Transition for DS1 and DS3 Loops. 2.1.4.1 For purposes of this Section 2, the Transition Period for the Embedded Base of DS1 and DS3 Loops and for the Excess DS1 and DS3 Loops (defined in 2.1.4.3) is the twelve (12) month period beginning March 11, 2005 and ending March 10, 2006. 2.1.4.2 For purposes of this Section 2, Embedded Base means DS1 and DS3 Loops that were in service for CBX One-Stop Covad as of March 10, 20052005 in those wire centers that, as of such date, met the criteria set forth in Sections 2.1.4.5.1 or 2.1.4.5.2 below. Subsequent disconnects or loss of End Users shall be removed from the Embedded Base. 2.1.4.3 Excess DS1 and DS3 Loops are those Covad DS1 and DS3 Loops in service as of March 10, 2005, in excess of the caps set forth in Sections 2.3.6.2 and 2.3.12 below, respectively. Subsequent disconnects or loss of End Users shall be removed from Excess DS1 and DS3 Loops. 2.1.4.4 For purposes of this Section 2, a Business Line is defined in 47 C.F.R. § 51.5. 2.1.4.4 BellSouth shall make available DS1 and DS3 Loops as defined in this Section 2. 2.1.4.5 Notwithstanding anything to the contrary in this Agreement, BellSouth and except as set forth in Section 2.1.4.12 below, AT&T shall make available DS1 and DS3 Loops as described in this Section 2.1.4 only for CBX One-Stop▇▇▇▇▇’s Embedded Base during the Transition Period: 2.1.4.4.1 2.1.4.5.1 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 2.1.4.5.2 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 2.1.4.6 The Master List of Unimpaired Wire Centers and AT&T’s List of Unimpaired Wire Centers as described in Section 1.8 sets forth the list of wire centers meeting the criteria set forth in Sections 2.1.4.5.1 and 2.1.4.5.2 above as of March 11, 2005. 2.1.4.7 Notwithstanding the Effective Date of this Agreement, during the Transition Period, the rates for CBX One-StopCovad’s Embedded Base of DS1 and DS3 Loops and Covad’s Excess DS1 and DS3 Loops described in this Section 2.1.4 shall be as set forth in Exhibit B. 2.1.4.6 2.1.4.8 The Transition Period shall apply only to CBX One-Stop(1) Covad’s Embedded Base and CBX One-Stop (2) Covad’s Excess DS1 and DS3 Loops. Covad shall not add new DS1 or DS3 loops Loops as described in this Section 2.1.4 pursuant to this Agreement, except pursuant to the self-certification process as set forth in Section 1.8 of this Attachment and as set forth in Section 2.1.4.12 below. 2.1.4.7 2.1.4.9 Once a wire center exceeds both of the thresholds set forth in Section 2.1.4.4.1Sections 2.1.4.5.1 and 2.1.4.5.2 below, no future DS1 Loop unbundling will be required in that wire center. 2.1.4.8 2.1.4.10 Once a wire center exceeds both of the thresholds set forth in Section 2.1.4.4.2Sections 2.1.4.5.1 and 2.1.4.5.2 below, no future DS3 Loop unbundling will be required in that wire center. 2.1.4.9 At the end 2.1.4.11 No later than December 9, 2005 Covad shall submit spreadsheet(s) identifying all of the Transition Period any Embedded Base of circuits and Excess DS1 and DS3 Loops to be either disconnected or converted to other AT&T services pursuant to Section 1.6 above. The Parties shall negotiate a project schedule for the Conversion of the Embedded Base and Excess DS1 and DS3 Loops. 2.1.4.11.1 If Covad fails to submit the spreadsheet(s) specified in Section 2.1.4.11 above for all of its Embedded Base and Excess DS1 and DS3 Loops prior to December 9, 2005, AT&T will identify Covad's remaining Embedded Base and Excess DS1 and DS3 Loops, if any, and will transition such circuits to the equivalent tariffed AT&T service(s). Those circuits identified and transitioned by AT&T pursuant to this Section 2.1.4.11.1 shall be disconnectedsubject to all applicable disconnect charges as set forth in this Agreement and the full nonrecurring charges for installation of the equivalent tariffed AT&T service as set forth in AT&T's tariffs. 2.1.4.11.2 For Embedded Base circuits and Excess DS1 and DS3 Loops converted pursuant to Section 2.1.4.11 above or transitioned pursuant to Section 2.1.4.11.1 above, the applicable recurring tariff charge shall apply to each circuit as of the earlier of the date each circuit is converted or transitioned, as applicable, or March 11, 2006.
