Right, so I left it a couple of nights before proceeding because, as if by magic, my connection suddenly sorted itself out on the evening of the day I started posting in this thread. My connection remained absolutely perfect all through the night, and the following day, and the following night.
Today it behaved just fine until left for a few hours this evening; when I returned, it was the slowest yet; check the following (wired) tests:
I had to restart the router before I was even able to run a successful test, although this time restarting it has barely improved performance (whereas usually it tends to work a little better immediately after).
Therefore my most recent ADSL stats aren't over a particularly lengthy period, but they are as follows:
ADSL Line Status
0 days, 01:54:55
G.992.5 Annex A
Noise margin (Down/Up):
4.8 dB / 6.8 dB
Line attenuation (Down/Up):
14.5 dB / 7.5 dB
Output power (Down/Up):
19.9 dBm / 10.1 dBm
FEC Events (Down/Up):
0 / 0
CRC Events (Down/Up):
355457 / 32
Loss of Framing (Local/Remote):
0 / 0
Loss of Signal (Local/Remote):
0 / 0
Loss of Power (Local/Remote):
0 / 0
HEC Events (Down/Up):
4218732 / 7
Error Seconds (Local/Remote):
6831 / 0
I don't know what HEC events are, but over four million in nearly two hours seems like rather a lot.
Regarding my 'star wiring' setup, I did some investigation in the BT junction box in my porch. It turns out that the secondary wire (to a redundant socket upstairs) isn't actually connected any more; instead, the incoming wire from the exchange is attached to the same two clips connecting the wires to my current NTE5, as below;
I asked a DIY forum for advice and included these photos. They have also all advised I rewire the two BT wires from the faceplate of my current NTE5 to the backplate, as it should be, and I will then have a conventional wiring setup as BT require. They also stated that regarding the above, I should plug the incoming wires from the exchange into the A and B screws but as it seems fragile and old, I'm better off ripping the box out and crimping the exchange's wires with the BT wires to the socket using insulated crimps.
Please could someone have a look at this evening's stats and see if they can offer any advice? I cancelled BT's engineer appointment for today on the basis that my connection seemed to have sorted itself, but it's now back to square one apparently 😞
ALL of the wiring upto your master socket is the property of BT/Openreach. However, you might like to have a look at.......
BT 80B RF3 Junction Box (3 way IDC to 3 way screw).
The cables from the exchange (white and orange) go intothe "A" and "B" screw connectors (top right in picture).
The cable to the master socket (blue/white and white/blue) go into the "A" and "B" IDC connectors (bottom left in picture).
The IDC connectors require a special "IDC insertion tool", and a decent one is available ......
IDC Tool , Insertion tool to allow termination to IDC blocks
A new NTE5 master socket is .......
BT Openreach™ (Embossed Version) NTE5 Master Socket
And a new ADSL faceplate is available .....
BT NTE-2000 ADSL Faceplate for NTE5 Socket
This would bring your connection upto current standards. ALL hard wired extentions would then be wired off the back of the faceplate. Should you need to connect to the test socket, then this just requires the simple removal of the faceplate. This gives you a direct connection to the exchange.
Hope this helps.......
I would definitely NOT crimp the incoming cable to the cable going to the master socket.
Thanks very much for your input, that's all really appreciated! 🙂
It seems like you might have pasted in some HTML links that didn't display properly in the thread, is this the case or am I putting two and two together to make five?
Also. The existing BT junction box is VERY old and frail and the IDC connectors in there look like they're about to crumble. I am more than a little wary about yanking the existing wires out of them and trying to insert them again - is there any way I can rid myself of this goddamn box completely so I don't have to worry about it any more? You say IDC crimps are not a good idea?
BT have specifically advised me that if I want to get my own engineer to terminate the cable from the street on a new NTE5 then I'm more than allowed to and more to the point well advised to, as it will be a lot cheaper than getting their engineer to do it.......
Ok, thank you for the heads up.
You are right.....!......... It appears my message has been edited. If this is because it went against the rules of this forum, then I humbly apologise......I shall see if I can find photos of said items somewhere.........
