You need DD Form 2490-21, and this page gives you the blank plus the steps for handling it. Start with what the form does: Network Planning and Configuration Data - Digital Loop and Trunk Worksheet. Its official title is DD 2490-21, Network Planning and Configuration Data - Digital Loop and Trunk Worksheet. 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..
Then look at the edition date: not stated, publisher status not stated. After that, ask whether the form covers your situation. It almost certainly does regardless of your branch — DD forms run Department-wide rather than through a single service.
Then settle the schedule. You are working under not stated, with not stated responsible for the document, and your organization layers its own deadlines on that. Ask before you assume a date.
Finally, decide how you will complete it. You can type into a fillable file or print a blank and write by hand, and the rest of this page walks you through both paths in order.
Begin at the top and move down. Enter your identifying data first, then the body of the form, then the signature block. The sequence is printed in that order because entries below frequently follow from entries above.
Before your first entry, look at the corner of the page and compare the printed date with not stated. If they do not match, stop and download again. Old copies circulate in shared drives for years, and a DD form is revised centrally for every service at once, so a superseded blank may not carry the fields your reviewer expects.
For questions about a specific entry, check the form's own instructions, and if that does not settle it, open not stated. The directive controls where they differ.
Download the form
Step one is picking the format. You have PDF to choose from, across 1 pages, with approximately 200 fields to complete.
Choose pdf as your default. Next, click inside a box. A fillable pdf responds by outlining the field and letting you type; the text stays in the document when you save it. A printable pdf does not respond, which tells you to print the page and complete it by hand.
Type when you can. Printed entries stay legible after the form is scanned, copied and forwarded, and handwriting often does not survive that trip. If you must write by hand, use block capitals and press firmly.
Check your software before choosing xfdl. That format belongs to IBM Lotus Forms, long used for Defense form distribution, and it needs the matching viewer. Get the viewer installed, then come back for the file.
Whichever you pick, you pay nothing — every format here is a free download. One last tip: open your pdf in a desktop reader rather than in a browser tab, because browser viewers sometimes drop the interactive fields you need.
What the form asks for

Now that it is complete, send it where not stated or your local procedure says it goes. Before you do, make yourself a copy — scan it or save the file elsewhere. It costs you nothing and saves you the whole exercise if the original goes missing.
Should you need a related form, look it up by its number. The DD sequence is Department-wide, which makes your search simple: no service qualifier, no branch-specific variant to track down.
Watch out for one trap here. If your instructions cite a DA form as well, do not assume the numbers are connected. DA numbering belongs to the Army alone; DD numbering belongs to the Department and is administered by not stated or another Department office. The same number in each system means two unrelated forms, so read the prefix before you download.
Come back and check the edition next time you need this form. Editions change when the prescribing directive is reissued, when the information collected changes, or when the required notice language is updated, and none of those events reaches you directly. Verifying not stated at the moment you download is the whole defence.
One thing this page does not do: tell you whether your submission will be accepted. We publish the document and explain how to complete it, and that is where our role ends. Nothing here is legal advice. Take questions about eligibility, applicability or procedure to not stated, to your servicing personnel office, or to the office named in not stated.
