§52.35   Porting Intervals.

(a) All telecommunications carriers required by the Commission to port telephone numbers must complete a simple wireline-to-wireline or simple intermodal port request within one business day unless a longer period is requested by the new provider or by the customer. The traditional work week of Monday through Friday represents mandatory business days and 8 a.m. to 5 p.m. represents minimum business hours, excluding the current service provider's company-defined holidays. An accurate and complete Local Service Request (LSR) must be received by the current service provider between 8 a.m. and 1 p.m. local time for a simple port request to be eligible for activation at midnight on the same day. Any simple port LSRs received after this time will be considered received on the following business day at 8 a.m. local time.

(b) Small providers, as described in the 2009 LNP Porting Interval Order, must comply with this section by February 2, 2011.

(c) Unless directed otherwise by the Commission, any telecommunications carrier granted a waiver by the Commission of the one-business day porting interval described in paragraph (a) must complete a simple wireline-to-wireline or simple intermodal port request within four business days unless a longer period is requested by the new provider or by the customer.

(d) All telecommunications carriers required by the Commission to port telephone numbers must complete a non-simple wireline-to-wireline or non-simple intermodal port request within four business days unless a longer period is requested by the new provider or by the customer.

(e) For purposes of this section:

(1) The term “local time” means the predominant time zone of the Number Portability Administration Center (NPAC) Region in which the telephone number is being ported; and

(2) The term “intermodal ports” includes

(i) Wireline-to-wireless ports;

(ii) Wireless-to-wireline ports; and

(iii) Ports involving interconnected VoIP service.
