Step by Step
Configuration
Circuit
‐
switch
communication
requires
the
Raven
to
be
in
PassThru
mode,
communicating
directly
with
the
internal
hardware.
Note: When the Raven is used
for circuit switch, the circuit
switch configuration will disable
all ALEOS features except for
serial port communication.
PassThru
mode
disables
the
use
of
ALEOS
in
the
modem.
Any
features
available
using
ALEOS
are
not
usable
when
the
modem
is
in
PassThru
mode.
In
PassThru
mode,
the
settings
available
are
those
of
the
internal
hardware.
The
Raven
N3213
in
PassThru
mode
can
not.
The
best
machines
for
use
in
circuit
‐
switched
mode
are
ones
that
can
provide
their
own
INIT
or
setup
strings
and/or
issue
AT
commands.
For
customers
who
have
unintelligent
machines
who
still
need
to
have
the
modem
ʹ
ready
ʹ
to
behave
in
a
certain
way
(such
as
Auto
‐
Answering
circuit
‐
switched
data
calls),
there
is
a
feature
in
the
modem
called
the
INIT
STATE.
For
iDEN,
circuit
‐
switched
configuration
requires
an
account/
SIM
specifically
configured
for
a
Circuit
‐
Switched
Data
(CSD)
plan
with
no
restriction
on
inbound
or
outgoing
calls.
A
SIM/
account
provisioned
only
for
standard
data
options
will
not
work
for
CSD.
Configuring Circuit-Switch
The
Raven
needs
to
be
configured
to
enter
into
PassThru
after
start
up.
You
can
use
AceManager
(preferred)
or
direct
serial
communication
to
configure
the
Raven
to
work
in
PassThru
mode
and
for
circuit
‐
switched
communications.
In
the
UDP
group,
select
the
MD
command
and
choose
07
‐
PassThru
.
