To do in Panel switch

[edit]
  • It's organized by components, but some section headers (like "Stuck sender") are not clearly components. Fix this.
  • Add more section headers when needed.
  • My edits to add "Telephone numbering" etc. introduce useful background information, but need to be reorganized.
  • Make my style match the original.
  • Expand abbreviations like SXS.
  • Try to introduce concepts/terms in only one place, as early as possible.
  • See copy/move notes in next section.
  • If current polarity is only used for synchronization, it doesn't carry information; thus I believe the comment about bit-to-baud ratio is wrong. Check with other people.
  • Check titles and page numbers (or URLs) cited. Add links to references, or citations.
  • Needs background information. When was it invented? Who invented it, AT&T or another organization? How long was it used? Which other types of equipment work with it? Specific people, dates, etc.?
  • Clarify that it was invented to work in the US, so it is tied into the US numbering and office organization system. Be brief, however.
  • Need picture of a call indicator. Encoder might be interesting. Other pictures might be interesting.
  • Write examples. Cases: 4 digits, 4 digits + party, 5 digits. If possible, use real Seattle numbers.
  • Scan of part of a phone book page showing party line entries, or manual office line numbers >10000, would be interesting.
  • Copy or move information about sending 7 digits (used in tandem offices) from Panel office. I need more information about # digits and encoding as they evolved over the years. Sending to a call indicator is not the same as sending to a register in a tandem office.
  • Correct, then copy or move information about bit-to-baud ratio from Panel office.
  • Explain meanings of names for digit "slots", particularly Stations. A "station" = an individual telephone = an individual telephone in a party line, but the stations digit is also used for ten-thousands.
  • Or perhaps remove the word "stations" from the table.
  • Add information about the heavy positive pulse (at time 17) once I understand it.
  • Find schematics and add information about how unused combinations are decoded? It may have changed over the years.
  • Consider using background color to distinguish 0 from 1 bits, since that's more important than polarity.
  • Ask blind users about Braille and speech accessibility.
  • I couldn't figure out how to use nested tables, but it may still be possible.
  • Add a link from "PCI" page.
  • Check titles and page numbers (or URLs) cited. Add links to references, or citations.
