Last week, the Commission adopted an IP Transition Report and Order (Order) on the transition of legacy networks to next-generation networks.  Under the Order, incumbent local exchange carriers (ILECs) have discretion as to when and where copper facilities will be retired but must provide business customers and consumers three months’ notice of any copper retirements (and fiber replacements).  The Order also adopts an interim rule obligating ILECs that discontinue time division multiplex (TDM)-based services to provide competitive carriers with replacement services at rates, terms and conditions reasonably comparable to legacy services.  ILECs are authorized to withdraw and replace services without prior FCC approval so long as service is not discontinued, reduced, or impaired. The FCC also issued a Further Notice of Proposed Rulemaking (FNRPM) to define the criteria for determining whether a service (being replaced) has been discontinued, reduced or impaired.
