The ITS-300GSM is used to automatically transmit control
panel reports via the analog telephone network with backup
transmission via the GSM network.
It is compatible with control panels from various
manufacturers with integrated communicator for the analog
telephone network.

Functions
Outgoing calls and reports are transmitted via the analog
telephone network as standard. The ITS-300GSM monitors
the telephone line statically and dynamically and switches
to GSM transmission under certain conditions.
Static monitoring
The voltage of the telephone line is checked regularly. If the
voltage is too low, the ITS-300GSM switches to GSM
transmission and activates the fault relay. This allows the
control panel to transmit the fault message via the GSM
network, if necessary.
Dynamic monitoring
Dynamic monitoring is activated during report
transmission. The switch to GSM transmission occurs if
manipulation of the telephone line is detected or after three
unsuccessful redial attempts from the control panel. After
successful transmission, the ITS-300GSM reverts to the
telephone line.
Backup path transmission
Backup path transmission via the GSM network is carried
out either transparently or as an SMS message. In the event
of transparent transmission, sent tones are transmitted
transparently in the voice channel to the phone number
dialed by the control panel. For SMS transmission, the
contact ID report is sent to an SMS receiver in the form of
an SMS message.
Calls from house phone
If the analog telephone network fails, calls from the house
phone can be allowed or disallowed via the GSM network
in accordance with the programming.
