Sec. 51.809  Availability of provisions of agreements to other 
          telecommunications carriers under section 252(i) of the Act.

    (a) An incumbent LEC shall make available without unreasonable delay 
to any requesting telecommunications carrier any individual 
interconnection, service, or network element arrangement contained in 
any agreement to which it is a party that is approved by a state 
commission pursuant to section 252 of the Act, upon the same rates, 
terms, and conditions as those provided in the agreement. An incumbent 
LEC may not limit the availability of any individual interconnection, 
service, or network element only to those requesting carriers serving a 
comparable class of subscribers or providing the same service (i.e., 
local, access, or interexchange) as the original party to the agreement.
    (b) The obligations of paragraph (a) of this section shall not apply 
where the incumbent LEC proves to the state commission that:
    (1) The costs of providing a particular interconnection, service, or 
element to the requesting telecommunications carrier are greater than 
the costs of providing it to the telecommunications carrier that 
originally negotiated the agreement, or
    (2) The provision of a particular interconnection, service, or 
element to the requesting carrier is not technically feasible.
    (c) Individual interconnection, service, or network element 
arrangements shall remain available for use by telecommunications 
carriers pursuant to this section for a reasonable period of time after 
the approved agreement is available for public inspection under section 
252(f) of the Act.
