Telephone Interface Module
Art. 380N/UK Telephone Interface Module - Installation Instructions
Connections to a Telephone Line
INTRODUCTION
Each incoming telephone line into your property must be fitted with a 6 pin primary BT socket and installed by the
PTO
(Public
Telecommunication Operator) for UK based customers or the equivalent telecommunications operater for your country for all overseas
customers.
IMPORTANT NOTE: It is illegal to tamper in any way with this primary socket and you can’t install it yourself. Additional connections
to the primary socket must be carried out using a BT style plug. You cannot connect directly to the terminals inside.
The
Art.380N/UK
telephone interface unit is supplied with a BT style plug. For more information, see relevant paper work supplied
with extension sockets.
When connecting additional equipment to a telephone line it is good practise to first check the equipment already installed by
previous engineers. This includes any additional secondary sockets, digital set top box such as Sky Digital, faxes, modems, Broadband
and REDCARE alarm monitoring etc. The following precautions should be observed when connecting to any of the named above.
SECONDARY SOCKETS
If secondary sockets are installed, open each one and check it is a secondary socket and not another master (a secondary socket will
not contain any components whereas a master socket will have a capacitor, resistor and suppressor fitted). Only one master socket
should be connected after the
Art.380N/UK
. If there are more than one fitted they must be replaced with secondary (slave) sockets.
SKY DIGITAL, FAXES, REDCARE ALARM MONITORING AND MODEMS
Sky digital, fax machines, Redcare or any other
form of telephone line based monitoring and
conventional modems must be fitted before
the
Art.380N/UK
and not after.
A new master socket can be fitted after the
Art.380N/UK
(connected into terminals T1
and T2) and the telephone connected into the
master socket, see
Fig.4
.

BROADBAND
On installations with broadband and other
digital signals it is important to connect the
Art380N/UK
into an ADSL broadband filter,
see
Fig.5
.
Any broadband signals will then be filtered
off to the appropriate broadband and digital
devices and the analogue telephone signal
can pass through the
Art.380N/UK
and out
through to the new master socket.
When connected in this way an incoming
call from the entry panel
will only
ring the
master telephone socket and secondary
telephone socket that is connected after the
Art.380N/UK
. Incoming broadband signals
will only
pass through the digital side of
the ADSL broadband filter. An incoming call
from the entry panel
will not
ring any sockets
connected on this side of the filter.
