§ 51.209   Toll dialing parity.

   (a) A LEC shall implement throughout each state in which it offers telephone
   exchange service intraLATA and interLATA toll dialing parity based on LATA
   boundaries. When a single LATA covers more than one state, the LEC shall use
   the implementation procedures that each state has approved for the LEC
   within that state's borders.

   (b) A LEC shall implement toll dialing parity through a presubscription
   process that permits a customer to select a carrier to which all designated
   calls on a customer's line will be routed automatically. LECs shall allow a
   customer to presubscribe, at a minimum, to one telecommunications carrier
   for all interLATA toll calls and to presubscribe to the same or to another
   telecommunications carrier for all intraLATA toll calls.

   (c) A LEC may not assign automatically a customer's intraLATA toll traffic
   to  itself,  to  its  subsidiaries  or  affiliates,  to the customer's
   presubscribed interLATA or interstate toll carrier, or to any other carrier,
   except when, in a state that already has implemented intrastate, intraLATA
   toll dialing parity, the subscriber has selected the same presubscribed
   carrier for both intraLATA and interLATA toll calls.

   (d) Notwithstanding the requirements of paragraphs (a) and (b) of this
   section, states may require that toll dialing parity be based on state
   boundaries if it deems that the provision of intrastate and interstate toll
   dialing parity is procompetitive and otherwise in the public interest.
