Notes:
1.See optional <automode>, <min_RX_rate>, <max_RX_rate>, and <max_TX_rate> subparameters.
2.Selects V.90 modulation as first priority. If a V.90 connection cannot be established, the modem attempts K56flex, V.34, V.32bis, etc. (Default.)
3.Selects K56flex modulation as first priority. If a K56flex connection cannot be established, the modem attempts V.90, V.34, V.32bis, etc.
x_law An optional number that specifies the PCM code type for 56K modulation. The options are:
0=
1=
The modem automatically selects
| reserved Must not be changed from the default value of 0. |
| max_TX_rate An optional number that specifies the highest |
| rate at which the modem may establish a transmit connection. |
| The value is decimal coded in units of bps, e.g., 33600 specifies |
| the highest rate to be 33600 bps. See “Possible rates” in the mod |
| table. The default is 33600, for 33600 bps. |
Command: | MNP Extended Services |
Values: | n = 0, 1, or 2 |
Default: | 0 |
Description: | Enables or disables conversion of a V.42 LAPM connection to |
| an MNP 10 connection. |
Disables V.42 LAPM to MNP 10 conversion. | |
Enables V.42 LAPM to MNP 10 conversion. | |
Enables V.42 LAPM to MNP 10 conversion; inhibits MNP | |
| Extended Services initiation during V.42 LAPM answer mode |
| detection phase. |
