REMOTE
(ENCODE)
The
System can be used
to
simulate a
tone
remote con-
trol console,
or
to troubleshoot tone
control
decoding
circuitry in remote base station. These useful
tone
bursts
are
available
at
the
MOD
OUT
jack
on
the
front
panel
so
that
they can be coupled
onto
phone
lines
or
any
other
place they
may
be
needed. Activate the
tone
bursts
by selecting
TONE
REMOTE
mode
in the
MODULA-
TION
section
of
the
front
panel. Select the two ap-
propriate
frequencies
of
the tone bursts by
program-
ming
Tone
A
and
Tone
B frequencies in the
Two-Tone
paging sequence. Typical
guard
tone frequency
(Tone
A) is 2175
Hz.
Function tones (Tone
B)
vary by system.
Select

Unlike the
other
signaling sequences, this special
mode
provides
no
repetitive sequences. Institute the
TONE
REMOTE
sequence by moving the
MODULATION
switch
to
BURST
or
CONTINUOUS.
The
sequence
issues
TONE
A for
115
ms followed by
TONE
B for 40
ms
at
a level 10 dB below
that
of
Tone
A.
Tone
A
follows
at
a level 30 dB below
that
of
the initial
Tone
A
for as long as the
MODULATION
Switch
is
held in
either the BURST
or
CONTINUOUS
position.
The
level
of
these bursts
is
adjustable with the
MOD
LEVEL
control,
and
may
be
observed with the
MODULATION
DISPLA
Y similar to any signaling sequence.
