Bit 2 Enable +MCR: XXXX result code (XXXX = modulation) and +MRR: XXXX

result code (XXXX = rate). (Also, see +MR.)

Bit 3 Enable +ER: XXXX result code (XXXX = protocol identifier).

Bit 4 Reserved.

Bit 5 Enable +DR: XXXX result code (XXXX = compression type).

Bits 6-7 Reserved.

11.40 S210 – V.34 Symbol Rates

The bits in this parameter control V.34 symbol rates and enables/disables V.34 asymmetric rates.

This parameter is used for diagnostic purpose only.

Default: 13 (0Dh) (00001101b)

Bits 0 -2 Selects the range of allowed V.34 symbol rates.

2 1 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.
