10.4.1 Effect of parameter
Once the last service has been closed the bearer shuts down after a timeout of 20 seconds (i.e. the connection
profile GPRS0 or CSD is closed). If a service related to the same connection profile starts up again whithin this
time frame, the bearer will not be closed, but started again. This speeds up the handling of several service
requests. Within this time frame it is neither possible to change the bearer type (from GPRS to CSD or vice versa)
nor to start a service based on a different connection profile.
To disconnect the bearer before the timeout expires the command
AT+CGATT
=0 can be used in the case of
GPRS and
ATH
in the case of CSD.
