TetraFlex 7.5 Manual - IP Backbone network layout and
configuration
All interfaces in the router network that must be able to join in a multicast group must have
IGMP and PIM-SM enabled.
2.16.10.2.2.1
Multicast and VPN
As such – VPN/IPSec does not support the transport of multicast packets. GRE tunneling
does support multicast routing – but is not encrypted. Therefore the configuration shown at
end of this document – the recommended configuration – uses IPSec encrypted GRE
tunnels. Combining the IPSec and GRE will ensure the routing of both unicast and multicast –
and still maintaining integrity and intrusion security of the network.
2.16.10.2.2.2
GRE tunneling
Generic Routing Encapsulation (GRE) is a tunneling protocol designed to encapsulate a wide
variety of network layer packets inside IP tunneling packets. The original packet is the
payload for the final packet. GRE was developed by Cisco and was designed to be stateless;
the tunnel end-points do not monitor the state or availability of other tunnel end-points. GRE
creates a virtual point-to-point link with routers at remote points on an IP internetwork.
2.16.11
Applicable tools for router programming
The Cisco offers a CLI – Command Line Interface. This is accessible through the console
port of the router. Use the blue cable delivered with the router. In this case use the serial port
of your PC. You can use any of a variety of terminal emulation programs.
If you know the IP address of one of the Ethernet ports on the router – you can also telnet
into the router and use the same CLI.
The configuration of any Cisco router – can be exported from the router and onto a so called
TFTP server. The router configuration file is then an ASCII formatted text string. This can be
opened – edited and saved by the use of any of a variety of text editor programs.
After editing – the file can be re-imported to the Cisco router. After a reload of the router – it
will reflect the newly introduced configuration changes that you made offline.
2.16.11.1 Ultraedit:
o A text editor program for offline editing of configuration files.
2.16.11.2 WordPad:
o A text editor program for offline editing of configuration files. Available typically in
Windows.
2.16.11.3 HyperTerminal:
o A Windows standard program that can do both serial communication and also
use TCP/IP to connect to router via Ethernet.
2.16.11.4 Putty:
o A very versatile program that does serial and IP connections.

TETRAFLEX V7.5 MANUAL - General system description
3.1 GENERAL SYSTEM DESCRIPTION
3.1.1 TetraFlex V7.5 General System description
For complete system description, refer to ref.1: “TetraFlex v7.5 System description.pdf
3.1.2 Site versus Node:
Until the DAMM TetraFlex® system software was introduced we have used the word “Site” to
indicate how many radio sites there were in a system. There was coherency between number
of “Sites” and number of “Radio sites”.
The DAMM TetraFlex® concept opens for “Sites” meaning the actual geographical position of
the equipment and a NODE meaning any unit running a BSC.exe application (except for the
redundant BSC).
A node could be a radio node, GW node or a combination of these.
3.1.3 Software packages:
All DAMM TetraFlex® system software packages with all Functions and Applications are
available on http://www.damm.dk/ restricted area in encrypted form for a period of minimum
18 months after Release Date
o All Software Releases consist of:
o Software package with Software Release number.
o Release Note.
o Commercial Note.
o A software package can be de-encrypted by means of any valid DAMM dongle.
o If a new Software Release contains bug fixes, which have a serious effect on the
operation of a system, the Application Date can be set to an earlier date, and
thereby allow execution on systems, where the dongle Application Date Limit has
expired. DAMM Support Department is responsible for keeping the www.damm.dk
restricted area updated
o Software packages with a Release Date older than 18 months shall be removed
from www.damm.dk
3.1.3.1 Software packages execution or update:
The dongle controls which software release and which part of the release that can be
executed on the BSC4XX or PC in which the dongle is inserted.
The customer may decide to execute the total package or only some of the files in the
package.

TETRAFLEX V7.5 MANUAL - Base Station Controller
3.2 BASE STATION CONTROLLER
3.2.1 BSC.exe description
The core software for the TetraFlex® system is the Node Software (BSC.exe) running as a
service under Windows XP or Windows 7. It can run on both the BSC421 and BSC412 Base
Station Controllers (and on an ordinary PC or Server as well), and adapts automatically to the
detected hardware platform. The BSC.exe service contains all the functions needed to run a
complete Tetra system, including Subscriber Register with Security Key Register, Radio Cell,
Voice Gateway, Packet Data Gateway (extern connection) / Server (Tetra-Tetra connection)
and Application gateway.
The software supports the use of Redundant Base Station Controllers, as one BSC will be
active and the other BSC standby. Communication and supervisory between the two BSC’s
will ensure, that the standby BSC automatically takes over, if the active BSC fails.
3.2.2 BSC-GUI
The user interface for the BSC.exe from version 7.5:

TETRAFLEX V7.5 MANUAL - Base Station Controller
The BSC-GUI can be started from the TetraFlex Start menu or the Taskbar. The GUI can
only operate on the BSC.exe that is running on the same node.
The GUI has 7 tabs (8 for the BS41x version):
Status: (se figure 3-1) gives an overview of the status of the BSC, TR (Transceivers) and PS
(Power Supply’s). It is possible to clear alarm, access the OM command system, Activate
BSC and BS (Only BS41x), Restart and Stop the BSC, and Update of software and Restore
and Backup of software and settings. These are functions also available in Network
Management.
Console: The Console window is updated at each BSC start-up, and shows the start-up
status of the system. The window is dynamic and will be updated when the status of the BSC
changes e.g. from active to inactive
The Clear Button deletes the actual content of the console window.

The TetraFlex® Network Management (NM) application is a graphical interface to the
TetraOM application (OM). This indicates that most of the functions in the NM may as well be
executed in the OM using the appropriate OM command
The Network Management (NM) software may be executed on any PC which has an IP
connection to the infrastructure. The NM must be able to listen to the multicast which means
that the PC must be connected to the LAN

below this level, it leaves the node again without any deregister signaling, and it
goes into scanning and checks for a node with better signal.
o Access - Radio access parameter -53dBm to -23dBm. This, to reduce the MS
output power depending on how close it is to the radio node. The ETSI defines it like
this: P = MIN ( MS_TXPWR_MAX_CELL, ACCESS_PARAMETER - RSSI )
o This means that a) the MS never chooses an output power above
MS_TXPWR_MAX and b) the output power depends on the downlink signal strength
RSSI in combination with ACCESS_PARAMETER. The idea is simple: If the MS is
close to the BS, it can reduce its output power. ACCESS_PARAMETER defines how
much it can reduce it.
Example: MS_TX PWR = 30dBm, ACCESS = -30dBm
MS is far away from the radio cell, RSSI=-105dBm.
P=MIN(30dBm, -30Bm-(-105dBm) = MIN(30dBm, 75dBm) = 30dBm MS transmits
full power.
MS is very close to BS, RSSI=-55dBm.
P=MIN(30dBm, -30Bm-(-55dBm) = MIN(30dBm, 25dBm) = 25dBm MS transmits
with reduced power.
The value of -53dBm maximizes the effect of power reduction:
P=MIN(30dBm, -53Bm-(-55dBm) = MIN(30dBm, 2dBm) = 2dBm MS transmits with
very reduced power.
The value of -23dBm minimizes the effect of power reduction:
P=MIN(30dBm, -23Bm-(-55dBm) = MIN(30dBm, 32dBm) = 30dBm No power
reduction yet.
o RDT - Radio Downlink Timeout: This it is a measurement of the downlink quality.
The higher the RDT value is, the longer the MS stays on a channel with bad quality.
Factory setting middle value (1152TS).
SRT - Slow Reselect Threshold above fast (Factory setting 10dB)
FRT - Fast Reselect Threshold (Factory setting 12dB)
SRH - Slow Reselect Hysteresis (Factory setting 10dB)
FRH - Fast Reselect Hysteresis (Factory setting 10dB)
The parameters SRT,FRT,SRH and FRH are for network planning and are defining the
behavior of MS cell reselection in a multi node system. The parameters are explained in
details in the ETSI EN 300 392-2 is chapt. 18.3.4.4 ”Ranking of neighbour cells” And
18.3.4.5.x “Criteria used during cell reselection”:
Unless there is trouble with MS cell reselection the factory settings should not be changed.
o Sub. Class - Subscriber Class (Class 1-16 , default all class present).These
parameters can be programmed in the MS to match the bit pattern of a radio cell to
obtain a preferred radio cell to connect to.

Bit 1 and 2 are signaling "highly preferred", 3 and 4 are signaling "preferred", rest
is "normal". Having all 16 bits set will allow any MS to attempt registration.
The purpose is to have MS registering only with radio cells with matching
subscriber classes. I.e. a MS with class 16 - will only try to register with a cell
supporting class 16. If a MS has class 2 and class 16 it will prefer a cell with
class 2 support before looking at cells with class 16 support.
A MS has a subscriber class programmed. If in the profile setup "MS controlled"
is selected, it is the MS's programming that decides about which nodes the
terminals will try to attach to.
If defined in the profile, the MS will receive notification from the node about a
new set of subscriber classes to work with.
If defined in the profile, the shown options apply
o Call dialing
Determines whether calls uses the SSI programmed into the terminals or may
use either SSI or user numbers defined in the subscriber register.
o Use SSI for group call
This is a definition which is applicable only to the displayed information.
The function is implemented to circumnavigate differences in the way certain
brands of terminals displays the group information, for an instance Motorola

3.3.5.4.4 Dial-in subscriber
The dial in SSI is an internal number used to access groups through the Voice gateway and
to show an identity for the group users.
E.g.: A user with Dial-IN SSI 99 makes a PABX dial in to Group 1700003:
Dial 700000
Dial 1700003
Dial 99
Damm PABX (Answering machine)
Damm group 3 (Answering machine)
Dial-In number
Now the PABX user can make PPT or Voice detect group call and is identified as “99” on the
Tetra terminals.
PIN Code – If using a PIN code the Dial-In user is prompted from the Answering machine to
enter the PIN-code before he can make the group call.
The PIN-Code options are:
○ Barred – Now Dial-In is allowed
○ Disabled – The use of PIN Code is disabled no PIN code is needed.
○
The PIN code can be from 1 to 999999999

3.4 AUTHENTICATION AND ENCRYPTION
3.4.1 Description
This section describes in detail the function of the Security Key Set used for authentication
and encryption.
Only the method is described, for further information regarding the Subscriber Register, BSC,
distribution of subscriber data etc. please consult the relevant manual sections.
3.4.2 Definitions
Dongle Key
K1
Security set
The key value file generated by the terminal programmer. File is in plain
text and contains key value associated to TEI
The secret key programmed in the Node Dongle. The Dongle Key is
enabling the key register in the subscriber register
The Security Keys derived from the K file and placed in the key register
The distributed key sets. Should be updated at regular intervals
3.4.3 Description
The key file produced by the terminal programmer (K) is read in to the system and is
encrypted using the Dongle Key and placed in a key register (K1).
This key register is now “protected” by the dongle key.
This means that if the key register is moved to another node, the Dongle key must be moved
as well.
The content of the key register (K1), decrypted with the dongle Key, and the TEI or SIM
reference value is used to produce a security set (Derived keys) which is placed in the Master
Subscriber Register and distributed to the Subscriber Register on the other nodes as SSI +
Security Set. After this the TEI / SIM reference is essentially no longer used.
When updating the Security Set, the K1 key and the SSI is used to generate a new distributed
Security Set.

TETRAFLEX V7.5 MANUAL - Authentication and Encryption
Figure 3-32: Key principles
3.4.4 Backup
It is essential that the K values are kept at a safe place that means to place the programmer
key file in a safe place.
Backup should always consist of at least:


Master Subscriber Register
Key Register
3.4.5 Restore
If the node containing the Master Subscriber register is isolated or removed, the system will
continue to work as usual except that new terminals cannot be added to the Subscriber
register.
When using encryption/Authentication it is recommended to wait adding subscribers until the
node containing the Master Subscriber Register is available again.
Alternatively it is possible to assign another node as Master Subscriber register and add the
subscribers to this register.
After adding subscribers, the Key File (K) is read into the Subscriber Register as described
previously.
This will create a new Key Register on this node containing the K 1 values for the new
terminals.
The disadvantage of this is that when the Security Sets must be updated, both nodes must
be updated, so this method is NOT recommended
In case the node containing the Master Subscriber Register is totally lost or an exchange or
change of node for some other reason is preferred, then all Key Files (K) can be read in

TETRAFLEX V7.5 MANUAL - Dispatcher
3.5 DISPATCHER
3.5.1 General Description
The Core of the Dispatcher is the TetraFlexApi.dll. It contains all the core elements to be able
to connect an Application to the TetraFlex® system. As standard, the TetraFlexApi.dll is
delivered with a GUI (Graphical User Interface). This provides the complete Dispatcher
Application.
The TetraFlexApi.dll contains a fully documented API (Application Programming Interface)
TetraFlexApi.h file which allows the DAMM supplied GUI to be replaced with other GUI
applications provided from third party vendors. Thereby applications with other features and
in other languages are very easily implemented without any need to touch the core interface
to the system.
The TetraFlexApi.dll is delivered with a DAMM License Dongle to permit the use.
DAMM dispatcher from V7.30 and ahead requires a dispatcher entry in the dongle to be able
to start. Dispatcher from V7.40 and ahead requires a Microsoft .NET Framework and MS
SQL Compact database to be installed. This is valid for the DAMM dispatcher only, not for
any third party application.
The TetraFlexApi.dll is intended to be used on a Windows XP or Windows 7 platforms.
Any Node (Base Station, Gateway node etc.) of the TetraFlex® system can have an
Application Gateway activated, and each gateway can handle several simultaneous
application connections. The connection from the application to the system is done with
standard IP protocols (TCP/UDP) to the external (WAN) side of the node, and the application
can be located anywhere provided a standard IP connection to the node’s external WAN side
is possible.
The TetraFlexApi.dll configuration includes a list with one or several IP addresses of
Application Gateways. The TetraFlexApi.dll will scan through the list and try to register with
the first IP on the list, if found the scan is stopped, otherwise an attempt to register with the
next IP entry in the list is made (like a mobile scanning through its frequency list). The
registration occupies an SSI position. A PIN-code Authentication is added to prevent other
applications to register with same SSI. This allows redundant gateway connections and
allows the application to be moved to new locations without any reconfiguration.
The TetraFlexApi.dll supports a.o. to display the DAMM Dispatcher Phonebook with all
subscribers belonging to its own Home Organization and all Associated Organizations.
The phone book is an extract from the TetraFlex® subscriber register which is automatically
uploaded to the dispatcher using its own dedicated multicast address. This means that the
home organization subscriber register can be maintained from the dispatcher provided
access has been granted in the subscriber register.
Dispatcher functions include Individual-, Group- and Broadcast calls, monitoring of all active
calls including individual simplex and duplex calls, sending and receiving SDS, adding DGNA
groups, performing discreet and ambience listening etc. Additional features are planned to be
added in coming releases. For further information regarding future features, see the Feature

The TetraFlexApi.dll will at registration check for correct protocol version. When the
TetraFlex® system software is updated with new features on the Application Gateway, the
TetraFlexApi.dll will also be updated and shall be installed at the GUI applications.
The TetraFlexApi.dll will be fully backward compatible, which means that older GUI
applications can use a newer version of TetraFlexApi.dll.
3.5.2 TetraFlex® Dispatcher Functionality
The Dispatcher application is developed to run on a Windows XP or Win7 platform. To launch
the Dispatcher application the following things are required:





IP connectivity to an Application GW on the IP backbone network.
Hardware dongle with API client and DAMM dispatcher enabled.
A valid Dispatcher SSI and user number defined in the subscriber register
A valid PIN code (optional) defined in the subscriber register
Organization 0 (Zero) defined in the subscriber register, also if this is organization is
not in use

○ Google map – Standard Google maps. These are like the maps you get when
accessing http://maps.google.com/ and off course this requires an internet connection
to access.
○ Google map premier – Uses Google maps, but with a more advanced interface to be
able to show e.g. RSSI measurement and lines between the position history points on
the map. It is possible to cache Google maps to speed up the changing of the maps or
zoom in and out on a map. If the Internet connection is broken it is possible to use the
cached maps, but with the limitation that areas and zoom levels that are not cached,
will not be shown. The cache folder is used to define where the cached maps are
stored to and retrieved from. It is possible to get a premium Google account that
makes it possible to get faster updates of the maps and without limitations of how
many maps it is possible to collect. If you have a Google maps Premier license, Login
information can be added in the client Id and Key fields. It is possible to add layers on
top of these maps in ESRI shape format.
○ Open Street maps – Free geographic data. It is possible to show e.g. RSSI
measurement and lines between the position history points on the map. It is possible
to add layers on top of these maps in ESRI shape format*. The cache folder is used
to define where the cached maps are stored and retrieved from.
○ Raster maps* – This map format makes it possible to make your own map in GEO
TIFF or ERDAS ECW format. In the Path field you can select the directory where the
GEO Tiff or ERDAS ECW files are placed. If selecting a map in one of these formats
the Units and Projection** fields will automatically be filled in if the map file is
provided with this information. If the projection information is not provided in the map
file it can be typed in manually. If the projection -or units parameters are not correct
you will either get a warning or the map will not be shown correct.

3.5.5 Call Authorized by Dispatcher (CAD)
This service is configured in the subscriber register profile and allows the dispatcher to verify
call requests before calls are allowed to proceed. This is a useful service to utilize when radio
user discipline needs to be maintained. This service also reduces the amount of radio traffic
on a network as only essential work related calls are permitted. However, the frequent need
for all communication between terminal users and the time delay experienced in authorizing
calls may make this service unacceptable for some user organizations.
