That device is the original centralised filter, designed for use with ADSL(2+) services.

The Mk 1 SSFP for VDSL2 services is as Colin_London has shown in the image, to which he has provided a link.

Ahhhh .I've got it now.

Purrfect!

Spot the difference

MK1, MK2 & MK3 Openreach VDSL Faceplaces

What I have is different from any of those.
It is printed (like Mk2 and Mk3) rather than embossed (like Mk1), but has no Mk number at all.
Possible discovery of a Mk1a?

The question is, would I get any benefit from upgrading to a newer one?

A Mk 1 SSFP (for VDSL2 services) is not marked "Mk 1" -- it is, essentially, anonymous. It is called "Mk 1" reterospectively.

Colin_London has provided an image of the three variations of the VDSL2 SSFPs. Any subtle differences noticed (printed rather than embossed, etc) is due to different manufacturers.

Now take them all apart to show the components and layout, then draw the circuits with component values. From the original to Mk2 there could be enhancements to use 17MHz profiles and maybe the Mk3 has been further enhanced to either improve performance at the top end or maybe extend it to 30 MHz.

Likewise, in description and question.

Mine was installed by Openreach, not a subcontractor, in February 2011. I think that predates the Mk 2.

BT Engineer replaced a circa 1967 faceplate and installed at MK2 at my place 2 weeks ago as part of a fault finding exercise prior to fixing the problem I had. I must say it's had an impressive effect - raising my downstream speed from 11Mbps-ish to the new sync of 14211kbps. Also, the Attenuation went from around 36 to the new current value of 34, with the SNR now dropped to 4.7.

Well I suffer from REIN so fingers crossed it reduces my disconnects.

Just changed my MK2 to the MK3. There has been next to no change to my maximum upload data rate figure - the one I am most concerned about as I believe data rate falling below target data rate (now 19567kbps) when noise occurs is the reason behind my disconnects.

Maximum download speed has in fact fallen by 1.3Mbps to 63183kbps , but this is of little consequence as DLM has capped at 59995kbps.

What has changed is that my noise margin appears to have marginally increased by 0.5dB on both up & download, and line attenuation fallen by 0.2dB.

The proof is in the pudding though I guess, and we'll see how the connection stability pans out. But on the above basis I am not expecting a huge improvement.
