Main Page | See live article | Alphabetical index In telecommunication, a block transfer attempt is a coordinated sequence of user and telecommunication system activities undertaken to effect transfer of an individual block from a source user to a destination user. Note: A block transfer attempt begins when the first bit of the block crosses the functional interface between the source user and the telecommunication system. A block transfer attempt ends either in successful block transfer or in block transfer failure. Source: from Federal Standard 1037C This article is from Wikipedia.
