Actiontec electronic V.90 manual Modulation Selections

%G0: Disabled.

%G1: Enabled.

-Cn Data Calling Tone

Data Calling Tone is a tone of certain frequency and cadence as specified in V.25 which allows remote Data/FAX/Voice discrimination. The frequency is 1300 Hz with a cadence of .5 s on and 2 s off.

-CO: Disabled.

-C1: Enabled. (default)

-C2: Enable V.8 and 1300 Hz calling tone.

+MS=m Modulation Selections.

This Command selects modulation standards and transmit-receive speeds. To dis- play the current setting, type AT+MS?. The proper command syntax is:

AT+MS=<carrier>,<automode>,<min rate>,<max rate>

<carrier> This parameter specifies the type of modulation standard used. The list below shows approved codes:

V21 V.21 (300 bps)

V22 V.22 (1200 bps)

V22B V.22 bis (1200 and 2400 bps)

V23C V.23, constant carrier (1200 bps forward and 300 bps reverse)

V32 V.32 (4800 and 9600 bps)

V32B V.32 bis (7200, 9600, 12200, and 14400)

V34 V.34 asymmetrical (2400, 4800, 7200, 9600, 12200, 14400, 16800, 19200, 21600, 24000, 26400, 28800, 31200, and 33600 bps)

V34S V.34 symmetrical only (2400, 4800,7200, 9600, 12200, 14400, 16800, 19200, 21600, 24000, 26400, 28800, 31200, and 33600 bps)

V34B V.34 extended asymmetrical (2400, 4800, 7200, 9600, 12200, 14400, 16800, 19200, 21600, 24000, 26400, 28800, 31200, and 33600 bps)

V90 V.90 asymmetrical [transmit speeds (4800, 7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000, 26400, 28800, and 31200 bps)]; [receive speeds (33333, 37333, 41333, 42667, 44000, 45333, 46667, 48000, 49333, 50667, 52000, and 53333 bps)]

<automode> This parameter allows the modem to negotiate modulation speeds automatically.

0= disabled (modem will not negotiate speeds automatically) 1= enabled (automatic negotiation allowed)
