7.24 AT+CSNS Single Numbering Scheme
The AT+CSNS command enables the ME to accept incoming calls when no bearer capability information is pro-
vided with the call, e.g. single numbering scheme calls or calls originating from analog devices. 
Syntax
Parameter Description
[0]
(D)
Voice: Each call received without bearer element is assumed to be speech
2 Fax: Each call received without bearer element is assumed to be an incoming
fax.
4 Data: Each call received without bearer element is assumed to be a data call.
Please take into account that the bearer service parameters set with AT+CBST
apply to all data calls including those received without bearer capability. 
Notes
• The command must be set before the call comes. By default, when you do not modify the settings, all calls
received without bearer element are assumed to be voice. 
• The setting will be saved when you power down the ME with AT^SMSO, provided that PIN authentication has
been done. The saved value will be restored when the same SIM card is inserted and PIN authentication done
again. If no SIM card or a different SIM card is inserted the default value 0 takes effect.
