C2MS11 — Align TLM Messages against Subject Elements and Fields

Issue C2MS11-54, already approved, has removed two subject elements that didn't belong in Telemetry TDM Frame Message. In fact, there are many more similar irregularities across all the Telemetry messages.

The needed changes are described below, but also shown in the attachment (original and revised) that shows the fields and subject elements as they exist today and should be after corrected.

• Add a new message type: Telemetry CCSDS CADU Message
• Rename Telemetry CCSDS Frame Message to Telemetry CCSDS Transfer Frame Message
• APID should be both a subject element and field in Telemetry CCSDS Packet, and in no other TLM messages.
• VCID should be both a subject element and field in Telemetry CCSDS Packet and Telemetry CCSDS Transfer Frame, and in no other TLM messages
• PHY-CHAN should be a field in the new Telemetry CCSDS CADU Message, with no subject element for it (Note that this message won't have APID, VCID or SCID represented.
• Add SCID as a subject element and field in Telemetry CCSDS Packet and Telemetry CCSDS Transfer Frame messages
