 Intro
Different telecom networks offer advantages in different aspects. Today's businesses expect the specific benefits from each of these networks. The Plain Old Telephone System (POTS) and GSM are two such omni-present networks. Most establishments have access to both these networks and need to bridge and interconnect them. This allows them to dynamically select one of the networks on per-call basis for the obvious benefits of cost and Quality of Service (QoS).

The Matrix Simado GFX888 is one such GSM Gateway equipment offering interfaces for multiple GSM, FXS and FXO ports. It can be used with any brand of existing PBX or even in a stand-alone mode. Simado GFX888 supports flexible and intelligent Least Cost Routing (LCR) options providing significant cost savings and round-the-clock connectivity.

Let the Matrix Simado GFX888 add that competitive edge to your business by reducing telephone costs!


The Matrix Simado GFX888 is a gateway (GSM PSTN Gateway) to interface GSM and Plain Old Telephone System (GSM POTS Gateway) networks. On the GSM side, it supports quad-band operation allowing it to work with any GSM network. On the POTS side both, FXS (GSM FXS Gateway) and FXO (GSM FXO Gateway) interfaces are supported. Incoming calls on GSM ports can be routed on FXS or FXO ports. Outgoing calls from FXS are routed either on GSM ports or FXO 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 of the low tariff of GSM networks by connecting Simado GFX888 with their existing PBX without changing its infrastructure. The users continue to make and receive calls without worrying on which network their calls are routed. The Simado GFX888 routes the calls either on POTS or GSM network depending on the destination numbers dialed by the users. In addition, the Simado GFX888 can be used without a PBX in a stand-alone mode.

Intelligent and flexible routing is the forte of the Simado GFX888. Various Least Cost Routing (LCR) schemes are offered. The elaborate routing algorithm encompasses different attributes like Port, Calling Number, Called Number and Time. It selects the most cost-effective route for a given number at a specified time. The numbers received from calling network are converted by Automatic Number Translation (ANT) to match with the numbering plan of the destination network.

The Matrix Simado GFX888 is very easy to install and operate. In addition, Jeeves, a Windows based multi-lingual GUI tool, is provided to configure its various parameters. The SIM cards can be accessed from the front panel after removing a snap-in facia. Antenna mixers (4 to 1) are built-in and hence only one (GFX444) or two (GFX666 and GFX888) antennas are required. It also houses internal power supply and thus does not need external adaptor. The Simado GFX888 comes in a telecom standard 19” sub-rack. It can also be mounted on a wall or a table surface.

The Matrix Simado GFX888 is available in three configurations in combinations of 4, 6 and 8 ports of GSM, FXO and FXS namely - Simado GFX444, Simado GFX666 and Simado GFX888.

 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 matches with any entry in the Allowed List. This provides flexibility of allowing only specific numbers while blocking all others.

Analog Input Port (AIP)
Simado GFX888 provides an analog port where an external music source can be connected. The desired music or jingle can be played to the caller kept on hold.

Analog Output Port (AOP)
Simado GFX888 provides an analog port where external amplifiers and speaker can be connected. Callers can dial in and make announcements.

Automatic Call Distribution
Simado GFX888 offers different schemes to select the destination port for an incoming call. They are: First Free, Round Robin, and Least Cost.

Automatic Number Translation
Simado GFX888 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, Simado GFX888 adds the area code as the appropriate prefix.

Call Detail Recording (CDR)
The Simado GFX888 stores up to 200 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 Duration Control (CDC)
Duration of each call made through Simado GFX888 can be controlled. When the duration of a call exceeds the set time limit, the call is forcefully disconnected. Different time limits can be set on each port. This feature can also be used to release ports that are left open accidentally.

Call Progress Tones and Rings
Simado GFX888 provides programmable Call Progress Tones like Dial Tone, Ring Back Tone and Busy Tone, etc. These tones can be selected to match with the tones of the country standard where it is installed. Similarly, Ring cadences can also be selected.

Calling Party Control (CPC)
Simado GFX888 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 blocking of ports.

Caller Line Identification Presentation (CLIP)
Matrix Simado GFX888 supports CLIP on FXS, FXO and GSM ports. A port can be programmed to receive or send CLIP using any of the protocols like DTMF, FSK ITU-T and FSK Bellcore.

Compact and Sturdy
Simado GFX888 is an all-integrated gateway equipment. The 19” rack type design is easy to maintain and occupies less space. It can be installed on a wall or a table surface.

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

Digital Input Port (DIP)
A switch or a sensor like smoke detector can be connected to the Digital Input Port (DIP) of the Simado GFX888. When this sensor is activated, it dials out a pre-programmed number and delivers a voice message to the called person. This is a useful security feature.

Digital Output Port (DOP)
An equipment can be switched on and off from any remote place by connecting it to the Digital Output Port (DOP) of the Simado GFX888. The user can call in on any port and then dial the appropriate command to control the equipment.

Fixed Number Dialing
A preconfigured number can be dialed out as soon as a call lands on a port. This allows point-to-point connectivity without having to dial the same number repeatedly.

International Mobile Equipment Identity (IMEI)
International Mobile Equipment Identity (IMEI) number provided on Simado GFX888 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 GFX888. It is intuitive, user friendly and supports many languages like English, French, Spanish, German, Russian, Portuguese, Italian and Russian.

Least Cost Routing (LCR)
The Matrix Simado GFX888 selects a port that is offering the least cost for an outgoing call. It supports various LCR algorithms based on Number, Time and combination of these. Port-wise LCR logic not only differentiates between GSM and FXO ports, but also 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 and FXO port. They indicate the current status of calls on these ports. There are two LEDs for each GSM port one for NETWORK and the other for call status.

Network Selection
Each GSM port can be programmed to work only with a few selected networks, thereby preventing a GSM port from registering with an overlapping but costly network. This flexibility is very useful when Simado GFX888 is installed near a state or a national border.

PCM-TDM Platform
Simado GFX888 uses digital switching platform based on PCM-TDM concepts. This architecture provides better speech quality and higher noise immunity.

Port Status
Simado GFX888 continuously monitors the availability of all the ports. If a port is not available for any reason, Simado GFX888 routes the call on to the next best-fit port.

Power Fail Transfer
In case of power failure, Simado GFX888 connects the FXS ports with the FXO ports, so that users can make and receive calls, without being cut-off.

Remote Programming
The configuration of the Simado GFX888 can be changed from any part of the world. The system engineer can log-in on any of the ports and enter the programming mode with a password.

Returned Calls to Original Caller (RCOC)
Matrix Simado GFX888 maintains records of all unsuccessful calls on the GSM network due to No Answer and similar such conditions. In the event of such a call being returned, Simado GFX888 routes the call to the original caller.

SIM PIN
Simado GFX888 allows the user to program a 4-digit PIN number (Personal Identification Number) to protect the SIM against unauthorized use. The user has to enter PIN for making any operations. The user can change the SIM PIN as and when required. The SIM gets blocked if the wrong PIN is entered thrice.

Speech Gain
Simado GFX888 allows the user to set Receive and Transmit gains of GSM port to improve the quality of speech.

SMPS
Simado GFX888 comes with built-in, universal-input SMPS making it all-integrated enterprise-grade telecom equipment. It operates from 90-265V @ 47-63Hz and thus eliminates the external adaptor.

Time Zones
Call routing can adapt to the 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 FXS, FXO or even another GSM port. Similarly, a call received on any FXO port can be routed on an FXS, GSM or even another FXO port.

Voice Message Prompts
Callers can be greeted and guided with pre-recorded voice prompts. A voice prompt can be of 16 seconds and such 16 different prompts can be recorded. These prompts can be used for call progress tones, guidance menu and during programming.
