You plug the modem/router into the DSL port of one of the filters. Done as instructed (just described), that leaves all phone wiring in the property carrying the DSL signal and picking up interference. Typically, if the house was previously wired with a lot of extension sockets, fitting a whole house DSL filter at the demarc (master socket in the UK) gets you a significant speed increase! |

They are also pin-compatible in that the middle 4 wires of ethernet --- End quote --- They do, but the smaller plugs will bend the outer contacts of the RJ45 socket causing contact issues later on when inserting an RJ45 plug. Get a cheap RJ45 crimp tool and a few plugs. |

This allows you to use either cable for digital (ethernet) traffic or analogue (phone) signals. You can then use one as a phone line by simply having the appropriate patch cable. You can buy phone cables with RJ45 on one end and RJ12 on the other. Then, if you want to move to VOIP, you can change the usage of the second line without any rewiring or changing your existing ethernet setup on the other line. Also, with two ethernet lines, you have redundancy and/or expansion - which is never a bad thing. --- End quote --- Hint 1 - RJ45 to BT431 adaptors depend on the phone line being on pair 1 (i.e. the two centre pins) Hint 2 - you can usually insert an RJ11 lead directly into an RJ45 socket - again make sure the phone line is on pair 1, and you can sometimes get away without having to install an adaptor (my UK example: I have an ADSL filter where the phone line enters the house, a short RJ11 to RJ11 lead which plugs into a Cat6 ethernet extension back to the "server room". In the server room another RJ11-RJ11 cable is used between the patch panel and the DSL modem. This also has the advantage of dropping the unbalanced "ringer" wire along the extension cable, which gives a minor boost to the DSL line rate) |

Ok, slow down guys! ;D This is in the beginners section. The install is done, cat6 was run underground with the rest of the utilities so I can't add another cat6 unless I just run it down there externally. Likewise with a phone line. The electrician wasn't chosen by us, he came with the people who were installing the annexe. I just want a simple solution, or answer, to the problem. Many thanks. Mr Layman ;-) |

Do you need the phone line for a telephone or something else, like DSL for example? |
