The format and contents of the TLM word and the HOW, as well as those of words threethrough ten of each subframe/page, are described in the following subparagraphs. The timing of the subframes andpages is covered in Section 40.3.4.40.3.3.1 Telemetry Word. The TLM word shall be as specified in Appendix II, Section 20.3.3.1.40.3.3.2 Handover Word (HOW).
The HOW shall be as specified in Appendix II, Section 20.3.3.2.40.3.3.3 Subframe 1. Subframe 1 shall be as specified in Appendix II, Section 20.3.3.3.40.3.3.4 Subframes 2 and 3. Subframes 2 and 3 shall be as specified in Appendix II, Section 20.3.3.4.40.3.3.5 Subframes 4 and 5. Both subframe 4 and 5 are subcommutated 25 times each; the 25 versions of thesesubframes are referred to as pages 1 through 25 of each subframe. With the possible exception of "reserved forsystem use" pages and explicit repeats, each page contains different specific data in words three through ten. Asshown in Figure 40-1, the pages of subframe 4 utilize seven different formats, while those of subframe 5 use two.The content of words three through ten of each page is described below, followed by algorithms and materialpertinent to the use of the data.40.3.3.5.1 Content of Subframes 4 and 5.
