Actually getting 13Mbps, so updating to X2 sounds great, Dane! Wonderful news - good that I keep an eye on the forum. Stupid question, but do we need to run a second copper line?

Just out of interest - in a best case what real world speeds would customers get on the VDSL2 lines?

Is your profile consistently 13 Mb/s? If so, you should expect an approximate double of your current bandwidth with x2. Real world speeds tend to be less than the theoretical.

Concerning expected speeds with VDSL2, that is not an easy question to answer. The only way to truly find out is to wait for the deployment into your area and test it with a Sonic VDSL2 compatible modem if you are within the ~5,000 ft. limit. I doubt that Sonic would want to give you a VDSL2 modem outside of that range since any performance from that technology is theoretically restricted to within 1,500 meters (~5,000 ft.) Any performance outside of that range is going to coincide with the already available ADSL2 or 2+ standard. In other words, you are not likely to gain anything.

What is your distance according to Sonic's address availability query?

This is interesting. It is 4637 feet according to the website and up to 20 MBps. It used to be 5000+ unless I am totally confused, maybe something changed.

Support says I am not eligible for X2, because I am slightly less than 5000 feet away. :( I guess I have to wait for VDSL2 then. Given that I would have potentially gotten something around ~25Mbs with X2 given my current line speeds, any chances that VDSL2 will be as fast as that or faster?

I think that the support person was telling you to wait for VDSL2 before you try X2 because if your performance increases satisfactorily with VDSL2, then you won't need X2 and you avoid all charges to set it up and implement it. Basically, Sonic is trying to save you money if you don't need X2; however, you can always upgrade to X2 later if you just want the fastest speed possible over your line. That is what I am thinking of doing.

Since you are within the 1500 meters (~5,000 ft.) limitation, Sonic will contact you to exchange your current ADSL2 modem for a VDSL2 one.

Your speed is very unlikely to double at your distance. You could see a 25-50% increase realistically, IMO. The speed increase vs distance scale is not linear and drops off faster near the fringes. Who knows; you may get more than 20 Mb/s. It is just a wait and see situation.

Yes, this is correct. A single line of VDSL2 is $40/mo, no increase in service fee, whereas going to X2 increases your cost by $20/mo. Now in the end, you may WANT two lines of VDSL2, but it would make little sense and be very costly to add a second line of ADSL2+ and then move both of those to VDSL2.

Hi Dane, thanks for the answer. I appreciate that your team is saving me money. Either way, I'd be happy to spend an extra $20 for twice the speed.

Just to clarify because I am not entirely sure how this works:

X2 for me right now would mean we'd run a second copper wire or just use the existing and do something differently on the modem side?

Theoretically, you would offer VDSL X2? Because otherwise X2 ADSL2+ would give me 100% speed increase, which might be better than a single line VDSL.

And how long should I expect to wait for VDSL? Do you need a guinea pig for the rollout? :)

Thanks!

The bonding means that you will have two circuits, instead of one, coming from the CO that will be combined at the end user's premises via copper pairs. Instead of your single pair, you will now have two pairs combined and fed into your upgraded VDSL2 modem.
Theoretically, you would offer VDSL X2? Because otherwise X2 ADSL2+ would give me 100% speed increase, which might be better than a single line VDSL.
After the upgrade, you will be running off of VDSL2 technology--not ASDL/2 anymore. You will be able to add a second circuit which will provide your X2 paired bonding if VDSL2 (which is a single pair) is not sufficient.

As stated earlier, your performance will vary with distance. Since you are at the fringes of the 1,500 meter limit, you may not get double your current speed. VDSL does not offer linear performance; for, it drops off considerably near the 1,500 m range. That is why you can expect near ADSL2 speeds outside of that range; therefore no increased benefit for those further away. In a fairly liberal estimation, you can expect 25-50% increase at your distance; but, you may get more depending upon your line conditions and other factors. There is no way to forecast what you will get. You can only take an educated guess by relying upon VDSL charts to predict the max and min theoretical speeds.
And how long should I expect to wait for VDSL? Do you need a guinea pig for the rollout? :)

Thanks!
If I recall correctly, Dane stated last September or October that it would take 6 months from then to upgrade the entire network; so, it appears that they should have everything done by April 2015. Anyways, you should be notified when your location is ready for the upgrade. The question will be whether upgrades will happen at the end or during the completion of each area.

I believe that they do all of their testing among their employees in advance of the rollout. I'm sure that it's all done in the vicinity of their headquarters. Dane will correct me if I am wrong.

Yep, all about right.

All the X and V terms deserve some clarification.

Fusion is POTS voice plus xDSL technology at the fastest possible speed. For most members today, the equipment (port) they are connected to is an ADSL2+ one, capable of up to 24Mbps. (And all equipment is backward compatible too, so ADSL2 and old ADSL1 are also supported.)

X2 just adds another port, bonding a second line for roughly double the speed. For many customers this adds new life to a connection that isn't as fast as they'd like or need today.

"V2" is a confusing term I probably shouldn't use, it simply refers to the port being VDSL2 capable instead of ADSL2+. And as before, the new interface is (mostly) backward compatible too, supporting ADSL2+ and ADSL2, but generally not ADSL1. The new interfaces use PTM (packet transfer mode) instead of ATM (asynchronous transfer mode), so ADSL1 which requires ATM is not supported.

Fusion when delivered using VDSL2 can support higher speeds than ADSL2+, but is greatly dependent upon distance. Currently the fastest real-world speed we have seen is 80Mbps on a single line. The customer at that speed has a prequal distance of about 1,100ft.

So a "V2" upgrade is a re-wire of an existing loop from an ADSL2+ interface over to a new VDSL2 interface. The monthly service fee will remain the same, $40, but we may have a one-time charge for the move.

So if you are on a short loop, less then 5,000ft, you are likely to obtain a better speed if we move you to VDSL2, at a one-time cost instead of a recurring one.

Then if you want to double that, you could "X2" your "V2" at that point, for those who want maximum speed and for whom the additional recurring cost of $20 monthly for the second line is worthwhile.

All make sense?

Did that 6 month timeframe include the U-verse package as well?
