Re: Need to switch between Interleave and FastPath? Part 2

reply to Moley
@Moley: If you stick with Interleaved the line speed could probably be pushed higher. It seems your speed is set for 7.1 but is either optimized or has synced lower than it should have. If you'd like FastPath though, you're good to go. Just have Verizon set the line to 5Mbps or leave it at that optimized speed. It should be fine.

@Meez: Try performing the NID test if you haven't already done so. You could probably keep FastPath if you can prove that there is a large enough issue inside the home and Verizon's copper is in good shape. For your distance I'd expect a Megabit to come out of that. Verizon could also come out to see what they can do to fix up the line to have more capacity, too. I'd do that first, being myself and biased towards performance with reliability.

@zorrtwice: Your stats are fine. If you were bumped off of FastPath, there isn't much of a reason for you to be bumped down. Your line has plenty of capacity for higher speeds, like 7Mbps...

@vultage: You might be able to slip by with 3Mbps without much of an issue, as long as you stay on Interleaved. I wouldn't try 3Mbps with FastPath though. Most likely, Verizon will set you to 1.5Mbps where you have room for Fast, or you'll be set to 3Mbps but optimized down to about 1.7-2.2Mbps where you might have enough room, still for FastPath. If ADSL2+ is possible that would give you a little more headroom.

@Jesuguy: You had FastPath and speeds close to 3Mbps on that line at one point, from what I'm reading, correct?

I would like to switch from Interleaved to Fast Path since myself and another person in my home are avid gamers. My DSL plan is the 1.5 Mbps Down/0.3 Up, yet as of 3 days ago my speed got bumped up to 2.9 Mbps Down/.8 Up, which has never happened. In fact I had Fast path before but I called Verizon and they replaced a DSL router with another one since that one was dropping our computers (not the DSL) too much and the replacement router was droing the same too, so I got another replacement. I come to check my path and its back down to Interleaved. When I did have Fast path I never had a problem.

But I just want to confirm if I can switch again:

Thank you.

Here are my stats. I'm also curious what speed I could qualify for if I upgrade. I'm currently on a 1 Mbps down plan. Verizon will only allow be to upgrade to 3 Mbps down though their website. Thanks!

i definitely need to be switched to interleaved. i should be getting 1500, but i'm only getting 700. my margin is really low.

Figured I'd post to see what you guys think, I think I should be provisioned 7/1 but I guess this is all I can get

Thank You for the reply. I'm going to move the modem to within a foot of the antique gas discharge tube suppressor, and I am adding a DSL splitter right where the line ties into the suppressor instead of using a DSL filter on the end of a 5' stub to my modular distribution block.

Other than getting a NID installed (tech says the line is too short to add a NID) i think that will do all I can for the up link. Two more questions.

1. What do I have to do to try fastpath?

2. Do I need to replace the gas tube block with anything better?

reply to mcdonn_3422
I honestly would say that if you can get the upstream running a little better, you should be good to go. Either way it should be fine from the looks of things.

How do I run my transceiver stats for my Verizon dsl westell 7500 modem?

reply to Smith6612
I just had and some line maintenance done. End result was getting my line re-provisioned, and the cap moved from 1.5 to 3.0. Sync is stable and I am getting reliable service at 2.88Mb/s. I am still in Interleaved mode and was wondering if my line could support FastPath. Stats for line with a Westell 6100 modem are as follows:

So what do you folks think? Is it Fastpath worth a try?

Thanks for your time.

reply to Smith6612
Well thanks for your response.

reply to exclusive213
If you want to keep 7.1Mbps you'd be best to stay with Interleaved. The line's running fine now but it might develop issues pushing it farther. The upload is missing 64kbps so that might be worth checking into.

I was hoping to hear from you guys if you thought it would benefit me to switch to FastPath? Thanks in advance!

reply to Smith6612
No options for interleave. It's just fastpath, interleave and one for the auto optimization.

reply to Smith6612
It's probably Verizon being cautionary, as the Adtran card itself appears to allow it (in fact the card allows download speeds of up to 32 Mbps). When I was on the Alcatel 7300 ASAM, I was doing 15 Mbps on FastPath.

reply to tim_k
By any chance, does an option exist for changing Interleaving depth? I'm curious if that would be a workaround. I find it strange that a Fast option would not be available, though I'm curious if it may be a limitation of the DSLAM (>8Mbps = Interleaving) or perhaps Verizon being cautionary.
