Tactical Data Links Evolution - are we forgetting
something -

• simple solutions often come out of necessity
  i.e. frequently damaged F/O cables
• P3 provide tactical data/voice links over copper
  cables up to 20Mbs over 5Kms
• Simple and effective alternative to fibre-optics
  - without loss of functionality

Why Go Back to Copper? Simple, cheap, effective
and soldier friendly - no functionality loss
Ideal for rapidly deployed Tactical LAN links
Up to 20Mbs bandwidth over 5Kms hot backup when
using 2 or more channels Common IP interfaces
for varied applications video, encryption,
D/A Sensors, etc. stand alone operation
(battery to 8hrs) Field Telephone over the same
copper link - works even when the data link is
down VoIP - Network wide reach via IP
addresses Variety of power sources (AC, DC,
internal rechargable battery, generator, fuel
cells etc.

• Current Practice in Tactical LAN Deployment is
  to use Fibre-Optic Based Products
• Fibre is easily damaged and is impractical to
  repair in the field, bulky to store/transport
• Copper cables are simple soldier friendly
  easy to roll out, retrieve. It is cheap and can
  be fixed as easy as tying shoelaces!
• RADSL Technology allows fast transmission (up
  to 8 Mbs) over long distances of 3..7Kms
• P3/P1 are designed to overcome the fibre
  problem - using off the shelf technology - with
  useful features - without loss of functionality

All units use SDSS, as their statutory record.
FLMS is their fallback network database. FLMS
transactions are applied to SDSS when
communications are regained.

Typical Configurations
Extending data link further

broadcasting data links to different locations-
remote P3 channels are all set to Tx-Low- unique
IP addresses must be set for VoIP Telnet
management

Australian Defence School Of Signals - Setup

• unique IP addresses for all P3s
• Spanning Tree (ring protection) must be
  enabled on all P3s and takes approx 30 sec
  to learn the P3 network
• 3rd P3 transmission channel could be used to
  further extend the network (e.g. to a P1 or
  another P3)

P3 Artillery Fire ControlBallistics Computer
Voice and Data Links the Gun Battery
Data Terminal (PC) - P3 provides Ethernet
voice extension over copper - 2 spare channels
are available for further voice/data links
Optional WD1T link for redundancy
P3 provide simple and effective distribution of
data for fire solution systems on the existing
DON10 links used for voice commands (e.g. TANOY).

• Data transfer example using COTS
• P3 provides transparent Ethernet over copper
  to all remote P3s
• using the NetMeeting application individual
  links are established by calling remote P3
  IP address
• spare channels can be used for links to other
  P3s or for redundancy

Examples of Industrial and Defence Applications

• Tunnels or Underground Data/Voice Extensions
• fire-proof telemetry
• air-quality monitoring
• fan activation
• alarm activation
• emergency voice channels
• gas, electricity conduits
• Oil pipelines
• Video/Audio Surveillance
• (SCADA Upgrades)
