Phone Line query

[carlsbergy]

Hi, I have just refurbished a house which was vacant for a year before I started, I have run telephone sockets into most rooms via master socket as number 1 socket connecting wires 2 & 5 to every socket.

Q1 - Can I test the line coming into the property as there appears to be no sound? not sure if there would be after the property having a line disconnected for nearly 18 months now

Q2 - Connecting wires to 2 & 5 on every socket, is that correct as I read a post about looping to no.3 to make each socket ring ?

Thanks

You should also be connecting terminal 3 (and 4 if you want to do it text book style). Terminal 3 carries the ring current via the capacitor in the master socket.

The line is likely to be dead after that long not in service. You would need to get the line reconnected through BT or another provider, this will cost you usually, unless you sign up for a call package and minimum term. They may do it for free if the copper pair is still intact back to the exchange.

Thanks for reply, which colour cable to I connect to 3 ? Thanks

if you do get a phone service connection, then before bothering to connect terminal 3, try a phone in an extension. Most newish phones do not need that ring wire.
Also, it is often beneficial to broadband speed for the 3 circuit to be disconnected.

Thanks Tony

Not with the modern NTE5a Master sockets, or a socket fitted with a master filter or I plate.

Terminal 3 should always be connected initially. Some cordless phones and ones that plug into a power socket as well as the phone socket often do not require the ring wire (you can often tell by looking in the RJ11 on the base of the phone - there may be just two pins).

With ADSL, if you where to have speed issues, the number 3 can be removed from the MASTER socket only to correct the problem. The ADSL micro filters also provide ring current for a connected phone regardless of if terminal 3 is connected.

You should use the orange/white for the number 3. You should have used the blue/white and white/blue for the 2/5 terminals.

Most modern phones will have their own ring detection hardware within them, so it is unlikely that the bell wire will be needed.
If the bell wire is disconnected at the master, then it will be ineffective to any of the extensions, even if these are wired on terminal 3.
The following may be a useful guide.

The new openreach nte has a built in bell wire filter,also there is only 3 connections on the frontplate 2,5,and 3.If there is no dial tone you cannot run a line test on it.

Yes, but you only need to disconnect the ringer at the master to prevent speed issues (if they exist). No need to disconnect them from every socket. This way, the next tenent/home owner can easily re-connect if required, or when the NTE5a is ever replaces or an Iplate filter fitted, you do not then need to go around all the extensions re-connecting the ringer.

Even if many modern phones do have detection circuitry, you should still go for the worst case, especially as it sounds like this house is being renovated to sell. The person who moves in should have a fully functional set of extensions IMO. They can drop the ringer if their ADSL (if they even have it) has a poor sync speed.

Separating ADSL and telephones with a single filter plate at the NTE5 is the best option.

NTE5 compatible ADSL filtered faceplate with connections for filtered and unfiltered extensions. The Austin Taylor Faceplate Splitter is considered by some installers to give superior performance on installations which are a long way from the exchange or for some other reason have a marginal broadband signal.

There are other suppliers of ADSL filtering equipment.

The master NTE filters are great, but where developed prior to the newer IPlate filter, and before the introduction of the new NTE5a with the bell wire filter.

The Iplate filter and newer NTE5a are designed to allow you to leave the ringer connected on fringe area lines which cause issues with sync speeds.

The NTE5a master filter was used to filter all extensions, which means you can only connect your router to the NTE5a, unless you then wire a second set of extensions using RJ11 plugs to distribute the ADSL.

The iplate/bell wire filter improve the situation by removing the imbalance and impedance mismatch caused by the bellwire but you are still likely to end up with a less than ideal wiring topology and any reflections that come with it.

Another thing to remember is that with ADSL 2+ hardly anyone gets maximum sync speed so in a sense everyone is marginal and that makes improving the wiring at your end worthwhile if you care about getting the maximum possible speed.

Ideally you should either have the router at the master socket location or have a single ADSL extention going to where the router is with no branches and wired with good quality cable. Since you are likely to have other wiring to the router I don't see fixing it's location as a problem.

Topology good word not sure i know what it means but sounds good

The I Plate also has an RF filter which BT claim can improve line stability(same as a BT80B RF3), the openreach NTE5A's do not have this but do have the bell wire inductor which gives the best improvment. The faceplate filters (NTE2000) do just as good job as the ADSL signal is seperated away from the bell wire at source. If you can't plug the modem or router into the master socket then get the 6 way version of the faceplate like this which enables you to have an ADSL extension AND the benfit of a centralised ADSL faceplate.

The problems only start when you have an extension carrying the ADSL signal with the bell wire(unfiltered).
