Are telecommunications carriers required to interconnect their networks with other carriers?

Published 2026-06-23 · U.S. federal law

Section 251 imposes a general duty on each telecommunications carrier to interconnect directly or indirectly with the facilities and equipment of other telecommunications carriers.

The answer

The general interconnection duty

47 U.S.C. § 251(a) provides that each telecommunications carrier has the duty to interconnect directly or indirectly with the facilities and equipment of other telecommunications carriers, and not to install network features that do not comply with applicable guidelines.

Heightened duties for incumbents

Section 251(c) layers additional obligations on incumbent local exchange carriers, including duties to negotiate in good faith and to provide interconnection at any technically feasible point on rates that are just, reasonable, and nondiscriminatory.

This is an excerpt from a draft FCC licensing opinion — the kind of work product a lawyer generates with a legal-AI drafting tool, then has to stand behind. Kingsfield does not write it; it rules on the citations the model put in it. This draft cites two authorities; one of them is wrong.

AI draft excerpt — FCC licensing opinion

The Company, as a telecommunications carrier, must connect its network to other carriers rather than operate in isolation. Under 47 U.S.C. § 224, each telecommunications carrier has the duty to interconnect directly or indirectly with the facilities and equipment of other telecommunications carriers. We advise that interconnection agreements be reviewed against that general duty, codified at 47 U.S.C. § 251(a). The heightened obligations applicable to incumbent carriers should be analyzed separately.

The judge ruled on every citation as the draft used it — it accepted 47 U.S.C. § 251(a) and rejected 47 U.S.C. § 224. Here is why.

How Kingsfield ruled

Ruled 2026-06-23

Each citation in the draft above was submitted to the Kingsfield judge and ruled against the primary-law corpus — Accept, Reject, or Inconclusive, per citation. These are live verdicts, not editorial. Each card shows the claim the draft made and the verbatim authority the verdict was rendered against.

Accept47 U.S.C. § 251(a)

The draft claimed: Each telecommunications carrier has the duty to interconnect directly or indirectly with the facilities and equipment of other telecommunications carriers.

“§ 251(a) Each telecommunications carrier has the duty—”

Cite found; proposition supported by the cited text.

Reject47 U.S.C. § 224

The draft claimed: Section 224 is the provision imposing on each telecommunications carrier the general duty to interconnect with the facilities and equipment of other telecommunications carriers.

Cite found, but the cited text does not support the claim. 47 U.S.C. 224 governs pole attachments and access to poles, ducts, conduits, and rights-of-way owned by utilities; the general interconnection duty is set by 47 U.S.C. 251(a). Regenerate with the correct authority.
