3 phone points

They definitely will ring on just 2 & 5

How exactly will that work then? Power is applied to the line when a call is incoming and the master socket creates the ringing pattern on terminal 3.

If you don't have it, you don't have a ringing wire.

I don't claim to know the theory.

But my phone rings........

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The main reason for this, involved ‘pulse-dialling’, which has now been replaced by ‘tone-dialling.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.

Hopefully this will explain the master

Maybe the phones in Cyprus are now incorporating the ring components, perhaps the telephone system all changed since building the house, i really don't know!! All i know, the technician chopped the components out of the master!! To be honest i didn't take that much interest at the time, but the phones all work including the ringing, and haven't had any broadband connection problems since!! lol!!

there are lot of people not receiving phone calls if it doesn't work on just 2 & 5....


i did call them to see but non of them answered perator:

Only 2 & 5 needed these days connecting terminal 3 can be a cause interference which reduces broadband speed

If you want to connect terminal 3 and your broadband speed reduces then BT suggest fitting an I-Plate which disconnects the ring wire

I have a quick of topic sort of ish question, ive done these before with 3 phone sockets.. What is the maximum Master to Slaves you can have on one? Is it unlimited or can you actually have like Master - > slave 1 > 2 > 3 > 4 > 5 > 6... 7 Telephone points ;P !

There is no limit on the number of line jacks you can install your limit is the total number of REN (ringing equivalence number) connected to the line the maximum is 4 before problems occur. All telephone equipment has a REN value most phones are 0.5 but some can have a REN of 1

Got a job to do for a customer next week where I'm expecting problems as sky are insisting all their boxes are connected to a telephone line the customer has 7 boxes plus the phones
