ITU-T Contributions & TDoc Procedures
Terminology guardrails (important)
- Contribution (C-series meeting input): regular pre-meeting submission
by authorized members, subject to contribution deadlines.
- Temporary Document (TD): ITU-T internal working document category with
distinct process and role expectations (e.g., chairman/rapporteur/editor
workflows and meeting-time handling).
Do not assume TD in ITU-T is synonymous with generic "TDoc" usage in
other SDO contexts. In ITU-T workflows, treat Contribution and TD as
separate document types with different handling rules.

- TD portal entry point:

Use the local Contribution template for regular pre-meeting submissions and
use the TD portal entry point for TD-specific workflow orientation under
chair/rapporteur/editor processes.
