Smesta

The process of communicating air surveillance and tactical data information between command and control systems or between facilities within the systems. Telling may be classified into the following types: a. Back tell - The transfer of information from a higher to a lower echelon of command. b. Cross tell - The transfer of information between facilities at the same operational level. c. Forward tell - The transfer of information to a higher level of command. d. Overlap tell - The transfer of information to an adjacent facility concerning tracks detected in the adjacent facility's area of responsibility. e. Relateral tell - The relay of information between facilities through the use of a third facility. This type of telling is appropriate between automated facilities in a degraded communication environment.
