Introduction
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. 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 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-alone
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 2G Quad-Band and 3G Tri-Band operation allowing it to
work with any GSM/3G 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 facilitating selection of 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.

3G Network Support
Matrix SIMADO GFX44 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 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, Least Cost and others.
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 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 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 202A.
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.
Fixed Number Dialing
Preconfigured number can be dialed out as soon
as a call lands on a port. This allows point-to-point connectivity
eliminating the need of dialing the same number repeatedly.
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 supports LCR algorithm based
on dialed number. This features allows selection of the most economical
route for an outgoing call among the available GSM ports
LED Indications
A Dual-color LED is provided for each FXS port.
They indicate current status of calls on these ports. Network and Call
status on GSM Ports, is indicated through the LEDs dedicated LEDs.
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.
Returned Calls to Original Caller (RCOC)
Matrix SIMADO GFX44 maintains records of all
the unsuccessful calls on GSM network due to No Answer and other such
conditions. When such a call is returned, it routes the call to the
original caller.
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.
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
SIMADO GFX44 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.
