NXX Code Transfers

An exiting CLEC must make transfer arrangements with the telephone numbering administrator at least 66 days prior to the migration (or by such earlier date as may be specified by the code administrator) for any NXX codes or thousand number blocks assigned to it. Applicant states that it intends to retain its NXX codes because its affiliate will be using them for "the digital product."¹⁵ Comcast Phone-CA will "rehome"¹⁶ its assigned NXX codes and blocks from AT&T's switches once an NXX code drops below a 10% utilization threshold on the AT&T switches.¹⁷ Applicant will provide CD with a copy of the associated NXX Code Administrator documentation, if requested. The NXX code transfer requirement is inapplicable when, as here, Applicant intends to retain its NXX codes.

¹⁵ The Voice over Internet Protocol (VoIP) telephone service.

¹⁶ Rehoming is a major network change which involves moving a customer's local loop termination from one Central Office wire center to another. Rehoming generally involves the re-termination of private line facilities, although it can simply involve local termination for purposes of access to switch services. Rehomes also can be for the purposes of the carrier, perhaps in connection with the switch upgrade or switch move/decommission. Newton's Telecom Dictionary at p. 659 (1999).
