Section 51.231 - Provision of information on advanced services deployment(a) An incumbent LEC must provide to requesting carriers that seek access to a loop or high frequency portion of the loop to provide advanced services: (1) Uses in determining which services can be deployed; and information with respect to the spectrum management procedures and policies that the incumbent LEC.(2) Information with respect to the rejection of the requesting carrier's provision of advanced services, together with the specific reason for the rejection; and(3) Information with respect to the number of loops using advanced services technology within the binder and type of technology deployed on those loops.(b) A requesting carrier that seeks access to a loop or a high frequency portion of a loop to provide advanced services must provide to the incumbent LEC information on the type of technology that the requesting carrier seeks to deploy.(1) Where the requesting carrier asserts that the technology it seeks to deploy fits within a generic power spectral density (PSD) mask, it also must provide Spectrum Class information for the technology.(2) Where a requesting carrier relies on a calculation-based approach to support deployment of a particular technology, it must provide the incumbent LEC with information on the speed and power at which the signal will be transmitted.(c) The requesting carrier also must provide the information required under paragraph (b) of this section when notifying the incumbent LEC of any proposed change in advanced services technology that the carrier uses on the loop. 65 FR 1345 , Jan. 10, 2000
