GSM FWT-8818 is a GSM to Analog Converter, the device can produce a FXS line to allow a regular phone to be connected and used just like a local landline(PSTN) except your calls will go out the GSM network. This device can both receive and make calls.
The main application is: Connecting the RJ-11 FXS line to connect Ordinary telephone set for voice call, to connect PBX for call extensions, to connect billing systems for public phone use, to connect VoIP gateway to realize VoIP call termination, to connect alarm panels for security purpose, etc.
Especially, GSM FWT-8818 provide SMS management for SIM credit balance inquiry, Low battery alarm, SMS remote control for alarm panel, and SMS remote control for relay etc. So it is a better choice for alarm security application.
GSM 900/1800MHz dual band, employing SIM500W, SIM300W module to make;
