Selector No. 1 2 3 4 5 6 7 8 WSW09 (Protocol definition 1) Function Frame length selection Use of non-standard commands No. of retries T5 timer T1 timer Elapsed time for time-out control for no response from the called station in automatic sending mode Setting and Specifications 0: 256 octets 1: 64 octets 0: Allowed 1: Prohibited No. 3 4 0 0 0 1 1 0 1 1 : 4 times : 3 times : 2 times : 1 time 0: 300 sec. 1: 60 sec. 0: 35 sec. 1: 40 sec. No. 7 8 0 0 0 1 1 0 1 1 : 60 sec. (55 sec. for US and Canada) : 140 sec. : 90 sec. : 35 sec. NOTE: Selectors 1 through 6 are not applicable in those models which do not support ECM. • Selector 1: Frame length selection Usually a single frame consists of 256 octets (1 octet = 8 bits). For communications lines with higher bit error rate, however, set selector 1 to "1" so that the facsimile equipment can divide a message into 64-octet frames. Remarks: The error correction mode (ECM) is a facsimile transmission manner in which the equipment divides a message into frames for transmission so that if any data error occurs on the transmission line, the equipment retransmits only those frames containing the error data. • Selector 2: Use of non-standard commands If this selector is set to "0," the equipment may use non-standard commands (the machine's nativemode commands, e.g., NSF, NSC, and NSS) for communications. If it is set to "1," the equipment will use standard commands only. • Selectors 3 and 4: No. of retries These selectors set the number of retries in each specified modem transmission speed. • Selector 5: T5 timer This selector sets the time length for the T5 timer. • Selector 6: T1 timer This selector sets the time length for the Ti timer. • Selectors 7 and 8: Elapsed time for time-out control If the equipment receives no response (no G3 command) from the called terminal in automatic sending during the time set by these selectors, it disconnects the line. 13

Selector
1:
Frame
length
selection
Usually
a
single
frame
consists
of
256
octets
(1
octet
=
8
bits).
For
communications
lines
with
higher
bit
error
rate,
however,
set
selector
1
to
"1"
so
that
the
facsimile
equipment
can
divide
a
message
into
64
-octet
frames.
Remarks:
The
error
correction
mode
(ECM)
is
a
facsimile
transmission
manner
in
which
the
equipment
divides
a
message
into
frames
for
transmission
so
that
if
any
data
error
occurs
on
the
transmission
line,
the
equipment
retransmits
only
those
frames
containing
the
error
data.
•
Selector
2:
Use
of
non-standard
commands
If
this
selector
is
set
to
"0,"
the
equipment
may
use
non-standard
commands
(the
machine's
native
-
mode
commands,
e.g.,
NSF,
NSC,
and
NSS)
for
communications.
If
it
is
set
to
"1,"
the
equipment
will
use
standard
commands
only.
•
Selectors
3
and
4:
No.
of
retries
These
selectors
set
the
number
of
retries
in
each
specified
modem
transmission
speed.
•
Selector
5:
T5
timer
This
selector
sets
the
time
length
for
the
T5
timer.
•
Selector
6:
T1
timer
This
selector
sets
the
time
length
for
the
Ti
timer.
•
Selectors
7
and
8:
Elapsed
time
for
time-out
control
If
the
equipment
receives
no
response
(no
G3
command)
from
the
called
terminal
in
automatic
sending
during
the
time
set
by
these
selectors,
it
disconnects
the
line.
