Data commands
+CBST – Bearer type selection
Description:
This command applies to both outgoing and incoming data calls, but in a different way.
For an outgoing call, the two parameters (e.g. <speed> and <ce>) apply, whereas for an
incoming call, only the <ce> parameter applies.
NOTE 1:
For incoming calls, if <ce> is set to T only and the network offers NT only or
vice versa, then the call is released.
NOTE 2:
The former values of 100 and 101 for <ce> are retained for compatibility pur-
poses but should no longer be used, values 2 and 3 should be used instead.
Syntax:
AT+CBST= <speed>, <name>, <ce>
