 Selectors 2 and 3: Allowable training error rate
The called station checks a series of zeros gathered in training (as described in Selector 1)
according to the allowable training error rate set by these selectors. If the called station
judges the line condition to be accepted, it responds with CFR; if not, it responds with FTT.
 Selectors 4 and 5: Decoding error rate for transmission of RTN
The machine checks the actual decoding errors and then transmits an RTN according to
the decoding error rate (Number of lines containing an error per page ÷ Total number of
lines per page) set by these selectors.
 Selector 8: Limitation of attenuation level
Setting this selector to "0" limits the transmitting level of the modem to 4 dB. This setting
has priority over the settings selected by WSW02 (selectors 5 through 8) and WSW13
(selectors 5 through 8).
