1 Introduction
coM.sat ISDN Basic is a digital mobile phone adaptor (TA) which uses suitable GSM
modules and SIM cards for voice communications and SMS transmissions. coM.sat
ISDN Basic is connected to the external or internal ISDN (S0) - port of an ISDN
PABX. The coM.sat ISDN Basic mobile phone adaptor can then be accessed from
each extension user. Conversely, each extension connected to the PABX can be
reached from GSM mobile phones at the most favourable mobile phone tariff via the
coM.sat ISDN Basic mobile phone adaptor.
The coM.sat ISDN Basic is assembled in a stable housing and is suitable for
installation on horizontal or vertical surfaces.
coM.sat ISDN Basic is configured comfortably and user-friendly via the coMsat.exe
Windows application. The devices can also be serviced remotely with the aid of this
application. The application can run under Windows 98®, Windows 2000® and
Windows XP® and should run on Windows ME® and Windows Vista® too.
The performance characteristics, functions and interfaces of coM.sat ISDN Basic are
described in this document.
Furthermore, this manual also includes information on installation, use and
diagnostics.
Users are explicitly requested to read the user safety information first.
The manufacturer reserves the right to make technical changes that serve the safety
of the device and improve its operation.

2 User safety information
The following information applies to the coM.sat ISDN Basic. As the cellular engines
used in this device are manufactured by Siemens (TC35i), we explicitly refer to this
company’s respective safety regulations and operating manuals.
2.1 Electrical safety
The coM.sat ISDN Basic works with a nominal supply voltage of about 10 V.
Furthermore, the device is connected to the S0local port of TAs. Therefore no further
precautions are required to protect the user against high voltages from this device.
However, it should be noted that the user must ensure that they discharge any static
charge they may have before working on the device.
2.1.1 Air traffic safety
Use of cellular engines in aircraft can impair their navigation systems and interfere
with the mobile radiophone network. Their use has therefore been forbidden by law.
The coM.sat ISDN Basic must therefore not be used on board aircraft. Breach of
requirement can cause temporary or complete suspension of the cellular engine
services and / or legal steps to be taken against the offenders.
2.2 Environment with explosive materials
The coM.sat ISDN Basic is not approved for use in potentially hazardous
atmospheres. The user is therefore advised not to use the TA close to such areas,
which could be e.g. at petrol stations, in fuel depots, in chemical works or during
blasting. Should this nevertheless be necessary, the user should take steps to
ensure that no risk can occur.
2.3 Road traffic safety
If the devices are used in vehicles that are used in public road traffic, the national
regulations for telephoning in vehicles applicable for the country in which the device
is must be complied with.
2.4 Non-ionising radiation
As in all radio transmission devices, the user should note that it is advisable for
satisfactory use of the devices and safety of the user that the device is only used in
its normal operating position.
2.5 Electronic medical equipment
The operation of radio transmitters, which includes cellular engines, can impair the
function of medical devices that have not been properly shielded. Please ask advice
of your doctor or the manufacturer of the medical device.

coM.sat ISDN Basic

16/01/09 11 coMsat ISDN Basic Manual V2.7.doc
Note Protection Mark according to DIN 34!
2.6 Measures to be taken in case of loss/theft
If the coM.sat ISDN Basic, the cellular engines or the SIM cards used are lost, inform
your network provider immediately to prevent any misuse.
2.7 Transport
The packaging ex works is designed to protect against mechanical damage and
should be stored for any later transports. To avoid moisture condensation, time must
be allowed for the devices to slowly adapt to the ambient temperature (if they have
been stored in an environment with differing temperature) before starting them up.
2.8 Where to install the devices
The devices should be installed so that they are protected against direct sunlight and
heat. This increases both the reliability of the operation of the devices as well as their
service life, as the components used are less thermally stressed.
The devices should also only be used with the power supplies that they are supplied
with or an original spare part.
The cables to the devices should be installed so that they do not cause any physical
risk. Power cables should be installed separate from the signal cables.
The devices should only be installed by adequately trained personnel.
2.9 Damage and repairs
For safety reasons, the device should not be used in case of noticeable damage or if
it has been exposed to moisture.
Repairs to the device should preferably only be carried out by the manufacturer or
their authorised agents. Should this not be possible at any time, the repair must be
carried out by an adequately qualified person, whereby only original parts should be
used.
The device must be disconnected from the voltage supply before each repair.

The connections and significance of the LED’s are labelled to prevent errors.
Before starting up the device, the SIM cards must be inserted into the provided
holders. Two 3V SIM cards are required for full channel availability, but usage with
one SIM card is possible.
To insert the SIM cards in the device, first push in the round yellow button next to the
cardholder with a blunt, thin tool and then remove the cardholder. The SIM card is
then placed in the cardholder and inserted into the card reader together with its
holder. The contact area of the cardholder must be facing the rear of the device.
Attention: When pushing in the card, ensure that it does not fall out of the cardholder
and that the card is correctly inserted in the cardholder guides. The device requires
3V SIM cards for operation!
3.1 Starting up the device
The SIM cards should be inserted into their reader slot first. Then the necessary
cables are connected: Connection to the TC system as NT or TE, a connection to the
PC's USB port on which the coMsat.exe application is installed, and finally the
antenna cables.
Note 1: The GSM modules used in the coM.sat ISDN Basic for communication via
the GSM network operate with an internal voltage of 3V. Therefore, for proper
operation, SIM cards that can still operate with a working voltage of 3V must be used.
All new SIM cards usually fulfil this requirement. If older cards (designed for a voltage
of 5V) are used, the device possibly cannot log into the network - despite input of the
correct PIN - because the SIMs cannot operate correctly at a voltage they weren't
designed for.
Note 2: When looking at the front of the device, the left-hand SIM card is assigned to
channel 1 and the right-hand card to channel 2.
Once it has been installed, the device can be switched on by inserting the power
jack. This is indicated by the green LED which is labelled “Power“.
All the relevant parameters in the device are deleted in the factory before delivering
the coM.sat ISDN Basic,so that it must be set for the individual installation.
Therefore, when installing the TA for the first time, it must be configured using the
coMsat.exe application. To do this, a USB data link must be established between the
coM.sat ISDN Basic and the PC on which the application is installed.

3.2 Installation of the coMsat.exe application
The coMsat.exe Windows® application is used to configure the coM.sat ISDN Basic.
It is copied into a suitable directory on a PC together with two text files:
Figure 5: coMsat.exe Installation
The coMsat.exe application can now be executed from this directory or via a
symbolic link that can be created manually e.g. on the desktop. A free USB port on
the PC is required for operation with the coM.sat ISDN Basic.
coMsat.exe needs a virtual COM port to access the ISDN Basic. To install it, the
current user must have administrator rights and the contents of the FTDI folder must
be stored in a suitable directory. If the ISDN Basic is attached to the PC for the first
time, the Windows® hardware assistant automatically reports a new device. It asks
for the installation files contained in the FTDI folder. After installation is completed, a
new virtual COM port has been added, e.g. COM3. This port must be used in
coMsat.exe.
The virtual device driver is supplied by Future Technology Devices International Ltd.,
the manufacturer of the USB/RS 232 converter used in the ISDN Basic. If another
driver is required, it can be obtained from www.ftdichip.com. The driver for FT232BM
must be used. The following four files in the FDTI distribution must be replaced by
those shipped with the ISDN Basic:
• FTDIBUS.INF
• FTDIPORT.INF
• FTDIUN2K.INI
• FTDIUNIN.INI

3.3 Configuration of the coM.sat ISDN Basic
The coM.sat ISDN Basic is configured with the aid of the coMsat.exe Windows®
application.
After starting the application by double-clicking the application’s icon, the main
application window is opened. Several file cards are displayed which control the
various functions. These are supplemented by the typical Windows® application
menus, such as File, Connection, Configuration, Info, Firmware, Terminal,
Monitor, View, and Help and a symbol bar for quick access to the New, Open,
Save, Login, Logout, Load/Save Configuration, Load Monitor, Load Status and
About commands.
Various function groups are arranged on the file cards so that they form meaningful
units. These are:
• Interface
• ISDN Cfg
• GSM Cfg
• Routing
• Incoming Calls
• Outgoing Calls
• Fax / Data
• Statistics
• Voice
• Unconnected Calls
• Diversion
• Virtual PBX
• Clock
• Channel 1
• Channel 2
• Info
• SMS
• Diversion
• Terminal
• Monitor
Note: The statistics, voice announcement, unconnected calls and diversion functions
are only activated if there is a valid Basic Pro license (see 3.3.15). The virtual PBX
functions are only activated if there is a valid virtual PBX license (see 3.3.12.6).

3.3.1 Interface
Figure 6: Interface
After starting the coMsat.exe application, the connection to the device is made via
the "Interface" tab. Upon clicking the tab marked "Interface" it will come to the
foreground and its contents will become visible.
The PC interface which shall be used for the data link to the coM.sat ISDN Basic is
selected using the "COM port" drop down list box. It is also possible to let the
application choose the port itself, using the "search" button. Should the application be
unable to find a connected coM.sat ISDN Basic, it will issue the message "No device
found!".

Many functions require an authentication of the user. This is done by clicking on the
"Login" button also located on this tab. The authentication is removed by clicking the
"Logout" button. The termination of coMsat.exe automatically removes
authentication. Therefore explicit logout is only required if coMsat.exe remains
connected to the ISDN Basic after the user leaves it.
To prevent unauthorised persons from logging into the TA and altering the
configuration, at least the configuration password should be entered in the
“Password“ box. Each password consists of max. 19 alphanumeric characters. The
various function groups within the coM.sat ISDN Basic coMsat.exe application are
then accessible with differing protection.
Users who do not know either of these passwords can carry out all the unprotected
functions on the device. They connect to the device by calling up “Connection” on
the menu bar and calling up ”Go Online” in the menu that opens, or simply use the
desired function. The applications then connects to the coM.sat ISDN Basic. In this
mode, the device configuration can be read, but not altered. SMS can be sent and
received and any SMS received can also be read. The same procedure applies to
remote access to the device.
However, the configuration settings can only be altered by logging in with a
configuration password. Then all configuration data can be read out, amended and
resaved. The ”Vendor Functions” password makes further functional blocks
accessible, via which the various network operators can be authorised or excluded.
If a password is entered, this password is transferred to the TA together with the
configuration data. The next time the TA is logged into, the password must first be
entered in the relevant box.
A password can be deleted or altered after logging in by deleting the relevant box for
the password or entering another password. The new password is then valid after the
next update of the configuration.
On the interface tab, the user can specify additional actions after successful login.

monitor can be loaded. The first three are activated by default on every execution of
the software.
The firmware name and version (if loaded) and the user configurable device
identification are also displayed on the interface tab. The device identification is
stored in the device on updating its configuration and displayed on the interface tab
after reading the configuration. Its purpose is to allow easy recognition of different
devices in a multi-device installation.
The configuration data of one or several devices can be saved as usual in
Windows®. The files contain the configuration, the firmware ID, the device
information and the monitor contents, if these have been loaded before.
At the bottom of the coMsat.exe window there is a state bar which displays the
