Unless you are in an area that was recently built or went through a major upgrade, odds are high that your DSLAM still uses ATM for transport. |

If your modems chipset supports DMT or OrbMT, you can get the DSLAM chipset from that, although not the exact model. (The first pic is of an Alcatel A1000 SD, ADLT-E line card, does ADSL only. The second pic is an Alcatel 7330 (Broadcom chipset), EVLT-K card, does ADSL/ADSL2/ADSL2+/VDSL2)
As Bill said, you could call support but they probably won't be able to tell you the exact model either, only the type LT cards installed, and if it uses ATM or Ethernet aggregation.
I could post what the remotes look like too, if you like. |

| When the tech came out to install some new lines he said everything was new put in because this area has never had DSL but that does not really mean it will be a IP-DSLAM I guess. and yeah if you could post that i would appreciate it. |

These are what the newer remotes look like, an Alcatel 7330. (VDSL2, multicast IPTV) The DSLAM is mounted on the JWI/OPI (jumper wire interface/outside plant interface), power is to the right.
I'll post some of the older "walk-in-cabinet" styles when I find them. 
edit: An older Alcatel A1000 SD housed in a "walk-in-cabinet", with one OC3 feeding it.

Interesting little tool from that post there!
Embarq at the time, now CenturyLink(commonly referred to CenturyLag here in this area for some reason) recently installed a new DSLAM just to my northwest. That tool had some issues from what I could tell with what was what.
Me messing about with the DSL upload via FTP to remote server:
I am on 'FastPath', on the ADSL2PLUS mode. Length from DSLAM to the DSL line in house is very close to 3112ft (about 948 Meters).

You do have an ADSL2+ profile, but it's reading that you're on interleave, not fast path.
Are they trying to cripple VOIP or something, so you have to get a wet loop from them?? (I've seen most US ILECs do this, put people on interleave, even though they have great line stats) |

My guess is your DSLAM is oversubscribed and they limited profiles to 1.5Mbps. Your loop can certainly handle 10Mbps. Or their loop qualification database is wrong or outdated. |

| I have a dry loop but i don't think it would be oversubscribed we have only had DSL since the beginning of this year. I have been told the DSLAM is fed by copper but I know places that are fed by copper with faster speeds. |

If they have ADSL2+ line cards in the SLAM and you can only get 1.5Mbps because it's fed by copper, then CenturyLink definitely earns the, "Most Incompetent ILEC of Year" award. I guess they didn't read TR-101, or any other report.
I really feel sorry for you guys. My ILEC sucks too, but everything they do now is GPON based, they would never think to run some DS3s to a SLAM, not even ten years ago. |
|
| It is stupid that they will not offer at least 3 mbps. I wonder if the system information is wrong and they can really have faster speeds. |

Nice app there, I'd forgotten about it since the Cisco 678 days. 
Hmm, I get this from my 2wire 2700HG-D in the MDC:
stats
summary
Not sure what it means for my DSLAM, but it's a pretty good 7/896 ADSL connection.
The upload is not a concern as I rarely upload anything except images. I haven't rebooted it in ages, might need one to retrain at full specs...there's been a lot of work going on in the building lately.

That's the odd part. When i fully reset the ZyXel 660 to defaults, the tool was showing fastpath with green text and a green checkmark.

Ah okay, if you did get the check mark then you are on fast path, and judging by your latency, you are. |

ADSL (G.992.1) has a max download of 8000Kbps, so you could get the 7Mbps package, if they'll sell it to you. (I've seen 8000/1000 ADSL profiles here, but they were mostly test profiles which were eventually removed, some people still kept those profiles if their port wasn't reset or another profile applied.)
I see CL customers here on 7Mbps plans with ADSL2+ or VDSL2 profiles so I don't know what they can offer you in your area. |

I believe 0x39 is a Huawei chipset.
First time I've seen CL use T1.413 instead of G.DMT (G.992.1) too. And get them to put you on fast path!! |

That may be my doing, I can do my own protocol provisioning to a point with the advanced settings in the MDC. Some work better than others. 
I don't have CL as an ISP, it's a local outfit who also run their own regional DC's.
Here is a old post which outlines how the two are basically identical: » Clarification: T1-413 mode vs. G-DMT mode for ADSL
I've used both, as my old USR 9002 ADSL modem preferred DMT, but this seems more stable for some reason now on the 2wire. I can max the train on either though.

Ah okay.
Do they (your ISP) use CL for wholesale services? (to get the same coverage, using CL's remotes, COs, etc., but terminate their customers to their own DCs or exchanges?)
Or is it an unbundled loop and you're fed from a CO which they co-locate in? |
