MAKING CONNECTIONS


After decommissioning the old telephone system at Fort Leonard Wood, I3MP installed clear fiber- optic patch panels that allow cables to be cross-connected in a controlled environment. (U.S. Army photo by Scott Sundsvold, I3MP Strategic Communications)


The end result is a new telephone solution that reduces the time needed to establish commercial service from months to weeks while eliminating the need to maintain legacy circuits and equipment.


When the Army decided to modernize its telephone system, it called upon the Installation Information Infrastructure Modernization Program (I3MP), part of the Program Executive Office for Enterprise Information Systems (PEO EIS). I3MP supports the Soldier through information technology, infrastructure modernization and life cycle manage- ment of the Army’s Installation Campus Area Networks and command centers within the continental United States.


Te I3MP office set out to deliver installa- tion capability sets using state-of-the-art information technology to connect Army customers to the network. Tis involves converting installation voice circuits to IP, transitioning from TDM to Voice over Internet Protocol (VOIP) technology and

connecting to Defense Information Sys- tems Agency (DISA) VOIP architecture.


From 2013 to 2017, I3MP performed an installation capability set moderniza- tion on Fort Leonard Wood, Missouri, to move approximately 19,900 users to an IP-based communication system. By upgrading its network with IP communi- cations, Fort Leonard Wood has reduced the operations and maintenance costs for its voice services while providing Soldiers with new collaboration capabilities to improve timely knowledge exchange and decision-making by Army leaders.


Fort Leonard Wood is the first Army installation to use DOD’s Assured Ser- vices Session Initiation Protocol (AS-SIP) trunking for Defense Switched Network
