What’s all this about the ring wire removal then?
Many users on ADSL-Guide have found disconnecting the ring-wire from terminal 3 has improved line stats, sometimes in huge amounts. A forum member sent me this information. (I deleted your email, so email me and I will add your name to the Bibliography)
Many years ago the UK telephone system adopted a different policy to that in the rest of the world. Here in the UK a choice was made to move a ring component, which enables the telephone to ring, out of the telephone and into the master socket.
The main reason for this, involved ‘pulse-dialling’, which has now been replaced by ‘tone-dialling. It was a good idea at the time because it made it possible to stop the ‘tinkling’ that occurred on other extensions when a phone was dialling.
However, there was a downside: To get the ring signal into the telephone we now have to run a third wire from the socket to the phone. Also, since we only need one ring capacitor on our line, and it is located at the 'master' socket, we have to take three wires to all our extensions, rather than the two wires which come to the house.
On most modern wiring you will find the original phone signal connected on the 'blue-white' pair of wires (Terminals 2 and 5) and the extra 'ring' signal connected on an orange wire (Terminal 3), though these colour codes are not always followed.
Now, since ADSL filters only filter the main telephone pair, they must re-generate the ring signal themselves. All of this is of only passing interest but it does mean that you only need to feed an ADSL filter with two wires. The ring signal for the third terminal on the attached phone is generated internally. Since most telephone extension wiring consists of two pairs, you may find this information particularly useful if you need to use a particular run of pre-installed cable for both a filtered and unfiltered signal (However Cat5e/Cat6 has that extra pair remember?). It is up to you if you wish to remove the ring wire, and the reasons for doing so are listed later on in a section that Phil, better known as Yarwell from ADSL-guide as written.
If the incoming ADSL signal is weak, or mixing with a lot of interference, it is possible that the layout of the extension wiring within your premises can degrade the signal even further.
If you suspect that this maybe a problem, then you will need to do all you can to optimise the layout of your wiring.
The basic principle is to ensure that there is only one path for the ADSL signal - from your master socket to your modem. If it is running off an extension then there should be no blind alleys caused by t-junctions or branches on the way. All of these blind alleys should be closed off with a filter so that the ADSL signal cannot pass down them.
