   (a) For purposes of § 64.2309, a telecommunications carrier provides
   subscriber list information on a timely basis only if the carrier

   publisher either:

   (1) At the time at which, or according to the schedule under which, the
   directory publisher requests that the subscriber list information be
   provided;

   (2) When the carrier does not receive at least thirty days advance
   notice of the time the directory publisher requests that subscriber
   list information be provided, on the first business day that is at
   least thirty days from date the carrier receives that request; or

   (3) At a time determined in accordance with paragraph (b) of this
   section.

   (b) If a carrier's internal systems do not permit the carrier to
   provide subscriber list information within either of the time frames
   specified in paragraph (a)(1) of this section, the carrier shall:

   (1) Within thirty days of receiving the publisher's request, inform the
   directory publisher that the requested schedule cannot be accommodated
   and tell the directory publisher which schedules can be accommodated;
   and

   (2) Adhere to the schedule the directory publisher chooses from among
   the available schedules.
