TA selects the bearer service <name>, the data rate <speed> and the
connection element <ce> to be used when data calls are originated. The
settings also apply to mobile terminated data calls, especially when single
numbering scheme calls or calls from analog devices are received (see also
Chapter 4.41).

Note
· GSM 02.02[1]: List of allowed combinations of subparameters.
· The PLMN influences the second air interface (to the terminator), therefore
another mode may be established by the network.
· In multiplex mode (AT+CMUX Enter multiplex mode, pg. 86), the bearer
capabilities using 14400 bps (14,75) are not available. Incoming calls are
negotiated at 9600bps. If multiplex mode is active, the bearer capability
automatically switches to +CBST=7,0,1.
