Re: IP-DSLAM FAQ

I currently have Regular DSL with the following stats off my modem:

Downstream Path / Upstream Path
DSL Sync Rate (Kbits/Sec) 8128 / 512
SN Margin (dB) 12.50 / 12.00
Line Attenuation (dB) 20.50 / 13.00
CRC Errors 495 / 2

I am eligible to get i believe the 12 or 18 DSL package that are now available in my area as U-verse has been turned on in my area. I game alot and have great latency right now being on a fast profile. If I upgrade to one of the U-Verse package can I remain on a fast profile or will I be regulated to a interleaved profile. Right now everything works fine and as they say if it isn't broke do not fix it.

If you can get IPDSLAM ADSL2+ U-Verse, you will keep Fast Path.

If you end up getting FTTN VDSL2 U-Verse, you will lose the Fast Path and be switched to Interleave

Hi DSLR, I had a question about IP-DSLAM:

Speed tests - I'm looking to get more out of my slow DSL line, and wanted to see some real speed tests from those with 3mb or 6mb DSL IP-DSLAM. I see that there's no ATM overhead so that must help some. Not sure if there's no PPPOE overhead too. With the 6mb connection, I normally would get around 5.12-5.20, and with 3mb I'd get around 2.58-2.60. Trying to justify the switchover if I could see how much of a speed increase people are getting in the real world.

Thanks a bunch!

When I had "normal" Dry Loop ADSL Elite, I consistently got about 5.1/5.2 Mbps down. With Dry Loop U-Verse ADSL2+ IPDSLAM Elite, I get a pretty consistent 5.5-5.6 Mbps down.

So there is still some overhead, but it is not as much as the ATM/PPPoE traditional ADSL product

I don't quite understand why users aren't "Over Provisioned" to account for Overhead -- instead of provisioning Elite service right at 6 Mbps -- provision it @ 6.5 Mbps, to allow for the Overhead loss, so the user experience ends up much closer to the consistent advertised speed. Oh well.

Thank you. While I would have expected closer to the advertised rate, that's still a sizable increase

Hi, I had one other question regarding this service:

Does it require an active home phone service like traditional DSL?

Edit: Well, I see you're calling yours Dry Loop, which would mean it wouldn't need an active phone service. The one that says available for me is:

"AT&T U-verse Internet Pro - D 3.0"

Is that the Dry Loop service? If all versions of this IP-DSLAM don't require an active phone line, this might be a good question to add to the FAQ for people.

No active phone line required.

U-Verse IPDSLAM does not require POTS/Active Phone Service

Then again, neither does traditional ADSL service. I had Dry Loop "normal" ADSL for a couple years before getting U-Verse ADSL2+ IPDSLAM Dry Loop
