Change NAM Selection +WNAM | Multi-Tech Systems CDMA Wireless Modem

Chapter 6 – Network Service Commands

Change NAM Selection +WNAM

Description: This command is used to request a change in the NAM (Number Assignment Modem) selection. The modem supports up to 4 NAMs. However, if a NAM is not fully programmed, the modem will not switch to the requested NAM. The default NAM for the modem is 1. The response to this command is only OK, and is no guarantee that the NAM will change. If the NAM selection request is accepted, the unsolicited command +WNAM: <nam> will be returned. If or when the actual NAM changes, the unsolicited command +WCNM: <nam> will be returned. See Unsolicited Result Codes in Chapter 3.

Values:	<nam>
	1: NAM 1
	2: NAM 2
	3: NAM 3
	4: NAM 4
	5: Auto NAM
Syntax:	Command syntax: AT+WNAM=<nam>
	Command	Possible Responses
	AT+WNAM=2	OK
	Note: Use NAM 2, if	+WNAM: 2

	AT+WNAM=3	OK
	Note: Use NAM 3, if	Note: No unsolicited response indicates that
	programmed	NAM 3 is not valid, thus no change in NAM.
