SC-688-3G WCDMA FWT

Voice only for both GSM 2G and 3G networks

1, General Description

SC-688-3G FWT  is a WCDMA to Analog Converter(single port, insert 1 sim card only), the device can produce a FXS line to allow a regular phone to be connected and u sed 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 FXO gateway to realize VoIP call termination; to connect alarm system for security purpose, etc. It is not a VOIP gateway, nor a GSM+VOIP gateway, It is a GSM Fixed Wireless Terminal that produces an analog FXS phone line .
