The VDSL Faceplate should make a big difference to speeds and noise margins. Of-course noise margins are not necessarily indicators of shorter or longer lines, it is more to do with line stability. Generally the shorter the line the higher the noise margins as less noise is being accumulated.
There are some �untruths� in this paragraph.
A VDSL faceplate will only make a difference if there is extension wiring attached to the NTE.
�the shorter the line the higher the noise margin� Not true. The noise margin will attempt to achieve its preset target margin.... (there�s more to it than that, but essentially that�s the gist)
The VDSL Faceplate isolates the broadband from the telephone line and the orange ring wire. This should help eliminate any noise on the line. This is what the BT Openreach engineer told me when he came on the 3rd of February to install the Faceplate MK4.
Yeah, it is true that the noise margin will attempt to achieve the preset target margin. But it is also true that if there is line and the internet drops out, DLM will increase the noise margin to stabilize the connection and in the process this will lower the speed.
Generally speaking if you are able to achieve top speeds with a noise margin of 3-6 dB then you have a really clean line.
I only just moved to FTTC from ADSL on the 3rd of February. Before that I had ADSL at 12 Mbps with a noise margin of 9 dB because at 3 or 6 dB under ADSL my internet would drop out quite frequently like 2-5 times a day.
That was EO Line with a 1320 meters copper line to the exchange. But now with the FTTC cabinet that copper length has been slashed down to less than 300 meters.
This means that now under FTTC I have around a thousand meters less copper cable traveling from the cabinet to my property. Which is why now my line seems to be achieving stable sync with a 6.40 dB noise margin for the last 6 days or so. Previously this was impossible to achieve because that long 1000 meter copper line would collect a lot of noise on the line.
My understanding is if the router is syncing at 80000 Kbps and 19999 Kbps with a 6dB noise margin profile then DLM will not need to lower it down to 3dB as it is happily syncing at top speeds at 6dB.
The TP Link Archer is a good modem, it's got a decent broadcom chipset but the wireless on it isn't great. 5Ghz performance on it was really poor imo.
Being on a Huawei cab, I plugged in my old Huawei HG612 and bought a seperate cable router.
It's been rock solid. You're doing well getting full speed on that attenuation. It must be a nice clean line with little crosstalk.
17db my attenuation. 68/20mbps.
Yes, indeed there seems to be little crosstalk, perhaps because my cabinet went live in October 2019 and many people in my building are unaware that there is Fibre. I am probably the first and only person to have identified my cabinet going live on the 1st of October. So with less people being on FTTC and most of them being tenants they are probably not informed yet.
Crosstalk might affect me after 1-2 years, who knows. But as long as most people in my building living as tenants then hopefully they are less likely to subscribe to an FTTC package and therefore less likely to contribute to crosstalk!
