DTNSRDC has established the Technical Office Automation and Communications System (TOFACS) to utilize modern office automation technologies. A pilot broadband network was installed to study the effects of a high speed network on the productivity of TOFACS. DTNSRDC installed the MITRENET Local Area Network (LAN) with the objective of experiencing the use and management of a LAN with the intention of eventually installing a permanent, full scale LAN at DTNSRDC. MITRENET is a network product of MITRE CORP. There are four versions of MITRENET. All four versions use a Network Interface Unit (NIU) or more commonly known as a BIU (Bus Interface Unit) which employs Carrier Sense Multiple Access with Collision Detection (CSMA/CD) network access techniques. The Mclean version differs significantly from the previous versions in that it is based on a z8000 microprocessor and is able to support the Department of Defense, Transmission Control Protocol (TCP) and Internet Protocol (IP) standards. The previous versions do not support TCP or IP and have considerably less capability.
