ATCommands

V.8 is not supported by the remote modem.

When V.90 is enabled the speeds listed can be used to set the maximum speed. For example: AT+MS=12,1,300,38667

This sets the maximum V.90 speed to 38667. Only the maximum speed is applicable when using V.90. The minimum speed cannot be set.

If <max_rate> is greater than the highest rate supported by the modulation specified by <mod>, the modem automodes down from the highest rate of the selected modulation. For example:

+MS=10,1,1200,24000 selects automoding down from V.32 bis 14400 bps.

To emulate issuance of the N1S37=x sequence command, specify the modulation and the rate to start automoding down from using <mod> and <max_rate>, respectively. Set <min_rate> to 300 to allow automoding all the way down to V.21 300 bps. For example:

+MS=11,1,300,16800 selects automode starting at V.34 16800 bps (no comparable S37 command).

+MS=9,1,300,12000 selects automode starting at V.32 12000 bps (same as S37=10).

<min_rate>

Is an optional number which specifies the lowest rate at which the modem may establish a connection. The value is decimal is decimal coded, in units of bps, e.g., 2400 specifies the lowest rate to be 2400 bps. The default is 300 for 300 bps.

When using V.90 or K56flex, the minimum rate can not be specified.

<max_rate>

Is an optional number which specifies the highest rate at which the modem may establish a connection. The value is decimal coded, in units of bps, e.g., 14400 specifies the highest rate to be 14400 bps. The default is 56000 for 56000 bps.

<x_law>

Is an optional number which specifies the codec type. The option are:

0 = m-Law

1 = A-Law

When using V.90, the appropriate law is selected automatically and the user setting will be ignored.
