Telephone extension sockets help

The_One_2

I am currently with VM for landline/tv/BB and have 1 master socket in the living room and 1 working extension socket in the main bedroom. However, we had an additional 2 extension sockets fitted by them in the other 2 bedrooms back in the days of dial-up, but they had to be disconnected from the box outside of the house, after some problem a few years back

In the next couple of weeks, i will be moving to an ADSL provider. I currently have an inactive BT socket in the living room, which will be getting re-activated

Question is:
Will i be able to get the engineer to hook up the disconnected VM extension sockets up to the BT connection, so i can use it as a BT extension socket in the other bedrooms...and thus have the router closer to the old and slow desktop PC's upstairs

Its possible that they would do this for you, however its an easy DIY job.
Your extensions are wired to the back of the removable faceplate on the BT master socket.


It is not a good idea to run a router from an extension as internal wiring can reduce your speed considerably.
You might want to consider buying a filtered faceplate which be neater that having dangling microfilters.

There is absolutely no problem running a router from an extension socket.

Just use a quality extension socket and do not connect the 'ring/bell' wire to the extension.

A large number of speed problems are caused by dodgy extension wiring, the link I posted covers this.

Only badly installed extensions. An extra few feet of properly installed extension wiring will have no adverse affect on ADSL speed.

I think a lot of the confusion about running routers on an extension socket stems from the failure to specify the type of extension.

The thing that needs to be avoided is having a ring wire which can feed back electrical interference onto the ADSL signal pair through the ring capacitor in the telephone master socket. Plug in extensions have a ring wire and using them for the router will reduce your speed. Even using them for a phone extension will screw up your speed unless you filter them at the master socket end.

If you have a filtered faceplate then there will be an unfiltered pair on the back of it which can be used to run an extension to the router which is fine if proper twisted pair phone extension cable or one pair of CAT5 ethernet cable is used. Connecting a plug in extension to the phone side of such a faceplate is fine too because the ring wire which is present in plug in extensions is isolated from the ADSL signal pair by the faceplate.

You can do the same on a normal BT faceplate so long as you leave all ringwires disconnected and filter extensions at the master socket end for phones.

The very latest BT master sockets contain a ring wire choke which pretty much solves the problem.
