<div dir="ltr"><div>So I went through this moving from Cox to CenturyLink, and pretty much as described, fairly painless.<br></div><div><br></div><div><tldr><br></div><div><br></div><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><div><div><br></div><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></div><div><br></div><div>-mb</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Aug 8, 2020 at 1:27 PM Jim via PLUG-discuss <<a href="mailto:plug-discuss@lists.phxlinux.org">plug-discuss@lists.phxlinux.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

I live, I get AT&T for my DSL service. I've signed up for

me why a technician visit is required for the upgrade. They're
bonding 2 <br>
pairs to supply the faster speed here. I've read up online
about DSL <br>
bonding. I understand that one pair will carry some of the
data, and <br>
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 jack and
the <br>
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>
