I would be very wary of Verizon's plans...
Even though they might say you get "10-15Mbps" , if you live in the Southern California (esp. LA) area I can pretty much guarantee your speeds will plummet during high traffic hours...
I have their Turbo plan (4.0-7.1Mbps) which is their "2nd best" now and....let...me....tell....you...IT IS HORRIBLE. I would avoid Verizon like the plague. During the daytime, my internet is barely considered decent (at the best of times it is around 3.8mbps) but when I get home from work on the weekdays and want to actually surf the web, the internet comes to a crawl at below 1.0Mbps.
So heed my advice and be very careful with VZ...
Maybe sign up for a month or two and if you get consistent speeds for that full month with no issues (speaking of which, if you have issues, don't expect any help from Tech Support) then maybe sign up for a contract...
As for me I'm going to give 'em the boot as soon as my contract is up!
Well, I've had Verizon DSL for years here in the Lower East Side, first at 3mbps and now 7, and though I've heard of the post 7pm slowdown,s I've never experienced them myself, so I'm not quite as fearful as you. My speed and conection has been pretty rock solid. That said, I didn't even know that DSL could reach such speeds, so I'm a little skeptical. If I can only attain, say, 10mbps, it wouldn't really be worth the cost.
I agree with Hippocrite. I have been having an issue with my dsl speeds for 17 days now. Tech support has not been able to resolve the issue. I have had my posts moved from here to a special forum for employees to look at . They have contacted me and I have been working with them but i still have no resolution. I have the 7mb service also but after 7pm its under 1mb and I live in Los Angeles area also.
I cannot comment on the advertising. I will comment on the chances of a user actually getting 15mbps. While ADSL2+ is significantly faster than ADSL, that advantage is significant only if your copper pair is less than 2 miles long. The copper pair length to achieve 15mbps is limited to about 2000 feet, so unless you are very close to the Central Office, it isn't going to happen.
15Mbps up to 2000 Ft
10mbps up to 1 mile
5mbps up to about 2 miles.
at 2 miles and beyond, the advantage over ADSL is only about 10%, however ADSL2+ may still provide usable service up to about 3 miles.
This all assumes the copper pair is in good condition, and that is unfortunately a big if for many Verizon customers including yours truly (which is why I am now a FiOS customer).
There is a graph that show ADSL versus ADSL2+ performance versus copper pair length at
Upgraded 11/16 to Verizon 7.1 to 15 Mbps DSL plan. "666" Exchange UWS
After making calls to Verizon, Verizon Exec Help , then speaking with Level III tech service, I'm told my DSL line is "capped" at 10 Mbps. The next day, I received a call from Level III tech telling me that by Jan 2012 I can expect faster speeds.
Noticed - after calling tech to "tweak" the line, I'm now running slower DSL test speeds: 9.1 Mbps vs. 9.67 Mbps. During this time XPPro also upgraded itself. Possibly "updates" are slowing speed? It'd be great to have as close to 15 Mbps as possible. When I had 7.1 Mbps DSL I was getting 6.7 Mbps on Speedtest.net = 90% throughput. Now with 9.1 Mbps out of 15 Mbps it's more like 60%.
I wonder why Verizon must cap DSL at 10 MBps? Slower speed insures stability. Why not remove the cap and let me see how stable it goes? Possibly my lines at 15 mbps are fine. Especially since FIOS is not available here until our next lifetime...
10562 Kbps / 1067 Kbps
Even if Verizon did remove the cap, your line is pretty much maxed out. That's all you're going to get out of it. As long as it isn't dropping out or showing packet loss you should be fine. Otherwise, Interleaved mode would have to be enabled for some error checking. A tech won't be dispatched by Verizon, as more than likely they will just set you back to 7.1Mbps...
How is my line maxed out? Like to learn more about what's going on here. Thanks.
Replacement modem arrived. Speed averages 9.3 Mbps down / 0.9 Mbps up.

It's something you need to find by looking at the statistics as a whole. I'll give you a quick rundown. The margins are often a key player in what you can really get. The margin measures the ratio between the actual DSL signal, and the noise present on the line. It's a factor of line condition and equipment settings/tolerance, but with DSL you do not want to go below 10dB. You can run as low as 6dB but any lower would give you a lot of trouble with sync.
Attenuation is often a key of how much you can get, though it is more or less not as useful of a measurement. It's great for finding out your line length in an approximate form or for spotting line trouble, but other than that it doesn't show a whole lot about what speeds can be gotten. You can have really high attenuation and get high speeds, or you can have very low attenuation (which is ideal) and get barely more than minimum speed due to noise. On normal lines, it should help clue into an approximation as to what speeds you will be able to get on a line. Your attenuation suggests you're just shy of 2 miles wire length of cabling.
Transmit powers are what their name says it does. It is a measurement of how strong each end has to transmit to establish a connection at a certain rate, so it's a make or break situation. There is no true ideal range, but it is best to have a line running clean enough as to not transmit loud enough to cause cross talk to occur with other lines. The DSLAM in your case due to the matter of things actually has to transmit at a high power to obtain a 10Mbps sync. 22dBm is more than likely the max on the gear.
It's a matter of knowing a bit about ADSL Technology. As distance increases, noise will increase, signal will attenuate, and error checking will become more crucial. As lines deteriorate, attenuation increases at a higher rate, max distance decreases, and noise floors increase. Chances of crosstalk (a factor of noise) also increase.
