I tend to agree with you about the problem of needing the two separate visits. And it especially hurts when it is all related to the G.INP mess.

There is, however, something of a proviso that needs to be built in:

without the EU having to play silly b***ers with their ISP to arrange a second visit.

a) When Openreach want to be able to take ownership of the fault, and have the ability to "route around the silly Bs at the ISP", the ISPs vetoed that possibility. The likes of Sky and TalkTalk don't want BT to be in any form of control of their subscribers.

b) The game of playing silly B's with the ISP is a consequence of buying a service from an ISP known to be lacking in the service arena. Their policy of making you wait N days before they bother to pay attention amplifies the problem with (a), which forced the back-and-forth via the ISP, making total delays longer and longer. When the service is sold with an underlying Openreach residential care policy that adds days onto each service request, you get what you got.

You're right that the problems aren't insurmountable - but it takes two to tango. If one party stays resolutely seated, the dance doesn't happen.

It sucks, but it's cheap. Thanks Ofcom.

Well I spoke too soon about my line being fixed IT IS NOT! I just had my snrm on upstream drop through the floor once again for no obvious reason and a re-sync which has dropped by upstream speed to 431kbps and the U1 & U2 bands with zero snrm, downstream has also dropped in speed to 49080kbps which is a drop of some 13000kbps.

I have just told TT that I need another visit from OR and this time they must take it seriously that there is an intermittent fault somewhere between the cabinet and my master socket and it needs fixing.

This intermittent fault would be hard to track down, it needs to happen when the engineers JDSU is in place and if not then no fault would show up as you noticed from the last OR visit all they did was  a DLM recalc and no fault found.

PS a fault like yours can take up to 6 OR visits to finally trace and fix it

[guest3]

6 months here... several engineers, cabinet repair (not the cards in the end) Finally synced at 77mb. Hope it lasts after all this work..

[broadstairs]

In fact this time it seems to have gotten worse as usually it was only U1 band which went to zero but this time U1 & U2, if U3 goes as well I wont get a connection at all!

Stuart

[NewtronStar]

Your DS SNRm has been gradually falling over 4 days since the DLM reset to me that's odd it has become a big thread has anyone suggested testing with a different modem surly the TT script would have ask this.

[Ronski]

The dBm power has dropped to a negative number, does that have any relevance?

[WWWombat]

Ugh.

The usual problem shows on attenuation - another increase at the same time as things go wrong; yes, @ronski, power goes funny too -sometimes negative, sometimes not.

Fingers crossed it stays faulty when the engineer is there.

[broadstairs]

In answer to the modem/router, yes when it happened before I tried the HG635 from TT but it happened using that as well as the ZyXEL, also happened using the master socket with all internal wiring disconnected (although there's not much of it now).

Looking at DSLStats and you can see it on MDWS at around 20:05 tonight the U2 band came back at around 20+db and U0 jumped to around 17.5db with U1 still zero, I have no idea what happened then but there was no re-sync - I was out at the time.

When I got back tonight I did a manual re-sync tonight and it has come back with normal speeds but the U/S snrm/band is a bit off in that U0 came back at nearly 9db with U1 & U2 both around 6.7, U0 has subsequently been dropping but not yet down to U1 or U2 level.

I could dig out my HG612 and try that in bridge mode to the ZyXEL but I'll leave that for now.

Stuart

[NewtronStar]

Looks like both the US & DS has developed what I call SNRm Jitter this is normal for longer lines as the modem tries to combat the effects of noise you won't see this happen where lines have very little noise on the circuit and the SNRm remains very steady over 24 hours

[broadstairs]

I understand about the jitter and that I probably have more noise recently however these wild swings in SNRM and drop to zero and far form normal, togther with the other indications I am fairly sure it is not my router but a problem with the line between here and the cabinet which is intermittent.

The dBm power has dropped to a negative number, does that have any relevance?

My understanding is that as the unit is dBm -- decibels relative to one milliwatt -- then the negative sign just indicates that the reported power is less than one milliwatt.

[broadstairs]

Heard back from TT this morning, guess what? They want to wait and see if it happens again before doing anything! Unbelievable, they cannot argue that my line is working within estimate when up drops to 430kbps. I have tried to insist but dont know if it will do any good.

Now you mention it, it has spooky parallels with what just happened with the EU referendum.
