FCC orders

In the UNE Remand Order issued on November 5, 1999, the FCC specified the UNE to which a competitor must be provided access: "the 'loops' that connect the switches to end users, including high-capacity loops; the switches (with some exceptions), the transport facilities between switches and other networks, and the software needed to operate the telephone network". In the Line Sharing Orders (Line Sharing Order, 14 FCC Rcd at 20951), the LECs are required to unbundle the high-frequency portion of the loop of DSL.http://www.fcc.gov/Bureaus/Common_Carrier/Orders/2001/fcc01026.pdf However, both the UNE Remand Order and the Line Sharing Orders were remanded by the D.C. Circuit Court of Appeals in ''United States Telecom Association v. FCC'' (290 F.3d 415), decided on May 24, 2002; the Line Sharing Orders were

. The court concluded that the FCC had not considered the availability of competitive facilities on a sufficiently granular basis. The FCC eliminated mandatory DSL unbundling in 2003.

Prices

Based on the

, the FCC could require LECs to provide UNEs at a cost-based price, which may include a "reasonable profit". The FCC has determined that "cost" means forward-looking economic cost and has required the states to use a methodology called total element long-run incremental cost (TELRIC).
