§  64.1508   Blocking access to 900 service.

   (a) Local exchange carriers must offer to their subscribers, where
   technically feasible, an option to block access to services offered on
   the 900 service access code. Blocking is to be offered at no charge, on
   a one-time basis, to:

   (1) All telephone subscribers during the period from November 1, 1993
   through December 31, 1993; and

   (2) Any subscriber who subscribes to a new telephone number for a
   period of 60 days after the new number is effective.

   (b) For blocking requests not within the one-time option or outside the
   time frames specified in paragraph (a) of this section, and for
   unblocking requests, local exchange carriers may charge a reasonable
   one-time fee. Requests by subscribers to remove 900 services blocking
   must be in writing.

   (c) The terms and conditions under which subscribers may obtain 900
   services blocking are to be included in tariffs filed with this
   Commission.
