Re: [Xtreme] AT&T threaten me..I think!

What do you mean by max rate and attenuation just don't fit together? Is something wrong with it?

The 2wire gives a max rate of 6652kbs with the attenuation at 41.4dB
I think the max rate should be much lower
The 3347 has a "max rate" what is it

2wires (for some reason) seem to always report higher than what they can achieve. Don't know what it is with the chipset but it always seems higher.

I would say in my experience the 3347 is probably right. 41.4db attenuation to 43db attenuation should have a max rate cieling of 5900kbps to 6300kbps max.

6500 seems a bit high for a 41.4db attenuation.

Yes, if your loop length were actually 14480 feet, it would be rather long for a 3 mbps connection (and the "bridge tap" would also seem to be a bit foreboding. However, it is not unusual for an inexpensive (inexpensive compared to real DSL test equipment) DSL modem to report both of those things incorrectly.

FWIW, I think you are looking in the wrong place again. Your problem is the noise on your telco line, it does not really appear to be a "DSL" problem (although a bridge tap ...if there is one... could be a potential entry point for noise).

Yea...I was just snooping around in the stats..I have not given up on the telco line yet. I got someone higher up than the local supervisor taking a look at it. Hopefully should hear something Monday or Tuesday.

Yes, the 3347 attndr and the 2wire max rate are the same, different terms used to describe the same thing
said by goose1000:

Yes I think that figure is too high for the sync rate you have but the attndr figure contradicts that

I've found that the estimated loop length figures given by the motorola modems are close to the loop length figures given by att techs who have access to that type of info

Well I was on 1.5 before and had same disconnect issues as I am having now..I thought it would have been more stable connection but it did not matter by dropping speed.

if the attenuation numbers (from both sync readings 2wire, 3347) above are accurate from both modems I can tell you it's not 14,800ft. Both of those readings up there give me a max distance of 7800ft max. For what we consider perfect elite stats for the 13 states (6500ft or lower), he is rather low to have the upper level profile. If they are trying to sync you on the upper level profile with what you are telling me, then intermittent sync will be a common problem as upper level frequency shifting will become a problem.

With the attenuation numbers you posted earlier, that would be inline with the 6500kbps max rating I was at while ago.

Well I went back to 2wire for now, for whatever reason 3347 SYnc loss was over 50 times yesterday. Here are some current stats for my 2wire. David I`m sorry but I don`t really understand what your trying to say. Do I need to get AT&T to change something?

Current Rate: 3552 kbs 384 kbs
Max Rate: 7148 kbs 1056 kbs

What about my output power? Thought I read somewhere that it could affect Sync.

not necessarily, I have one here at the house that sits at 18db all the time downstream and sits at about 3db upstream. It kind of depends on wiring in a premise and external. Don't just say "Oh I am at 19.6db of power that's bad!" IF the DSLAM profile is set to max of 25.5db or (yes I have seen it) 30db of power 19.6 could be normal.

assuming they left you sit at the 3552/384 profile, that should have enough headroom to do everything the DSL needs to keep sync. Do you still lose sync at the nid/sni gray test jack outside?

I am kind of assuming you do, but in my trying to keep up with this thread I may have missed it.

Yes sync is loss out there as well.

based on the info you gave me via IM, I looked at it, and I was right about 7800ft.

I asked one of my peers to make some changes, see if that helps any of the modems any.

So far in the first 5 minutes I haven't seen any errors, so I don't want to call it good, but so far so good.

If that makes sense.

one thing I did frequently when I had dsl was that to have a cmd window that I ping yahoo or google...

I had this window open most of the time in a pc that I had that's turned on 24/7.

when I see ping times drop or stop, I check my connection and everything else...

for some reason, that ping window kept my connection alive in spite of dropped connections having used almost all of AT&T's crappy modems.

I'm not advocating this kind of practice but it helped me keep my sanity and not worry about it too much as I had other things to do.

AT&T tech came out this morning, spent hour up the road listening for static, he said he never heard anything. Meanwhile I plug in @ jack inside and NID and hear static..how can they not hear it, I can call a neighbor and they can hear it, but tech cannot.

did he plug in also from the hack inside the NID?
