TETRA TACTICAL DIGITAL
MOBILE RADIO SYSTEM
TETRATAC – STT115GENERAL
TETRATAC STT-115 is the SELEX Elsag new
generation digital tactical trunked mobile radio system
complying with TETRA V+D Standard.
Thanks to the wide range of available functions, ser vices
and features, the TETRATAC system can satisfy the
needs of a variety of professional users encompassing
the emergency security services and military applications
such as peacekeeping missions and rapid reaction
actions.
TETRA is a telecommunications standard for Private
Mobile Radio (PMR) systems developed by ETSI
(European Telecommunications Standardisation Institute)
as a European answer to the evolving needs of PMR
Operators that have to cope with traffic congestion and
a growing demand for speech and data services especially
designed for professional communications.
The evolution of digital technology gives a way out of
this situation allowing high spectrum efficiency and
coexistence with present analogue systems.
STT-115 is the SELEX Elsag new generation
rugged digital tactical trunked mobile radio system
complying with TETRA V+D Standard
MAIN FEATURES
• New generation digital tactical trunked mobile radio
system
• Complying with ETSI TETRA Voice+Data Standard
• Provision of advanced network and subscriber ser vices
• Half and full duplex voice, data and video transmission
• Protection with encr yption of all communications
• High reliability due to the capability to implement
meshed topologies
• Fall back operation
• Integration in public ITU-T and militar y EUROCOM and
STANAG standard Networks
• Radio CNR integration (CNRA)
NETWORK ELEMENTS
SWITCH CONTROL NODE
The SCN is the network element that has the highest
capabilities in terms of switching, networking and
database management of mobile subscribers.
It has inter faces to Radio Base Stations, Dispatchers,
management system, and other STT115 switches.
RADIO BASE STATION
The Radio BS is responsible for connecting all terminals
operating inside its own radio coverage area (cell).
During normal operations, the BS is directly
connected to and controlled by the relevant SCN.
Connection with mobile terminals is achieved by radio
coverage that is compliant with the TETRA Standard Air
Inter face Protocol.
SECURITY MANAGEMENT SOFTWARE
This SW kit allows providing the TETRATAC system with
specific security features, like as customized solutions
for Air Inter face Encr yption and End-to-End Encr yption.
Both encr yption algorithms, natively based on ETSI
standards, can be modified on request to Customers’
needs. The SMS package, in its full extension, includes
the AIE and ETE customized algorithms, the relevant
downloading packages to properly set-up the switches
(SCN), the base stations (RBS) and the terminals,
the overall key management system (generation and
distribution facilities).
It must be noted that this kit does not require
dedicated HW platforms; it can therefore be
installed on standard TETRA equipment without HW
modifications or add-on’s.
GATEWAY SWITCH
The GW switch is based on a dedicated TDM switch
capable of connecting Eurocom and STANAG based wide
area systems (WAS). Il also allows for integration with
satellite bearers and Combat Net Radios (CNR). It can
be physically accommodated into the SCN enclosure and
be connected to it through an E1 por t.
DISPATCHER & NMS OPERATOR CONSOLE
TERMINALS
Two kinds of terminals are available in the TETRATAC
System: Por table and Vehicular Terminals.
They both can operate in either Trunked or Direct
Mode, allowing Voice and Data communications both in
Half- and Full-Duplex Mode.
The terminals are standard TETRA terminals;
depending on specific security requirements, they can
accommodate AIE and ETE customized algorithms.
TETRATAC NETWORK
TETRATAC has been conceived to provide mobility to
subscribers of already available Fixed Private Networks.
In par ticular, in the case where the Fixed Network is
compliant with EUROCOM Standard, from the customer
point of view, the system acts as a mobile extension of
the EUROCOM network.
MANAGEMENT SYSTEM & DISPATCHER
TETRA Management System and Dispatcher is a software
application running on Multimedia Data Terminals (MDT)
contained in the Network Control Centre (NCC).
MDT consists of a laptop PC, a voice Phone and optionally
a Dispatcher Audio Console (DAC).
TMS-D functions listed above are classified as “Element
Manager Functions”, according to the terminology adopted
by ITU (TMN M.3010).
The system - when equipped with the GW
switch - provides the requested connectivity with various
inter faces (ISDN PRI, ISDN BRI, STANAG 4206 4212 and
STANAG 5040, STANAG 4290, etc), while the 2Mbits
connection inside SCN provides the possibility to establish
up to 31 concurrent calls between mobile-to-mobile or
mobile-to-fixed users.
The following operational features are suppor ted:
•
•
•
•
CLOSED VIEW
Direct mode amongst terminals
Stand-alone STT115 System
Base Station in fallback mode
STT115 System “1” connected to System “2” in
transparent mode, via SELEX Elsag GW Switch to increase
the covered area (with the two areas near to or
distant from each other maintaining all TETRA ser vices
and Hand-Over capability)
• STT115 System with external connection to other civil
and militar y network and satellite (with GW switch )
TETRATAC System allows mobile subscribers to set up
voice and data, individual and multiple, mobile-to-mobile
and mobile-to-fixed subscriber calls. The term “fixed
subscriber” identifies both a user not equipped with a
TETRA terminal but connected to a TETRATAC System
(via Militar y SELEX Elsag GW switch local connections)
and a user belonging to any network connected to the
TETRATAC System.
VEHICULAR TERMINAL
SYSTEM ARCHITECTURE
The TETRATAC system is composed of:
• One or mode STT115 switches
• One or more Radio BS connected to the STT115-SCN
directly or remotely via WAS network
• A set of por table and vehicular terminals
• One or more gateway switches (option), that can be
fitted into the switching control nodes carr ying cases
