Bit Switches – 4

6 Reconstruction time for
the first line in receive
mode
0: 6s 1: 12s
When the sending terminal is controlled by a computer, there may
be a delay in receiving page data after the local machine accepts
set-up data and sends CFR. This is outside the T.30
recommendation. But, if this delay occurs, set this bit to 1 to give
the sending machine more time to send data.
Refer to error code 0-20.
ITU-T T.30 recommendation: The first line should come within 5 s of
CFR.
