WIRELINE COMPETITION BUREAU ANNOUNCES PUBLICLY AVAILABLE SOURCES IN 
THE SPECIAL ACCESS NPRM PROCEEDING
WC Docket No. 05-25, RM-10593
In January 2005, the Commission initiated a broad inquiry into the regulatory framework
applicable to price cap local exchange carriers’ (LECs) interstate special access services.1 The 
Commission subsequently sought to refresh the record in the Special Access NPRM proceeding, and 
invited interested parties to propose an analytical framework that the Commission could apply to assess 
competitive conditions for special access.2 Most recently, the Commission issued two voluntary data 
requests, which sought to obtain data from special access providers and customers about special access 
facilities, pricing, and competition.3
Consistent with the questions the Commission has asked thus far, and to ensure a high level of 
transparency in the rulemaking process, the attached appendix provides a list of publicly available 
documents that the Commission may consider as part of this proceeding.
For further information, contact Jamie Susskind of the Pricing Policy Division, Wireline 
Competition Bureau at (202) 418-1520.
