Abstract:
This standard defines the method for transporting variable-length, well-defined data formats in a Chapter 4 pulse code modulation PCM stream. Packet telemetry defines the method for asynchronously inserting data from one or more data streams into PCM minor frames. This standard defines various source packet SP types that are used to encapsulate well-defined data formats, including Chapter 11 packets Chapter 24 TmNSMessages Ethernet frames. An SP is encapsulated into an integral number of encapsulation packets EPs nominally each EP contains only one SP. Different SP types may be multiplexed simultaneously into a single, logical stream of EPs. The encapsulation packet stream is then segmented into fixed-length transport packets TPs, each of which is inserted into a single PCM minor frame. While a TP may be segmented and interspersed with PCM data within a PCM minor frame, each PCM minor frame shall contain only one TP. A low-latency encapsulation packet LLEP mechanism allows for the insertion of one or more EPs with low-latency requirements into the transmission of a long EP. Specific structure-critical elements are protected using a Golay code see Appendix 7-A for details. Figure 7-1 provides an overview of the entire packet telemetry encapsulation process.
