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
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.

These phones are now connected as external
devices as shown on page 55, because they
are connected to the fax machine via the T-
connector.
Using a non-Brother cordless
external handset 7
If your non-Brother cordless telephone is
connected to the telephone line cord (see
page 55) and you typically carry the cordless
handset elsewhere, it is easier to answer
calls during the Ring Delay.
If you let the machine answer first, you will
have to go to the machine so you can press
Tel/R to transfer the call to the cordless
handset.
Using Remote Codes 7
Remote Activation Code 7
If you answer a fax call on an extension or
external telephone, you can tell your machine
to receive it by pressing the Remote
Activation Code l51. Wait for the chirping
sounds then replace the handset. (See Fax
Detect on page 49.) Your caller will have to
press start to send the fax.
If you answer a fax call at the external
telephone, you can make the machine
receive the fax by pressing Start.
