RE: interleaving
AFAIK 6db is the limit but I could be wrong.

Don't pay more than 30 inclusive postage

ahh fair dos im not 100% my self i was just basing it on the fact BE* let you put adsl down to 3 thought vdsl would be same lol but nm ay

I ent even got 30 haha at this moment ive got a fiver to mi name till next weds then bills nick it straight back off me lol, like i say i only want one for 20 mins so ill most likely never get one i cant use one permanently because ive got LBO tv which has a vlan to port 4 on zyxel so i think i have to stick with zyxel i dont mind though coz its actually a good router just be interesting to get the info off one of the hacked modems lol

RE: interleaving
I would think the profiles are fully configurable so you could probably set 0dB if you were crazy enough.

Its perfectly understandable that Thales are not going to do that and would also be reluctant to go as low as 3dB because something as simple as one new customer getting connected to your local cabinet could make your line unstable.

When I was on Be I only chose 3dB to get better upload, I would tweak the downstream to 6dB on the modem itself as 3dB became unstable as more people around me got ADSL.

hmm same here so maybe so,

On the subject i emailed LBO last night to see if they'd lower me down to 6

this is current status

noise margin upstream: 8 db
output power downstream: 1 db
attenuation upstream: 0 db
noise margin downstream: 8 db
output power upstream: 10 db
attenuation downstream: 23 db

so looks like they haven't done it yet :/

RE: interleaving
Well, I got interleaving turned down, but I have a funny feeling from what I understand Thales have slapped some FAT SNR on there. My ping is now 16ms from 44ms but speeds down from 39Mbps to 17.8Mbps. I cant imagine turning interleaving down doing this!?

ISP: Ask4 DR Speed: 39.5Mbit /9.90Mbit Ping: 16ms to bbc.co.uk Line Length: ~400m

Could it be related to a link outage affecting most people

I have a dedicated server, VM connection and my own being monitored by tbb and all 3 are showing heavy packet loss and jitter

RE: interleaving
Aren't you on the ZyXel? You should be able to see for certain what your current SNR is on that.

If its anything like ADSL then the max attainable rate is what you can achieve at 0dB SNR. So I would guess that my speed is going to be more like 100-110Mbit sync, putting me pretty close to 100Mbit actual usable speed.

The fact that the VDSL router manufacturers quote 100Mbit as the upper limit of VDSL I believe is that if you sync at the top speed, you get 100Mbit real-world throughput. The bummer being that we do not know what the maximum VDSL sync speed actually is to guesstimate if I am right.

This is the fastest I have seen so far, someone on Infinity only about 50m from the cabinet:

This is an interesting comment by someone though:
Quote:Before my upgrade my max attainable stats were generally saying 81000 down and 17000 up. After the upgrade I'm hitting 74826 down and 16877 up so a bit under the previous max attainable rate.
So maybe I will get closer to the attainable rate than I think?

Its annoying as a friend of mine is about that distance from the DR cabinet I am on. I keep plugging at him to get the service but he isn't willing to pay the increase in price compared to his Sky connection.
