Unformatted text preview: as developed by consolidating the specifications regarding synchronization and channel coding in older CCSDS Recommended Standards (references [E2] and [E3]). This Recommended Standard does not change the major technical contents defined in references [E2] and [E3], but the presentation of the specification has been changed so that: a) these schemes can be used to transfer any data over any space link in either direction; b) all CCSDS space link protocols are specified in a unified manner; c) the layered model matches the Open Systems Interconnection (OSI) Basic Reference Model (reference [3]). Together with the change in presentation, a few technical specifications in references [E2] and [E3] have been changed in order to define all Space Data Link Protocols in a unified way. Also, some technical terms in references [E2] and [E3] have been changed in order to unify the terminology used in all the CCSDS Recommended Standards that define space link protocols and to define these schemes as general communications schemes. These changes are listed in annex H of this Recommended Standard. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change control procedures, which are defined in the Procedures Manual for the Consultative Committee for Space Data Systems.
