No worrys BC I fully understand I hate to admit it but opening it up and testing the circuitry with soldering iron at the ready would have been a joy 15 years ago but not these days don't get me wrong I will try my best to get a broken thing working again but my patience is very low

[burakkucat]

A further thought . . .

Have you tested with the SSFP removed and connecting the VMG8924 (& a telephone) via a "rat's tail" micro-filter directly to the NTE5C? I am not impressed with the construction quality of the NTE5C and its associated "clip-on" face-plates.

[NewtronStar]

Think I was a bit over enthusiastic with change of modem it's now showing a drop of SNRm on the Billion 8800NL when phone is in use but not as much 0.5dB compared to 2.0dB ZyXEL.

I am not impressed with the construction quality of the NTE5C and its associated "clip-on" face-plates.

And neither am I BC, look I'm not one of those people who just hate new designs or the like yet a good hard wobble of the 5C unit will throw up some errors in the stats especially where the phone jack plugs in.

Ah, so perhaps the problem does originate elsewhere.

. . . a good hard wobble of the 5C unit will throw up some errors in the stats especially where the phone jack plugs in.

Hmm, that is definitely not good. I would be very tempted to revert back to a NTE5/A plus a Mk 3 SSFP.

[NewtronStar]

I'll be honest with you my VDSL2 circuit has not been able to hold onto its sync at best 1 day 3 hours and worse case 4 re-syncs per day in the last 7 weeks and reason why I changed the modem from billion to zyxel to see if it made any difference unfortunately it had the opposite effect for 3 weeks.

[Chrysalis]

You have any long term data plots so we can analyse?

[NewtronStar]

No Chrysalis the RPi was decommissioned last year as the circuit was very steady with 130 days under its hood, work is being done in the village to create 40 new homes, the only thing I can put a finger guess is when it rains or prolonged dampness and we know how hard that is find and fix.

[NewtronStar]

Having taken some of BC's advice I examined the Master socket 5C over the weekend as it definitely was the culprit as I was able to recreate issues by slamming the door which next to Master Socket stud wall and pulling on the phone cord and so on, Took the MS 5C apart outer plate and unscrewing inner part then rechecking the cam connections then reassembling it back in as tight as it would go.

So now getting close to 2 days uptime and better looking errors and no SNRm drop at all when using the phone.

I'm glad to know that you have finally established the guilty party.

NTE5C    (My early 1980s NTE5/A is still serving me well.)

[NewtronStar]

You don't have a link close by for the MK3 do you ? the last OR engineer stole the one a bought from mr telephone

I've only got a few eBay links --

Hopefully one of those will fulfil your need. 

[NewtronStar]

Cheers BC but now when I think about it would need a NTE5/A and a  MK3 SSFP and also the front plate which has phone and Internet sockets so that is 3 parts in total if my memory serves me right

[burakkucat]

So you will require something like one of the following --

https://www.ebay.co.uk/itm/Master-socket-NTE5A-Instructions-Genuinely-BT/123603872962
https://www.ebay.co.uk/itm/NTE5a-Master-Socket-IDC-With-Backbox-BT-Virgin/233116642198

[NewtronStar]

Er Em well I was thinking if it was possible to purchase all three as one unit but looks impossible so the  Openreach Installed NTE5c and MK4 SSFP will have to stay in situ until I can find a better Openreach Backstop than what is currently available and leave with no deal 

[burakkucat]

I'm sure that I've recently seen the full "three piece set" but nothing was obvious in my quick checks, earlier this evening.

Edited to add: Found it . . .

https://www.ebay.co.uk/itm/bt-openreach-mk3-vdsl-filter-nte5a-master-socket-bK-box-idc-tool/323722037126

. . . but look at the price! 

Another one, at a slightly better price --
