Hi,
 New to forum so forgive if  this is not right thread for this
Some time ago I was with Sky talk (via BT). I started to get significant drops and re-syncs around March of this year.
After protracted tests + engineer visits + new modem I still had the problem
I decided to go back to BT  - - -reasoning I would take up the new "infinity" service which is due for my area (Chester central).
Well since I have been with BT I get the same problems and I have had visits from two engineers - - the last was a "boost" guy who saw there were errors on the line etc but felt it was a "line" issue. I have done the quiet line test numerous times!!) and can hear faint conversations from time to time - - - not every time though.
I also get a failed connection when dialling out ie: dial number and get the dial tone again. This can happen 3 times in 10 and can be recreated on either a cordless or corded phone.
BT are sending another engineer about the phone on Friday after the last one did not turn up as promised
I am advised about the possible charge if no fault is found but have recorded some clips where you can hear the crosstalk but dont know if this is "proof"
Anyone have some views/advice how I might proceed and if I am imagining things and wasting my time?
Sorry for the length of this but its driving me nuts

Hi and welcome,

Looking at your stats, there's nothing particularly noteworthy. The output power is a bit low, and that may be associated with the crosstalk. Error seconds are cumulative, so there's not much to be read into those figures, unless you power down the router and start again.

To be certain that the problem is external, you should really take the lid off the NTE/5 master socket (if you have one) and connect the outer to the test socket inside. This will eliminate your household wiring from suspicion.

The symptoms you describe (hearing other people's conversations sometimes, and dialout often failing) certainly suggest a line problem, and I think that the engineer coming on Friday should accept that. A lift and shift (to a different cable pair) might be needed, but you'll only get that after they've tried everything else. You really shouldn't be charged for investigating what definitely seems to be a faulty line.

It may be too late now, but you might have been better off if you had made a complaint about the voice problem (failing to dial out) without mentioning broadband.

[srt]

Thanks for the reply.
Well tbh the instances of the broadband crashing back from what was a regular and stable Downstream: 3.813 Mbps to 1600 odd triggered my original complaint.
The sync wont hold for more than a day or so - - noise margin increases to 15 or 16 db then pft:(
Its only after a series of elimination process queries to BT that I am getting the voice line investigated but as I say its not constant.
The router is in the test socket btw.

[Oranged]

The fact that the 3813kbps sync was on Interleave and all the other syncs have been Fast may be contributing to the instability.

[jeffbb]

HI
quote noise margin increases to 15 or 16 db then

If that is your DS going from~6 to 15 or 16db this would normally indicate that some very noisy  source has just shut down and the line should be more stable that difference of 9db is where your lost synch rate has gone .

can you run  Routerstats  and Graph the SNR margin ?

Regards Jeff

The cross-talk and failure to dial-out correctly issue . . . crossed-legs of two pairs, possibly.

As Mr Pag will say, there's nothing to be gained by speculation, it needs an OR engineer to resolve the fundamental voice service faults before the broadband service is considered.

Thanks for the replies
I appreciate them as they give me some confidence that I am not going nuts.
I am not able to get routerstats to work with the BT home hub 3
I will get back when I have had the BTO person round tomorrow.
Many thanks all

[burakkucat]

I am advised about the possible charge if no fault is found but have recorded some clips where you can hear the crosstalk but dont know if this is "proof" 

When the OR engineer arrives, assume that (s)he has not been provided with any of the details. So, whilst a mug of your tea or coffee -- plus biscuit(s) -- is consumed tell her/him the full details and start with the observed voice service faults. Don't forget to play back the recording of the crosstalk.

Please keep us updated with how thing progress.

[srt]

The engineer arrived at 8.30.
He advised me that there have been a lot of issues around my area with cables!
He also listened to the recordings I have of the crosstalk and confirmed that crosstalk was there. Though he could not hear it at that time.
I did give him a mug of tea
He swapped the D side cable  from DP to the cabinet and said that was the best he could do and was not promising anything.
He said it was more likely an exchange problem he mentioned broadband equipment.
Engineer left at 9.30
I have tried making a few calls and the connection failed several times as before!
I think it is safe to assume that the problem still exists if I get failed connections from either my corded or digital phone.
Oddly I get frequent "engaged" number when I try to use the quietline and asked to use ringback
I have emailed the results to the guy at BT who is overseeing the problem.

Hi Srt,

If you use an ISP who provides reasonable diagnostic records (such as one beginning with Z) you can ask to see the engineer's visit report.
This will help everyone gather sufficient evidence that your section of the network / exchange is in need of refurbishment.

Kind regards,
Walter

Hi Walter,
My isp is BT

[waltergmw]

Hi again Srt,

Well you could ask. Perhaps also researching how to obtain a MAC might also be a prudent move ?

Kind regards,
Walter
