Sprint had made the following error....

They had Fastpath turned on, but were setting my provisions on the Interleaving section still, instead of the Fastpath bitrate section. By default, if they don't set numbers in the Fastpath bitrate when they turn it on, it goes to 8MB/1MB.

Thanks to DSL tech for helping me understand this and explain it to my ISP so they could get it fixed with Sprint! ]]> http://www.dslreports.com/forum/remark,12740400 Tue, 22 Feb 2005 16:08:30 EDT http://www.dslreports.com/forum/remark,12739626 joaks001 : DSLtech,

Whats the difference between fastpath and Max Delay?

My ISP called Sprint and Sprint said that my profile is now correct but Im still connected at 8000 down and 768 Up. Ive reset my modem and still the same. My stats are still crazy too. The Sprint people say it may just be a wierd thing caused by the Fastconnect (of course they would say that). Any ideas?

I have a Zyxel 645 A....Im searching now to see if there is anyway in command Interpreter to force a lower connect speed.....no luck as of yet.]]> http://www.dslreports.com/forum/remark,12739626 Tue, 22 Feb 2005 14:34:34 EDT http://www.dslreports.com/forum/remark,12738743 joaks001 : DSL Tech, thanks so much for the help. The engineer that I deal with at mounet called it in this morning and it should be fixed sometime today. As far as them shutting off fastpath, I don't think they will. If they do, Ill just email mounet again and I bet they will open another ticket with Sprint. At under 5000 line feet from the CO, I don't see any reason for them to deny fastpath. My previous stats were excellent based on the FAQ in the Bellsouth area in regards to Noise, Attenuation and Line Capacity.]]> http://www.dslreports.com/forum/remark,12738743 Tue, 22 Feb 2005 12:44:00 EDT http://www.dslreports.com/forum/remark,12738454 gh4456 : You must understand that the OSI model is a theoretical model and in fact we use the TCP/IP suite of protocols. Yes it does have error correction built in, and interleave is an added part of the error correction. Interleave is not a term Sprint has come up with, but was decided upon by Lucent, that it would make for a more stable network. ]]> http://www.dslreports.com/forum/remark,12738454 Tue, 22 Feb 2005 12:08:58 EDT http://www.dslreports.com/forum/remark,12738000 Hobyboyz : Hey DSLTECH I have one question for you about Fastpath and Interleave. Maybe you can get an answer for me or us on this issue from one of the engineers. Its my understanding that interleave is turned on for error correction purposes. But what I dont understand is why? There is a model set in place on systems called The OSI Model that takes care of error correction of network packets. To get into more detail Layer 2, Data Link, detects errors and Layer 4, Transport Layer, corrects errors of network packets. So, with this why have interleave turned on if the OSI Model is already taking care of this within a system? If the Interleave slows down a packet time then it should be off and fastpath on. The error correction would be taken care of within The OSI Model.]]> http://www.dslreports.com/forum/remark,12738000 Tue, 22 Feb 2005 11:11:38 EDT http://www.dslreports.com/forum/remark,12737306 gh4456 : Alleyman,

His account is not handle by the same department as Sprint Customers. He was allowed fast path by the techs who handle the ISP's account, so you shouldn't have anything to worry about.

DSL Tech]]> http://www.dslreports.com/forum/remark,12737306 Tue, 22 Feb 2005 09:39:26 EDT http://www.dslreports.com/forum/remark,12736774 Alleyman : DSLTech is a great source of information! :) But I'll relay some experience on my part. With Fastpath if you make ANY changes to your line, it will be shut off! I had that problem and now I'm stuck without it. Took me 2 years to get it turned on, had it on for a year, now it looks like I'll never have it on again.

In closing, don't make changes unless you REALLY REALLY need them if you have fastpath already.]]> http://www.dslreports.com/forum/remark,12736774 Tue, 22 Feb 2005 07:42:57 EDT http://www.dslreports.com/forum/remark,12735172 gh4456 : It all depends on how the actual lines are run from your nid back to the CO. You may be 5K arial ft, but 15K wire ft. Also, I do not know what specific agreement we have with your ISP. Most customers, we over provision, but your ISP may be different. If you are looking for a higher speed, just ask your ISP if you can get any higher. It may just not be loaded in the system.

DSL Tech]]> http://www.dslreports.com/forum/remark,12735172 Mon, 21 Feb 2005 23:14:20 EDT http://www.dslreports.com/forum/remark,12735103 joaks001 : Ok, thanks!

I emailed my ISP, they have been really good about getting any issues addressed. I just hope Ill get to keep my fastpath. The difference on game servers has been unreal.

Based on what you said, I guess 512 is about as much throughput as I can get, otherwise, wouldn't my speedtest be over 412? I thought being at under 5k feet, I could get more if ever wanted to upgrade]]> http://www.dslreports.com/forum/remark,12735103 Mon, 21 Feb 2005 23:03:41 EDT http://www.dslreports.com/forum/remark,12735038 gh4456 : Yes, It is an easy mistake as the entire provision for the DSLAM is deleted and rebuilt and if they don't enter a speed in for the upstream, then it defaults to 8000. Obviously you can't connect at 8000 (even though I have seen some 8Mx8M connections) so it connects at whatever speed it can handle.

You will need to contact your ISP to have it fixed =)

You may try contacting tech support directly, but you may get turned away, but then again maybe not, if you are just reporting that you provisioned incorrectly.

I guess the first question to come to mind is "Is that a fairly easy mistake to make?"

Thanks for the quick answer DSL tech. So what your saying is that the fastpath being turned on should not be directly causing the wierd stats then?

Would this be something I need to inform my ISP of? Or sprint?]]> http://www.dslreports.com/forum/remark,12735018 Mon, 21 Feb 2005 22:52:56 EDT http://www.dslreports.com/forum/remark,12734847 gh4456 : It sounds like your upstream was not provisioned correctly. Even though it is much higher :-) you still probably want to get it fixed as it will most likely cause you some headaches down the road. Once that is done, your noise margin and occupation should drop big time.

~DSL Tech]]> http://www.dslreports.com/forum/remark,12734847 Mon, 21 Feb 2005 22:36:19 EDT http://www.dslreports.com/forum/remark,12734584 joaks001 : My DSL is with Mounet.com, a small ISP locally in East TN that uses Sprint for it's backbone. I recently got FASTPATH turned on by asking the lead tech at Mounet call Sprint and request it. I have seen considerable ping time drops (from 100 ms previous to 60 ms to my gateway) but hadn't thought to check my modem statistics until tonight. Im seeing some really funny stuff. >>

Previously I was at:
Upstream Speed: 160 kbps (128)
Downstream Speed: 560 kbps (512)
UPSTREAM:
relative capacity occupation: 24%
noise margin upstream: 31.0 db
output power downstream: 10.5 dbm
attenuation upstream: 19.5 db
DOWNSTREAM:
relative capacity occupation: 16%
noise margin downstream: 33.5 db
output power upstream: 18.0 dbm
attenuation downstream: 22.5 db

Fastpath was turned on 3 days ago, and tonight after checking my stats again......

Upstream Speed: 960 kbps
Downstream Speed: 8000 kbps
UPSTREAM:
relative capacity occupation: 107%
noise margin upstream: 6.0 db
output power downstream: 12.0 dbm
attenuation upstream: 20.0 db
DOWNSTREAM
relative capacity occupation: 93%
noise margin downstream: 6.5 db
output power upstream: 19.5 dbm
attenuation downstream: 22.5 db


Im not having any resyncs or Disconnects, though I must be lucky based on the noise margin, as 6DB from what I have read is getting iffy.
I am only 4300 feet from the CO and I have a POTS DSL splitter at my NID with a Homerun going a whopping 2 feet to my Zyxel modem.

I ran a few speed tests. Before interleaving was turned off, I was getting about 450 down/120 up, now Im showing 412 down/780 up. I signed up for the 512/128, so thats definitely weird.

Any ideas would be greatly appreciated. I love my lower ping times so I really don't want to have fastpath turned off.....perhaps this is a Sprint issue?

Thanks,
