ATEUS ®- STARGATE
ATEUS ®- STARGATE is a compact yet highly sophisticated system. It supports full
remote supervision and configuration via an IP network, or using an external modem over a
BRI-ISDN and analog line, or over a B channel in a PRI-ISDN trunk. The system has been
designed and works with a lot of highly sophisticated functions, which make it fully client-
oriented and highly reliable in cooperation with both GSM networks and ISDN. In addition, it
provides full monitoring and comfortable configuration without functional limitations.
Configuration alterations can be made without resetting, i.e. under full operation. Hot-swappable
plug-in GSM boards, which can be swapped under full operation including SIM cards, are a
matter of course. The use of up to four SIM cards per GSM module in combination with an
intelligent SIM card switching tool and detailed statistics upgrade this system into a powerful
LCR tool. A high product stability is achieved by the fact that the gateway is programmed in the
ASM, i.e. OS-FREE system. Two independent 30MHz Philips microprocessors provide an error-
free operation, high speed, automatic fault detection, and easy upgrade. The system also
features easy installation, simple operation and easy replacement of defective parts - it is
composed of plug-in boards that communicate along system buses independently. As already
mentioned, the system allows for an easy detection of defective parts, automatic locking against
use and easy replacement (hot-swap). Thanks to the above mentioned properties, the system
can be installed and configured successfully within one hour!

1. ATEUS ®- STARGATE Description - General Design
1.1. 19” Subrack
1.1.1. Basic Dimensions
The system is integrated in a 19’’ subrack of the height of 3U and depth of 360mm. The
front side is open, equipped with guides for plug-in boards with front panels – the panel
including a mains switch is part of the subrack. In case not all GSM boards are plugged in, the
free section of the front side must be covered with a fixed panel (fixed panels).
The back side is completely covered with a panel with a built-in ventilator, which is
switched by a thermostat for higher reliability and longer life. An AC mains supply unit is located
in front of the ventilator. The bottom and upper sides are covered with perforated sheet, the
assembly flanges are provided with handrails.
The system bus is designed as a printed circuit board (PCB) with DIN connectors and
fitted to the inner subrack carrier profiles.
1.1.2. Front Side Division
The subrack width is divided into an 8HP-wide mains panel and 19 4HP-wide modules in
the following sequence (from right to left):
• 8HP fixed panel with a mains switch, fuse and mains cable socket;
• 4HP CPU board (must be included in any case);
• 4HP AUX board (must be included in any case);
• 4HP PRI boards (must be included in any case);
• 64HP GSM boards, i.e. 16 times 4HP (1 to 16 boards may be included).
1.2. Available Software for STARGATE
STARGATE program - tool to configure and control STARGATE
STARGATE Accounter - tool for automatic download of cdr info via IP connection
STARGATE Wizard* - utility for easy basic parameter setting
CDR converter - utility for cdr information conversion from text format into CSV format
SIM SN reader - utility for reading of IMSI, SDID numbers of active SIM cards
1.3. Power Supply
1.3.1. Description
The system uses an industrial mains supply unit with primary voltage of 100-240VAC
50/60Hz and secondary voltage of 5V/30A with natural cooling and an auxiliary external
ventilator, which is switched on automatically whenever the power supply temperature exceeds
70°C. The supply is designed with a 30% reserve even under the maximum load.

2. ATEUS ®- STARGATE Description – Main Features
Quick unit start – being free of an operating system (programmed in the processor code),
the system is completely ready to work within 30 seconds following its power on/restarting. Of
course, the full function time of all GSM modules depends on the actual load and capacity of
GSM networks to which the ATEUS - STARGATE is connected.
Intelligent call processing – the ATEUS - STARGATE is fully prepared to route PRI-
ISDN outgoing calls into GSM networks and vice versa. A fully intelligent LCR (Least Cost
Routing) function is the basic tool, allowing to route outgoing ISDN calls to GSM networks both
by the called number prefix, and current date and time and GSM module load in the particular
group. Functions taken over from dialers, which enable to replace a part or whole of the dialed
number with another number, are a matter of course. Calls incoming from GSM networks can
be ignored (the calling party hears the ringing tone), fully rejected (the calling party gets the
busy tone), or received. In the last-named case, the DTMF dialing in combination with voice
messages, or direct connection to the operator(s) can be selected. Using the ATEUS -
STARGATE R.C.U. (see later), you can get a highly powerful routing tool, which contains so-
called blacklist charts – barred numbers - and practically unlimited routing charts. This
combination is extremely useful for installation sites with the so-called full telephone number
carryover where a plenty of numbers come into being whose prefixes do not match the official
prefixes of providers.
Selection of GSM module use – the ATEUS - STARGATE allows you to select one of
three available ways of GSM module occupation: 1. Any outgoing call is set up via a GSM
module according to the B channel used. This option helps transfer routing functions to a
connected PBX router. 2. This mode allows to occupy GSM modules in groups cyclically, and 3.
the last option helps select GSM modules in a group according to the number of minutes called
(the counting mode can be predefined of course).
GSM-network friendly – the ATEUS - STARGATE allows to activate the automatic GSM
module log-out in certain time intervals. Using this function you can log out and disable
automatically unused GSM modules at defined time intervals. Since the time between the GSM
module activation and readiness for work is roughly 10-25 seconds, a user-defined hot reserve
is maintained, i.e. some GSM modules keep logged in. This means that any increase in the
ATEUS – STARGATE load result in an automatic activation of other GSM modules so that the
hot reserve be maintained. This feature also reduces the capacity of the GSM network to detect
a unit and disconnect it from the mains.
High connection rate – since GSM networks are not quite reliable and show lack of
capacity occasionally, the ATEUS - STARGATE is equipped with the automatic call forwarding
to other GSM networks or call rejection (without call loss). This function uses the ISDN signaling
protocol where a call SETUP message is sent to the ATEUS - STARGATE first. This message
contains the called number and CLIP if necessary. Having received this message, the ATEUS –
STARGATE can either:
• reject the call (the other party will route it to another device),
– REJECT message including reasoning (CAUSE), or
• receive and connect the call – SETUP.ACK message.
The device on the other side awaits one of the above mentioned responses for 2 seconds.
During this time, the ATEUS – STARGATE has to decide whether it is able to set up the call,
tries to find a free GSM module and establish connection. If the selected GSM module is busy, it
must find other free GSM modules. If it fails to find a free route, it rejects the call request. The
CAUSE number is user-defined. If it succeeds, it receives and sets up the call.

6
Detailed statistics –provides a detailed overview of the count of incoming and outgoing
calls and their successful connections. The statistic data can be displayed either globally for the
whole ATEUS - STARGATE, or for the selected GSM provider, or the selected GSM module
(SIM card). These data are generated automatically.
Detailed call information – the ATEUS – STARGATE can save information on completed
calls automatically (CDR). Call information includes:
call beginning date and time
call type
I-FD : Not connected incoming call
I-OK : Successfully connected incoming call
O-FD : Unsuccessful outgoing call
O-OK : Successfully connected outgoing call
Relation end reasoning (CAUSE) sent to ISDN interface
Number of B channel used
Number of GSM module used
Number of GSM group used
Connection setup time
Call duration mmm:ss (max. 255:59)
Call cost (if pseudotariff metering is enabled)
Called number
CLIP
SIM card position number
SIM card IMSI or SCID
High number of connected calls – owing to a very short GSM call connecting (routing)
time and intelligent call rerouting in the event of failure, the ATEUS - STARGATE features high
call time per month (traffic volume of over 500,000 minutes/month). The connectivity depends
on the ATEUS - STARGATE configuration and GSM network capacity of course.
SMS receive/send support – the ATEUS - STARGATE helps send and receive SMS in
the PDU format. An intelligent SMS sending over a selected GSM network or module and
automatic announcement of incoming SMS are a matter of course. With the R.C.U. it is possible
to send ATEUS – STARGATE status info SMS.
Up to 8 GSM groups – you can define up to 8 independent SIM card groups in the
system. For example, one GSM group can contain one provider‘s SIM cards.
Up to 32 GSM modules – the ATEUS - STARGATE is a modular system where 1 to 16
GSM boards with two GSM modules each can be installed. The GSM boards are hot-
swappable, i.e. can be replaced easily during operation.
Up to 128 SIM cards – each GSM board contains 8 SIM card holders. However, two SIM
cards are only connected to the GSM modules at one moment. An intelligent SIM card switching
according to time, at random intervals, according to completed minutes or sent SMS enables a
client-oriented approach. A defective SIM card blocking is a matter of course.
Worldwide use – GSM boards are currently available with four different GSM modules.
Ericsson GM22,GM47 and Siemens TC35 modules are suitable for 900MHz and 1800MHz
GSM networks, Ericsson GM48 for 850MHz and 1900MHz.

7
Two antennas per system only – Two receive/transmission antennas can be used in
combination with an antenna splitter (see below) for all of up to 32 GSM modules.
Hot-swappable boards – as mentioned above, all GSM boards are hot-swappable. As a
matter of course, the access to the GSM board can be restricted upon the user‘s request. This
solution provides an easy SIM card replacement during operation.
PRI ISDN interface – is configurable in all available modes, i.e. as Network Termination
(NT), or Terminal Equipment (TE). It can also be set as a Master (synchronization clock) or a
Slave. Using PRI board switches you can easily select RX and TX directions – hence, you can
use a cross-over or not-cross-over cable for the ATEUS - STARGATE <> PBX (Switch)
connection.
Easy control and configuration – The ATEUS - STARGATE can be configured locally or
remotely. To do this, you can employ the following types of connection:
• 2 local RS232 interfaces;
• remote control by an analog or ISDN modem connected to a defined RS232
interface. Automatic ATEUS - STARGATE detection and configuration capacities
make the modem perfectly available.
• remotely via a 10baseT IP interface, using a simple Telnet protocol;
• remotely by the ATEUS - STARGATE RCU* via a 10/100baseT using SSH, SNMP,
HTTP, HTTPS protocols;
• remotely by the in-band B channel in the PRI-ISDN interface**.
No SW is necessary for configuration - the ATEUS - STARGATE communicates through
an RS232 interface and Telnet protocol using standard AT commands. However, high-quality
software running under the Windows OS has been designed for user-friendly control and
configuration.
Fault diagnostics is very simple too – the ATEUS - STARGATE informs of a fault both
visually (by LEDs) and via any interface. A direct display of all processes on ISDN or IP layers is
a matter of course too.
Quality control – you can check the quality of ATEUS - STARGATE calls any time by test
calls (an analog headset connector is available for test calling into GSM networks or ISDN
interface) or by-hearing of one of the two current call directions.
Quick and easy update – since the ATEUS - STARGATE is not bound to any operating
system, any firmware updating is quick and comfortable and is made by the available software.
Updating can be performed locally or remotely and the process is protected against
unintentional disconnection. The updating process takes a few minutes and the existing
configuration is retained.
