5 or like, so I
have 4 pairs to every room, so 2 pairs I need was just fine for
bonded DSL He ripped out the old block, removing the house
cabling but the one, and isolated the particular line we needed
to my office where the modem lives, added an approved jack,
done. Bonded dsl is 2x 2-wire channels, and they essentially
load-balance 75+75mbps channels. I have tested this to n-by
gigabit upstreams.
Phone only guarantees 2 wires are available, so telcos built on
this 100 years ago are a bit assed-out on passable high-frequency
modulation schemas in use for data and other things to move
beyond where they're at. DSL makes up for this, particularly
when double up on wires it gets better, but still unshielded and
prone to breakdown. Problem is mostly it isn't shielded, thus
capable of very high frequency modulation ala Cable/DOCSIS, so it
will never go much further than it has today whereas Cable scales
to gigabits with channelization and QAM modulation at 32bit rates.
VDSL tech is capable of roughly 75mbps per channel, and 2x of
these get you to around CL's bonded DSL limits. This also
includes your distance limitations to your local DSLAM, or
regional router that terminates your data that degrades this
eventually further you are from it, so it's a bit tricky. It's
been stuck here for years, and pretty much at life end. This is
why my cousin living half a mile from me can only get 75mbps from
CL and I can with bonded @150mbps here. Old crap network there.
Fiber, particularly Single Mode, gives you whatever to ~100GbE,
but depends on how your provider does low-rate Passive Optical
Networking (PON) today for residential fiber. Not quite the same
as a business data network, but any fiber is better than copper
networks.
Why Centurylink's only hope for the future is fiber vs. copper in
new builds. I like my 25yr old house still, so no fiber for me
ever. Unless I street cut my block for fiber myself, which I've
considered, just need to get my neighbors to buy into me as their
new gigabit isp. ;)

Ok. I won't complain if I have to go out and buy a 4
conductor phone cord.

My understanding of this is that they will activate the
second pair that is commonly used in the RJ-43 port in your
wall. This will allow 2 lines active to the device.
Changes inside might need to happen if your residence does
not have 4 wire (2 line) compatibility. (IE 2 pairs to the
jack vs 1 pair)

Where I live, I get AT&T for my DSL service. I've
signed up for an
upgrade from 10 Mbps to 25. I finally got someone there
who would tell
me why a technician visit is required for the upgrade.
They're bonding 2
pairs to supply the faster speed here. I've read up
online about DSL
bonding. I understand that one pair will carry some of
the data, and
the other pair will carry some. But one thing I didn't
find out was
whether or not anything will change between the wall
jack and the
modem. Is everything done outside or do they have to
come inside? I
currently have a 2 conductor cord connecting my modem to
the wall jack.
Will that have to be replaced with a 4 conductor cord?
Do they install
an extra box outside or inside? I guess all will be
answered on the
18th when the guy is scheduled to be here. I'm really
curious how this
works.
