GSM FWT GSM Interface (Etross-8848)

Etross-8848 is a GSM 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 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 extentions, to connect billing systems for public phone use, to connect VoIP 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 a Analog FXS phone line.

Features:
1) It is a 1 channel GSM Gateway which has 2 RJ-11 outputs for extensions;
2) It can connect with ordinary telephone set, PBX, VoIP Gateway, Billing meter etc.;
3) Dialing tone frequency: 450Hz;
4) Employ Industrial module [SIM300( Tri-band 900/1800/1900MHz), M10(Quadband 850/900/1800/1900MHz) or Q2403A(900/1800MHz), to make;
5) Can adjust dial interval from 0.5sec to 9 secs by setting up from telephone set; GSM fwt/gateway8) Caller ID display;
9) DTMF Dialing;
10) Bell signal;
11) Polarity reversal;
12) The RJ-11 socket which connect the phone or billing system for metering purpose;
13) Antenna socket (SMA);
14) IP Presetting;
15) Working status and Signal Strength by LED indicator; 16) IMEI Change (optional).
17) back up Li-ion battery( Optional) 7.2V 1300mAh. Standby 24hrs, talking time: 2.5hrs.

Installation And Connection
The Condition for Installation
The terminal asks for 110- 220V AV power supply. It must be installed in the area where the GSM network can cover. The strength of the signal can affect the quality of voice.
1. Screw off the screws that are on the back of the terminal, Insert SIM card for every SIM card holder, and then tighten the screws.
2. Install antenna. In order to ensure the quality of voice, antenna must be put beyond 1.5 from the telephone and terminal.
3. On end of the telephone line connects to the "Phone" port of the terminal, the other end connects to telephone.
4. "Power" port connects to power adapter that is connected to 110-220V AC power supply.
