NOTE: Selectors 1 through 5 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
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
If this selector is set to "0," the equipment may use
•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 T1 timer.
•Selectors 7 and 8: Elapsed time for
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.
