Line Condition 2 -
No
Sound
When nothing
happens
after a number
is
dialed, check
the number that
you stored
in
the dialer
memory
.
Or, maybe the problem
is
within
the telephone
company. The
modem
will
wait
for about
50
seconds before aborting a call
.
Then
the message
DEAD/
LI NE
is displayed. The modem
returns
to
an off-line
status
and enters
the
waiting state.
Send the
wake-up command
to
enter
the
command receptive state.
Line Condition 3 -
Busy Signal
The message BUSY
appears on your display when a
busy
signal is
detected
.
The
modem
disconnects
itself
from
the telephone lines
and
returns to the
off-line waiting
state
until it receives the wake-up
command.
If the
DIAL ATTEMPTS
parameter
of
the
modem
is programmed
for a
number
other
than 1
(the
defaulted number)
,
the busy
redial
sequence is
activated. Therefore, after
the first attempt, the
modem will
automatically wait for about 60
seconds, then
it
will
seize
the line, look
for a dial
tone, dial the number,
and
monitor the progress
of
the
call.
What happens
if
the
line is
still
busy on
the second
attempt?
Well
,
DC-2212 hangs
up
and starts
the
process
again
.
If the
modem
is
programmed for
two dial
attempts and
has tried twice
,
but
failed
to
complete
the
call, everything stops
here
and
the modem
enters the
off-line
state.
If programmed
for more than two dial attempts,
the modem
waits
for
60
seconds and
tries
again. The
modem
will
keep
trying
until the
attempts
count
is
completed
,
or
until the
call is completed. When completed
,
the
message
0
N LINE
0
RI
G
I NATE
is printed to the
display
.
Line Condition 4 -
Re-order Tone
The
re-order tone is
a
beeping tone the telephone
company
uses
to
tell you
that
something
is
wrong. Either your modem's
numeric data
was
not
valid, you
dialed too
fast,
or, for
some
reason, the
company can't process your call.
Since
the DC-2212
cannot
distinguish
a
re-order tone
from a
dial tone
,
it
will wait
the
full
time-out time
before
it
stops
looking
for a carrier condition
.
Dial Sequence Emergency Shutdown Command
When
you
discover that the modem
is
dialing an incorrect telephone number, or
you
don't want to wait
for the
time
out
to expire,
you can
turn
off the
dial
sequence.
