This
signal is present only
if
the
required optional equipment is installed.
The line audio summing circuitry sums these signals plus
the
ALERT
TONE
AUDIO, RX2 AUDIO, SECURE
ALERT TONES, and SECURE RX AUDIO. The output
of the line audio summing circuitry is
the
LINE AUDIO signal
routed to the
wireline.
The select audio summing circuitry sums
the same
signals
as the
line audio
summing
circuitry. One of the outputs of the select audio summing circuitry is the
SELECT AUDIO signal
routed
to the
optional expansion module, local speaker of
a
Radio Metering Panel (RMP)
or
a
Diagnostic Metering Panel (DMP). The
SPEAKER AUDIO signal
is another output of the select audio summing circuitry.
This signal
is amplified and then routed
to
a
local speaker
ofa DMP/RMP.
The
MRTI
audio summing circuitry sums the same
signals
as the
line and
select
audio summing circuits. The OUT MRTI AUDIO signal is
the
output for
the
MRTI
audio summing circuitry and routed
to the
MRTI
board.
If
a
Secure board is installed,
CODED MOD AUDIO is routed
to the
final output
stage
via JU3
jumper.
If
the station is
a
Trunked system,
TKG
MOD AUDIO is routed
to the
modulator
via
the JUS
jumper.
If
the
optional General Communications Controller
(GCC)
is
installed,
GCC DATA
AUDIO
is routed from the expansion bus
to the
input
of
the
limiter (for
1200
baud)
via
the
JU14 jumper
setting
or to the
final output
stage (for 4800 baud)
via
the
JU6
jumper setting.
For data
station configurations
(using
the
Expansion Tray),
TX DATA AUDIO
is
routed
via
the expansion bus to the
input of
the
maximum deviation adjust circuit
or to the final output stage
via
the
JU4
jumper setting.
