Re: Drop in upstream sync


[re: youngsyp] [link to this post]
 
Now you can see the problem ... U2 is totally missing! It does seem a little odd that only upstream is affected, down looks reasonable

Re: Drop in upstream sync


[re: MHC] [link to this post]
 
Agreed, odd is the word I'd use too, even with my limited understanding. If anything, the downstream has a little more SNRM headroom than it would normally have. I'm sure it sits at around 6dB typically but now it's at around 7 - 7.1dB, increasing the attainable rate.
The upstream output power has taken a nose dive since I re-synced after the test last night. It's now at -7.2dBm.
I've just spoken to IDNet again, still not convinced by their customer service, and ran through much the same as I did last night. So hopefully an engineer visit will be arranged this time.

The power is the total power transmitted, so having a large number of bins with no data may suggest that they are being excluded for some reason. But why?

Can I suggest a power off and leave for an hour. Disconnect modem from the line, power it up and allow to stabilise before reconnecting. See if that changes it.

I'll give it a try tonight if I get the opportunity.

A battery fault shouldn’t need the engineer to access your property, unless you have a buried frontage tee joint .... even then it would only be to track and mark for a dig.

Well I got yet another call from IDNet today stating they need me to do something else to 'convince' OR to come out and investigate. This is all despite me stating twice now that I'd happily cover any costs incurred, should it be on my side of the DL.

So I now have to plug a phone in and check the line.

IDNet continue to go down in my estimations and I'll be jumping back to Uno as soon as I possibly can.

A screen shot showing U2 being totally empty should be enough to persuade IDNet and BT/OR that there is a problem.

IDNet have a screen grab of it now so we'll see what they say. Not much I suspect!

I'll try your suggestion of disconnecting for an hour tonight too as I'll have to unplug everything again for the phone test anyway.

Can you also get a text/screen grab from DSL Stats of the pbParams page especially the section which says:

Bearer: 0, Upstream rate = 19999 Kbps, Downstream rate = 80000 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps
Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3970)
Medley Phase (Final) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3970)



Do one BEFORE you disconnect and one once you have reconnected.

If it tests battery, then they should just raise it as an issue with Openreach ... why are they dragging their heels ?

Do you get your voice services from them too ?
