The problem of limited connectivity of an alarm system is solved by providing an interface module in the form of a communication terminal for coupling to an alarm system that allows routing both analog and digital communications between the alarm system and a remote recipient through a digital network selected by the terminal and therefore independently from the alarm system. Embodiments of the communication terminal include an analog phone line emulator connectable to the alarm system, at least one digital network coupler such as a cellular module and an Ethernet port, and a controller coupled to both the at least one digital network coupler and to the analog phone line emulator for allowing communications therebetween. The terminal allows communicating alarm messages from the alarm system to an alarm central via the selected digital network and also allow VoIP communications to make phone calls and remote configuration of the alarm system, terminal or other devices connected thereto. |
