supply the requesting service providers with interconnection or access, or any combination thereof. 3. In assessing the need to impose on a service provider the making available of reference offers, the Authority shall consider: a) Existing obligations applicable to the service provider pursuant to the present DecreeLaw or regulatory measures issued thereunder; b) The relative bargaining power of the service provider subject to the obligation and that of the other service providers requesting interconnection or access therefrom; and c) Whether such an imposition is essential to facilitate and assist the reaching of reasonable and fair agreements with other service providers. 4. If approved by the Authority, the reference offer may consist, in whole or in part, of an existing framework agreement. 5. If a service provider fails to comply with paragraph 1 of this article within a reasonable period of time set by the Authority, which shall, save in duly justified exceptional circumstances, be no less than 60 days, the Authority may, after consultation with the service provider, determine reference terms of interconnection or access, as applicable, in accordance with this Chapter.
