RUDICS Circuit Switched Data

• RUDICS - Router based Unstructured Digital Inter-Working Connectivity Solution• Mobile Originated [MO] and Mobile Terminated [MT] 2400 bps circuit switched data

connectivity for integrated data applications• Key Benefits:

– Provides global MO and MT capability– Gateway interface provides virtual modem ports that can be routed using terrestrial data

connections– Interface is similar to Telnet with AT Commands and “Connect”, “Busy” etc. messages

Iridium – A Unique DOD Value

Testimonials

• “In this fast paced war, if a communications system was not functioning quickly, alternative methods were employed…The only systems consistently praised by the Marines were the Blue Force Tracker (SATCOM- though unsecure) and Iridium Phones (SATCOM). These systems provided reliable communications at all times. In many instances these systems were the sole means of communication.” Marine Corps Systems Command Liaison Team, Central Iraq, May 2003

• Iridium handheld satellite telephones with secure sleeves also proved to be invaluable for diverse SOF units conducting split operations in the rugged mountainous terrain. SOF liaison teams carried Iridium units during all operations with the Northern Alliance. Brig. Gen. (P) James W. Parker, USA, Director, Center for Intelligence and Information Operations, SOCOM. (Signal Magazine, March 2003)

• The Iridium phones were a key communications tool during the Afghanistan war, and since then thousands of phones have been distributed to unit commanders and special operations forces. Over all, communications traffic on all Department of Defense networks has gone up over five fold since September 11, 2001. (http://www.strategypage.com/iraqlessonslearned)

• While headquarters could set up a satellite dish and establish a local Internet network, people in vehicles or running around on foot needed an Iridium satellite phone or BFT to be sure of always getting through. (http://www.strategypage.com/iraqlessonslearned)

Iridium – A Unique DOD Value

Testimonials"Only RELIABLE Communications out of the Valley (During OPERATION ANACONDA)"

"CA Units lack organic over-the-horizon communications... (EMSS) ability to directly access host nation personnel, relief organizations, and higher headquarters via commercial telephone networks, regardless of the (EMSS) user's location is invaluable." US Army Civil Affairs

"Without (EMSS) we would have been unable to support the Air Mission in Afghanistan" USAF

"A unit could not establish communications with fire support unit using tactical communications...fire mission was successfully completed using (EMSS) handsets." SPECOPS

"Instrumental in augmenting tactical communication support. At times, due to the limitations of tactical equipment not being able to operate on the move (i.e. SMART-T, UHF TACSAT, and HF), EMSS phones...were the only available means of communications until units stopped and had the time to set up their tactical communications equipment." 1st MARINE DIVISION

"(EMSS) is particularly effective for units during Operational Preparation of the Battlespace (OPB) missions when the use of tactical communications is not prudent." SPECOPS

"EMSS equipment provided supply/logistics convoys with over-the-horizon communications capability." (Solution developed after ambush of supply convoy that didn't have over-the-horizon communications capability, resulting in the death and capture of several soldiers) DISA LNO
