contain
an

This
modem

should
not
be
used
for
Telex
service.
The
modem
may
be
used
with

or
it
may
be
connected
directly
to
the
telephone
lines
via
either
of
the
RJ-11
jacks
on
the

back
panel.
NOTE:
Be
sure
to
have
the
necessary
approvals
from
the
telephone
company,
communications
authority,
or
PTT
before
connecting
to
the
telephone
network.

TERMINAL
CONFIGURATION
3.1
Keyboard
Layout
International
models
are
available
with
either
of
two
keyboards:
a
universal
CCITT #2
(Baudot)
arrangement,
or
a CCITT #5
(ASCII)
configuration.
These
keyboards
are
illustrated
in
Appendix
A.
The
Baudot
keyboard
is
suitable
for
use
world-wide
without
keycap
substitution.
The
national
character
variants
are
represented
on
the
Baudot
keyboard
by
the
symbols
D,
8,
and
IZf
which
appear
on
the
top
row
of
the
keyboard.
These
keys
take
on
specific
national
character
meanings
depending
on
which
national
character
set
the
machine
is
prompted
for.
ASCII
(CCITT
#5)
teleprinters
are
normally
supplied
with
a
United
Kingdom
keyboard
layout
and
character
set.
In
case
it
is
necessary
to
change
this
layout,
a
keycap
remover
and
a
full
set
of
optional
keycaps
are
supplied
with
each
ASCII
international
teleprinter.
The
complete
set
of
keyboard
layouts
supported
by
the
terminal
is
given
in
the
Appendix
of
this
document.
Figure
3-1
shows
how
to
use
the
keycap
remover.
Simply
use
the
remover
to
grasp
the
underside
of
the
keycap,
then
pull
up.
Press
the
new
keycap
into
place.

The
Request
to

conductor
is
used
to
signal
the
data
transmission
equipment
to
condition
itself
for
data
transmission.
The
RTS
conductor
is
ON
when
the
terminal
is
in
the
LINE
mode
and
OFF
when
the
terminal
is
in
the
LOCAL
mode.
The
Clear
to
Send
conductor
is
used
to
signal
the
terminal
that
the
data
transmission
equipment
is
capable
of
sending
data.
The
CTS
circuit
can
optionally
be
recognized
or
ignored
as
a
condition
for
data
transmission
on
the
TD
circuit.
If
the
CTS
circuit
is
optionally
recognized,
CTS
must
be
ON
for
data
transmission
to
occur
on
the
TD
circuit.
If
the
CTS
circuit
is
optionally
ignored,
the
state
of
the
CTS
circuit
does
not
affect
trans-
mission
on
the
TD
circuit.
If
the
CTS
circuit
is
recognized,
its
logical
state
can
be
inverted
from
its
normal
state
by
terminal
option:
Normal
ON: +12V
Inverted
ON:
-12V
The
Data
Set
Ready
conductor
is
used
to
signal
the
terminal
that
the
communication
equipment
is
connected
to
the
communication
channel.
The
Data

circuit
must
be
ON
for
the
DTR

to
remain
ON.
Disconnect
will
occur
if
DSR
goes

If
the

has
been
optioned
for
the

mode,
DSR
going
OFF
will
cause
DTR
to
go
off
until
DSR

The

will
be
removed
from
the

mode
and
placed
in
the
LOCAL

When
the
terminal
has
been
placed
in
the

DTR
will
be
turned
on
as
a
condition
for
capture
by
activity
on
the
RI
circuit
or
on
the
RD
circuit.
If
the
terminal
has
been
optioned
for
the
non-capture
mode,
DSR
going
OFF
will
cause
DTR
to
go
off
until
DSR
goes

The

will
remain
in

LINE
mode.
The
Signal
Ground
conductor
es-
tablishes
a common
ground
reference
potential
for
all
interchange
circuits,
except
Protective
Ground.
The
Received

Signal
Detector
is
used
to
signal
the
terminal
that
a
carrier
frequency
has
been
placed
on
the
communica-
tion
link
and
that
data
can
be
or
is
being
sent
to
the
terminal.
The
RLSD
circuit
must
be
ON
for
the
terminal
to
receive.
A
character
for
character
check
of
RLSD
is
made
for
the
ON
state.
A
transition
of
RLSD
from
ON
to
OFF
will
inhibit
received
data,
but
will
not
disconnect
the
terminal.
If
the
terminal
is
in
the
capture
mode,
a
transition
of
RLSD
from
OFF
to
ON
and
presence
of
data
on
the
RD
circuit
will
cause
the
terminal
to
automatically
be
placed
in
the
LINE mode
from
the
LOCAL
mode.

The
Secondary
Request
to
Send
conductor
is
used
as
an
optional
data
pacing
circuit.
When
the
data
pacing
option
is
enabled,
an
SRTS
ON
state
indicates
that
data
transfer
can
occur.
When
SRTS
is
in
the
OFF
state,
the
terminal
is
not
capable
of
receiving
data
transfer.
The
Data
Terminal
Ready
conductor
is
used
to
indicate
the
terminal's
readiness
to
communi-
cate
on
the
communication
link.
The
DTR
circuit
will
be
placed
in
the
ON
state
when
the
terminal
is
placed
in
the
LINE mode.
If
the
terminal
is
in
the
capture
mode, a
transition
of
OFF
to
ON
of
DTR
will
occur
upon
a
transi-
tion
of
RI
from
OFF
to
ON
when
connected
to
an
external
modem,
or
upon
the
presence
of
data
on
the
RD
circuit,
and
DSR
or
RLSD
ON
when
connected
back-to-back
with
another
EIA
port.
DTR
will
be
prevented
from
turning
ON
if
Low
Paper
or
Paper
Out
states
exist
in
the
terminal.
If
DTR
is
ON,
and
either
Low
Paper
or
Paper
Out
occurs,
DTR
will
be
turned
OFF,
causing
a
disconnect,
if
the
terminal
is
ON-LINE.
The
Ring
Indicator
is
used
to
signal
the
terminal
that
the
communication
link
is
receiving
a
ringing
signal.
If
the
terminal
is
in
the
capture
mode,
it
will
respond
by
turning
DTR
ON.
The
terminal
has
a
programmable
option
to
respond
to
RI
after
