8.3.7.4 Network management terminal configuration
8.4 Multi-site and multi network management terminal
8.4.1 PRESENTATION
Our networks can have N independent sites interconnected using IP (Attention, here we are
not talking about ISI protocol interconnection).
Each site has its own SWITCH and the sites are linked together using IP.
Each site has its own primary network management terminal connected using RS232 to the
site SWITCH.
The diagram representing this is shown below:
NeTIS MAINTENANCE GUIDE – Version 1.1
101/139
Fig 1
SWITCHES have a priority n° and the two SWITCHES are always active on the network.
This priority level is broadcast over the identification channel (see §9.3.4.1).
The highest priority SWITCH always manages the network. The others are secondary and
backup.
The interest is that if the link between the two sites is cut, both sites will operate
independently.
This architecture also allows for a remote refresh of the technical and administrative databases
on each site using a basic download.
Example: We modify the SWA-CSA site, we can either refresh the CSB or update the CSBSWB set.
8.4.2 NETWORK SETTING
We are going to parameter the network shown in Fig1.
The network management terminal synopsis will be the same whatever the site.

9. CPUBDT SOFTWARE AUTHENTICATION
(Level 2)
9.1 The authentication network management terminal
The authentication network management terminal is software the purpose of which is to
authenticate equipment manufactured by Etelm using different means of communication.
Without this authentication the equipment cannot operate correctly. It consists in the retrieval
of an encrypted key by the network management terminal software and its transmission to the
equipment on order to unblock it.
There are two authentication methods which are: automatic and manual. One uses internet and
is automatic, the other involves calling Etelm and manually entering the encryption key. Once
the software key is in the software network management terminal, it must be sent to the
equipment to be identified either via a network cable or by a crossed serial cable.
NeTIS MAINTENANCE GUIDE – Version 1.1
107/139
9.2 Use
The Etelm equipment authentication is needed in several situations:
New equipment
Expired validity date
Major upgrade
The authentication procedure only concerns the equipment below.
NeTIS MAINTENANCE GUIDE – Version 1.1
108/139
9.3 Integration
9.3.1 EQUIPMENT
The software is installed on any PC, preferably a laptop, so that it can be used close to the
equipment to be authenticated (especially if a direct connection is to be made). The PC must
have either a serial port or a network port (which is true for the majority of PCs, even older
ones, see images) or, of course, both.
Physical locations of the network and serial ports
9.3.2 SOFTWARE
The authentication network management terminal software is compatible Windows 2000, XP,
Vista and 7. It can be installed in any directory. It contains an executable (which must be
authorised to dialogue on the network by the firewall) and a mandatory library file.
NeTIS MAINTENANCE GUIDE – Version 1.1
109/139
9.4 Presentation
9.4.1 WHY AUTHENTICATED?
The authentication of Etelm equipment is used to protect them from any unauthorised product
copy. The referencing makes it possible to better control the distributed software especially
with regards to quantities, versions, validity periods, sites... which brings special help for
maintenance. To do this each appliance and software must be recognised and identified before
operation becomes possible.
9.4.2 WHAT IS AUTHENTICATED?
Authentication only applies to base stations. Only recent versions are concerned.
9.4.3 WHEN TO AUTHENTICATE?
As explained above, authentication is needed for all new equipment, in order to renew a key
or to carry out a major upgrade.
9.4.4 NEW EQUIPMENT
Equipment can be delivered authenticated or not depending on the case. If an Etelm appliance
has never operated and never been referenced it must be authenticated and unblocked in order
to be fully and correctly operational. To do this the appliance must be installed in its
environment and configured. Next the procedure should be launched using the authentication
network management terminal using the correct settings.
9.4.5 VALIDITY PERIOD
Etelm An installed Etelm appliance which is operational and referenced has an associated
validity date key. When the date expires the equipment is blocked. The equipment must be reauthenticated in order to be used again. To do this, run the procedure as if new equipment
were being installed after having contacted Etelm to extend the expiry date.
9.4.6 UPGRADE
When an upgrade is available its installation invalidates the authentication. A procedure must
therefore be launched from the authentication network management terminal in order to
unblock the equipment again (after the upgrade).

Architecture of phone authentication
As can be seen here, the authentication will be carried out by a technician in the
authentication centre or at the customer site who, in exchange for a first software number
supplied by the equipment to be authenticated, will receive a new number depending on the
unblocking authorisation managed by Etelm.
Compared to Internet authentication the procedure is exactly the same except that the serial
number is supplied orally and not via internet. This liberates from network and router issues.

As above, authentication is carried out by a technician from the authentication centre or the
customer who will use another menu on the authentication network management terminal. It
must be connected to Internet and the equipment at the same time. If this is not possible the
new software key can be retrieved directly from the Internet and the equipment authenticated
using the technique described in the previous paragraph.
9.6 Handling
9.6.1 GENERAL
9.6.1.1 Introduction
The authentication network management terminal is used to authenticate via internet i.e. to
reference and unblock equipment manufactured by Etelm. After having entered the
parameters, either the network management terminal connects to the authentication centre and
downloads a new key to replace the old one, or the new key is entered manually after having
been exchanged for the old key by phone. The network management terminal then sends the
key to the equipment via the network or the RS232 port (serial) depending on the user's
choice.
9.6.1.2 Procedure
When the network management terminal is launched the following window appears. A menu
gives access to a few settings such as the language, help or the choice of the authentication
technique. Clicking on the image either launches automatic authentication (the globe) or
manual authentication (the telephone).
Automatic or manual authentication choice menu
Whatever the previous selection, the following window is displayed (except for what is
outlined in red which only appears for automatic authentication):
NeTIS MAINTENANCE GUIDE – Version 1.1
112/139
Menu to select the communications protocol between the network management terminal and
equipment.
The media used to communicate with the new equipment must be selected. The choice is
made by clicking on the image and validating using OK. Cancel returns to the previous menu.
Next, depending on the automatic or manual authentication choice, a different window
appears.
The "no connection to the equipment" menu specific to automatic authentication is used to
retrieve a new key via internet in exchange for the old key without necessarily being
connected to the equipment. The procedure is divided into several steps.
9.7 Manual authentication (by phone)
9.7.1.1 Network connection to the equipment
This software will therefore make it possible to authenticate equipment by phoning Etelm (or
downloading a key via internet). First the parameters must be configured. To do this, enter the
equipment IP address (which should belong to the same sub-network as the authentication
network management terminal if using a switch or a router...) and the communications port.
NeTIS MAINTENANCE GUIDE – Version 1.1
113/139
To finish click on the "connect" button and the network management terminal attempts to
retrieve the key.
A small window shows the status of events (connection, disconnection and error). The
diagram shows a network management terminal and a BS connected by a cable. The cable is
green when connected and red otherwise. In the following case the connection succeeded (in
the window and the cable is green) and the old key is shown in the "previous key" field.
Typically the authentication network management terminal waits for the new key in order to
send it to the equipment.
In the progress window (at the bottom) there are several items that can be very useful. The
type of software that can be used to make sure there is no error, the version is used to know if
the software is up to date and finally if the equipment is already authenticated. In the example
below a TETRA version 2.0j switch has already been authenticated.

114/139
In the following case the connection attempt has failed because the equipment has not
responded at address 192.168.1.253:
Connection failed
Once the old software key has been obtained either:
Communicate it (with the corresponding customer identifiers) by phone to the
authentication centre (Etelm) which will supply a new key corresponding to the
customer's remaining credit.
Or send it via the automatic authentication menu without connecting to the equipment
(with the supplied customer identifiers).
NeTIS MAINTENANCE GUIDE – Version 1.1
115/139
Enter the new key
NeTIS MAINTENANCE GUIDE – Version 1.1
116/139
Confirm success
Once the new key is entered (red circle figure 8), validate, and the network management
terminal automatically disconnects. To check its success just test the equipment functions,
look at the programme return in the window (red circle figure 9) or check the 'ACT' LED on
the equipment. The LED should flash slowly (frequency of 2 or 4 seconds).
NeTIS MAINTENANCE GUIDE – Version 1.1
117/139
9.7.2 SERIAL EQUIPMENT CONNECTION
The use of a serial cable instead of a network cable does not change the procedure, it is
strictly identical. Parameter configuration changes only.
Manual authentication using a serial cable
As a parameter there is the communication speed and port number to be defined. It is
preferable to leave the default configuration. If the connection fails it is possible to try again
using another communications port.
NeTIS MAINTENANCE GUIDE – Version 1.1
118/139
9.8 Automatic authentication (via Internet)
9.8.1 NETWORK CONNECTION TO THE EQUIPMENT
The software will make it possible to authenticate equipment automatically via internet. First
the parameters must be configured. To do this enter the IP address on the authentication
centre and the communications port (choose any one that your firewall authorises). If a router
is used it must be configured to accept the TCP protocol on the appropriate port.
Next the connection to the equipment should be configured. To do this, enter the equipment
IP address (which should belong to the same sub-network as the authentication network
management terminal if using a switch or a router...) and the communications port.
To finish enter the login and password supplied with the equipment and click on the "OK"
button. The network management terminal connects to the centre and retrieves a valid key (if
the customer credit is sufficient) and sends it to the equipment.
Automatic authentication using a network cable
At the end of the operation the network management terminal disconnects from the centre and
the equipment should be tested to see whether the authentication was successful.
9.8.2 MULTIPLE AUTHENTICATIONS (IP NETWORK)
It is possible to authenticate several appliances one after the other automatically without
changing the configuration each time. To do this all the equipment must be on the same IP
network and the network management terminal must have internet access.
NeTIS MAINTENANCE GUIDE – Version 1.1
119/139
To begin with, create a text file (for example right click on the desktop, new menu, text file)
containing all the IP addresses of the equipment to be authenticated as follows:
IP address entry
The IP addresses must be entered correctly and separated by carriage returns. The file is saved
and closed.
NeTIS MAINTENANCE GUIDE – Version 1.1
120/139
Multiple authentications by IP network
To authenticate several appliances connected to the same network, first check the
"authenticate several appliances on the same network" box (surrounded in red, N°1), next
click on the button showing a file in the window that has appeared (surrounded in red N° 2),
select the text file containing the IP addresses (in red N°3) and finally click on the open
button (in red N° 4).
The addresses appear in the "IP addresses of equipment to authenticate" window as shown
below. If an address is not shown, it is because it is not correct.
NeTIS MAINTENANCE GUIDE – Version 1.1
121/139
IP address validation
Validate click on the OK button. Finally, to launch the procedure, carry on as if authenticating
a single appliance. The procedure is exactly the same.
9.8.3 SERIAL EQUIPMENT CONNECTION
The use of a serial cable instead of a network cable does not change the procedure, it is
strictly identical. The parameter configuration changes only.
NeTIS MAINTENANCE GUIDE – Version 1.1
122/139
Automatic authentication using a serial cable
As for manual authentication, here the communications speed is set and the same steps as
above are carried out. Multiple authentications are not possible because it would need a serial
cable connection to all the BSs at the same time.
NeTIS MAINTENANCE GUIDE – Version 1.1
123/139
9.8.4 NO CONNECTION TO THE EQUIPMENT
It is possible to authenticate equipment via Internet without being directly connected to them.
In this case start by retrieving the old key using the method in the previous paragraph (see
§4.2), send it via internet as explained below, then retrieve the new key and send it to the
equipment using the previous method again.
Automatic authentication without connecting to the equipment
First enter the old key, enter the identifiers that were supplied and click on OK. The new key
will appear. It must then be sent to the equipment.
9.8.5 DIAGNOSING AN AUTHENTICATION PROBLEM ON A NETIS-B
Using the TETRA network management terminal you can see whether a BS is authenticated
NeTIS MAINTENANCE GUIDE – Version 1.1
124/139
In the monitoring you will see a red cross appear on the green background of the icon as
shown below if the NeTIS-B has not been authenticated:

10. PABX GATEWAY
10.1 Introduction
The TETRA IP Gateway for PBX (phone switchboard) is used to open up a classic phone
installation to the TETRA IP radio world.

GATEWAY IP TETRA
Link T2, T0, S0,
This gateway is used to interconnect a phone link to any location of an ETELM IP TETRA
network having the TETRA UDP phone and signalling from the different TETRA
SWITCHES.
This IP / PABX Gateway, in the case of a "full IP" TETRA network with several switches
each having phone access, makes it possible to route phone calls from anywhere on the
network to the TETRA SWITCH managing the network at time t, without using external inter
PABX links.
And on the opposite, for a radio call to a phone, the TETRA SWITCH routes the call to the IP
Gateway corresponding to the phone call.
Communications from phone sets connected to the PABX are sampled, converted to binary
data using MIC decoding (modulation by impulse coding), then encapsulated in IP packets by
the TETRA IP Gateway for PABX.
On the other hand, radio calls are sent to the TETRA IP Gateway for PABX which routes
them to the PABX and, when the connection is made transforms the TETRA UDP IP phone
blocks onto the MIC blocks needed for the phone link.
NeTIS MAINTENANCE GUIDE – Version 1.1
127/139
10.2 Equipment

11.10 Power amplifier (PA)
This module amplifiers the RF signals sent by the CPU module in order to deliver 10 Watts
RF.
It is powered by +28 volts and can be checked on the front face of the UCM2. The PA alarms
are present on the front face of the UCM2. The PA provides a set point for the regulation of
its output power.
The amplifier has an internal blocking mechanism if it does not receive the transmission
command from the UCM. No measurements can be made if the BS is not in TETRA
transmission.
The module has an integrated circulator which protects it from accidental load disconnections
and considerably minimises the risks of intermodulation with neighbouring transmitters.
