ADSL2+ broadband technology
FCC Form 477 technology code 11: 3,788,469 census-block deployment records nationwide. Filing volume and state reach are separate measurements.
Filing volume rank is not state-reach rank
ADSL2+ ranks #4 of 10 FCC technology codes by census-block records, and #6 of 10 by number of states with at least one filing (50 states).

Top states for ADSL2+ by reported deployment records
FCC Form 477 fixed broadband deployment data (June 2020 status)
California leads ADSL2+ filings with 383,081 records ; Texas is second at 341,320. Counts are provider-by-census-block filings for technology code 11, not subscriber totals.
About ADSL2+
ADSL2 / ADSL2+ is an enhanced form of Asymmetric DSL that delivers internet over traditional copper telephone lines. Download speeds are faster than upload speeds, reaching up to roughly 24 Mbps, and it is widely available wherever telephone infrastructure exists.
ADSL2+ filing-volume reading
ADSL2+ opens on filing volume: #4 of 10 FCC technology codes by census-block records (3,788,469 filings). FCC technology code 11 is a copper / DSL family label in Form 477.
Among the 10 Form 477 technology codes on this site, ADSL2+ sits in the upper third by record volume (≥ 3,788,469). That scale usually means many operators mark many census blocks, not that every marked block has active subscribers.
The lead state (California) holds 10.1% of ADSL2+ filings (383,081 records). That is a moderate peak: several states still move the national total. Form 477 historically let providers mark a whole census block from a single reachable address; treat these counts as declared capability, not address-level availability, speed, or price.
