Our house has had a history of chopping and changing telecom suppliers. At 
present we have Virgin Media domestic phone. I also have a BT line which was 
my home office line until I was made redundant. The BT line has an NTE5 ADSL 
splitter box in my office. This is connected using ordinary phone extension 
wire to where the original BT master socket was in the hall downstairs. Only 
the blue/white and white/blue wires are used, the other four not being 
unconnected at both ends. Nothing at all is connected to the original BT 
master socket faceplate.

The VM phone master socket is like the BT NTE5, but without the ADSL. It is 
placed right next to where the original BT master socket was. I have two 
extensions connected to the VM master socket.

I want to ditch VM , return to BT and use ADSL for my domestic broadband 
rather than VM cable. I would like to keep the BT NTE5 where it is now, in 
my office, but still be able to have the current domestic phones wired more 
or less they are now.

My understanding is that I can wire phone extensions into the BT  NTE5 using 
the IDC connectors labelled 2,3 and 5. Physically I could use three of the 4 
currently spare wires and use then to run back to an extension faceplate 
where the original BT socket was, and connect the extensions to that.

My questions are:

1. Would this be permissible, given that I would be changing the use of at 
least two of the wire colours?
2. Would it actually work, given that the extension wires would be in the 
same sheath at the two unfiltered incoming wires?

I suspect that the alternative would be to use an ordinary master socket in 
the hall, wire the office as an ordinary extension, and use microfilters 
everywhere. Is this correct?

Hope someone can advise on this,

Steve S

Yes, because your extension wiring would still be isolated from the incoming 
pair by removing the faceplate. BT only accept responsibility up the test 
socket behind the faceplate.

Yes it will work. It's probably frowned upon - but BT do it themselves 
sometimes. Mine (wired by BT) is *exactly* [1] like that.


[1] My original master socket was in the hall. Prior to BB, I had Home 
Highway installed. For that they laid a multi-pair cable from the hall to my 
office, using 2 of the pairs to take the extension wiring back down to the 
junction box which replaced the original master. When I upgraded from HH to 
BB, they put the new master in my office (where the HH box had been) and 
used the *same* (ex-HH) cable to bring the incoming pair up to the master, 
and the extension wiring back down to the hall.

Excellent! Thanks a lot, Roger.

I can understand not wanting to use their phone service with its 10p 
connection charge, but why not use VM for Internet? Despite what you may 
read on here sometimes they are still one of the best and most reliable 
ISPs.

The local UBR is greatly overloaded.  The upload speed (which is important 
to me) is very poor. I need a fixed IP, which they do not offer. Telewest 
used to be kind of OK, VM are not the kind of people I want to do business 
with.  The VM broadband is overpriced.  I could go on...

It may be simplest to make the "old" BT point the 
master, allowing direct connection of extensions and 
avoiding use of the same cable for internal and 
external wiring.  The ADSL faceplate could be 
installed on the old master box to terminate 2, 3 and 
5 on the 2 phone extensions (though I suppose BT could 
install a new one).

The extension cable to the ADSL modem outlet could 
then be wired to the AB terminals on the faceplate 
(the unfiltered line).

Not all SSFPs have a AB IDC.....

Just to close the loop on this. Yes, My phone is now with BT, number ported 
from VM. Wiring works fine.

BT did screw up initially. Connection was planned for May 28, but did not 
happen until Jun 5, as they had not informed VM. My complaint to BT that 
this meant an extra (wasted) £9-worth of line rental to VM was swiftly dealt 
with by BT with a £9 reduction in my first bill.
