Post your FTTC line stats & unlocking info

No problem. Below are the results from the pbParams command.

With those stats, it looks like the cab is just outside your house :D

Do you know how far it is?
 
It's about 50-70m away (at the end of the street) so not that far.

It's a shame I'm having problems with the actual service at the moment with speeds dropping as low as 200kbps earlier...and that was on the BT Speedtest!!! At least I can be certain that my end and up to the cab is not to blame. That's why this data is so invaluable.
 
I was gunna say looks like a 100 meter line, very nice stats, is the speed low all the time, or at a certain time?
 
With the recent speed increase announcement, and increased speeds showing on the BT Wholesale checker, what are people now seeing on their modems?

BT tells me:

Our test also indicates that your line currently supports a fibre technology with an estimated WBC FTTC Broadband where consumers have received downstream line speed of 58.8Mbps and upstream line speed of 20Mbps.

My question is this.

If I ring BT and ask to move to the higher speed, will I get more than the BT checker is saying?

How do you estimate the line length from the stats?

Is there a formula or table?
Click to expand...

Not so much a formula, from seeing lots of stats you can gauge the distance, it is a bit of guess work, but it's close. There are a few formulas about, all within a few meters of each other, even broad com have not really cracked it with VDSL yet, hence the 0 figure in line attenuation.

Take milanoChris, his line is not much different to mine, he has a nice line, looking at the upload speed, it will be a nice all copper line. he can attain slightly higher speed than me, but my cab is getting full now so crosstalk is going to come into affect and I have seen affects of this. My line is 300 meters I would say his is closer to 400 meters.

my exchange is fibre enabled, but when I try to get fibre it says it isn't available in my area WTF!!!!!!

You could be on a EO line "exchange only" which means your line does not have a cab and goes direct to the exchange.

Or BT simply decided your cab wasn't worth doing.

They're the only bits that really matter to me ;)

So, yes, they look very good :)

You're bouncing off the rev limiter mate :D


I really must unlock mine and have a butchers, but I think I'll wait until my upgrade has gone through.

Cheers for that. I did have virgin 50 Meg in the beginning until last October when their service went really bad. But this infinity with this speed,jitter and ping is compared to none...

hitting usenet with 76.5 Mbps/9.6 MBps at the minimum, i once saw it reaching 10 MBps :D
 
Thanks to OP here are my stats is this good for my lenght to cab ? (I think 750 meters)
