Notice of Network Changes If a Party makes a change in the information necessary for the transmission and routing of services using that Party’s facilities or network, or any other change in its facilities or network that will materially affect the interoperability of its facilities or network with the other Party’s facilities or network, the Party making the change shall publish notice of the change at least ninety (90) days in advance of such change, and shall use reasonable efforts, as commercially practicable, to publish such notice at least one hundred eighty (180) days in advance of the change; provided, however, that if an earlier publication of notice of a change is required by Applicable Law (including, but not limited to, 47 CFR 51.325 through 51. 335) notice shall be given at the time required by Applicable Law.
