The scope here is Department-wide. DD Form 2490-8 — DD 2490-8, Network Planning and Configuration Data - Mux/Demux Strapping. 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. — exists to Network Planning and Configuration Data - MUX/DEMUX Strapping, and it applies across the services rather than inside one. That is what the DD prefix encodes: joint issue, single edition, every branch and defense agency working from identical paper.
not stated is the prescribing publication and not stated the office responsible for the document. Deadlines belong to local implementing guidance, not to either of those, so a submission date is a question for the receiving office.
Use not stated, status not stated. Older printings circulate widely and lose their currency Department-wide the moment a new edition issues.
The set is PDF. Size: 1 pages, about 200 fields. Everything below refines that choice.
Default to fillable pdf, print only when you must. The fillable file stores what you type; the printable file is a blank picture. A Department form often travels further than a service form — scanned, emailed, forwarded to an agency that never saw the original — and typed text is what survives that.
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.
Sequence matters. Identification precedes content, content precedes certification, because the lower half of a form is generally conditioned on the upper half.
Mark inapplicable items N/A rather than leaving white space. Use the date format the form specifies. This matters more on Department forms than on service forms: the record may be reviewed by personnel outside your branch who share none of your office conventions.
The Privacy Act Statement precedes the personal data fields for a reason. It gives the collection authority, the principal purpose, the routine uses and whether disclosure is voluntary or mandatory. Read it while the disclosure decision is still yours to make.
Signature comes after everything else and must be a signature: pen, or a credentialed digital signature via Common Access Card. Typing does not qualify. Add the date at the same moment.
Final pass, against the standing defect list: superseded edition, empty mandatory fields, handwriting illegible after scanning, non-conforming dates, missing signature or date. 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.
A number is a complete address in the DD series. Because the sequence is Department-level and not duplicated per service, there is nothing further to specify.
Prefix before number. A DA citation and a DD citation in the same instruction point at separate systems — one Army, administered by an Army proponent, one Department-wide under not stated — and there is no correspondence between them at any number.
Editions change when the prescribing directive is reissued, when the data collected changes, or when notice language is amended. None of that reaches you. Checking not stated at download is the entire defence, and it is cheaper than repeating a submission.
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.
