This file posted by the Wireline Competition Bureau documents the “Required Locations” to which incumbent local exchange carriers (ILECs) that elected Enhanced Alternative Connect America Model (Enhanced A-CAM) support must deploy. The purpose of this file is to permit the Universal Service Administrative Company to identify Broadband Serviceable Locations (BSLs) that Enhanced A-CAM recipients may (and ultimately must) report in the High-Cost Universal Broadband (HUBB) portal to demonstrate compliance with their deployment obligations. Enhanced A-CAM carriers will not be able to report in the HUBB deployment to any BSL not on this list.
The Required Locations in this file match the locations in the Interim Eligible Locations file, last updated on October 25, 2024 that have an indicator that 100/20 Mbps or faster broadband is required. As noted in that file, the Required Locations are determined based on the Broadband Serviceable Location Fabric (Fabric) Version 4, and broadband availability is determined based on the June 30, 2023 Broadband Data Collection (BDC) for all BSLs in Version 3 of the fabric and December 31st, 2023 BDC data for V4 locations not in fabric V3.
Pursuant to the Enhanced A-CAM Order, the Wireline Competition Bureau has until December 31, 2025, to finalize the support amounts and Required Locations for Enhanced A-CAM recipients. As a consequence, this list of Required Locations is subject to future updates.
