Risk my 6 Meg Profile for FASTPATH?
First of all, are the rumors true -- can one lose their 6 meg profile by requesting to be switch to FASTPATH? If so, should I risk making the request?
I don't play online a whole lot, so besides that, will I noticed any quantifiable differences between fastpath and interleave? I've uploaded my stats... I'm sure I can handle FASTPATH.
Unfortunately, I upgraded to the latest SpeedTouch 516 firmware like and idiot and now I've lost DMT access and OrbMT isn't fully functional.
Also, given my stats, why am I syncing at 768 and not 800? Is that a sign of some deeper underlying issue?

You're on an IKNS remote which will never show fastpath even if you're on it. As for the sync those be the bugs of the remote because the upload SNR is always 6 no matter what. Sometimes my 516 would sync at 800 other times it wouldn't or you could just be on 768. Search for IKNS remote for a lot more info.

Re: Risk my 6 Meg Profile for FASTPATH?
Assuming you are on interleave and it's not just the IKNS bug (which it probably is), it's a question of throughput vs. latency.
Changing you to Fastpath would require Bell to change your profile. If you're synced higher than 5 mbps and Bell has to mess with it, there's a strong change you'll get reduced to 5. So yes, that does definitely happen.
Decreasing latency will only really have a noticeable effect on latency-sensitive applications. If you game online or use VoIP/videoconferencing, and if you experience problems with these related to latency, switching to fastpath could help you. If, however, you don't do these things, it's probably worthwhile to stay on interleaved with the higher throughput for now, so that you can achieve a higher download speed in bittorrent or HTTP downloads.

Do a trace to see if you're really on interleave.

I did a tracert last week, at it was about 20ms higher... so it must have been the route at that particular time int point.
Anyway, it looks like I not AM on fastpath.

uhh, you mean you ARE on fastpath. you wouldn't get ping like that on interleave. it'd be more like 50ms.

Re: Risk my 6 Meg Profile for FASTPATH?
I somehow have a feeling you ARE on fastpath. I've seen in these forums some of the remotes have a problem differentiating the request.
Someone correct me if I'm wrong, but rule of thumb suggests if the first hop is under 35-40 mS, you're on fastpath. Interleaved is something closer to 50+ mS for the 1st hop.

15ms is definitely fast path. Interleaved is 30+.

STN @ 2nd Nov 12:35AM:
Re: Risk my 6 Meg Profile for FASTPATH?
What they mention is in practice generally true. The latency you're seeing should be fine for your uses. On certain hardware with fast path you can get as low as 6-8ms for the first hop, but it's splitting hairs compared to your ~15ms latency. And if you are on an IKNS remote right now you won't get any better than what you are seeing now.
Interleave profiles with high interleave depth settings will have 30+ ms first hop latency, but you can also use interleave with low interleave depths which can run at much lower latencies like 15ms.

Re: Risk my 6 Meg Profile for FASTPATH?
Ahh, I see. I don't think they let you make those kinds of configuration requests. There are fixed profiles and that is all the peeps on the phone can pick from. I believe the interleave profiles have a medium-high interleave depth, and then there is the fast profiles. A "low interleave depth" profile would not be one of their standard ones.

STN @ 2nd Nov 12:50AM:
Re: Risk my 6 Meg Profile for FASTPATH?
Or get an ADSL2+ "fast" profile. ADSL2+ does not specific a fast path in the standard so it ends up being a low interleave depth interleave profile. That could be one solution.
I don't know if they have one, but that would be what you want.

pnjunction @ 2nd Nov 12:52AM:
Re: Risk my 6 Meg Profile for FASTPATH?
Shortly after I was activated in downtown TO Bell switched me from fast path to interleaved and my first hop went from 9ms to 32ms. This ~20ms difference is typical from what I've seen around here.
I've never heard any talk of variable interleave depth with Bell ADSL1, if they have control over that it's either defaulted to some value or set by them but I've never heard of them saying anything about it.

Idk. Do the phone reps ever allow you to request certain speeds/profiles? Or do they not allow those types of discussion.

STN @ 2nd Nov 12:55AM:
Re: Risk my 6 Meg Profile for FASTPATH?
Interleaving by definition has variable interleave depth, in the standard. As for Bell's interleaving you are probably correct in practice. They possibly have a single setting they use for all interleave profiles. It's a value that is set by them.

Re: Risk my 6 Meg Profile for FASTPATH?
Don't you have a lot of corrected errors on your line? Decreasing interleave depth reduces the ability to correct errors. So you may not want this as it may turn some of your FECs into CRCs.

I'm on FastPath, i might like to evaluate 6016/800 Kbps Low-Depth Interleave
but i doubt being with a 3rd-Party ISP this would be possible at all - and even
if it were, there's only one Bell worker here who i can trust with my telephone
number for such a manual profile switch.
Would you say it's worth a try? Should i disturb him with my fancy request?...

does what you said mean that you know somebody at bell..if yes can u tell him to change my profile and increase it.

Here's an interleaved tracert to the same host so you can compare.... Notice the 2nd hop @ 46-71ms.

Re: Risk my 6 Meg Profile for FASTPATH?
I have both IKNS and Globespan remote DSL lines in my house.
The Globespan has a min 9ms first hop.
The IKNS (which is set to fast profile on Bell's end) always shows interleaved on my side. With the 2wire, it is full 45ms first hop and with ST516 it is 17ms first hop.
Nothing I can do about it. I just use the Globespan for my gaming.

Really eh, that's interesting.
I'll probably end up starting a new thread, but out of curiosity, can you post your stats for the IKNS remote. Do you ever have disconnects on the IKNS line?
My modem seems to reset itself every 3 days or so, sometimes even sooner. Teksavvy believes that there's noise on my line, but as far as I can tell, my stats are near perfect.

Re: Risk my 6 Meg Profile for FASTPATH?
Bell has a 6016/800 Kbps fast path profile, even when connected to IKNS. Bell will even tell you it is fast path if that's what they set it to. Even if it really is some form of low depth interleaving, I believe it's really a non-issue. The interleaving delay/depth is reported by 2 different models of modems that I have as 1.00ms, whereas I've seen this delay set to 0.25 on "real" fast path lines on old, regular Alcatel dslams.
an interesting note about interleaving... when I was on 2496/800 intreleaved, my speedstream 4200 would report an interleaving delay of 4 or 8 ms depending on the connection and my 2wire modem would always report a delay of 16ms.

I left teksavvy because of this remote, my line was close to perfect and everything would be fine for a few months then all of a sudden I would start getting disconnects, line drops randomly for weeks at a time. Then everything would go back to being great for a few months and after that just rinse repeat. I tried 4 different modems. I got fed up, I had techs out here doing all sorts of nonsense without any real solutions. It was all so damn random, I hate this remote.

When was the last time you tested this. The fast profile 45ms first hop should be fixed now. That is assuming you are still on the "fast" profile (yes, I know it shows interleave). There shouldn't be any difference now between different modems.

So you've left Teksavvy, or DSL all together? Becasue unless you switched to primus and were lucky enough to be put on their remote, I don't know of another DSL provider that you would not experience this issue on.
My experiences are very similar, if not identical to yours. I've had a few techs come out over the past couple of years, and every time, they commented on how great the stats look. If what you're saying is true then I guess there is no hope for me after all.
I do remember someone one the forums here saying a while back that if you're too close to a remote, you may experice issues becasue of the proximity. Not sure how far this is true...

Yes, it was a long time ago. I just checked again, and the first hop time is all over the place on the IKNS remote from 14ms and upward (Bell server on first hop) using a 2wire. I guess it is on lowest interleave depth or close enough too it.
I am not going to bother testing it with 516 using teksavvy login right now.
I know my dad's IKNS DSL line first hop time has been fixed with 2wire for some time now.
And for anyone else wondering about the line, the line stats are nearly perfect and I never had issues with disconnects on the IKNS remote using any modem.

It sure seems like if the attenuation is in the teens or single digits the dsl has problems that it should not have
I've even seen suggestions that a microfilter be used because the dsl signal is too strong
