The Federal Communications Commission’s (FCC) order seeking comment on additional safeguards to protect customer proprietary network information (CPNI) has been published in the Federal Register, triggering comment and reply comment deadlines of July 9, 2007, and August 7, 2007, respectively. Many of the issues raised in this proceeding are the same, or build upon, issues raised in response to the EPIC Petition, which the FCC responded to through its order released in April (FCC 07-22). This Client Advisory discusses the issues the FCC is seeking comments on, each of which has the potential to affect the manner in which companies do business and treat CPNI.
