Data Mode AT COMMANDS

Table 18. Data Mode Command Descriptions (Continued)

Command	Default		Description
		Store Active Profile: This command causes the modem to store a subset of the active profile command
&Wn	0	and S-register configurations into the NVRAM user profile ‘n’.
		n = 0*	Store in user profile 0
		n = 1	Store in user profile 1
		Select Stored Profile on Power-up:This command selects the particular stored user profile from the
&Yn	0	NVRAM to be loaded into the active profile upon modem power-up.
		n = 0*	Select profile 0
		n = 1	Select profile 1
		Store Telephone Number: This command stores a telephone number up to 30 digits (including dial
		modifiers) in the NVRAM. To dial the stored telephone number, use the ATDS=m command. Use the &V
&Zn=x	none	command to see the stored telephone number.
		n = 0–3
		x = 0–9 A B C D # * T P R W @ , ! ;
		Auto-Retrain Control: This command controls whether the modem automatically initiates a modem
		retrain whenever the received data signal quality falls below a threshold that may affect data reliability.
%En	1	The value for ‘n’ is stored in the NVRAM.
		n = 0	Disabled
		n = 1*	Enabled
		Rate Renegotiation: This command selects whether the modem automatically initiates a change to a
		higher speed or lower speed depending on received signal quality (that is, rate negotiation). The modem
%Gn	1	always responds to any rate change initiated by the remote modem.
		n = 0	Disabled
		n = 1*	Enabled
		Generate Data Modem Calling Tone: This command allows the DTE to select whether the modem
		sends a 1300 Hz calling tone or V.8 calling tone when originating a data modem connection.
-Cn	0	n = 0*	Calling tone disabled
		n = 1	1300 Hz calling tone sent for all data modem connections
		n = 2	V.8 calling tone sent for V.34 modulation and 1300 Hz calling tone sent for all other
			modulations
