The machine changes the modulation parameters in
the MPh signal to lower the initial modem rate
during V.34 reception. If this switch is set to “0111”,
the machine lowers the initial speed one step, for
example, from 28,800 to 26,400 bps.
This switch reduces transmission time if the
machine frequently sends PPR signals during V.34
reception.

CNG transmission OFF interval
To input a value more than 3 s,
use bits 3 to 0, and keep bits 4
to 7 at 0
3000 + 50 x N ms
To input a value less than 3 s,
use bits 4 to 7, and keep bits 0
to 3 at 1
3000 – 50 x N ms
Examples.
3100 ms: 50 x 2 = 100
Bits 4 to 7 must be 0
Bits 0 to 3 must be 2(H)
So, enter 02H
2800 ms: 50 x 4 = 200
Bits 0 to 3 must be F(H)
Bits 4 to 7 must be 4(H)
So, enter 4FH
