11 supplied information.” In re Amendment of Section 64.702 of the Commission’s Rules and Regulations (“Computer II”), 77 F.C.C. 2d 384, 420 ¶ 96 (1980). Enhanced services consisted of “any offering over the telecommunications network which is more than a basic transmission service,” for example, one in which “computer processing applications are used to act on the content, code, protocol, and other aspects of the subscriber’s information,” such as voicemail. Id. at 420 ¶ 97. The rules subjected basic services, but not enhanced services, to common carrier treatment under Title II of the Communications Act. Id. at 387 ¶¶ 5–7. Among other things, Title II requires that carriers “furnish . . . communication service upon reasonable request,” 47 U.S.C. § 201(a), engage in no “unjust or unreasonable discrimination in charges, practices, classifications, regulations, facilities, or services,” id. § 202(a), and charge “just and reasonable” rates, id. § 201(b). The Computer II rules also recognized a third category of services, “adjunct-to-basic” services: enhanced services, such as “speed dialing, call forwarding, [and] computer-provided directory assistance,” that facilitated use of a basic service. See In re Implementation of the Non-Accounting Safeguards (“Non-Accounting Safeguards Order”), 11 FCC Rcd. 21,905, 21,958 ¶ 107 n.245 (1996). Although adjunct-to-basic services fell within the definition of enhanced services, the Commission nonetheless treated them as basic because of their role in facilitating basic services. See Computer II, 77 F.C.C. 2d at 421 ¶ 98 (explaining that the Commission would not treat as an enhanced service those services used to “facilitate [consumers’] use of traditional telephone services”). Fifteen years later, Congress, borrowing heavily from the Computer II framework, enacted the Telecommunications Act
