| Functie.
De VTU Deployable gedraagt zich als een volledig onafhankelijk
netwerk en dient als voice server in een noodsituatie. Het
voorziet in een aansluiting met de buitenwereld via een sateliet
uplink, en het gedraagt zich als een volledig functioneel
bereikbaar systeem naar een HQ voorziening. De VTU Deployable
laat communicaties toe in volledig verwoeste gebieden, zowel
door mens als natuur. U kan dit toestel ook inschakelen bij
grote netwerkproblemen. Het basis platform voorziet in een
beveiligde IP (Internet Protocol) verbinding op de EDU; het
zorgt voor beveiligde draadloze telefoons voor gemobiliseerden
of voor team leden in noodsituaties, of voor beveiligde IP
lijnen via Satelite RF of andere land gebaseerde verbindingen.

Hoe het werkt.
De VTU Deployment wordt opgestelt met het technische team
ter plaatse. De IP-sat uplink, en de andere protocols nodig
om de connectie met het hoofdkwartier te verkrijgen, worden
ingezet. Er worden 2 IP hardwides telefoons geïnstalleerd
die de taak overnemen van de basis, terwijl de andere gebruikers
IP Softphones kunnen gebruiken via hun laptops en dit binnen
een volledig beveiligd draadloze voice en data communicatie
systeem. Op deze manier kan er gebruik gemaakt worden van
alle mogelijke toepassingen zoals voice mail, het doorverbinden
van telefoons en conference calls.

Voordeel van de technologie
The VTU Deployable basic platform offers enormous scalability. Therefore,
VTU Deployable communication solutions can be tailored (adapted/scaled)
to meet specific local and wide area communication infrastructure
requirements. They are designed to connect to commercial or military
communication networks with a wide range of interfaces and data
rates. The VTU Deployable can be tailored to provide any traditional
data transport that may be desired. Where end-to-end quality of
service is required for time-critical applications (such as voice,
video and transactional applications), bandwidth can be dynamically
allocated across the wide area using satellite uplink or traditional
ground-based transport via IP, T1/E1, analog, digital, Frame Relay
or Asynchronous Transfer Mode (ATM) via the VTU WAN Access.
