    i have a problem with my main telephone contact box,my bt socket is smashed to bits so is hanging from the wall (baby walker) ,every time someone rings me my broadband disconnects...

    i purchased a new box (shown below) because i believe the problem to be from my adsl filter

    [​IMG]

    i have two wires from the exchange white and orange which connect on one side a and b but what about the adsl side ??? does anybody know what goes the otherside

    Firstly, you're not supposed to touch anything on the other side of your master socket. It's more than likely breaking the law. A and B are indeed on the side you're not supposed to touch but if you have simply replaced your smashed socket with another and connected it how it previously was, probably no harm done.

    I don't understand what you are asking. There is no "ADSL side" to a master socket. A filter fits into, or over the NTE5 (the BT master socket) and splits the signal into two connections; one which you use for voice/fax etc. (usually with a BT plug input) and another (usually with an RJ11 input) which is for ADSL. BT used to supply a nice filter that fits over the NTE5 for this purpose when ADSL was first released. You can purchase the NTE5 faceplate filter from somewhere such as http://www.clarity.it/xcart/home.php?cat=262.

    If you are connecting your ADSL modem/router to the RJ11 socket of a NTE5 master socket filter, and a phone to the BT socket of the filter, both devices should function properly. If problems still persist try replacing the filter and retest. If problems still persist you'll need a telephone engineer to troubleshoot because everything you can do will have been exhausted. The problem is beyond your home and therefore up to Open Reach to solve.

    If you are connecting your ADSL modem/router to extension wiring, which runs to other rooms throughout your home, although should be wired back to the NTE5 master socket, that is where you may have some issues and thus will need to troubleshoot each individual socket throughout the chain that may exist. Every secondary socket needs to be filtered *unless* those secondary sockets are *already* filted by a NTE5 master socket ADSL adapter (see the top of the link I posted above). Your extension wiring may also be of poor quality. That is why an ISP will always ask you to troubleshoot connectivity with them from the NTE5 master socket, as I explained in the previous paragraph. If your secondary socket(s) extension wiring is not filted by any NTE5 master socket ADSL adapter, then every secondary socket with a phone/fax/other device or ADSL modem/router connected to it will require a filter in between the socket and the equipment. Filters are known to fail so keep spares.

    To save having filters on every secondary socket in your house, the adapter at the top of http://www.clarity.it/xcart/home.php?cat=262 is ideal. Ideally you place your ADSL modem/router into the RJ11 socket on that and all your secondary extension sockets, throughout the house, are filtered automatically by being connected to the filtered IDC connector on the rear. You may also run a seperate ADSL extensios off the unfiltered IDC connector on the rear of this face plate.

    If you don't want to use this equipment, just buy a pack of normal plugin filters and put them in every master and secondary socket. Hopefully everything should then work, assuming your wiring is good.

    Many people are surprised at how significantly the quality of their Internet connection can improve when they connect their modem/router to the NTE5 master socket, before any extension wiring. Poor quality extension wiring can cause line noise and reduce the quality of the data connecction.

    Finally, if your secondary extension wiring is not connected to the NTE5 master socket, look on http://www.rob-r.co.uk/other/UKphonecatwiring.htm about how to wire to your side of the NTE5. 2, 3 and 5 are the connectors. Hopefully your extension wiring colours correspond as detailed.

    I trust I have sufficiently bored all that have read this far. :D

    we have a telephone engineer in our midst....

    yes the main bt socket was smashed from the wall and i bought a replacement (shown above)that has a twin entry,one for phone and one with a adsl connection via the rj11...

    i did try connecting the rj11 (adsl) to my broadband but it didn't work,i tried looking for wiring diagrams for the thing but couldn't find anything

    i will try the links you shown me and i appreciate your time for finding me the links

    Regards

    Mark

    The master socket you have purchased to replace the broken one may not really be a proper master socket. It might not be suitable for the job or it might be faulty, or poorly designed. I am not aware that BT have produced anything newer than the current NTE5 master socket (that's easy to Google, and "clarity" also sell them, I believe). If BT haven't, you may want to buy one of those and also buy the NTE5 master socket filter that screws onto the bottom half of the NTE5 master socket, as linked to via the "clarity" link I included. This would provide you with the BT and RJ11 ports.

    usually blue with white stripes goes on number 2, then white with blue stripes goes on number 5. orange with white is usually the bell wire and goes on number 3 but you only need to connect that for extensions.
    A master socket has a capacitor in it whereas extension boxes dont', or you can cut it out if using as an extension.
    That's assuming bt dont use 3rd rate contractors nowadays and use any old colours.
