Alignment Procedures
NOTE
These recommended levels
are
intended for co-located
consoles
which do not have phone line loss. If other
levels
are
required due to phone line loss, the same
relative relationship of signal levels should
be
maintained.
CAUTION
Do not key the station
via RSS
or
by setting
the
LIN PTT MUXbus
bit since
these methods do no set
ALC
correctly.
Inject an
HLGT/FT
sequence
followed by
a
1
kHz
tone
with
LLGT
across
the
appropriate transmit wireline terminals, using
a
console or service
monitor.
3.
Line
1
+/- for four-wire systems or Line
2
+/-
for
two-wire
systems.
The station should
be
keyed. Proceed
to step 6.
Inject
a
1
kHz
tone across the
appropriate transmit wireline terminals at
a
level matching average audio
(-6
dBm),
or other levels relative to peak input
level.
4.
NOTE
The recommended level is intended for co-located
consoles
which do not have phone line loss. If
other
levels
are
required due to phone line loss, the same
relative relationship of signal levels should be
maintained.
5. Key
the station
by
setting
the
LIN PTT
MUXbus bit
(A1/D2).
Set and hold the
PL Dis/Xmit
switch
to
Xmit during
step
7.
This strips any data from being summed
with
the
transmit audio.
6.
Adjust
transmit audio level via
EEPOT
7
until
the transmitted
deviation
level
reaches 60%
full station deviation, as indicated in Table 4-8.
7.
Adjust
EEPOT E if
the
level cannot
be set
via EEPOT
7
alone. 7
Exit
the
EEPOT
adjust mode.

EEPOT
adjust mode.
