Defense Department form, series DD, number 2490-21. Full title: 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.. Function: Network Planning and Configuration Data - Digital Loop and Trunk Worksheet. Edition in force: not stated. Publisher status: not stated.
Governing directive: not stated. Responsible office: not stated. The DD designation signals joint scope — all military departments, combatant commands and defense agencies draw on a single edition of the document.
Common users: service members regardless of branch, Defense civilian staff, and the offices that file, verify or retain the finished document.
Submission follows the schedule set by not stated and by local implementing procedures. This page provides the blank form for download and general orientation only.
The download set covers PDF. Document length is 1 pages with about 200 entry fields.
Distribution centres on pdf. Two states exist: fillable, where field boxes accept keyboard input and retain it, and printable, a static blank produced for manual completion. Typed data reproduces cleanly across copies; handwritten data depends on the writer.
The xfdl release corresponds to IBM Lotus Forms. This format carried Department-wide form distribution for years and opens only in IBM Lotus Forms Viewer or a compatible client, not in a pdf reader.
Free download applies to every format listed. Any current pdf reader opens the pdf files, though field behaviour is most reliable in a full desktop reader rather than a browser preview.
What the form asks for
- Press this Reset button to clear the data from all fields.
Completion runs in the order printed on the page: identifying data at the head, the body of the entry next, certification at the foot. Header data frequently governs what belongs in the fields below it.
The current edition is not stated. Superseded editions of DD forms are frequently rejected at the receiving office, since Department-wide forms change centrally and older layouts lose their field correspondence. Edition date appears in the lower corner of the printed blank.
Instructions printed on the form or in not stated govern individual field entries. Where the two differ, the governing publication controls.
After completion, the copy goes to the office designated by not stated or by local procedure. Retention of a personal copy is ordinary practice and costs nothing.
Cross-referenced forms are found through the numbering system. The DD sequence is Department-level and unified, which means a number cited on the page identifies one document across the whole Department.
Some procedures pair a DD form with a service form. The two numbering systems are separate — service forms answer to a service proponent, DD forms to not stated or another Department office — and a matching number in each system means nothing.
Forms are reissued for several reasons: directive revision, changed data requirements, updated notice language. Confirming not stated at the moment of download covers the risk.
This page distributes a published Department of Defense document and describes it. It is not a source of legal advice and makes no representation about acceptance of any completed form. Questions of applicability, eligibility or procedure belong to not stated, the servicing personnel office, or the office named in not stated.
