 Intro
Most of the businesses have existing investments made in traditional wired-line telecom infrastructure known as Plain Old Telephone Service (POTS). This investment could be in the form of PBX, phones and wiring. Recently, GSM has emerged as a viable alternative to this fixed-line network and offers distinct advantages of its own. Today's businesses expect the specific benefits from GSM and POTS without sacrificing the existing well-running POTS infrastructure. Business organizations having access to both these networks need to bridge and interconnect them. This allows them to dynamically select one of the networks on per-call basis for obvious benefits of cost and Quality of Service (QoS).

Matrix Simado GFX44 is one such GSM gateway equipment offering interfaces for multiple GSM ports and FXS ports. It can be used with any brand of existing PBX or even in a stand-by mode. There is no need to change any aspect of the existing telephony infrastructure. Matrix Simado GFX44 works as an adjunct. Simado GFX44 supports flexible routing options providing significant cost savings and round-the-clock connectivity.
Let Matrix Simado GFX44 add a competitive edge to your business by reducing telephone costs!

Matrix Simado GFX44 is a gateway to interface GSM and Plain Old Telephone System (POTS) networks. On the GSM side, it supports quad-band operation allowing it to work with any GSM network. On the POTS side FXS interfaces are supported. Incoming calls on GSM ports can be routed on FXS ports. Outgoing calls from FXS are routed on GSM ports depending on the least cost routing logic. It can handle calls on all the ports simultaneously allowing full traffic on all the ports.

Existing PBX users can avail the low tariff of GSM networks by connecting Simado GFX44 with the PBX without changing their existing infrastructure. The users continue to make and receive calls without worrying on which network their calls are routed. Matrix Simado GFX44 routes the calls either on GSM network depending on the destination numbers dialed by the users. In addition, Simado GFX44 can also be used without a PBX in a stand-alone mode.

Intelligent and flexible routing is forte of the Matrix Simado GFX44. Least Cost Routing (LCR) algorithm encompasses dialed number based routing selects the most cost-effective route. Numbers received from calling network are converted by Automatic Number Translation (ANT) to match with the numbering plan of the destination network.

The Simado GFX44 is very easy to install and operate. In addition, the Jeeves (a Windows based multi-lingual GUI tool) is supplied to configure various parameters. Antenna mixers (4 to 1) are built-in and hence only one antenna is required. The Simado GFX44 can be mounted on a wall or any table surface.

 Key Features
Allowed and Denied Lists
Allowed and Denied Lists are used to restrict dialing of long-distance and international numbers. A number is blocked if its prefix matches any entry in the Denied Lists. On the other hand, a number is allowed to go through if it matched with any entry of Allowed List. This provides flexibility of allowing only specific numbers blocking all others.

Automatic Call Distribution
Simado GFX44 offers different schemes to select destination port for an incoming call. They are First Free, Round Robin, and Least Cost etc.

Port Status
Simado GFX44 monitors availability of all the ports continuously. If a port is not available for any reason, Simado GFX44 routes the call on the next best-fit port.

Automatic Number Translation
Matrix Simado GFX44 modifies the incoming number or part thereof so that it matches with the numbering plan of the destination network. For example, GSM networks require dialing of complete numbers including the area codes. If a caller has dialed just the local number, the Simado GFX44 adds area code as appropriate prefix.

Call Detail Recording (CDR)
Matrix Simado GFX44 stores up to 2000 calls made through the gateway in its internal memory. Reports can be generated on the COMM port using filters like Port, Number, Date, Duration, etc.

Call Progress Tones and Rings
Simado GFX44 provides programmable Call Progress Tones like Dial Tone, Ring Back Tone and Busy Tone etc. Country-specific tones can be selected to match the tones of the country where it is getting installed. Similarly, Ring cadences can also be selected.

Calling Party Control (CPC)
Simado GFX44 can send Calling Party Control call release signal on its FXS ports. This signal is then sensed by PBX or other equipment to release the ports when a call is terminated by the party on the GSM side of the network. This prevents ports getting stuck.

Caller Line Identification Presentation (CLIP)
Simado GFX44 supports CLIP on FXS and GSM ports. A port can be programmed to receive or send CLIP using any of the protocols like DTMF, FSK ITU-T V.23 and FSK Bellcore 212A.

Compact and Sturdy
Simado GFX44 is integrated gateway equipment. It can be installed on a wall or any table surface.

Day Light Saving
The Real Time Clock (RTC) of the Simado GFX44 moves forward or backward automatically in tune with the Day Light Saving requirements of the country.

Returned Calls to Original Caller (RCOC)
Matrix Simado GFX44 maintains records of all the unsuccessful calls on GSM network due to No Answer and such conditions. When such a call is returned, it routes the call to the original caller.

Fixed Number Dialing
Preconfigured number can be dialed out as soon as a call lands on a port. This allows point-to-point connectivity without the repeated need of dialing the same number.

International Mobile Equipment Identity (IMEI)
International Mobile Equipment Identity (IMEI) number provided on Simado GSM engine is a unique 15 digit code to identify an individual GSM port. This number can be used to associate the GSM port with a particular GSM network.

Jeeves
Jeeves is a Windows based GUI software tool for programming the Simado GFX44. It is intuitive, user friendly and supports many languages like English, French, Spanish, German, Russian, Portuguese, Italian and Russian.

Least Cost Routing (LCR)
The Simado GFX44 selects a port that is offering the least cost for an outgoing call. It supports LCR algorithms based on dialed Number. It selects the most cost-effective among GSM ports. Thus, each call can be routed on the most economical route.

LED Indications
A dual-color LED is provided for each FXS ports. They indicate current status of calls on these ports. There are one LEDs for each GSM port for Network and call status.

Network Selection
Each GSM port can be programmed to work only with a few selected networks preventing a GSM port from registering with an overlapping but costly network. This flexibility is very useful when Simado GFX44 is installed near a state or national border.

PCM-TDM Platform
The Simado GFX44 uses digital switching platform based on PCM-TDM concepts. This architecture provides better speech quality and higher noise immunity.

Remote Programming
It is possible to change the configuration of the Simado GFX44 from anywhere in the world. System engineer can log-in on any of the ports and enter in the programming mode after dialing password.

SIM PIN
Simado GFX44 allows user to program 4 digits PIN number (Personal Identification Number) which prevents the SIM against unauthorized use. User has to enter PIN for making any operations. User can change the SIM PIN as and when required. SIM gets blocked if PIN is entered wrongly thrice in a row.

Speech Gain
SimadoGFX44 allows user to set transmit and receive gains of GSM port to improve quality of speech.

Time Zones
Call routing can adapt to different routing needs during day time, lunch time and night hours. Four different time zones can be programmed and each port can be programmed to behave differently in each time zone.

Universal Routing
A call received on a GSM port can be routed on any FXS or even another GSM port. Similarly, as incoming call on an FXS port can be routed to any GSM port or even another FXS port.
