Special line considerations

for U.K
Using extension telephones (U.K.
1
only)
Your premises may already be wired with
parallel extension telephones (those
2
connected to sockets in other rooms in the
building), or perhaps you intend to add
extension telephones to your line. While the
simplest arrangement is a parallel
connection, there are some reasons why this
arrangement may cause problems.
The most common problem, is someone
picking up an extension telephone while the
machine is trying to send a fax.
Such problems can easily be eliminated, if
you arrange modification of your extension
7
wiring circuit, such that extension devices are
connected "downstream" of your machine, in
a master/slave configuration (see figure 2). In
such a configuration, this machine can
always detect whether a telephone is in use,
so it will not attempt to seize the line during
that time. This is known as "telephone off-
hook detection".
The inadvisable configuration is shown in
figure 1, and the recommended master/slave
configuration is shown in figure 2.

This new connection configuration can be
arranged by contacting BT, Kingston upon
Hull Telecommunications, your PBX

maintainer or a qualified telephone
installation company as appropriate. Simply
explained, the extension telephone circuit

should be terminated on a normal modular
plug (BT 431A style), which in turn should be
inserted into the modular socket of the white
"T"-shaped connector provided as part of the
line cord assembly.
