Digital voice and voice reinjection to old phone sockets.

BiggerMike69 — Thu, 09 Mar 2023 15:47:07 GMT

Our phone was recently moved over to digital voice, rendering the old phone sockets unusable.
There must be a way of taking the phone output from the SH2 and reinjecting this output into the old socket wiring.

How is this done?

Simply by connecting the green phone socket at the rear of the hub to an existing phone socket with a double ended phone cord.

This is more complicated if you are still on copper (FTTC) broadband rather than full fibre (FTTP) as the master socket still needs to supply the broadband via the incoming copper pair.

If you currently have a master socket with a filtered faceplate (i.e 2 sockets, one for broadband and the other for phone) you have 2 options.

1. Simply unplug the removable faceplate and connect your hub DSL input to the revealed test socket via a filter (to convert the socket type) and then just connect the hub green port to the dangling frontplate. Obviously not an elegant solution if the master socket is visible.

2. Provide a new extension socket adjacent to the existing master and transfer the extension wiring from the faceplate to that and then use the double ended cord to connect to the hub green socket.

I found this YouTube video which shows a solution.

Exactly what I described except it is much simpler to use a double ended cord rather than cut the socket of an extension lead. £2.65 from Amazon.

However the explanation of why this may cause problems is in the video @6’45’’

Not really, with both of my scenarios the incoming line is isolated from the extension wiring. His video also is aimed at FTTP customers which is extremely simple to implement, just disconnect the incoming copper pair and connect hub to master with double ended cord.
