Is it just me?

A break on the line would affect voice, Bill, eg no dial tone. Oddly enough, the ADSL would continue to work unless it was a huge break.

Lance · Mar 04, 2007, 13:38:43

Have you noticed whether it is worse when it rains or when it is quite windy? Either of those are often a sign of a poor connection to the overhead pole, assuming you have a overhead pole and not underground cables.

Although I agree with Rik, that would also affect voice.

old Bill · Mar 04, 2007, 13:47:58

Well its very wet and windy today. Does anyone know the no for BTs quite line test ?

Lance · Mar 04, 2007, 13:50:38

The number is 17070.

old Bill · Mar 04, 2007, 13:56:15

Thanks, Just ran the quite line test. Geting a hissing noise on the line not loud but in the background. Is this normal ? I dont know how quite the line should be.

Rik · Mar 04, 2007, 18:26:31

There tends to be some noise, Bill, depending on what sort of phone you're using, but it should be very much in the background. If it's noticeable during a normal call, then there's an issue and you can long a voice fault.

old Bill · Mar 04, 2007, 18:39:48

Sometimes there is noise on the line sometimes not. Have tried resync a fet times today over a period of time but each time the stats have just got worse. Up to about 10 days ago my line was holdong fairly steady but now my noise margin has gone up quite a bit and of course my synce has dropped big time.
Downstream      Upstream

Noise margin (dB)

To be honest I have lost all faith in BT and BB in general. If it was not such a pain I would go back to dial up. I have a Mac code from Idnet from a few weeks ago have not got to much longer to use it. I just dont know weather to Pay a high price for a fixed rate line with Idnet or just to join the cheap and nasty club.

old Bill · Mar 04, 2007, 18:41:56

IF (a very big one) my line stays stabe will the noise margins drop and my sync speed go up, or is it a lost cause now and about 3 meg all I get ?

Rik · Mar 04, 2007, 18:56:43

Afaik, Bill, IDNet would have to request that BT drop the margin. Your profile follows sync speed, but I am not aware of noise margin responding to the line conditions (except upwards, in an attempt to stabilise the line). If your margin did go down, your line would - according to everything you've said - become less stable, and the whole cycle would start again.

old Bill · Mar 04, 2007, 19:30:10

Well even with the higher noise margin the line fault is still flashing like mad. Looks like I will switch back to fixed rate. If that does not work I will go back to a piece of string and a couple of cups I will try fixed rate for a month or so and then maybe try Max again.

old Bill · Mar 04, 2007, 20:17:26

Just had a phone call, lots of background hiss on it. That bad had to hang up and try again

Glenn · Mar 04, 2007, 21:49:11

If you have a hiss on the voice side of the line report it to the supplier (BT?) they can then sort that, tell them it is worse when it rains. Once the interference is sorted, maybe the line will be more stable.

Well it sounds as though it's either a faulty line or a faulty filter.

It's worth adding, Bill, that if you do, don't mention you have ADSL to BT.

old Bill · Mar 05, 2007, 13:34:57

C/S reported fault to BT. BT are now running full line check. Just waiting for C/S to contact me. I know what BT will say, everything is within spec. They cant find a brokern line even if it is is danngled in front of them. If that is the case I will switch to a fixed rate line.

Rik · Mar 05, 2007, 13:38:30

Good luck, Bill, I'll cross everything for you.

old Bill · Mar 06, 2007, 15:25:24

Just had the BT man out. The only thing he could find which might be wrong apart from the line was my ADSL Nation filter Plate. He has now swapped it for a BT one and told me to keep a eye on the amount of errors I have on the line. With all the stats I have on my router can anyone tell me what I should be looking out for ?
Thanks

Well, those errors are mainly different to the ones I'm used to, Bill, so I can only guess.

Keep an eye on HEC down to Bit errors, see how the numbers fo. I don't know how long the router had been up, and the numbers only mean something relative to uptime, so post back at +24 hours and let's see how they've changed.

What was wrong with the ADSL Nation filter? I'd have a word, it will still be under warranty won't it?

old Bill · Mar 06, 2007, 16:56:55

Thanks Rick,
The router had been running about 1 hour. The BT chap ran a couple of tests and said that there were far more errors using the ADSL Nation filter then the BT one. I Will email ADSL Nation and see what they say.

Rik · Mar 06, 2007, 17:04:27

Those errors, for an hour, don't look significant to me, Bill. Keep an eye on it and post back after 24 hours and we'll have a much better idea. I've always found ADSL Nation stuff to be first-rate, so maybe you have a duff one? Certainly it's worth talking to them...
