If he's not at 3Mbps yet, he can send me a PM. I'll get someone to turn his speed up to the max both his line and package support on the spot. Best to reach me for that during the evening though as that's when it'll get done the fastest.
Consider this:
Pretty oddball speed for a DSL line, don't you agree? This line was originally rated for 1.5Mbps due to it being estimated being 17,000ft from the CO per their database (The engineering diagrams I've seen however show a significantly longer and oddly routed loop making a long haul ALL THE WAY to the CO. There's a remote 500 feet from the business that could be tapped into but isn't). I requested for it to be locked at 3Mbps/768kbps and it held but with a noise margin of 6 which is bad. Had it turned back down on the spot to 1792/448. I then had the speed set to 2112/640kbps, not a normal profile for a Verizon line and it's taking it without an issue, and we kicked the line between these speeds all in a matter of a few minutes. I'm getting it boosted to 2640 downstream if the line keeps performing like this. No waiting, no mess if you've got the right contacts.
This is a Verizon Small Business DSL connection above. 60 year old copper and lots of legacy and HDSL-based T1s in the trunk, hence the boatload of errors (cannot reset counters without rebooting the modem,but I'm VNC'd into a machine at the business and others are on it) but solid none the less. Those errors were there just as bad as they are now at the 768kbps rates. The line's old, beat up and due for retirement but is a nice, low gauge pair which is probably why it has so much capacity in it. No getting around that but we're squeezing what we can out of it and bypassing the typical means of provisioning lines. Copper's as clean as it's going to get. The same CO this line comes out is the same one feeding the remote I get DSL from, and does have ADSL2+ DSLAMs in it. If there's extra capacity on one I'm also going to get the above line moved to ADSL2+ for some more comfort and to hopefully get some nice noise-squashing modes enabled for the port which allow dynamic speed adjustments without drops. The CO is FiOS-serving and does deliver GPON FiOS. The portion of the area the CO itself is located in however does not have FiOS. It's all South of the CO which is a very odd way to do things. What FiOS cabling is north of the CO is not hooked into anything and is very, VERY close to me.
Erik_VZ:
We haven't had any further connectivity issues with our DSL.
Though it only seems to occur every couple weeks... so I guess only time will tell.
I had emailed Verizon tech support about changing the DSL speed, but of course they said I had to call, and so far I have not got around to doing that.
It looks like we may soon be switching to Comcast, so I wasn't in any hurry to pursue the speed issue with Verizon, if we are going to be closing our VZ account.
On a slightly different but somewhat related subject...
Earlier this week we lost our main phone line for a day and a half (perhaps due to a lightning strike in the area).
It took a lot of arm twisting till Verizon managed to get our incoming calls forwarded to our rollover line.
They usually tell us that we are not their customer, even though we have been their customer for the last 6 years. 
Eventually (1 1/2 days later) they did come out and restored phone service on the main line.
Thanks,

That customer could be 500 ft from the DSLAM but if the cable to his serving terminal doesn't come from that DSLAM they can't assign him out of it. Good luck getting the line moved into the DSLAM then you'll have perfect 3360/864 numbers with no noise issues, otherwise the numbers look pretty good considering the attenuation.
The ASSIA system? Certainly am familiar with that. I had it shut off on that line and got the speed set manually (if it keeps holding it's going to go a little higher, though giving it some time) as the ASSIA Optimization system was killing the line too much before it got repaired and I re-wired the building with new cabling and split POTS from the DSL, setting it to all sorts of speeds such as 1221kbps down, 160kbps up during crutial times which is just bad for it meant to be on 3Mbps. I'm working on a latency issue with that line now, which seems to be due to the Juniper ERX or the ATM switch the line is feeding through. Only occurs when downloading which isn't out of the norm for that line, but sporatically it won't do that. Haven't had the time to sort through things to get that looked at but it works fine none the less. I'd rather keep it on the Juniper as it's a faster router over the Redback, but the Redbacks don't see that latency issue, but it's nothing critical. Just a performance thing. It's not like my line where the moment I get moved to Juniper it absolutely hoses up and quits working until I'm moved to Redback (I've had to get this done once on the spot). The remote I come out of along with the ATM switches inside of it are incompatible with the Junipers, and it doesn't matter if we re-program the ATM switch to play nicer with the ERX or if we warm boot the remote, doesn't fix anything.
What's funny is with this line, there are at least 3-4 remotes en-route to the CO. Three of those are Catenas which I bet you are demuxed down to T3s but fed by OC12 Fiber (probably a ring? I didn't see that part of the setup), and a Litespan which happens to be 500 feet away from the business. It's probably impossible to get moved to the Litespan, and I'd have to get the line moved to Redback if I ask for that. ADSL2+ is doable and can get the request put in for move from an Alcatel High Density DSLAM to the Ultra Density units in the CO, getting it done overnight but for now it's working fine. Going to see what I can squeeze out of it. Being the distance from the CO the line is, it's really performing like a champ.
Oh yeah, I had the speed kicked up again 
Today I called Verizon about the DSL speed issue.
I was pleasantly surprised, I was only on the phone for maybe 10-15 minutes.
They put the speed back up to where it should be.
Running a speed test, it's now around 2.8Mbps / 700Kbps.
Right now it looks like we may be sticking with Verizon for a while, at least till our contract expires.
Thanks,
K
