150 Mbps, you're lucky. Here AT&T has to bond 2 pairs so I can get 25
Mbps. At least it's not comcast. I wonder how many pairs they could
bond. Is there a technical limit or is it just a matter of how many
they want to bond? As more people abandon landlines, that leaves more
capacity for AT&T to bond multiple pairs for internet customers.

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

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

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.
