(a) The advisory commission shall determine by rulemaking what constitutes a local exchange access line and an equivalent local exchange access line for all 9-1-1 emergency services fees imposed statewide.
(b) By October 1, 1999, the advisory commission shall adopt definitions of a local exchange access line and an equivalent local exchange access line that exclude a line from a telecommunications service provider to an Internet service provider for the Internet service provider’s data modem lines used only to provide its Internet access service and that are not capable of transmitting voice messages.

(c) The advisory commission shall annually review the definitions of a local exchange access line and an equivalent local exchange access line to address technical and structural changes in the provision of telecommunications and data services. In that annual review, the advisory commission may include previously excluded Internet service provider data modem lines if it determines that circumstances have changed sufficiently enough that 9-1-1 emergency calls through those lines are done on a regular basis or that the data lines are voice-capable or that the lines are functionally equivalent.
(d) An emergency communication district described by § 771.001(3)(A) or (B) that has not participated in a regional plan shall use the advisory commission’s definitions of a local exchange access line and an equivalent local exchange access line for purposes of imposing its emergency service fees and may not impose an emergency service fee on any line excluded from the advisory commission’s definitions.
(e) A service provider shall collect and remit the emergency service fees to the advisory commission or the appropriate emergency communication district, as applicable, in accordance with the advisory commission’s definition of a local exchange access line and an equivalent local exchange access line.
