ADSL & PBX

Hi all,

We have a Samsung phone system installed and a BT line on which ADSL is
enabled. I'd like to connect the BT line to the PBX, and know that I need to
basically connect in a microfilter like this:

BT Line ---> Microfilter Analogue Phone Port ---> Samsung PBX
|
|
|--------->Microfilter ADSL Port----> ADSL Modem

I've stripped back the wires on a the Microfilter and I've got a red and a
green wire, do I connect these to the two wires that provide the BT line
(which terminates in an 'NTTU'), if so, does it matter which way around?

I've then plugged a phone lead into the analogue phone port on the
Microfilter and stripped back the wires on this to find another pair of red
and green wires. So do I then plug these into my phone system's board?

Any help would be appreciated, many thanks!

I have to say that you one up on us as you can see wha you have we cant.

Is the BT line connected to a socket or the system, From what you say I
assume its not on the system, So is it on a socket.

If its on a socket, Plug in the filter, Get a lead with a BT end (DIY ext
kit etc) strip back the non plug end and connect the wires from 2 and 5 to
the PBX and plug your router into the RJ11 socket of the filter.

Several potential pitfalls here. First is that the NTTU terminals are
usually punchdown on the customer side and not designed for stranded
cord. I would personally connect a line jack (secondary or master, in
this case it doesn't matter) to the NTTU, then plug in the
microfilter, and use a short cord with crimped on connections to
connect to the existing fixed wiring.

If you think you can get a good connection to the stranded cable on
the krone blocks in the NTTU,and assuming the manufacturer has
followed the correct colour code, the green wire should go to the 'A'
wire terminal (where the white probably was) and the red wire to the
'B' wire terminal (where the coloured wire probably was).

Alternatively you may be able to find a hardwired microfilter with
screw or IDC terminals, (I know they're available in the US, not sure
of suppliers in the UK). This would be the ideal solution but may be
pricy if it's even available.

All you need to do is:-

BT Line ---> Microfilter analogue port --> PABX
l
l-----> ADSL Modem

The microfilter has no function as far as the ADSL signal is
concerned.

The PABX is usually polarity insensitive.
