automode An optional numeric value that enables or disables automatic modulation negotiation using V.8 bis/V.8 or V.32 bis Annex A. Automode is disabled if values are specified for the max_rate and max_rx_rate parameters. The options are:

0Disable automode

1Enable automode (default)

max_rate An optional number that specifies the highest rate at which the modem may establish an upstream (transmit) connection. The value is decimal coded in units of bps, for example, 33600 specifies the highest rate to be 33600 bps.

0 Maximum rate determined by the modulation selected in mod (default).

300–33600Maximum rate value limited by the modulation selected in mod. For valid max_rate values for each mod value, see the following table.

max_rx_rate An optional number that specifies the highest rate at which the modem may establish a downstream (receive) connection. The value is decimal coded in units of bps, e.g., 28800 specifies the highest rate to be 28800 bps.

0 Maximum rate determined by the modulation selected in mod (default).

300–56000 Maximum rate value limited by the modulation selected in mod. See “Possible rates” in the mod table.

Command:

+PCW=n

Call Waiting Enable

Values:

n = 0, 1, or 2

Default:

2

 

 

Description:

Controls the action to be taken upon detection of a call waiting tone in V.92 mode. Values

 

specified by this command are not modified when an AT&F command is issued.

 

+PCW=0

Toggles V.24 Circuit 125 and collects Caller ID if enabled by +VCID

 

+PCW=1

Hangs up

 

+PCW=2

Ignores V.92 call waiting

 

+PCW=?

Displays the allowed values

 

+PCW?

Displays the current value

Command:

+PIG=n PCM Upstream Ignore

Values:

n = 0 or 1

 

Default:

1

 

 

Description:

Controls the use of PCM upstream during V.92 operation. PCM upstream allows faster

 

upload speeds to a V.92 server.

 

+PIG=0

Disables PCM upstream

 

+PIG=1

Enables PCM upstream

 

+PIG=?

Displays the allowed values

 

+PIG? Displays the current value

Command:

+PMH=n

Modem on Hold Enable

Values:

n = 0 or 1

 

Default:

1

 

 

Description:

Controls if modem on hold procedures are enabled during V.92 operation. Normally

 

controlled by a modem on hold program. Values specified by this command are not modified

 

when an AT&F command is issued.

 

+PMH=0

Enables V.92 modem on hold

 

+PMH=1

Disables V.92 modem on hold

 

+PMH=?

Displays the allowed values

 

+PMH?

Displays the current value
