 Intro
Different telecom networks offer advantages in different aspects. Today's businesses expect the specific benefits from each of these networks. The ISDN and GSM are two such omni-present networks. Most of the 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 obvious benefits of cost and quality of service (QoS).

Matrix Simado GBR42 is one such GSM Gateway equipment offering interfaces for four GSM and two ISDN BRI ports. It can be used with any brand of existing PBX or even in a stand-alone mode. Simado GBR42 supports flexible and intelligent Least Cost Routing (LCR) options providing significant cost savings and round-the-clock connectivity.

Let Matrix Simado GBR42 (GSM BRI Gateway) add a competitive edge to your business by reducing telephone costs!



Matrix Simado GBR42 is a gateway to interface GSM and ISDN BRI networks. On the GSM side, it supports quad-band operation allowing it to work with any GSM network. The ISDN BRI port supports both TE and NT modes. Incoming calls on GSM ports can be routed on BRI TE or BRI NT and GSM ports. Outgoing calls from NT are routed either on GSM ports or on BRI TE 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 GBR42 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 GBR42 routes the calls either on ISDN or GSM network depending on the dialed destination numbers and on the type of routing option selected by the users. In addition, Simado GBR42 can also be used without a PBX in stand-alone mode by connecting ISDN terminals directly on the NT port.

Intelligent and flexible routing is the forte of the Simado GBR42. 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 specified time. In addition, it allows the flexibility of reserving ports for important users. Numbers received from calling network are converted by Automatic Number Translation (ANT) to match with the destination network.

The Simado GBR42 is very easy to install and operate. Jeeves is a Windows based multi-lingual GUI tool used to configure various parameters. The SIM cards can be accessed after removing its top cover. Antenna mixer (4 to 1) is built-in and hence only single antenna is required. The Simado GBR42 can be mounted on a wall or a table-top.

The Matrix Simado GBR42 (GSM-ISDN Gateway)comes in two variants namely
  1. Simado GBR42-With 4 GSM ports and 2 ISDN BRI Ports
  2. Simado GBR21-With 2 GSM Ports and 1 ISDN BRI ports

 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 with any entry in the Denied Lists. On the other hand, a number is allowed to go through if it matches with any entry of Allowed List. This provides flexibility of allowing only specific numbers while blocking all others.

Automatic Call Distribution
The Simado GBR42 offers different schemes to select destination port for an incoming call. They are First Free and Round Robin.

Call Detail Recording (CDR)
The Simado GBR42 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 GBR42 can be controlled. When the duration of a call exceeds the set time limit, the call is forcefully disconnected. This feature can also be used to release ports that are left open accidentally.

Call Progress Tones
Call Progress Tones like Dial Tone, Ring Back Tone and Busy Tone can be selected to match with the tones used in the region or the country standard where Simado GBR42 is installed.

Caller Line Identification Presentation (CLIP)
The Simado GBR42 supports CLIP on GSM and BRI ports.

CLI Based Routing
The Simado GBR42 can route the call based on the calling party number. This allows routing certain callers to specific ports directly.

Compact and Sturdy
The Simado GBR42 is all-integrated gateway equipment. It can be easily installed on a wall or a table surface.

Day Light Saving
The Real Time Clock (RTC) of the Simado GBR42 moves forward or backward automatically in tune with the Day Light Saving requirements of the country, where it is getting installed.

Emergency Number Dialing
Simado GBR42 allows user to dial emergency numbers for services like Police, Fire Brigade or Ambulance without SIM or without network registering. Maximum 4 emergency numbers can be programmed.

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) Number
International Mobile Equipment Identity (IMEI) number provided on Matrix Simado GBR42 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.

Automatic Number Translation
The Simado GBR42 modifies the incoming number or part thereof so that it matches with the numbering plan of the destination network. The GSM networks require dialing of complete numbers including the area codes. If a caller has dialed just the local number, the Simado GBR42 adds area code as appropriate prefix.

Jeeves
Jeeves is a Windows based GUI software tool for programming the Simado GBR42. It is intuitive, user friendly and supports many languages like English, French, Spanish, German, Russian, Portuguese and Italian.

Least Cost Routing (LCR)
The Simado GBR42 selects a port that is offering the least cost for an outgoing call. It supports LCR algorithms based on Time and Number. Port-wise LCR logic not only differentiates between GSM and BRI ports, but also selects the most cost-effective among GSM ports. Thus, each call can be routed on the most economical route.

LED Indications
Total 8 dual colour LEDs are provided to indicate current status of calls on GSM and BRI ports. Four LEDs-one for each GSM ports and four LEDs showing status of each B-channel of two BRI ports are provided.

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 GBR42 is installed near a state or national border.

PCM-TDM Platform
The Simado GBR42 uses digital switching platform based on PCM-TDM concepts. This architecture provides better speech quality and higher noise immunity.

Port Status
The Simado GBR42 monitors availability of all the ports. If a port is not available for any reason, Simado GBR42 routes the call on the next best-fit port.

Remote Programming
It is possible to change the configuration of the Simado GBR42 from anywhere in the world. System engineer can call on GSM, BRI TE or BRI NT ports and by dialing password he can enter into programming mode to change any configuration.

Returned Calls to Original Caller (RCOC)
The Simado GBR42 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.
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.

Speech Gain
The Simado GBR42 allows user to set receive and transmit 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 channel of BRI ports or even another GSM port. Similarly, a call received on any BRI channel can be placed on a GSM port or even another BRI channel.
