Idle Connection Control with Data Transmit Control
Data Transmit Control (DTC) is a function of the INSYS GSM 4.3 which monitors
the data transmission in online mode. This function prevents the INSYS GSM 4.3
from staying online for an unlimited amount of time, although no data is being
transmitted anymore. The DTC function can define the time after which the INSYS
GSM 4.3 will hang up as soon as there is no data transfer on the phone line.
Configuration with HSComm
In order to enable Data Transmit Control, enter the time, after which the
INSYS GSM 4.3 shall hang up in case of missing data transmission on
the Basic Settings” tab on the “GSM Connection” panel into the entry
field “idle connection control”.
Configuration with AT commands
To define the time, after which the INSYS
GSM 4.3 should hang up, if no data trans-
mission is available, use the command
You can select a value between 1 and 255
seconds for
<n>
. Please note that the timer
will start running, as soon as the INSYS
GSM 4.3 goes off-hook (“Connect” LED
illuminates). We therefore strongly recom-
mend not to configure a time less than
20 seconds.
