Currently, the DoD is establishing the requirements for a DoD Teleport system. The DoD Teleport will integrate, manage, and control the communications interfaces between the Defense Information System Network (DISN) terrestrial and SATCOM assets at single point of presence. The DoD Teleport will provide for satellite communications at X, C, Ku, civil and military Ka, EHF,and possibly other frequency bands to provide the throughput required by deployed users. Deployed warfighters will be able to access pre-positioned DISN services at DoD Teleport sites strategically located around the world. This paper describes the interfaces required at the DoD Teleport to successfully integrate the current EHF SATCOM system, Milstar, with the DISN. This paper also demonstrates how the DoD Teleport can reduce the number of satellite resources used in situations wheretactical EHF users require reach-back capability.

The current Department of Defense (DoD) satellite communications architecture relies heavily on point-topoint, circuit-based communications technology, which is an inherently inefficient use of bandwidth resources. The current Global War on Terror (GWOT) and Operations Iraqi (OIF) and Enduring Freedom (OEF) demand a more efficient and scalable infrastructure to support Warfighter transformation. To meet these emerging requirements, the Defense Information Systems Agency (DISA) DoD Teleport Program Office (TPO) is building an initial transformational net-centric architecture by the end of Fiscal Year (FY) 2005 with significant upgrades starting in FY2006. The DoD Teleport system provides the deployed Warfighter access to the Global Information Grid (GIG) by linking the space and ground segments through a worldwide, pre-positioned military and commercial satellite communications infrastructure. Through multiple radio frequency (RF) media (military and commercial bands), Teleport provides inter-theater reach-back into the Defense Information Systems Network (DISN) and Service Command, Control, Communications, Computer, and Intelligence (C4I) systems, as well as intra-theater communications support for tactical users. These interfaces enable the seamless, interoperable, and secure transport of command and control (C2), intelligence, surveillance, reconnaissance (ISR), and mission critical information supporting Warfighter global operations.The TPO net-centric Teleport architecture converges all the voice, video, and data requirements into a single Internet Protocol (IP)-based transport system, consisting of: 0 0 0 Satellite IP-based networking modems, A "black" convergence router suite, and A Voice over IP (VoIP) gateway for unclassified voice.This architecture, combined with the Global Network Operations (NetOps) construct, will enable significant bandwidth efficiencies for greater reach-back and enhanced warfighting capabilities through dynamic bandwidth allocation required for advanced capabilities such as unmanned aerial Intelligence, Surveillance, and Reconnaissance (ISR) missions.As part of the Department's transformation, the Teleport net-centric and circuit-based architecture will exist in parallel for some time to enable a gradual transition by the deployed warfighter. This architecture will be implemented in two phases beginning with a Limited-IP design at two sites in FY05 followed by a worldwide implementation at all DoD Teleport locations. This paper highlights the implementation and intended operations of the new, netcentric Teleport. BACKGROUNDThe Joint Requirements Oversight Council (JROC) approval of Teleport Generation One and Two Operational Requirements Documents (ORD) validated an operational need for the rapid establishment of C41 connectivity in support of worldwide operations.Teleport is a telecommunications collection, transport, and distribution point providing the deployed Warfighter with multi-band and multi-media satellite communication capability and seamless access to terrestrial compon...
