STANAG 3910
STANAG 3910 ''High Speed Data Transmission Under STANAG 3838 or Fibre Optic Equivalent Control''〔〔 is a protocol defined in a NATO Standardization Agreement for the transfer of data, principally intended for use in avionic systems. STANAG 3910 allows a 1 Mb/s STANAG 3838〔 / MIL-STD-1553B / MoD Def Stan 00-18 Pt 2 (3838/1553B) data bus to be augmented with a 20 Mb/s high-speed (HS) bus, which is referred to in the standard as the HS channel: the 3838/1553B bus in an implementation of STANAG 3910 is then referred to as the low-speed (LS) channel. Either or both channels may be multiply redundant, and may use either electrical or optical media. Where the channels use redundant media, these are individually referred to as buses by the standard.〔〔

The original STANAG 3910, i.e. the NATO standard, reached, at least, draft version 1.8,〔 before work on it was abandoned in the early 1990s in favour of its publication through non-military standardization organizations: the foreword to Rev. 1.7 of the STANAG from March 1990 stated "The main body of this document is identical to the proposed Rev 1.7 of prEN 3910".〔 Following this, several provisional, green-paper versions, prEN 3910 P1 & P2, were produced by working-group C2-GT9 of the ''Association Europeene des Constructeurs de Materiel Aerospatial'' (AECMA) (now ASD-STAN),〔 before its development also ceased in 1996-7 (following the withdrawal of the French delegation, who held the chair of AECMA C2-GT9 at the time). As a result, the standard remains (as of Aug. 2013) in green paper form: the latest draft version is prEN3910-001 Issue P1, the front sheet of which states, 'This "Aerospace Series" Prestandard has been drawn up under the responsibility of AECMA (The European Association of Aerospace Industries). It is published on green paper for the needs of AECMA-Members.'〔 However, despite this disclaimer, the document is offered for sale by ASD-STAN, currently (August 2013) at €382.64.〔
