NOTE:
Selectors 1 through 6 are not applicable in those models which do not support ECM.
l
Selector 1:
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 machine can divide a
message into 64-octet frames.
Remarks:
l
Selector 2:
If this selector is set to "0," the machine 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 machine will use standard commands only.
l
Selectors 3 and 4: No. of retries
These selectors set the number of retries in each specified modem transmission speed.
l
Selector 5:
This selector sets the time length for the T5 timer.
l
Selector 6:
This selector sets the time length for the T1 timer.
l
Selectors 7 and 8: Elapsed time for time-out control
If the machine receives no response (no G3 command) from the called terminal in automatic
sending during the time set by these selectors, it disconnects the line.

The error correction mode (ECM) is a facsimile transmission manner in which
the machine divides a message into frames for transmission so that if any data
error occurs on the transmission line, the machine retransmits only those frames
containing the error data.
