INET
Telephone Internet communicator.
Is intended for transmission of messages in the ADEMCO CONTACT ID format that were obtained from the telephone output of the electronic security switchboards to the remote centralized security switchboard (CSS) of RADOM SECURITY. Communication with CSS takes place through UDP/IP packets on an Ethernet interface.

Description INET
The equipment monitors the connection with CSS at regular intervals and in the case of its disruption, provides feedback information to the EZS, adjustably on one of two binary outputs.
The communicator further enables back-up of the transmission path in the event of loss of communication with the CSS by switching the EZS switchboard telephone line to the public telephone network (VTS).
In case of need, the module enables one-way communication (for example, for reasons of topology/network configuration with limited functionality. In this mode instructions from the CSS cannot be transmitted to the module and the module is not capable of monitoring the state of communication with the CSS (communication is, in this case, traceable only from the side of the CSS).
