Dial Setups when using V.35/X.21
Dial
setups
are
sometimes
used
as
a
"short
‐
cut"
method
of
changing
codec
parameters
when
using
the
V.35
option.
If
you
are
using
one
of
the
Xstream's
V.35
interface
modes
(see
Section
9
‐
V.35/X.21
Interface)
you
can
use
Dial
Setups
without
phone
numbers
to
conveniently
changes
modes.
When
a
setup
containing
an
entry
for
Number
1
or
Number
2
(i.e.
a
phone
number)
is
activated
and
the
Interface
(in
the
third
TEL
menu)
is
set
to
V.35
Split
or
V.35
single
the
system
will
change
the
interface
to
ISDN
so
that
the
number(s)
may
be
dialed.
This
arrangement
allows
for
externally
triggered
ISDN
backup
in
case
of
a
failure
of
to
a
dedicated
data
facility.
The
Panic
Dial
feature
could
be
used
to
activate
this
setup
by
an
external
device.
h
HOT TIP!
You are combining two features in this case, so be sure to understand the following:
-There is no method to use a setup to change from ISDN to V.35.
-Therefore, your external panic dial trigger source should remain asserted.
-You can manually switch back to V.35 and then drop the ISDN call to restore the V.35
connection.
-Telnet or RS-232 commands allow for more sophisticated control options.
Dial Setups using Panic Dial Closures
Configuring
an
input
to
use
panic
dial
is
covered
in
Section
11.6.
The
hardware
specifications
for
the
Parallel
Control
port
are
shown
in
Sections
3.2
&
3.4
(Guided
Tour
of
the
Hardware)
When
a
panic
dial
is
triggered
by
asserting
one
of
the
inputs,
the
system
takes
the
following
actions:
1.
Any
ISDN
call(s)
present
will
be
dropped
2.
The
Dial
Setup
indicated
for
the
input
asserted
will
be
triggered
•
If
one
or
more
telephone
numbers
are
present,
the
Interface
setting
(in
the
third
TEL
menu)
will
be
set
to
ISDN
.
•
If
the
setup
"includes"
CODEC
settings,
the
codec
will
be
configured
to
the
settings
stored
when
this
Dial
Setup
was
created.
•
The
number
entered
as
"number
1",
if
present,
will
be
dialed.
•
If
the
first
call
completes
the
second
call
will
be
attempted
(if
two
numbers
are
present)
3.
The
connection
will
be
maintained
until
the
input
is
no
longer
asserted.
