Automatic Call
The automatic call allows to initiate a call to a phone number previously stored in
the INSYS ISDN TA 4.0. There are three possibilities for initiating a call.
The call may be initiated by the DTR line of the serial interface or incoming data at
the serial interface. Additionally, the INSYS ISDN TA 4.0 can try to call a number
immediately after switching it on.
The phone number for the automatic call is taken from the dialing table "catab". If a
connection could not be established successfully, the INSYS ISDN TA 4.0 dials the
next number from the dialling list. If none of the target phone numbers from the
dialling list could be reached, the INSYS ISDN TA 4.0 initiates an automatic redial.
You can change the maximum number of attempts as well as the duration of the
pause until the next call.
9.3.1
Configuring an Automatic Call
In order to configure an automatic call, change to the Configurator mode of the
INSYS ISDN TA 4.0 and enter the target phone number first, then select the trigger
for the connection establishment and set the reset timer. The reset timer
determines the time from the reset of the INSYS ISDN TA 4.0 until the change to
the "automatic call" mode. If an automatic call is enabled, you have the possibility
to send AT commands to the INSYS ISDN TA 4.0 during this time. The INSYS ISDN
TA 4.0 does not accept AT commands anymore after you have configured and
enabled the automatic call. The reason for this is that incoming data are
immediately transmitted to the called remote terminal. An established connection
is indicated by the INSYS ISDN TA 4.0 by the "OH" LED and "DCD" LED on the
housing front.
The automatic call is disabled in default setting . The dialling table "catab" is empty.
Configuration with HSComm
A configuration with HSComm is not possible.
