DD Form 2490-11 is a Department of Defense form, not a service form: DD 2490-11, Network Planning and Configuration Data - Trunk Signaling Buffer B. This form has not been set up to work with a text-to-speech reader. Contact the DoD Forms Manager for further details if this access is required., used to Network Planning and Configuration Data - Trunk Signaling Buffer B. The DD prefix is the operative fact. It means one blank serves every military department — Army, Navy, Air Force, Marine Corps, Space Force, Coast Guard under Defense jurisdiction — plus the defense agencies and combatant commands. No branch variant exists.
Requirement traces to not stated; the form belongs to not stated. Everything about schedule sits below that in local instruction, which is where to ask if a date matters.
Use not stated, status not stated. Older printings circulate widely and lose their currency Department-wide the moment a new edition issues.
Formats: PDF. Length 1 pages, approximately 174 entries. Pick on the basis of how you will complete it.
Take the fillable pdf unless you have a reason not to. Fillable means the boxes are real fields that accept typed text and retain it in the file. Printable means a flat blank — no fields, printer and pen only. The difference is not cosmetic: one produces a record that reproduces cleanly through scanning and forwarding, the other depends on penmanship.
Xfdl needs IBM Lotus Forms Viewer or a compatible client — a pdf reader will not open it. The format was the Defense standard for electronic forms across the Department for years, which is why it persists in DD distribution long after most users moved to pdf.
Free download, every format. Do not fill the form in a browser tab — browser pdf viewers handle interactive fields inconsistently and discard entries on close.
What the form asks for
- Press this Reset button to clear the data from all fields.
Start by matching the printed date to not stated. Old blanks accumulate in shared folders for years. Because the Department reissues to all services in one action, nobody is still accepting the previous layout by local custom.
For anything ambiguous in a specific field, the form's own instructions come first and not stated controls where the two differ.
Send it as not stated or local guidance specifies. Save a copy. Cross-service and cross-agency routing is normal for Department forms, and a lost original outside your own organization is harder to chase down.
Related forms are found by number alone. The DD sequence is one unified Department-wide series, so a cited number resolves to exactly one document with no branch qualifier needed.
Where a procedure cites both a service form and a DD form, the two are unconnected. Service numbering answers to a service proponent, DD numbering to not stated or another Department office, and the two sequences were never aligned. Matching numbers mean nothing whatever.
Revision follows directive changes, changed data requirements and amended notice language, unannounced. Verify not stated each time rather than trusting a saved copy — the cost of the check is seconds.
What is here is the blank form and a description of it. What is not here is legal guidance or any assurance about a particular filing — this page is not the issuing authority and does not speak for one. Those questions go to not stated, to your servicing administrative office, or to the authority identified in not stated.
