Landline network - how to connect to master socket

I have the BT Openreach master socket in a remote corner of my house. Placing the base station for the digital phone there means it's a struggle to get good reception on handsets at the other end of the house (likely to due to build materials in the walls etc). The house does appear to have a network of conventional / old-style BT sockets but these don't appear to be connected to the master BTO socket.

I'd like to try to use this network - could I simply run a cable from the BTO master socket to the nearest old-style socket then plug a phone(s) into the network in otherrooms? (obviously being aware of total ringer equivalence limitations etc).

PS I do have an ethernet network too and it's working fine (touch wood) having been connected to the router and switch so wondered if I could do something similar with the landline phone side.

Thanks

@Pedr057 

Who provides your phone service, is it still BT?

Is your broadband an FTTC connection, or an FTTP connection?

Just run a cw1308 cable from the master socket to the extension. Only 2 wires are needed, connect to pins 2&5 on the removable faceplate of the master socket and 2&5 at the extension.

If its an FTTC connection, then a filtered faceplate at the master socket would be essential, as all those daisy chained extension sockets are going to have a bad effect on the broadband connection speed, causing open ended transmission lines.

Hi,

BT still provide both landline and broadband services.

The connection is FTTC (and I have a BT Hub-6 router).

The BT master socket has an integral filter so separate sockets for phone and router connections and no need for the old-style micro-filters.

Then you must ensure that you connect any extension wiring, to the block which is situated behind the front cover, as that is the filtered output. That will only let the phone part of your connection through, and not any broadband signal.

I am assuming you have the latest master socket, or is it an earlier one, with the broadband connection at the top, and the phone connection underneath?

Re: Landline network - how to connect to master socket

when you take the faceplate off master are there any wires connected to terminals 2&5?  if not are there loose wires and cable inside master which probably come from extension socket(s)

Re: Landline network - how to connect to master socket

The phone and broadband sockets are side-by-side and it says “Master Socket 5C” on top. 
I have a bookcase within a few inches of it so not readily accessible at the moment - not sure I’d feel comfortable with trying to take off the cover for a peek inside especially as I can’t see any screws.

The  old master socket From the previous owner/service is still there - presumably removing it would leave an unsightly hole.

There are no screws, the cover is simply clipped on.

Underneath you will see the white filtered terminal block. That is where the wiring to the other sockets must come from, otherwise you will affect your broadband connection and will get disconnections.

The frontplate is designed to be removable to gain access to your internal wiring, it just clips on with the 5C.
