DATA
0: Decremented by 1
every time 10 consecu-
tive good lines are
received.
1: Disabled

4 (8)
5 (10)
6 (12)
0: This quality control function is enabled. Data errors caused
by a noisy line or defective machine are counted. If the count
reaches 10, the machine sends RTN to the other end in reply
to the post message command. As 10 good lines cause the
count to decrement, RTN will occur only in bad conditions.
1: The counter will not decrement; frequent RTNs may occur.
Line error counting is not done if ECM is being used.
If there are more error lines in the received page than the
threshold specified by these bits, the page is rejected. Values
in parenthesis are for Detail resolution. The error line counter
is decremented by one every time an error-free line is
received.
