ADSL Wall Fascia Wiring?

[slipd]

Hey guys,

My mate has just given me 5 of these face plates with both a phone input and a direct ADSL connection – with microfilter built-in; no, more ‘dangly’ for me then




Thing is, I don’t know how to wire the A & B connections at the top (Circled)? You obviously have to bridge the two connections (Phone and ADSL) but how

What wires go where?

Can anyone help me out? Apparently they also improve your stats… Very slightly?

Cheers

SW.

If you have a single phone line then you only need 1.

Your incoming phone line at the master socket will have 2 wires. Connect one to A and the other to B.

The other connector, a short IDC strip, is the filtered line (2 & 5) and ring (3) for your phone extensions.

Easy if your ADSL modem plugs into your master socket, a bit more tricky if it doesn't.

Dunno about giving better stats, but being BT the filter is regarded as being a higher quality than the cheap filters people usually buy.

Thanks for the reply mate

I'm going to be using these mostly on extension lines if possible? I'm probably going to leave the master socket alone?

When I try to install these on a 4 wire line - how to I connect A & B? What wires is it I use

Cheers,

SW.

When you say "mostly" on extension lines remember than any extension with a phone has to have a filter.

If you're going to use these, what you're effectively doing is having multiple masters. I don't know what the full effect of doing this will have on the line, but I wouldn't do this myself

Usually the line from BT uses 2 wires to the master socket on A and B and 4 wires are used to the extensions. Usual colours for the extension connections are blue on 2 and blue/white on 5 for the line, orange on 3 for ring and orange/white on 4 which is generally not used.

Since they're masters with their own ring circuitry, you shouldn't connect ring between themselves, so all you need to do is find the pair used for 2 and 5 on the main master and connect this through on A and B of each socket.

That usually isn't the case when your extensions hang off the NTE5 with ADSL filter built in as the filter is before the output for the extensions, ie, the extensions are already filtered.

These faceplates ideally replace the master socket. As per Tui use just one, as your master socket, sell the others, they are not cheap whilst extension cords and sockets are!

If your adsl modem is on an extension shared with phones you should feed another of these face plates with unfiltered signal. Feed its AB with a pair of wires of your choice from the AB of the master (no ring wire needed).

If for some reason you want to leave the master as it is and just use these elsewere in the house the A-B wiring in the master usually maps to its idc terminals as follows

2 B Blue / White Line signal B
3 G Orange / White Ring Signal
4 - White /Orange Not Used
5 A White / Blue Line signal A

So you could try

your old master sockets terminal 2 blue/white to B and
terminal 5 white/blue to A

no other wires should be needed for filtered sockets, 2 master sockets usually work but its not ideal.

its not clear from the photos if you will have to disturb AB wiring BT reserve for there use only!

You can buy filtered extension faceplates.

Your 4 conneections at the bottom are 1 pair for DSL the other pair for phone. the 2 at the top are the single pair the original signal comes down (like a normal unfiltered line). Or at least one would assume. Not everything is completely standardised and it's always best to read up in the instructions.
Normally It's 1 pair in, 2 pairs out to the front part. Ifall else fails, trial and error.
