Happy New to Everyone.
Firstly, thank you to everyone who contributed to my previous thread.
I did resolve the problem relating to high levels of hiss when I changed my router from the DG834GT to the TP Link W9970. It turns out that I had a microfilter plugged into a telephone socket which did not have a phone connected to it. The microfilter was hidden behind a piece of furniture. When I removed that microfilter, the hissing stopped and the phone line returned to how it was. I did replace that microfilter with a different one and no hiss on the telephone line. I have now placed a DECT wireless phone on that socket and so far no issues.
So looks like it was a microfilter that was the issue with my new TP Link W9970 router.
I have had the TP Link W9970 connected now for a number of days and all seems ok for now. No reboots or loss of sync so far.
I have intensively investigated my wiring and although it is still my intention to get a telephone engineer in to have a look at it, I wanted to get your opinions first.
I am currently on ADSL2+ C&W LLU with Xilo and wanted to upgrade my BB connection to VDSL (40 dn, 10up). My ISP, Xilo (Uno), are having a special on the TTB Fibre LLU this month with no inward migration and they confirmed to me that there is room on my exchange (so far).
I have read that VDSL is much more susceptible to noise on lines and ‘irregular’ wiring and as such I wanted to make sure that I attended to matter now rather than after my migration to VDSL.
Let me give you all the details.I live in a two bedroom maisonette in a Victorian conversion. There are other residents in the building and some commercial units at ground floor level.
The telephone lines come in underground to a utility room in the basement of the building.My telephone line seems to run up the skirting board of the communal parts and enters my flat
The layout of my flat is as per below.I have 3 telephone sockets in my flat as shown. I have taken pictures of each socket and the wiring insideSocket 1This is a twin socket. There is nothing plugged into either slot. The right socket has my phone line. The left socket although wired has no dial tone at all. Perhaps it was used previously as another line for a modem.
Socket 2Microfilter and DECT wireless phone
Socket 3Microfilter with BB and hardwired telephone. I intend to keep using this socket with my VDSL connection.
I have trawled all over my flat (including under my staircase) and cannot find anything that resembles a junction box or block. Also, there are no wires of any kind that are affixed to the outside of the building and enter my property.
As an aside when I first bought this flat some 4 years ago I did remove the ring wires from all the sockets and it led to an increase in the SNRM on my downstream from 8.3db to 10.9db as per below.
The current stats from my TP Link W9970 are as follows and are pretty much the same as those from my old router the DG834GT. I did have interleaving removed a while back so the photos above of the DG834GT stats are pre that.
My old DG834GT was very stable. Some reboots but nothing that would cause concern. Seems the W9970 is on par here also.
With the TP W9970, the telephone line for voice calls is very clear. The QLT on all sockets is very good. There is possibly a very but very low hissing in the background (mute was on). Pings are very good, 12ms to the bbc.co.uk. This is important to me as I use a Linkys ATA for VOIP calls.
My old DG834GT was the same as in para above, re QLT and pings.
1. I could not locate any drop wire / BT line in any of the sockets.
2. It looks like I may have star / spur wiring in my flat. Socket 1 (which has two plugs) has 2 capacitors in it and appears to be a master socket but there is no drop line / BT line attached to that socket. Searching on the net, I think that this socket looks to be a LJU4/1A (has capacitors, surge protector, resistor, IDC). It is manufactured by MK.
2. Socket 2 appears to be daisy chained to socket 3 in my living room which is where my BB resides. I did not confirm this by removing the 2 wires leading to the living room socket at this stage. But the colours of the wires seem to indicate that.
If it is the case that I have star wiring then the internal wiring to my flat should look like this.Clearly, if I cannot find any type of junction box or block inside my flat (it could be under the floorboards, then it is going to make changes to the existing set up and wiring particularly difficult as I have wooden floors throughout.
3. Is it possible that my telephone line is connected straight to the junction box in the basement so that a telephone line runs from socket 1 to it and a separate cable feeding socket 2 (and 3) also runs to that same connection in the basement and that there is no block which spurs the wiring inside my flat, if indeed I have star wiring. If you see what I mean.
I would like to have your opinions as to my wiring, is it star or could it be point 3 above, or other?
Also what changes can I make to improve my set up so that I can at least have a viewpoint when the engineer arrives.
As a footnote, I have found my BT cabinet and there is a Huawei VDSL cabinet adjacent to it. The BB FTTC checker says
Sorry long post. Ps can resize the images if too small let me know.
Any info much appreciated
Cheers
