The central splitter is installed as follows:
The POTS/ADSL line is connected to the splitter input.

One output, containing POTS signals only, is connected to the
"
existing in house POTS network.
The other output, containing POTS and ADSL, is either
"
connected to:
A dedicated spare wire pair in the existing telephone
D
cable.
A newly installed cable if no spare wire pair is available
D
(Ensure that the installed cables are of sufficient quality).
Depending upon the existing electrical wiring and sockets, ADSL
should now be present on all of your wall sockets. In case of a
new dedicated cable, ADSL service is only present on those wall
sockets attached to this cable.
Inside the Speed Touch Home, dedicated filters remove the POTS
signals, consequently only the ADSL remains to be processed by
the modem.
The central splitter can be either external or internal to your home.
If external, it is installed by the ADSL provider/operator in what is
often referred to as Network Interface Device (NID).
The NID is mostly an outdoor enclosure terminating and securing
the public telephone cable. For the telephone operator it is the
demarcation point between the public and private section of your
line.
