Introduction
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 GBR is one such 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 GBR supports flexible and intelligent Least Cost Routing
(LCR) options providing significant cost savings and round-the-clock
connectivity.
Let Matrix SIMADO GBR add a competitive edge to your business by reducing telephone costs!
Matrix SIMADO GBR is a gateway to interface
GSM and ISDN BRI networks. On the GSM side, it supports 2G Quad-Band
operation and 3G Tri-Band operation, allowing it to work with any GSM/3G
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 benefit of
the low-tariff of GSM networks by connecting SIMADO GBR 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 GBR 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 GBR 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 GBR. 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 GBR 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 GBR can be mounted on a wall
or a table-top.

3G Network Support
Matrix SIMADO GBR 3G offers accessibility of 3G
networks for Voice communication. It supports Quad-band for 2G Network
and Tri-band for WCDMA Network. It supports fallback compatibility and
hence offers flexibility to access any available network. Users are
always assured for connectivity using the alternate network in case the
preferred (3G) network signal is weak or unavailable. With 3G power, an
organization experiences Noise-free, Stanch and Crystal Clear Voice
Quality, Enhanced Security and Utmost Coverage.
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 GBR offers different schemes to
select destination port for an incoming call. They are First Free and
Round Robin.
Automatic Number Translation
The SIMADO GBR 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 GBR adds area code as appropriate prefix.
Call Detail Recording (CDR)
The SIMADO GBR 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 GBR
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 GBR is installed.
Caller Line Identification Presentation (CLIP)
The SIMADO GBR supports CLIP on GSM and BRI ports.
CLI Based Routing
The SIMADO GBR can route the call based on the
calling party number. This allows routing certain callers to specific
ports directly.
Compact and Sturdy
The SIMADO GBR 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 GBR
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 GBR 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
Pre-configured 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 GBR 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 GBR. It is intuitive, user friendly and supports
many languages like English, French, Spanish, German, Russian,
Portuguese and Italian
Least Cost Routing (LCR)
The SIMADO GBR 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 color 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 GBR is installed near a state or national border.
PCM-TDM Platform
The SIMADO GBR uses digital switching platform
based on PCM-TDM concepts. This architecture provides better speech
quality and higher noise immunity.
Port Status
The SIMADO GBR monitors availability of all the
ports. If a port is not available for any reason, SIMADO GBR routes the
call on the next best-fit port.
Remote Programming
It is possible to change the configuration of
the SIMADO GBR 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 GBR 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.
Speech Gain
The SIMADO GBR 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.
