<p>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.<br>

<div>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.<br>
</div>
<div><br>
</div>
<div>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.</div>
<br>
<div>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.<br>

<div>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.<br>
</div>
</div>
<div><br>
</div>
<div>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. ;)<br>

They're bonding 2 <br>

bonding. I understand that one pair will carry some

the other pair will carry some. But one thing I
didn't find out was <br>
whether or not anything will change between the wall

modem. Is everything done outside or do they have to
come inside? I <br>
currently have a 2 conductor cord connecting my modem
to the wall jack. <br>
Will that have to be replaced with a 4 conductor
cord? Do they install <br>
an extra box outside or inside? I guess all will be
answered on the <br>
18th when the guy is scheduled to be here. I'm
really curious how this <br>
works.<br>
