Yep, if you want to get anal about it, one with only the two middle contacts terminated in each connector is microscopically ’better’ than with all four connected … this being observed from ADSL days, so less important with so much more bandwidth squirted down it.

I know Sky now send out PSTN jack to RJ11 cables with their routers for SOGEA provides, (an RJ11 to RJ11 lead also) ….so I dare say they can be easily picked up .

Its the same cable dialup modems used so should be pretty easy to find.

Or a BT Plug to RJ11 Female Socket Converter if one wished to use an existing good quality RJ11 cable, although in the OP's case that might not be a desirable connection at the NTE5 end.

One of these will do …. https://www.ebay.co.uk/itm/371451457072?mkcid=16&mke...

Yeah, but you get the gist. 😁

Just out of interest: would a fault at the exchange causing an xDSL drop when the phone rings be initially eliminated with a switch from PSTN to VoIP or SOGEA, assuming the E-Side pairs are still connected? Is there still a soft dial tone (or something) on the analogue line?

Certainly the phone ringing issue was cured for me when I moved from WBC to SMPF yet retained WLR voice.

That’s a tricky one …. was this VDSL ?

If it was VDSL, it really ought not to be affected by an exchange fault, the splitter in the DSLAM stopping anything E side affecting after the DSLAM.

There used to be, commonly, soft dial tone on lines after conversion to SOGEA … but then the number couldn’t be rung, it being out of service, so an exchange equipment cause looks unlikely. For quite some time now, E sides are now disconnected during a cabinet visit for provision or repair.

However, if this was an ADSL service before and after the switch … then the cause was most likely faulty BTw ADSL ties.

In my case it was an ADSL fault that a SFI couldn't fix on the day - but since there is potentially a soft dial tone with SOGEA I was wondering if a noise event occurred, due to an exchange fault, this could cause a VDSL line to drop.

Thanks for the reply and the detailed explanation.

Phone calls work that way. Your connection will be naturally more reliable and maybe gain a few megs more as the voice dial tone removal in Digital Voice eliminates any possible noise interference's caused by the phone line. If you've ever had connection drop outs when picking up the phone when it was ringing on Analog Voice you'll no longer suffer from this problem under Digital Voice.

No you won't gain a few megs, Theres nothing extra gained from the analog phone portion being removed. The only way you'd gain anything is if the frequencies were re-assigned for xDSL!. And that aint gonna happen. You can still have drop outs on DV, due to bandwidth issues.

I'm not saying that Analog Voice removal will help gain more speed. What I'm saying is that the migration to Digital Voice means that if you've ever had problems with connection dropping out when picking up your phone that problem is bound to go away with DV!

If you look at this article https://telecomgreen.co.uk/home-phone-repair/bt-open...
There is already evidence that removing the orange ring wire helps improve connection stability. There's less noise on the line.

Why remove the ring wire?

Unfortunately, the ring wire can also act as an antenna, picking up interference from other electrical equipment in and around the house.

It is often found that disconnecting the ring wire improves the stability of a connection, sometimes considerably, especially on "star" wired telephone systems.

If the connection drops out due to noise margin issues DLM kicks in and lowers your sync speeds! But if your connection is stable at higher sync speeds then DLM does not reduce your speeds.

Now, ever since migrating to FTTC from ADSL EO Line in October 2019 my connection improved immediately and my random drop outs stopped.
My first FTTC package was with TalkTalk + Analog in February 2020. Picking up the phone would sometimes cause drop outs, not always but sometimes. NTE5C Master Socket improved my SNR as I was making comparisons with it and without it.

2 years later I switched to BT FTTC+DV. I noticed how I'm no longer dropping out as my sole problem was related to the analog phone!

I'm still syncing at Downstream sync speed: 79.999 Mbps Upstream sync speed: 19.999 Mbps
No drop outs and stable sync. But with analog when picking up the phone while it was ringing will result in my internet dropping out and my connection sync speeds reducing! I then had to wait for several days before my sync speed returned back to normal. But the phone was the culprit for this.

This is a similar experience to what you'd get with Dial-Up. If you are old enough and ever remembered using Dial-Up you'll know that you can't use Dial-Up internet and at the same time use the phone. Your connection will totally cease to function until you hang up the phone. This is not line fault related, this is something everyone experienced.

Now you could argue in my case there must have been a line fault somewhere. But with FTTC analog phone pick ups were my only problems with drop outs. I don't have any other drop outs like with ADSL. If I had, I would've been complaining here on these forums for support.

But my connection is super stable last 2 years, so much that I didn't rush to switch to Community Fibre yet! I'm pretty happy with my BT FTTC+Digital Voice service. If I switch to FTTP that will be mostly for higher speeds.

I'm not saying that Analog Voice removal will help gain more speed

Yeah, you did say that.

Your connection will be naturally more reliable and maybe gain a few megs more as the voice dial tone removal in Digital Voice

Disconnection of the bell wire on internal wiring has nothing to do with what you are claiming.

Your line has been more stable because the greatly increased bandwidth it now has comes a shorter distance than your old ADSL service.
