Register Unit Range Default Description
S210 0–255 13 (0Dh) V.34 Symbol Rate. The bits in this parameter control V.34 symbols rates
and enable/disable V.34 asymmetric rates. This parameter is used for
diagnostic purposes only.
Default: 13 (0Dh) (00001101b)
Bits 0 -2 Selects the range of allowed V.34 symbol rates.
21
0 Symbol Rates (baud)
0 0 0 2400 only
0 0 1 2400 only (no 2734)
0 1 0 2400, 2800
0 1 1 2400, 2800, 3000
1 0 0 2400, 2800, 3000, 3200
1 0 1 2400, 2800, 3000, 3200, 3429 (Default.)
Bit 3 Enable/disable V.34 asymmetric rates.
0 = Disable asymmetric rates
1 = Enable asymmetric rates (Default.)
Bits 4-7 Reserved.
Examples
S210=13 Enable asymmetric rates with all symbol rates available
(Default.).
S210=5 Disable asymmetric rates with all symbol rates
available.
S210=8 Enable asymmetric rates with only 2400 baud available.
S210=11 Enable asymmetric rates with 2400 to 3000 baud
available.
