2. Abstract The period of 1950 to 1960 represented an unprecedented buildup of US military forces in Europe. This was accompanied by a strategic long lines comm. requirement unparalleled in the history of the U.S. Army. Limited technology required adaptation of existing commercial equipment. The 102d Signal Bn. (MW&RR) provided a multichannel backbone for USAREUR from 1955 to 1967. 4/25/20082 U.S. Army Electronic Technology & Devices Lab. Fort Monmouth,NJ

4. Occupation and the Constabulary Long Line recovery of the German Infrastructure (Lorenz VHF) Deutche Post was required. German underground wire infrastructure not suitable for Army use. No strategic theater system in place, only various tactical net to net Comm. 4/25/20084 U.S. Army Electronic Technology & Devices Lab. Fort Monmouth,NJ

5. Berlin Blockade Demonstrated Occupation level communications inadequate. Berlin cable and telephone lines cut. HF jammed. Deutche Post Bocksberg link to Berlin only multichannel available (commercial). Realigned national policy to defend Western Europe. 4/25/20085 U.S. Army Electronic Technology & Devices Lab. Fort Monmouth,NJ

6. Reach Back Two cables available, Hamburg(diplomatic) and Cherbourg. Army ACAN network used HF radio, limited to 2 or 3 voice channels, 15 TTY channels. HF sites at Orleans and Neuostheim. Tape radio relay sites use manual paper to paper transfer. HF affected by sun spots, outages for days. 4/25/20086 U.S. Army Electronic Technology & Devices Lab. Fort Monmouth,NJ

42. Troposcatter; the beginning of the end Troposcatter emerged from the Signal Corps Labs in the early 1960. Did not require line of sight operation. Extended distances and decrease no. of relays No need for manpower intensive relays and difficulty to defend those relays. Feasibility demonstrated in Viet Nam using commercial equipment ( BACK PORCH). 4/25/200842 U.S. Army Electronic Technology & Devices Lab. Fort Monmouth,NJ

43. The System is Aging Demands of wideband requirements in the 1960’s Tax the network. Viet Nam experience shows value of tropo. Planners are delayed due to Viet Nam needs. Signal Corps Labs Develop military hardware. STRATCOM planners evolve to new system. Change over begins. 102d Signal Bn. Will not be the new owner. 4/25/200843 U.S. Army Electronic Technology & Devices Lab. Fort Monmouth,NJ

44. The End The USAREUR Multichannel Radio Telephone Network is decommissioned in Nov. 1967. The 102d Signal Bn is deactivated shortly. The 68 th Signal Bn. Takes over all remaining sites that remain active using tropo. Additional duties include CEMATARY network. This becomes the forerunner of the ET/A backbone (digital). 4/25/200844 U.S. Army Electronic Technology & Devices Lab. Fort Monmouth,NJ
