GSM FCT for VOICE
Introduction
GSM network offers significant cost advantage and widespread coverage to the subscribers. This motivates organizations to switch to mobile networks. They want to use the GSM networks for making and receiving calls even during office hours from their desks using their existing PBX. The GSM FCT can be directly interfaced to existing PBX infrastructure. This allows the users to dynamically select between GSM and POTS networks, on per-call basis. Such a set-up is beneficial in corporate offices, factories, call centers, hotels, residences and other such establishments.
SIMADO GFX11 is one such GSM FCT. It sits between the GSM/3G and Plain Old Telephone System (POTS) networks. It supports GSM Quad-Band operation allowing it to work with any GSM network. On the POTS side, the FXS port can be connected to any existing PBX or telephone instrument. This allows a user to make and receive calls through the GSM line. Incoming calls on the GSM port are routed to the FXS port to reach the operator or any extension of the PBX. For outgoing calls, the PBX users continue dialing the numbers as if dialing on the normal trunk (CO) lines.
Access to long distance and international dialing can be controlled by programming Allowed and Denied Lists. This logic allows flexibility of allowing access to certain numbers while restricting to all others. Number Translation feature automatically adds area code as prefix to a number before dialing it out on the GSM. Moreover, features like Hotline, Signal Strength Indication and Location Information Indication and Network Selection are also supported.
Thus, the existing PBX users can avail the low tariff of GSM networks by connecting SIMADO GFX11 with the PBX without changing their existing infrastructure. In addition, Matrix SIMADO GFX11 can also be used in a stand-alone mode. Any standard telephone set can be easily plugged-in the FCTs FXS port. Inserting a SIM, the FCT can now route calls made from the telephone via the GSM network.

The GSM FCT for Payphones
The GSM FCT can be used in varied applications. Connecting a payphone to its FXS port, allows the payphone to be used anywhere within the GSM coverage range, which is inherently widespread. Calls from payphone users can now be placed using the cost-effective GSM network. The FCT also supports Polarity Reversal mechanism on its FXS port, to activate the payphone metering mechanism. The otherwise fixed payphone, now gains the GSM mobility and cost advantage.
