Notwithstanding anything to the contrary in this Agreement, BellSouth shall make available DS1 and DS3 Loops as described in this Section 2.1.4 only for Global CrossingStarlink’s Embedded Base during the Transition Period: 2.1.4.4.1 DS1 Loops at any location within the service area of a wire center containing 60,000 or more Business Lines and four (4) or more fiber-based collocators. 2.1.4.4.2 DS3 Loops at any location within the service area of a wire center containing 38,000 or more Business Lines and four (4) or more fiber-based collocators. 2.1.4.5 During the Transition Period, the rates for Global CrossingStarlink’s Embedded Base of DS1 and DS3 Loops described in this Section 2.1.4 shall be as set forth in Exhibit B. 2.1.4.6 The Transition Period shall apply only to Global CrossingStarlink’s Embedded Base and Global Crossing Starlink shall not add new DS1 or DS3 loops as described in this Section 2.1.4 pursuant to this Agreement. 2.1.4.7 Once a wire center exceeds both of the thresholds set forth in Section 2.1.4.4.1, no future DS1 Loop unbundling will be required in that wire center. 2.1.4.8 Once a wire center exceeds both of the thresholds set forth in Section 2.1.4.4.2, no future DS3 Loop unbundling will be required in that wire center. 2.1.4.9 At the end of the Transition Period any remaining Embedded Base will be disconnected.
