chlorophyll Posted March 14, 2010 Share Posted March 14, 2010 Ok so after trawling the web about a problem with my router, I came across this page (See end of post)What it shows you, is how to reduce the noice on your landline thus increasing the bandwidth of the line and in turn increasing your broadband speed.How it works is this... You turn on your router, and the router checks the noise and other things on the line, and sets a stable speed between you and the exchange, the less noise you have on your line, the more bandwidth it can allocate you for ADSL / ADSL2+ / DSLSo this guide shows you how to remove the Bell Wire from your Phone socket which is not used now, as it used to carry the 50v signal to ring the Bell on the old style phone, new phones dont use it and it just collects interference.I have done this because I was getting dropped to 4482kbps connection, and now my broadband speed has jumped to a stable 5851kbps connection !!4 The Science.At the Home Hub Foruma contributor codenamed Bramshot told me his story of the BT engineer who removed his bellwire and the subsequent hike in speed. More web research I did using Google and Yahoo also came up with the theory that the "bell-wire" is the cause.The Bell Wire is the third wire on terminal 3 (usually orange/white) used in the standard BT extension wiring that was introduced in the early 1980's when DIY extensions became legal, and BT relaxed their monopoly on supply of phones.From under the road or along a telegraph pole, your house is served by just TWO wires. This third "bell-wire" is generated by the BT master socket and enables actual bells on old type phones to ring using the 50 volt AC ringer signal. Modern phones have electronic ringers which do not need the bell wire. Its other function is to stop other bells tinkling when rotary dials are used, and it was always known as the "anti-tinkle wire" in the 1980's when we all experimanted with DIY extensions.On standard domestic phone with broadband and individual ADSL filters you don't need any wires apart from the two main conductors on terminals 2 and 5, usually blue/white and white/blue. This is because ADSL filtersisolate the phones from the bellwire and recreate the function in the filter. This makes the bellwire totally redundantin a broadband enabled domestic phone system.Leaving the bell wire in place creates a huge long antenna which picks up radio frequency (RF) interference all over the house. The two conductors that carry the voice and DSL signals are a "randomly twisted pair" which carry current in opposite directions (from master socket to extension socket and back again) so the RF interference cancels itself out. The unpaired bell-wire cannot cancel out the RF.There is also another redundant (white/orange; terminal 4) wire which has never been used by BT on simple domestic wiring. Best to disconnect this too to avoid confusion.Source and instructions and Pictureshttp://www.jarviser....renutshell.html Link to comment Share on other sites More sharing options...
