Certified dialling numbers
• Dialling numbers of fixed/mobile telephones and modems from
which a remote access is to be granted to the device.
• 8 access numbers are possible.
• If no numbers are entered, access is possible from any dialling
number.
• The dialling number must have the format +49123456789; no
blanks or special characters are allowed.
If one or several numbers are entered here, access to the device
can only be realised from one of these numbers. It should always
be tested whether your dialling number is transmitted. If the
dialling number is suppressed by the telephone or by the provider,
no remote access to the IE-GPRS-I/O is possible from this device.
NO remote access to the device will be possible in case of
incorrect settings or incorrect entries for the numbers.
Call accept
~ Data mode
• If you use a SIM card that does not possess a data number, it is
nevertheless possible to accept the call in the data mode if this
feature is set.
• Call acceptance in the "Data" mode, however, requires that the
data mode is enabled for incoming calls for your SIM card by the
mobile telephone provider.
~ Voice mode
• If the call is accepted in the "Voice" mode, it is possible to accept
the next call in the "Data" mode via telephone using the key
9
provided that you have dialled successfully in the "Voice" mode -
see temporary data mode for GSM devices.
