+CBST, Select Bearer Service Type

This command sets the GSM bearer service (data circuit duplex asynchronous and synchronous).

It chooses one of the bearer services, the data rate of the service (actually the modulation when

modem IWFs are used), and enables or disables the Radio Link Protocol.

Command
Type Syntax Response/Action Remarks
Set AT+CBST=[<speed>[,<
name>
[,<ce>]]]
OK
+CME ERROR: <err>
The Set command selects the bearer
service <name> with data rate <speed>
and the connection element <ce> to be
used when data calls are originated
(refer to GSM 02.02). Values may also
be used during mobile terminated data
call setup, especially in the case of
single numbering scheme calls.
Note:
For incoming calls, the bearer
service will be taken
automatically from incoming
parameters and not according
to the CBST Set command.
The G24 does not change the output,
but for incoming calls, the phone
works in automatic mode.
