Every entry in the Defense records system exists because some decision needed a documented basis, and DD Form 2490-14 is one of those instruments: DD 2490-14, Network Planning and Configuration Data - Diphase Loop Modem A. 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., created to Network Planning and Configuration Data - Diphase Loop Modem A. The reason it carries a DD number rather than a service designation is structural — the Department maintains a single body of forms for matters that arise identically in every service, so that a record created in one component remains intelligible in another.
That decision has consequences you will notice. Because not stated prescribes the form for the Department as a whole, and not stated maintains it on the Department's behalf, the same blank passes between the Army, the Navy, the Air Force, the Marine Corps, the Space Force, the Coast Guard when operating under Defense jurisdiction, the defense agencies and the combatant commands without translation. A clerk in one component reads a record created in another and finds the fields where they expect them.
Current edition: not stated, status not stated. Understand why that date is worth attention here. When the Department reissues a form, the replacement takes effect across every component simultaneously, so an older copy is not merely locally out of date — it is out of date in every office that might receive it.
The sequence printed on the form is the sequence in which a reviewer will read it, and the two should agree. Header data frames every entry below it; the substantive fields depend on that frame; the certification stands at the end because its whole function is to vouch for what came before. Entries made out of sequence commonly contradict entries made earlier.
Check the edition date before you type anything, against not stated. Old blanks accumulate in shared drives for years, and the cost of one is not obvious until a reviewer cannot find a field. Because DD forms are revised centrally and replaced across the Department in a single action, there is no component still tolerating the old layout as a local practice.
For an ambiguous field, read the form's own instruction, then not stated, which controls.
Download the form
What you can download: PDF. The form runs 1 pages and asks for approximately 102 entries.
Nothing here is charged for. Published Defense forms are public documents and distribution carries no fee, in any format. One caution about software: fill the form in a desktop pdf application rather than a browser tab. Browser-embedded viewers implement field behaviour inconsistently, and the failure mode is silent loss of everything you entered.
What the form asks for
- Press this Reset button to clear the data from all fields.
Route the executed form as not stated or local guidance directs, and retain a duplicate first. Cross-component routing is ordinary for DD forms, which is precisely why a personal copy earns its keep: the receiving office may belong to an organization you have no standing to query about a missing document.
Forms referenced inside this one are located by number alone, and that simplicity is a direct product of Department-level numbering. Because the DD sequence is maintained centrally and not duplicated by service, a number is a complete address: one number, one document, throughout the Defense establishment.
Procedures that touch both Department and service processes will cite forms from both sequences, and the coincidence of numbers between them is exactly that — coincidence. An Army proponent maintains the DA series for the Army; not stated or another Department office maintains the DD series for the whole Department. Two independent registries, two independent numbering runs, no correspondence at any value.
Understanding why editions change explains why checking them is not optional. Revision follows directive reissue, changes in what data is required, and amendments to mandatory notice text — decisions made at Department level and communicated through publication rather than notification. The file you saved does not update itself, so the edition date at download is what you rely on.
A word on what this page is. It distributes a published Department of Defense document and describes what the document contains and how it is completed. It is not the issuing authority, does not speak for one, and offers no legal advice; nothing written here determines whether a particular submission will be accepted, because that determination belongs entirely to the office receiving it. Questions of applicability, eligibility or procedure go to not stated, to your servicing personnel office, or to the office identified in not stated.
