I will do my best to explain my problem which can be complicated.
First I have TWO cables coming from my TERMINAL block on the OUTSIDE of my house.
One cable goes to the MASTER SOCKET on the ground floor and the second goes round the house
on the outside and then up to enter the upstairs study where it terminates at a STANDARD SOCKET.
Recently the MASTER socket was modified by Openreach (contractor) to acommodate installation of BT Infinity 2.
There is a CORDLESS phone attached to the MASTER SOCKET which works perfectly and is VERY QUIET.
Upstairs there is an CORDED phone attached to the STANDARD socket which is VERY,VERY noisy although working.
I have a MICROFILTER attached to the upstairs phone but the OPENREACH engineer removed the filter from the MASTER SOCKET.
I have tried the STANDARD socket without the filter but makes no difference to the noise.
Any comments or suggestions as to a solution to the noise problem most welcome
Solved! Go to Solution.
Your connection is star-wired which will impact your Infininty. The installer should have disconnected the upstairs socket and maybe removed the terminal block too.
I suggest you report a poor install and request an engineer who knows what he's doing to rectify the mistake.
that's star wired and needs to be fixed before infinity will be at best need upstairs extension wired to master socket
Thank you all for your most useful comments.
Could you explain what "Star Wired " means please as I am not well versed in telephony.
Also how could I use the "outside" wiring to upstairs to provide for a corded phone upstairs?
Is there some way of running an extension from the "Master socket" to upstairs using the existing outside wiring?
In the interim, try fitting a new filter in the upstairs socket.
Thanks again for your help however I have confession to make!
I have just been outside to check the wiring again and I have given some "duff" information.
What I found was as follows -
There is ONE wire coming from the BT Terminal block which disappears through the wall presumably to connect
to the master socket inside.
Coming OUT from the SAME hole in the wall is the wire which then proceeds round and up the wall
to the socket upstairs.
So it looks like the upstairs extension is in fact wired from the MASTER socket.
However I cannot determine if the connections for the downstairs phone/BT Hub and the upstairs Standard socket
are wired in parallel or series.
The fact remains though that the noise level on the upstairs socket is very bad compared with the downstairs socket which is quite quiet.
Could it be a problem with the STANDARD TERMINAL SOCKET upstairs or maybe even the HANDSET?
Does you master socket look like this?
If so, the upstairs socket should be connected to the back of the lower faceplate and if you remove the screws you should be able to see the connections.
If not, then that may be the problem.
Well yes the outer plate looks like your picture but in total it appears I have THREE plates all sandwiched together.
There are THREE plates as follows -
(1) The original master socket
(2) A plate in the middle of the "sandwich" - I think this was known as an iplate?
(3) The outer plate as fitted by the Openreach contractor.The BT hub is connected to one input and the base for
my cordless phone is connected to the other.
The Openreach contractor was only with me for about 10 mins max!!.
Once he fitted the outer plate he connected the hub,waited for it to boot and once the "blue" light indicated a connection he left.
He never checked the phone lines etc etc .Just left me to sort the rest for myself.
