Chapter 1 – AT Commands, S-Registers and Result Codes

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.

mod value	Valid max_rate values (bps)

V92, V90, V34	31200, 28800, 26400, 24000, 21600,19200, 16800,
	14400, 12000, 9600, 7200, 4800, 2400
V32B	19200, 16800, 14400, 12000, 9600, 7200, 4800
V32	14400, 12000, 9600, 7200, 4800
V22B	2400
V22, V23C, Bell212A	1200
V21, Bell103	300

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
